Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Isopropyl Alcohol is a small, fast-evaporating alcohol.
Formulators use it as a solvent, a way to think out thick liquids, an antifoaming agent, and occasionally a fragrance ingredient.
Reported use concentrations run from 0.002%-100% and any number over 50% usually comes from a nail product.
Actual skincare numbers run much lower: cleansers (0.3-26%), toners (0.07-7%), face moisturizers (0.04-0.2%).
The Cosmetic Ingredient Review Expert Panel reviewed it and concluded it is safe in the present practices of use and the International Agency for Research on Cancer classifies it as a non-carcinogenic to humans.
True allergy to this ingredient is uncommon but real: 44 out of 1,450 patients patch tested between 1992-2011 reacted with most cases clustering in people with leg ulcers, occupational hand eczema, or repeated use of Isopropyl Alcohol on already-broken skin.
Irritation and dryness are far more likely than allergy; before you throw away your skincare, just know this is dose-dependent and the risk is modest.
The irritant potential of the alcohols used in hand antiseptics is very low and skin irritation is significantly lower after alcohol application than after detergents (though isopropanol is somewhat more irritating than ethanol).
A 70% solution was a severe eye irritant in rabbit eye tests so the industry keeps this ingredient at low percentages in eye-area products.
One genuine caution: a 70% solution was a severe eye irritant in rabbit eye tests, so it belongs at low percentages in eye-area products, which is where the industry already keeps it.
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.
Learn more about Isopropyl AlcoholPropylene Glycol is a synthetic, colorless, odorless liquid that has been a staple in cosmetics for decades. It is a skin conditioning agent, humectant, and solvent.
As a humectant, it draw water to the skin to reduce flaking and restore suppleness. It's also a solvent that helps dissolve other actives and keeps formulas stable across temperature changes.
The CIR Expert Panel has confirmed this ingredient to be nontoxic and clinical studies show no sensitization at cosmetic use concentrations.
True allergic reactions are quite rare: a 15-year retrospective study of 6,751 patients found only 0.31% had a positive reaction (and less than half were considered clinically relevant).
It seemed that when sensitization does occur, it's most commonly linked to topical medication (like corticosteroids) and not cosmetics. Allergic contact dermatitis also appears largely limited to individuals with underlying skin conditions.
Overall, propylene glycol is a well-studied ingredient that most people can tolerate without issue.
