Cosmetic ColorantIngredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
This ingredient is also called ethanol or ethyl alcohol. It is denatured, meaning made undrinkable for cosmetic use.
In formulas, it:
Is it bad for your skin?
The answer comes down to concentration. Patch and wash studies have found highly concentrated alcohol-based hand rubs (60-100%) cause less barrier disruption than washing with a basic detergent like SLS. The only measurable effect in these studies was a temporary dip in skin hydration.
Concentrations below 12-15% in leave-on cosmetics is generally well-tolerated. Concentrations above start to see increased transepidermal water loss (TEWL) and reduced hydration.
In concentrations about 58%, it creates temporary channels in your skin's lipid layers to become more permeable and allow other ingredients to slip through easily.
This ingredient can be up to 80% of the formula in alcohol-based perfumes.
Overall, this ingredient is probably harmless if found lower down an ingredients list but worth side-eyeing if it's high up (especially if your barrier is already struggling).
Alcohol can worsen dry skin, eczema, and oily skin, especially at higher concentrations. This is because it can increase transepidermal water loss and decrease hydration to disrupt the skin barrier.
According to the National Rosacea Society based in the US, you should be mindful of products with these alcohols in the top half of ingredients.
True allergic contact dermatitis to ethanol is uncommon, but be sure to patch test if you have dry or sensitive skin.

Topically, glycerin does several things at once:
Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
Just know very high concentrations (>40%) can feel tacky in low humidity.
Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

As an emulsifying agent, it helps other ingredients like fragrances and fat-soluble vitamins dissolve cohesively.
Due to its large molecule size, it doesn't penetrate beyond the skin's surface.
This ingredient has a solid regulatory track record; the CIR Expert Panel first concluded it was safe for use in cosmetics at concentrations up to 100% in 1997. A 2012 reassessment reaffirmed that finding. Safety studies have also found no irritation or evidence of toxicity.
A 2019 study did find this ingredient to grow Malassezia, so this ingredient may not be fungal acne safe.

It's often used in formulations along with Caprylyl Glycol to preserve the shelf life of products.
Pvp is a water-soluble synthetic polymer and common hairstyling ingredient. It is a film-forming ingredient and used to "hold" specific shapes of hair.
In cosmetics, PVP helps products like sunscreens and color cosmetics last longer and wear more evenly.
It is less effective in high-humidity. It tends to draw moisture, but this moisture dismantles the structure and "hold".
PVP is generally well tolerated on skin and toxicity studies are negative for dermal irritation.
Learn more about PvpSodium Dehydroacetate is a synthetic preservative and sodium salt form of dehydroacetic acid. It stops bacteria, mold, and yeast from growing in your products at low concentrations.
Clinical testing found it to be non-irritating, non-sensitizing, and non-photosensitizing. It's also not significantly absorbed through skin.
There are a very small number of reported cases of contact dermatitis in cases linked to wound-care creams used over compromised skin (rather than skincare).
Overall, this is a well-studied and low-risk preservative just doing its job.
Typical concentrations run up to 0.6%, which is also the maximum amount permitted under both EU CosIng regulations and US FDA guidelines.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!

You'll likely find this ingredient in mascaras, eyeliners, brow products, and eye shadow.
In the US, this ingredient can only be used if it meets strict FDA specifications. Certain versions even require batch-by-batch certification after extensive safety evaluation.
In the European Union, this ingredient is permitted as a colorant and classified as a "nanomaterial" based on its particle size (meaning it requires deeper assessment).
The EU Scientific Committee on Consumer Safety (SCCS) has reviewed nano-sized carbon black specifically and concluded that it does not pose a risk to human health when used in cosmetic products applied to healthy, intact skin and formulated to avoid inhalation.
Studies support this regulatory stance. Laboratory studies on nano-carbon black show potential for cytotoxicity and inflammatory effects in immune cells; it is important to highlight these findings are based on in vitro (not done on a living organism) testing or inhalation scenarios rather than normal topical cosmetic use.
Occupational studies involving industrial workers exposed to airborne carbon black have not shown a clear link between cumulative exposure and cancer risk. These findings are not directly applicable to cosmetics; cosmetic formulations bind pigments within creams, gels, and liquids that are not inhaled.
Overall, evidence shows that this ingredient is safe under regulatory guidelines and purity standards, especially when formulated to avoid airborne exposure.
Even with regulatory approval and a long history of use, some consumers might prefer to avoid ingredients that are petroleum-derived or that fall under the “nanomaterial” category.
Choosing whether to use CI 77266 isn’t necessarily about safety alone; it can also be about personal philosophy, comfort level with synthetic versus natural ingredients, and how much weight you place on ongoing research and regulatory oversight.
Makeup is highly individual, and personal preference plays an important role in deciding what feels right for you.
