Moisturizing Rinse Out Conditioner

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

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

A cationic conditioning agent used in rinse-off products like shampoos and conditioners to provide softness and detangling. Generally well tolerated but can cause irritation at high concentrations in some individuals.

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 rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A monounsaturated fatty acid found naturally in plant and animal oils, used as an emollient and emulsifier in skincare products. Oleic acid is well tolerated by most people and supports skin barrier function, though those with oleic acid sensitivity should avoid or patch test first.

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

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

A naturally occurring acid used to preserve and adjust pH in cosmetic formulas. It is generally recognized as safe at cosmetic use levels, with mild irritation possible on broken or very sensitive skin at higher concentrations.

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.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

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

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.

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 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.

A jasmine-like fragrance compound frequently used in soaps and lotions. It is one of the 26 EU-designated fragrance allergens, though studies suggest its sensitization potency is comparatively low relative to other listed allergens.

Butylphenyl methylpropional, widely sold under the trade name Lilial, was banned from cosmetics in the EU starting March 2022 after being classified as toxic to reproduction based on animal studies. Products made and sold in the EU after that date should no longer contain it.

A floral fragrance component and one of the EU-labelled fragrance allergens. Usually fine, worth watching if you react to scented products.

An FDA-approved synthetic colorant commonly used in cosmetics and personal care products. A small proportion of individuals report sensitivity or allergic reactions, particularly those with existing dye sensitivities. Remains safe at approved cosmetic concentrations.
