Vegan Cosmetics Analysis: Animal-Derived Ingredients in Beauty Products

The Hidden Side of Your Makeup Bag: Are Cosmetic Products Really Vegan?

When buying lipstick, we look at the color; when buying foundation, we look at the shade; and when buying cream, we look at the scent. But have you ever stopped to think about what ingredients are actually in these products? Unfortunately, many of the products in our makeup bags contain animal-derived ingredients without us even realizing it.

Animal-derived ingredients are so common in the cosmetics industry that they’re often hidden on labels or not fully disclosed to consumers. Carmine, lanolin, gelatin, honey, milk, collagen, elastin, glycerin, stearic acid… All of these can be of animal origin. But here’s the interesting part: today, plant-based or synthetic alternatives exist for all of these ingredients.

A Critical Note: The beauty industry is one of the areas where consumers are most sensitive. Products adorned with terms like “natural,” “organic,” or “plant-based” may actually contain animal-derived ingredients. For example, a “natural” lipstick might owe its bright red color to carmine derived from the cochineal insect. As consumers, we must look not only at the packaging but also at the ingredients.

What Are the Animal-Derived Ingredients Used in Cosmetics?

Let’s list the most common animal-derived ingredients found in cosmetic products:

• Carmine (E120 - CI 75470): A red dye derived from the cochineal insect. It is used in products such as lipstick, eyeshadow, blush, nail polish, and lip gloss.
• Lanolin: An oily substance derived from sheep’s wool. It is used as a moisturizer in products such as creams, lotions, lip balms, and soaps.
• Gelatin: Derived from animal bones and skin. It is used as a thickening agent in products such as mascara, nail polish, and gel creams.
• Honey and Milk Derivatives: Used as moisturizers and emollients in many creams and lotions.
• Collagen and Elastin: Derived from animal skin, bones, and connective tissues. They are used in anti-aging products, creams, and serums.
• Glycerin: Used as a moisturizer. It can be plant-based or derived from animal fats.
• Stearic Acid: Can be derived from animal fats. It is used as a thickening agent in creams, lotions, and soaps.
• Squalene / Squalane: It can be derived from shark liver or from olives. It is used as a moisturizer.
• Keratin: It is derived from animal hair, horns, and nails. It is used in hair care products.
• Isinglass (Fish Glue): It is derived from the swim bladders of fish. It is used in some nail polishes and cosmetics.

An Interesting Detail: The term “animal-derived” is not explicitly listed on a product label. Instead, it is disguised under names such as “collagen,” “elastin,” “keratin,” or “lanolin.” That’s why it’s essential to improve your label-reading skills.

What Are Vegan Cosmetics and What Ingredients Do They Use?

Vegan cosmetic products contain no animal-derived ingredients and are not tested on animals. Instead, they use the following ingredients:

• Plant-Based Colorants: Natural or synthetic colorants such as beetroot, carrot oil, turmeric, chlorophyll, and iron oxides.
• Plant-Based Oils and Waxes: Shea butter, cocoa butter, jojoba oil, coconut oil, candelilla wax, carnauba wax (plant-based).
• Plant-Based Moisturizers: Aloe vera, glycerin (plant-based), hyaluronic acid (microbial), panthenol (plant-based).
• Plant-Based Collagen and Elastin: Collagen alternatives derived from plants such as wheat, corn, and soy.
• Essential Oils: Natural fragrances derived from plants such as lavender, mint, eucalyptus, tea tree, and rose.
• Mineral Pigments: Mineral-based colorants and sunscreens such as titanium dioxide, zinc oxide, and iron oxide.

How Is a Vegan Cosmetic Analysis Performed?

The process we at Nanocert follow to verify that a cosmetic product is truly vegan:

1. Ingredient Screening

All of the product’s ingredients are examined one by one. Any substance that may be of animal origin—such as carmine, lanolin, gelatin, collagen, elastin, honey, the source of glycerin, the source of stearic acid, the source of squalene, and keratin—is investigated.

2. Laboratory Testing

Product samples are sent to a laboratory. They are tested for the presence of animal DNA or protein residues. This is a critical step, particularly for verifying ingredients with an unclear source (such as glycerin).

3. Supplier Audit

Not only the product but also the supply chain is inspected. Suppliers of the ingredients used must provide documentation proving that the ingredients are not of animal origin.

4. Production Process Review

The equipment used in the production of cosmetic products is examined to determine whether it has come into contact with animal-derived products. If there is a risk of cross-contamination, precautions must be taken.

What Should You Look for When Buying Vegan Cosmetics?

• Read the Label Carefully: Watch out for terms such as “carmine,” “lanolin,” “gelatin,” “collagen,” “elastin,” “honey,” “milk,” and “keratin.”
• Question Ingredients with Unclear Sources: Research the sources of ingredients like “glycerin,” “stearic acid,” and “squalane.”
• Choose Certified Products: There is a big difference between a product labeled “vegan” and one that is “vegan-certified.”
• Research the Brand: Visit the brand’s official website. Learn about its stance on veganism and cruelty-free practices.
• Look for the Nanocert Vegan Certification: When you see the Nanocert logo on products, you can be sure they’ve undergone reliable testing and analysis processes.

The Greenwashing Trap in the Cosmetics Industry

Unfortunately, as the vegan cosmetics market grows, so does greenwashing. Some brands use terms like “natural,” “organic,” or “plant-based” to market their products as if they were vegan. For example, a lipstick containing plant-based oils but colored with animal-derived carmine may appear “natural” but is not vegan.

Remember: A truly vegan cosmetic product contains no animal-derived ingredients and has not been tested on animals at any stage of the production process.
