Clinical Protection Cotton Fresh

An aluminum-zirconium complex used in antiperspirants to reduce sweat. Regulatory bodies have found no credible evidence linking cosmetic aluminum salt antiperspirants to breast cancer or Alzheimer disease.

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

A highly refined, inert petroleum-derived emollient that has been used in cosmetics and skincare for over a century. It creates a protective moisture barrier on the skin and is well tolerated by the vast majority of users, with minimal risk of irritation or sensitization.

A refined cellulose derivative processed from plant sources, used as a thickener and texturizing agent in cosmetics. It is an inert polysaccharide with no known sensitization or irritation potential and is widely used in personal care and pharmaceutical formulations.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

A mineral thickener and anti-caking agent widely used in sunscreens and cosmetics to control texture and prevent ingredient separation. CIR has reviewed silica in cosmetic use and found no basis for concern at the levels used topically.

A lightweight, odorless emollient made by combining coconut or palm-derived fatty acids with glycerin. It spreads easily, feels non-greasy, and has a long history of use in skin and hair products with no meaningful irritation or sensitization signal.

A crosslinked silicone polymer that creates a velvety texture in primers and powders. The crosslinked structure does not change its safety profile, and it is inert and well tolerated.

A starch derivative used in cosmetics to thicken formulations and improve texture. It has been used safely in food and cosmetics for decades and shows low irritation potential across rinse-off and leave-on products.

A plant-based thickener derived from cellulose that creates smooth, gel-like textures in formulas. One of the most studied and best-tolerated thickeners in cosmetics, used in shampoos, face masks, and leave-on products for decades.

A small-dose synthetic antioxidant that prevents oils and fragrance in a formula from oxidizing. Not shown to pose a toxicological risk at the levels used in cosmetics.
