What if your daily makeup routine is exposing you to a cocktail of synthetic ingredients you would never willingly choose for your clean-living lifestyle?

Millions of women carefully choose organic food, grass-fed beef, natural skincare, and clean household products, yet continue applying conventional eyeliner around their eyes without reading a single ingredient on the label.

It’s time to question that habit.

Major cosmetics companies formulate eyeliners for intense color, waterproof performance, and all-day wear. That can mean using synthetic polymers, silicones, preservatives, and other ingredients that people pursuing a more natural lifestyle may prefer to avoid. Some cosmetic products across the industry have also contained PFAS, the persistent chemicals commonly known as “forever chemicals.”

Certain PFAS have been associated with serious health effects, including some cancers. However, the risks vary considerably among individual compounds, and finding an ingredient in a cosmetic does not automatically mean that normal use of the product causes cancer.

The bigger question is why consumers should blindly trust a famous beauty brand when they can look for simpler formulas with ingredients that better align with their clean-living values.

1. Maybelline: Synthetic Polymers, Silicones, and Preservatives

Maybelline is a drugstore staple, but its long-wear formulas illustrate why ingredient-conscious consumers should look beyond marketing claims.

For example, published ingredient lists for some Maybelline liquid and pencil eyeliners include ingredients such as acrylate copolymers, phenoxyethanol, butylene glycol, synthetic waxes, and silicone-based compounds. These ingredients serve different purposes, including film formation, moisture retention, texture, and preservation.

Maybelline’s TattooStudio Gel Pencil formulas have also listed ingredients such as trimethylsiloxysilicate, polyethylene, and synthetic fluorphlogopite, depending on the product and shade.

These are not the simple plant-oil-and-wax ingredients that many clean-living consumers look for when choosing a more natural cosmetic. Some shoppers prefer to minimize synthetic polymers and certain preservatives because of personal ingredient standards, sensitivity concerns, or environmental considerations.

What about cancer? Some cosmetic ingredients have been investigated for potential health effects, but the presence of a synthetic ingredient does not establish that an eyeliner causes cancer. The precise formula must be checked before making claims about particular hazardous substances.

If your goal is a more natural makeup bag, examine the individual product rather than assuming a familiar name guarantees a naturally formulated eyeliner.

2. MAC Cosmetics: Professional Makeup Is Not the Same as Natural Makeup

MAC has earned a reputation for professional pigmentation and long-lasting performance. But professional-quality makeup and a minimalist, plant-based ingredient profile are two different things.

Some MAC liquid eyeliners use synthetic film-forming polymers, preservatives, glycols, and silicone-based ingredients to help create the texture, color, and wear characteristics consumers expect.

These ingredients are not automatically toxic, but they illustrate how conventional cosmetics can rely on synthetic formulation technology rather than an exclusively botanical approach.

Consumers concerned about PFAS should also know that PTFE and certain other fluorinated ingredients have been used in some cosmetics across the industry. Certain PFAS have been associated with serious health effects, including particular cancers. However, that does not establish that every MAC eyeliner contains PFAS or that a particular product causes cancer.

The clean-living takeaway: Don’t confuse luxury branding, professional performance, or a high price with natural ingredients. Check the exact product and decide whether its formula meets your standards.

3. Urban Decay: Long-Wear Formulas Deserve a Closer Look

Urban Decay is known for bold colors, waterproof makeup, and products designed to stay in place. For consumers trying to reduce unnecessary synthetic ingredients, its individual formulas deserve the same scrutiny as those of other major beauty companies.

Some Urban Decay eyeliner formulas list ingredients such as hydrogenated polyisobutene, trimethylsiloxysilicate, isododecane, synthetic waxes, and other film-forming compounds. These ingredients contribute to texture, adhesion, and durability.

They are not all toxic, and synthetic does not automatically mean dangerous. Nevertheless, someone seeking a predominantly plant-derived eyeliner may reasonably prefer a different formulation.

PFAS are another category worth understanding. Certain PFAS have been linked to serious health effects, including some cancers, while many are highly persistent in the environment. However, a waterproof label alone does not prove that a product contains PFAS.

Instead of buying based solely on a promise of 24-hour wear, consider whether you really need that performance—or whether a simpler pencil would suit your everyday routine just as well.

4. L’Oréal Paris: The Ingredient List Matters More Than the Advertising

L’Oréal Paris offers a wide range of eyeliners, including liquid, gel, and waterproof formulas. Their ingredients vary by product, so it would be inaccurate to claim that every eyeliner from the brand has the same chemical profile.

When reviewing conventional eyeliner, look for synthetic film-forming polymers, silicones, and preservatives. Some consumers prefer to avoid certain ingredients because of skin sensitivities, environmental considerations, or a desire for a simpler formulation.

Another ingredient worth understanding is BHT, or butylated hydroxytoluene, which appears in some cosmetic formulations. It has been studied for potential biological and toxicological effects, but its presence alone is not proof that a cosmetic causes cancer.

The same caution applies to other ingredients that have raised questions in laboratory studies: the specific substance, dose, exposure route, and quality of evidence matter.

If you prefer a more natural lifestyle, you don’t have to choose a product simply because it is popular. Read the label, investigate the ingredients, and choose a formula that aligns with your personal standards.

5. Rimmel London: Affordable Makeup Still Deserves an Ingredient Audit

Rimmel London offers accessible, budget-friendly cosmetics, but a low price should never be the only factor in your decision.

When evaluating its eyeliners, check the exact product and shade for synthetic waxes, film-forming polymers, silicones, preservatives, and any ingredients you personally prefer to avoid. Do not assume that every product from a single brand has the same composition.

Another concern applies to eye makeup generally: contamination with heavy metals. The FDA warns that certain traditional products sold as kohl, kajal, or surma have contained high levels of lead. These products are not the same as ordinary Rimmel eyeliner, and the warning should not be used to imply that Rimmel products contain dangerous amounts of lead.

Lead is a toxic heavy metal, and unnecessary exposure should be avoided. Buy eye makeup from reputable sources and avoid products with missing ingredient declarations or uncertain origins.

The goal is not to panic about every ingredient with a scientific name. It is to stop assuming that a familiar brand name automatically means a product is naturally formulated.

Ingredients Clean-Living Consumers Should Know About

If you’re moving toward a more natural beauty routine, these are some of the ingredients and categories worth researching before purchasing eyeliner.

• PFAS, including PTFE: Certain PFAS have been associated with cancer and other adverse health effects. Many persist in the environment for long periods. The FDA has documented their use in some cosmetics and identified significant gaps in the safety data for many cosmetic PFAS. Not every PFAS has the same risk profile, and you should not assume a product contains them without evidence.
• BHT: A synthetic antioxidant used in some cosmetic formulas to help protect ingredients from deterioration. It has been investigated for potential biological and toxicological effects, but the presence of BHT in a cosmetic does not establish that the product causes cancer.
• Phenoxyethanol: A preservative used to help prevent microbial growth. Some consumers prefer alternative preservation systems, although phenoxyethanol is permitted in cosmetics within established concentration limits in many markets. It is not established as a human carcinogen at normal permitted cosmetic concentrations.
• Synthetic acrylate polymers: Film-forming ingredients used to help liquid eyeliner adhere to the skin and resist smudging. Their presence indicates a synthetic formulation, not proof of cancer risk. Some consumers choose to limit synthetic polymers for personal or environmental reasons.
• Silicones and synthetic waxes: Ingredients such as simethicone, trimethylsiloxysilicate, and synthetic waxes can improve spreadability and staying power. They are not automatically carcinogenic, but they may not fit the preferences of someone seeking a primarily botanical formula.
• Carbon black and other pigments: Pigment safety depends on the specific substance, its purity, and whether it is permitted for use around the eyes. Industrial exposure findings should not automatically be applied to properly manufactured cosmetic-grade pigments.
• Lead and other heavy-metal contaminants: Lead is a serious toxicological concern. Certain traditional eye cosmetics have contained high levels of lead, which is why ingredient declarations, product sourcing, and contamination controls matter.

For further reading, consult the FDA’s information on PFAS in cosmetics, eye cosmetic safety, and lead in cosmetics.
