Unscented Smooth Solid Deodorant

An ester emollient used to soften and condition skin. The 2017 CIR safety assessment found it non-irritating and non-sensitizing across 415 surveyed formulas at concentrations from 1 to 33 percent.

A synthetic emollient made from stearyl alcohol and propylene oxide, used to give antiperspirant roll-ons and creams a light, non-greasy glide. Data are thinner than for older emollients, but what exists shows good tolerance, and CIR reviews of related PPG ethers found them safe as used.

Natural corn starch used to absorb excess oil and add body to cosmetic formulas. It is very well-tolerated and has a long history of safe use in personal care.

A naturally derived fossil wax used to provide texture and moisture retention in cosmetics. Long history of use with no documented safety concerns in standard formulations.

A fatty alcohol derived from stearic acid that thickens creams and gives them a smooth, non-greasy glide. It is one of the fatty alcohols the CIR panel reviewed together and found safe as used, with a very low reported rate of contact sensitization.

A lightweight hydrocarbon that gives formulas a smooth, silky feel. Used in color cosmetics and sunscreens. Well tolerated and inert.

A five-carbon alcohol used as a humectant to draw moisture into the skin and help formulations remain stable. It is well tolerated in the concentrations used in cosmetics.

An ester combining lauryl alcohol and lactic acid, used as an emollient and conditioner in cosmetics. Sparse published data but consistent use without documented adverse effects.

Mandelic acid is a larger-molecule alpha hydroxy acid that tends to penetrate skin more slowly than glycolic acid, which is generally associated with less stinging and redness. It carries the same general AHA cautions around sun sensitivity but is often better tolerated by reactive skin.

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

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 soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A natural alkaloid and studied active ingredient in skincare, valued for its antioxidant properties and potential to promote local circulation and reduce puffiness. Topical application results in minimal systemic absorption, graded low concern in regulatory assessments.

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.
