A Real Talk from Your Cosmetic Chemist


If you’ve been in my community for any length of time, you already know this: I love safe,

well-formulated products. I love transparency. I love ingredient literacy. And I love empowering you with real science.


But there is one trend that continues to grow louder every year — the idea of “non-toxic” and “chemical-free” cosmetics.


Let’s talk about it honestly.


Because the truth is... the phrase “chemical-free” doesn’t mean what people think it means.


Everything Is a Chemical


Everything.

Water? A chemical.

Oxygen? A chemical.

Shea butter? A mixture of chemicals.


Lavender essential oil? A complex blend of hundreds of naturally occurring chemical

compounds.


The word chemical simply refers to a substance with a defined molecular structure.

Water is H2O — two hydrogen atoms bonded to one oxygen atom. That’s chemistry.

And here’s something important I teach my students:


Even water can be deadly.

If you inhale too much water, you can drown.

If you drink excessive amounts in a short period, you can develop water intoxication

(hyponatremia), which can be life-threatening.


Does that make water toxic?

No.

It means dose and exposure matter.


And that’s where most online fear-based marketing falls apart.


“Non-Toxic” Is Not a Scientific Category

In toxicology, nothing is inherently “toxic” or “non-toxic.”

There is:

  • Hazard

  • Dose

  • Route of exposure

  • Duration of exposure

  • Population risk


This is foundational toxicology.


Even vitamin A (retinol) can be toxic at high doses.

Even essential oils — yes, even the “natural” ones — can cause sensitization, irritation, or

systemic toxicity when misused.


The famous quote from Paracelsus still holds true:

“The dose makes the poison.”

That principle has not changed in 500 years.


Why “Non-Toxic” Claims Can Create Compliance Issues?

Here’s the part many brands don’t realize:

Advertising a cosmetic product or ingredient as “non-toxic” can create regulatory problems.

Why?

Because calling your product “non-toxic” implicitly suggests that competing cosmetic products, including those formulated with FDA- or Health Canada–approved raw materials are toxic.


That implication can be interpreted as:

  • Misleading comparative advertising

  • Fear-based marketing

  • Unsupported safety superiority claims


Regulatory agencies do not recognize “non-toxic” as a defined cosmetic classification. There is no formal threshold that qualifies a product as “toxic” or “non-toxic.” Cosmetics are required to be safe for their intended use under labeled conditions — period.


When a brand markets something as “non-toxic,” it can be viewed as:

  • An unsubstantiated safety claim

  • A disparaging claim against legally compliant products

  • A misleading oversimplification of toxicology


In recent years, regulatory bodies have paid closer attention to these types of marketing claims because of the alarming rise in fear-driven campaigns.


The Rise of Fear-Based Marketing


We’ve seen a significant trend of marketing built on:

  • “Toxin-free”

  • “Chemical-free”

  • “Free from poisons”

  • “No dangerous chemicals”


These phrases are designed to trigger anxiety.


But cosmetics sold legally in North America and the EU are already required to meet safety

standards. Approved raw materials are assessed for:


  • Dermal exposure limits

  • Margin of safety

  • Reproductive toxicity data

  • Irritation and sensitization potential

  • Cumulative exposure


Suggesting that other compliant cosmetic products are “toxic” undermines public trust in

regulatory systems and in science.


And that’s exactly why regulators have begun discouraging — and in some contexts challenging — these types of claims.


The Problem With “Ingredient Scanner” Apps


Let’s talk about the apps.

You’ve probably seen them. You scan a barcode and instantly get a red, yellow, or green rating.

Sounds empowering, right?

Here’s what they don’t tell you:


1. They Do Not Account for Percentage Used


An ingredient used at 0.2% is not the same as an ingredient used at 20%.


Cosmetic formulas are built in percentages. Many ingredients flagged as “dangerous” are used at extremely low, regulated levels that fall far below toxicological thresholds.


Toxicology is math.

Apps rarely show you the math.


2. They Ignore Method of Exposure


There is a massive difference between:

  • Inhalation

  • Ingestion

  • Leave-on dermal exposure

  • Rinse-off dermal exposure


An ingredient studied at high oral doses in animal models is not equivalent to applying 0.5% in a rinse-off cleanser.

Exposure pathway matters.

A lot.


3. They Don’t Account for Regulatory Limits


Cosmetic chemists formulate within:

  • IFRA guidelines (for fragrance)

  • Health Canada regulations

  • FDA regulations

  • EU Cosmetic Regulation

  • SCCS safety assessments

  • CIR reviews


These regulatory frameworks are built on toxicological data and safety margins.

Apps often simplify decades of safety science into a color code.

Science is not a traffic light.


Natural Does Not Automatically Mean Safer


This is one I say often in my classes.


Poison ivy is natural.

Arsenic is natural.

Botulinum toxin is natural.

Nature is chemistry.


Synthetic ingredients are not automatically harmful. Natural ingredients are not automatically

safe.


What matters is:

  • Purity

  • Stability

  • Concentration

  • Formulation compatibility

  • Preservative system

  • Packaging

  • Consumer usage patterns


When I formulate, I’m thinking about all of that.


Fear-Based Marketing Hurts Small Brands

This is something I care deeply about.

I’ve watched beginner formulators panic because an app labeled one ingredient in their formula as “toxic.”


Often that ingredient:

  • Has decades of safe cosmetic use

  • Is approved globally

  • Is used well below safety thresholds

  • Is necessary for stability or preservation


And now the formulator feels shame or fear.

That’s not how education should work.

We should empower people with understanding — not scare them with oversimplification.


Why Long Names Sound Scary

“Sodium Hyaluronate” sounds scarier than “hyaluronic acid,” right?

But they are related forms of the same molecule.

“Phenoxyethanol” sounds more intimidating than “rose essential oil.”


Yet rose essential oil contains natural components that are far more likely to cause sensitization than properly used phenoxyethanol.


The length of a name does not determine its safety. Remember, ingredient lists are not written in layman’s terms. They are written in INCI (International Nomenclature of Cosmetic

Ingredients), which uses a combination of Latin (for botanicals), English (for common materials), and scientific chemical nomenclature.


Chemistry terminology is descriptive — not dangerous.


As a cosmetic chemist — and as someone who built this career to make sure my own family

had safer products — I promise you this:

Science is on your side.


Let’s move away from fear-based marketing and toward ingredient literacy. Let’s make and love natural products for the right reasons.


That’s how we truly create safer cosmetics.

What I Wish I Understood Sooner as a Formulator?

When I first started formulating, I automatically assumed unrefined meant superior.

Raw. Pure. Straight from nature.

It felt like the better choice.

But as I deepened my studies in cosmetic chemistry and began developing products for clients,

I realized something important:

Refined and unrefined ingredients are tools — and each tool has a purpose.

Let’s break this down properly.


What Does “Unrefined” Actually Mean?

Unrefined oils and butters are minimally processed after extraction.

They typically undergo:

  • Mechanical pressing (cold pressing or expeller pressing)

  • Filtration to remove solid debris

  • No deodorizing

  • No bleaching

  • No chemical refining steps



They retain more of their natural:

  • Color

  • Aroma

  • Plant sterols

  • Unsaponifiables

  • Minor phytonutrients

Example: Unrefined Shea Butter


Unrefined Shea Butter:


  • Cream to yellow color

  • Strong nutty, smoky scent

  • Contains natural latex traces

  • Rich in unsaponifiables and triterpenes


Beautiful? Yes.

Always practical? No.


What Is “Refined”?

Refined oils and butters go through additional processing steps that may include:

  • Degumming

  • Neutralization

  • Bleaching (using clay filtration, not chlorine)

  • Deodorization

  • Winterization (for some oils)


This removes:

  • Strong scent

  • Natural pigments

  • Free fatty acids

  • Some oxidative components

  • Particulate matter


Example: Refined Shea Butter

Refined Shea Butter:

  • Bright white

  • Odorless

  • More uniform texture

  • Better suited for fragranced products


The Differences That Actually Matter in Formulation


1. Batch Consistency

Unrefined ingredients vary crop to crop.


  • Climate.

  • Harvest timing.

  • Storage.

  • Oxidation level.


If you are selling products and want identical batches every time, refined materials provide

better reproducibility.


2. Oxidative Stability

Unrefined oils contain more minor plant components. Some of these act as antioxidants — but others can accelerate instability.


Refined oils often have:

  • Lower peroxide values

  • More stable scent profile

  • Reduced discoloration over time


In warm climates, especially, this matters.


3. Fragrance Compatibility

I cannot stress this enough.


If you are creating:

  • Perfumed body creams

  • Fragrance-forward butters

  • Luxury emulsions


Unrefined butters can overpower your scent system and will definitely alter the final fragrance profile of your product.


That rich chocolate note in raw cocoa butter?

It will compete.


Refined oils allow your fragrance composition to remain true.


4. Final Product Appearance

In emulsions, unrefined materials can:

  • Darken your product

  • Shift color over time

  • Cause slight scent drift


Refined materials support:

  • Consistent in color emulsions

  • Clean aesthetic

  • Visual stability

If you are positioning your brand as luxury, aesthetics matter.


When I Personally Choose Unrefined

There are times I absolutely love unrefined materials.


I use them in:

  • Rustic body balms

  • Earthy anhydrous salves

  • Products where the natural scent complements the profile

  • Teaching ingredient identity


Unrefined Cocoa Butter

Unrefined Cocoa Butter brings warmth and character — but I use it intentionally.

Not automatically.


A Little Chemistry Perspective

Both refined and unrefined oils are primarily:

  • Triglycerides

  • Built from fatty acids and glycerol

  • Structurally similar at the core


The refining process does not change the fatty acid composition significantly.

It removes minor components.


That’s important to understand — because marketing often exaggerates the difference.


The Biggest Mistake I See Beginners Make

Choosing unrefined solely because it “sounds better.”


If your fragrance clashes...

If your cream discolors...

If your product oxidizes faster...

If your batches vary...


You will wish you had chosen differently.


Start stable.

Start controlled.

Then experiment.


Final Thoughts from Me to You


There is no superior choice.


There is only:

Appropriate for the formulation

Appropriate for the target market

Appropriate for the climate

Appropriate for your stability goals


I formulate based on science, not trends.


And once you understand the functional differences between refined and unrefined materials, your formulations become intentional — not emotional.


And that’s when you start formulating like a chemist.


With love and formulation precision,

The growth of handmade beauty has sparked amazing curiosity and innovation. Watching people explore ingredients, ask questions, and build confidence in formulation is one of my favorite parts of this industry.

But there is one area where excitement has to pause and serious caution needs to step in.

Sun protection.

I see creators online sharing recipes for “natural,” “chemical-free,” or “non-toxic” UV products almost daily. And I’ll be honest — every time I come across one, it makes my stomach tighten a little.

Not because plant-derived materials are somehow inferior.Not because independent makers lack talent.

It’s because this category carries medical, legal, and ethical responsibility that goes far beyond typical skincare.


Why the Language Matters


Let’s clear up two phrases that appear constantly.


Chemical-free is scientifically impossible.Water is a chemical. Shea butter is a chemical. Zinc oxide is a chemical. Everything we use in formulation is made of chemicals.


Non-toxic is also complicated. In many regions it is considered regulated or misleading terminology because it can imply that approved, commercially available products are toxic or dangerous. Those products have gone through safety assessments, regulatory review, and mandated testing. Suggesting otherwise can cross into false advertising territory.

Using these buzzwords might sound appealing in marketing, but they create inaccurate comparisons and potential legal problems.


Why This Category Is Different


Ultraviolet filters are not about moisturization or skin feel. They are about preventing burns and reducing long-term damage.


When someone reads an SPF value, they assume it has been verified through standardized testing. They are trusting the number. If that trust is misplaced, the result is not just disappointment — it can be injury. Sunscreens are classified as drugs or quasi-drugs in most countries.

Training Isn’t the Same as Testing

Knowing how to build emulsions, create stable dispersions, and select appropriate raw materials is essential — but education does not replace formal validation.

I was trained as a cosmetic chemist and taught how to design compliant UV protection systems. And I still don’t manufacture them.

Why? Because once a prototype is made, it must be submitted for efficacy testing to confirm that it truly delivers the protection level it claims. That process is specialized, expensive, and time-consuming, often involving multiple rounds if the first submission fails.

Having the knowledge to formulate and having verified performance data are two very different things.


The Real Danger of DIY Claims

A balm containing minerals is not automatically protective.A visible white layer is not proof of coverage.Thicker is not necessarily better.

Protection depends on microscopic distribution and film integrity. Gaps cannot be seen without specialized equipment, and failures usually become obvious only after the skin has already been harmed.


The desire to make products that feel wholesome and safe is admirable. Yet responsible formulation also means recognizing when a category requires resources beyond a home lab.

And ultraviolet protection is one of those categories.

If you'd like, I can next explain what actually happens inside a testing facility, why prototypes often fail even when the math looks perfect, or how regulatory agencies evaluate claims.


There Are Great Natural Options Available

Choosing mineral protection from established, compliant brands is completely valid. Natural does not mean ineffective — it simply means professionally developed and tested.



UV Radiation Basics

Sunlight includes wavelengths that can harm the skin, typically between 290 and 400 nm.

Melanin offers some natural defense, so deeper skin tones often have a higher inherent resistance to burning, but no skin type is immune to damage.

Exposure risk changes depending on:

  • time of day (strongest mid-day)

  • altitude and season

  • reflective environments like snow or water

  • clothing coverage


Types of UV Filters


Organic (Chemical) Filters

These absorb radiation and transform it into heat.

Common examples include:

  • Oxybenzone

  • Octinoxate

  • Homosalate

  • Ethylhexyl salicylate

Each one protects a specific slice of the spectrum, so blends are usually necessary.


Inorganic (Mineral) Filters

These primarily scatter and reflect radiation, while also absorbing some.

Examples:

  • Zinc oxide

  • Titanium dioxide

Their effectiveness depends heavily on particle size and dispersion quality.


Zinc Oxides

When people begin exploring mineral protection, one of the first surprises is that the same INCI name can describe materials that behave very differently in a formula.

I was recently asked whether the grade used in a deodorant is the same as the one used in a sun product.

The honest answer is: yes… and no.

They may all be labeled zinc oxide, but particle size, surface treatment, and physical format dramatically change how they perform, how they disperse, and what they are suitable for.

Let’s look at the common variations you’ll see from MakingCosmetics and how they differ.


Zinc Oxide (USP)

This is the traditional white powder many formulators first encounter.

Typical supplier notes describe it as:

  • pharmaceutical / cosmetic grade

  • non-nano, larger particle size

  • widely used for skin protectant applications

  • provides opacity and whitening

  • commonly used in diaper care, calamine-type products, and deodorants

Because the particles are relatively large, it tends to leave a visible white film and is not optimized for high-transparency UV applications.


Micronized Zinc Oxide

Here, the particles are milled much smaller.

According to supplier descriptions, this version offers:

  • improved spreadability

  • reduced whitening compared to USP grade

  • better aesthetic properties

  • suitability for UV protection systems

However, smaller particles also mean stronger tendencies to clump, making dispersion technique critical.


Micronized & Coated Zinc Oxide

Surface treatment is where things become more advanced.

Suppliers typically explain that coatings:

  • improve compatibility with oils and silicones

  • enhance dispersibility

  • increase photostability

  • help prevent unwanted reactions with other ingredients

  • improve transparency on the skin

This is often the type used in modern elegant mineral formulas.


Zinc Oxide Dispersions / Pastes

Instead of a dry powder, the mineral is pre-distributed into a carrier.

Supplier information usually highlights that dispersions:

  • simplify manufacturing

  • improve uniformity

  • reduce airborne particles

  • help achieve more consistent film formation

  • are easier to scale

They are designed to remove part of the technical burden from the formulator.


Why the Difference Matters

Even though the label says zinc oxide in every case, these materials behave differently in:

  • viscosity

  • whitening effect

  • compatibility

  • required processing equipment

  • final performance


Using the deodorant grade in a UV product will not magically produce the same outcome as a professionally engineered dispersion.

INCI names tell us identity. They do not tell us engineering.

Whenever you source minerals, the technical data sheet and supplier description matter just as much as the ingredient name.
