What purpose does alcohol have as an ingredient in skin care products? Is alcohol drying to the skin?
ALCOHOL FREE
For many years cosmetic manufacturers have marketed certain
cosmetic products that do not contain ethyl alcohol
(also known as ethanol, or grain alcohol) as "alcohol free."
Some consumers select "alcohol free" products because they
believe ethyl alcohol dries out their skin or hair.
However, "alcohols" are a large and diverse family of
chemicals, with different names and a variety of effects on
the skin. This can lead to some confusion among consumers
when they check the ingredient listings on cosmetic labels
to determine alcohol content.
In cosmetic labeling, the term "alcohol," used by itself,
refers to ethyl alcohol. Cosmetic products, including those
labeled "alcohol free," may contain other alcohols, such as
cetyl, stearyl, cetearyl, or lanolin alcohol. These are
known as fatty alcohols, and their effects on the skin
are quite different from those of ethyl alcohol.
Isopropyl alcohol, which some consumers may think of as
drying the skin, is rarely used in cosmetics. It is used in our Skin Prep Toner however.
The purpose is for prepping the skin for a peel which
involves deep cleaning and oil removal on the surface of the skin.
To prevent the ethyl alcohol in a cosmetic from being
diverted illegally for use as an alcoholic beverage,
it may be "denatured." This means that it contains an
added "denaturant" that makes it undrinkable.
Denatured ethyl alcohol may appear in the ingredient
listing under several different names. You may see
the abbreviation SD Alcohol (which stands for "specially
denatured alcohol"), followed by a number or a number-letter
combination that indicates how the alcohol was denatured,
according to the formulary of the United States Bureau of
Alcohol, Tobacco, and Firearms (BATF). Among the specially
denatured alcohols acceptable for use in various cosmetics
are SD Alcohol 23-A, SD Alcohol 40, and SD Alcohol 40-B.
The term "Alcohol Denat." was introduced in Europe as a
generic term for denatured alcohol in the interest of
harmonizing ingredient names internationally. It
frequently appears on products that are marketed both
in the U.S. and abroad. You also may see a dual
declaration, such as "SD Alcohol-40 (Alcohol Denat.)."
