Invisible 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 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.

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 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.

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.

An amino acid-derived chelating agent that stabilizes formulas by binding trace metals. Published assessments support its use at cosmetic concentrations.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

Benzyl salicylate is a fragrance fixative that also absorbs some UV light. It is on the EU allergen disclosure list, but the evidence suggests it sensitizes fewer people than most other listed fragrance allergens.

A sweet, hay-like fragrance ingredient naturally found in tonka bean and lavender. It is one of the 26 EU-designated fragrance allergens and is also subject to an EU maximum concentration limit in finished cosmetic products.

A spicy, clove-derived fragrance and flavor compound. It is one of the 26 EU-designated fragrance allergens because it can trigger contact allergy in sensitized individuals, though CIR review found it safe as typically used in cosmetics.

A floral, rose-like fragrance compound found in many essential oils. It is one of the 26 EU-designated fragrance allergens, meaning a documented minority of people can develop contact sensitization, so brands must disclose it above set thresholds.

Hydroxycitronellal is a lily-of-the-valley scented fragrance ingredient on the EU allergen disclosure list. It has well-documented sensitizing potential in patch-test studies, so it is worth checking the label if you have known fragrance sensitivities.

Isoeugenol is a clove-scented fragrance compound and is considered one of the more potent sensitizers among the EU-listed fragrance allergens. It is disclosed on labels so people with a known allergy can avoid it.

A citrus-scented fragrance component. Fine for most, but it oxidizes over time into a known contact allergen, so it must be labelled in the EU.
