Let's Clear The Air on "Clean Beauty"

Before we jump into ingredients, let’s talk about the term clean beauty. There's no such thing as clean beauty. It’s not about perfection, it’s about progress.

At its core, clean beauty isn’t a legally defined term as yet, and that’s okay. What it represents is a movement toward transparency, safer ingredients, ethical sourcing, and conscious consumption.

As a clean beauty entrepreneur, you’re not just formulating products, you’re helping shift an entire industry forward. And that’s powerful.

But before you add more botanical extracts or natural actives to your line, it’s equally important to understand what not to include.

Here are five toxic ingredients that still creep into conventional beauty products, and why they have no place in your clean, future-forward formulations.

Content

1. Parabens; Disrupting More Than Just Skin

Used In: Moisturizers, foundations, shampoos, conditioners

Aliases: Methylparaben, propylparaben, butylparaben, ethylparaben, n-propylparaben, isobutylparaben, benzylparaben, PHENONIP, Gemoben II, parahydroxybenzoate.

Parabens are preservatives used to extend shelf life by preventing mold and bacterial growth. But their convenience comes at a cost.

These synthetic chemicals can mimic estrogen, a hormone that regulates many processes in the body.

Studies have linked parabens to hormonal imbalances, early puberty in girls, and potential implications in breast cancer development.

While the data continues to evolve, many global markets, including the EU have restricted or banned some parabens.

For indie beauty brands, this is an opportunity. You don’t need to compromise safety for stability.

There are plant-based preservatives like leuconostoc (fermented radish root) or gluconolactone that offer protection without endocrine disruption.

2. Phthalates; The Silent Scent Saboteur

Used In: Fragrances, Nail Polish Lotions, Hair Sprays

Aliases: DEP(diethyl phthalate), DBP(dibutyl phthalate). BBP; butyl benzyl phthalate, mono benzyl phthalate, mono-n-butyl phthalate, di-n-butyl phthalate, mono-isobutyl-phthalate.

Phthalates are used to help fragrances stick to the skin and increase flexibility in plastics. The problem?

They’re hormone disruptors, too. Studies have shown links between phthalate exposure and reproductive toxicity, especially in developing babies and children.

Here’s the tricky part: phthalates often hide behind the word “fragrance” or “parfum” on ingredient labels, because companies are not required to disclose proprietary blends.

As a clean beauty founder, going fragrance-free or using essential oil-based natural scent blends can help you stand out to health-conscious consumers.

Transparency isn’t just good ethics, it’s good branding.

3. Formaldehyde; The Ingredient You Didn’t Know Was There

Used In: Eyelash glue, Keratin Hair Treatments, Nail Treatments

Aliases: Imidazolidinyl urea, DMDM hydantoin, Formalin, Methyl Aldehyde, Morbicid Acid, Oxymethylene, Diazolidinyl Urea, Sodium Hydroxymethylglycinate, Quaternium-15, 2-bromo-2-nitropropane-1,3-diol.

Formaldehyde isn’t always added directly to a product, it can be released slowly by preservatives known as “formaldehyde releasers.”

Even in small doses, this chemical has been classified as a human carcinogenic by the International Agency for Research on Cancer (IARC).

Aside from cancer concerns, formaldehyde can also cause respiratory issues, allergic skin reactions, and eye irritation, none of which belong in products meant to enhance beauty.

Safer preservation systems exist. By choosing formaldehyde-free raw materials, you ensure peace of mind for your customer and yourself.

4. SLS/SLES; Suds At A Steep Price

Used In: Cleansers, shampoos, toothpaste, body wash

Aliases: Sodium dodecyl sulfate, Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES).

Consumers often equate foam with effectiveness. But many foaming agents especially SLS and SLES are known to be harsh skin irritants. SLES, in particular, may be contaminated with 1,4-dioxane, a probable human carcinogen created during its manufacturing process.

For sensitive skin types or anyone with conditions like eczema or rosacea, these surfactants can do more harm than good.

Fortunately, many clean brands now opt for gentler, plant-derived surfactants like coco-glucoside, decyl glucoside, or sodium cocoyl isethionate, which cleanse effectively without stripping the skin.

5. Synthetic Fragrance; The Undisclosed Chemical Cocktail

Used In: Almost everything—lotions, lipsticks, cleansers, deodorants

Aliases: Fragrance, parfum

This is one of the most common, and the most ambiguous ingredients on beauty labels. “Fragrance” can legally include up to 3,000 undisclosed chemicals, many of which are derived from petroleum and may include allergens, endocrine disruptors, or phthalates.

Many beauty entrepreneurs opt for transparent fragrance policies, using essential oils, CO2 extractions, or isolating specific plant scent compounds. You don’t need to be a perfumer, just make sure your ingredients align with your brand values.

Tip: If you include natural fragrance, always list out the components (e.g., "Lavender Oil, Citrus Peel Extract") and offer unscented versions for sensitive skin types.

Why This Matters for Beauty Brand Founders.

Clean Formulation = Clear Differentiation

In a saturated market, ingredient integrity is one of the most powerful ways to differentiate yourself. Today’s beauty consumer is informed, skeptical, and loyal once they trust you.

That trust starts with transparency. It starts with education. And it starts with knowing which ingredients to ban from your line before you even design your first label.

Audit your ingredient lists: Go deeper than the marketing check your raw material suppliers and INCI listings.

Partner with ethical labs and formulators: Not all labs are equal. Choose partners who understand your commitment to non-toxic, plant-based, and transparent beauty.
