More and more consumers are scrutinizing the labels of their skincare products. Faced with an often long and complex INCI list, some ingredients raise doubts. This is the case with alcohol, which is frequently singled out. Should it be avoided? Is it incompatible with a skin-friendly routine? To get a clear picture, it's essential to understand what lies behind this generic term and to distinguish between the different types of alcohol used in organic cosmetics.

The different types of alcohol in cosmetics

The word "alcohol" encompasses very different molecules. Here are those you may encounter in your skincare products, especially certified organic ones:

• Alcohol or Alcohol denat.: This refers to ethanol, often of plant origin (such as beet or sugar cane). It is used for its antimicrobial, preservative, and solubilizing properties. "Denat." means it has been denatured to make it unfit for consumption, according to current regulations.
• Benzyl alcohol: Naturally present in certain essential oils or plants (jasmine, ylang-ylang…), it is also authorized as a synthesized preservative, in small doses. It is one of the 26 regulated allergens, so its dosage is strictly controlled.
• Fatty alcohols: These are the good ones! Among them: cetyl alcohol, stearyl alcohol, cetearyl alcohol, lauryl alcohol, myristyl alcohol… These "fatty" alcohols are texturizing agents. They are used as emulsifiers (allowing water and oil to mix), thickeners, or emollients. They have a soft feel and help maintain skin comfort.

In certified organic cosmetics like Cosmébio or Ecocert, the use of these ingredients is strictly controlled, both in terms of origin and concentration.

What is the role of alcohol in cosmetic formulations?

Alcohol plays several roles in a cosmetic product:

• Preservative: It prevents bacterial growth and extends the product's shelf life without resorting to synthetic preservatives prohibited in organic products.

• Solvent: It dissolves certain active ingredients (especially plant extracts) or ensures the proper dispersion of fragrances.

• Fresh sensation: Its rapid evaporation creates a feeling of lightness upon application.

• Penetration enhancer: It can facilitate the absorption of active ingredients by the skin.

In organic cosmetics, alcohol is always used judiciously. Its concentration is limited, and it is combined with other gentle active ingredients to minimize its drying effects.

Alcohol and skin: what should you look out for?

Alcohol itself is not harmful. However, its impact depends on several factors: type of alcohol, concentration, frequency of use, and skin type.

• On sensitive or reactive skin, a high concentration of ethanol can lead to redness, tightness, or discomfort. The reason: its ability to dissolve the lipids of the skin barrier.

• Benzyl alcohol, although present in many organic skincare products, can be allergenic. If you are prone to allergies, it is better to do a preliminary test or opt for formulas without listed allergens.

• As for fatty alcohols, they are generally very well tolerated, even by delicate skin. They are often used in rich creams and lotions for their sensory and protective qualities.

Note: in a well-formulated product, alcohol is rarely isolated. It is accompanied by active ingredients such as vegetable oils, butters, or soothing extracts, to balance its effects.

How to spot alcohol in your cosmetics?

The INCI list (International Nomenclature of Cosmetic Ingredients) is the key to knowing what a product contains. Here are some tips:

• If alcohol is at the top of the list, its concentration is high. Prioritize formulas where it is lower down the list.

• Check for the presence of benzyl alcohol if you are prone to allergies.

• Organic certifications are a guarantee: they limit concentrations and prohibit certain aggressive or petrochemical-derived forms of alcohol.

You can also refer to the Cosmébio label, which offers increased transparency on compositions. Their article on alcohol in cosmetics is an excellent resource for further reading: read the Cosmébio article.

In summary

Alcohol in organic cosmetics is not an enemy. It has its place when well-formulated, in synergy with other gentle ingredients. The key is to observe the composition, know the different types of alcohol, and adapt your choices to your skin. Beauty begins with understanding what you apply to yourself every day.
