48H Mineral Deodorant Optimal Tolerance Roll-On

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

A small humectant and solvent molecule that helps other ingredients dissolve and helps skin hold water. It is one of the most studied cosmetic ingredients and is considered safe at the concentrations used in personal care products.

A polypropylene glycol-based surfactant and emulsifier used to stabilize cosmetic formulas. Safety assessments indicate it is well-tolerated when used at typical cosmetic concentrations.

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 polyethylene glycol ester of hydrogenated castor oil, widely used as an emulsifier and solvent in rinse-off and leave-on cosmetics. PEG-modified ingredients are graded as safe in cosmetics by the CIR when formulated at typical use levels.

A readily bioavailable form of zinc used in skincare formulations for its mineral content and regulatory support. It is well tolerated and commonly used in cosmetics without sensitization or irritation concerns at cosmetic concentrations.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

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

Ordinary salt, used in surfactant-based products like shampoos and body washes to adjust viscosity by interacting with the surfactant micelles. It has no meaningful toxicity concern at cosmetic use levels; the main practical downside is that too much can make a formula feel less mild.
