Dermo Sensitive 24H Anti-Perspirant Roll-On

The base most products are built on. It carries the other ingredients and has no safety concern.

An aluminum salt used in antiperspirants to temporarily plug sweat ducts and reduce underarm wetness. Regulatory safety reviews have not found credible evidence linking its cosmetic use to breast cancer or Alzheimer disease.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

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.

A gentle surfactant derived from stearyl alcohol and ethylene oxide. It is used to stabilize emulsions and is well tolerated in rinse-off and leave-on formulas. Approved for cosmetic use.

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 surfactant derived from stearyl alcohol with a higher degree of ethoxylation than Steareth-2, providing enhanced emulsification. It is graded safe for cosmetic use and well tolerated.

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

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A mineral powder valued for its absorbent and soft-feel properties in cosmetics. Cosmetic-grade talc is required to be asbestos-free; inhalation risk from topical application is minimal. Generally well tolerated when used as intended.

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.
