Conditioner Repair Argan Oil

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

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 long-chain quaternary ammonium compound used in rinse-off conditioners and leave-on styling products for conditioning and static control. It is well documented in cosmetic use with a strong safety record.

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

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 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 common preservative and fragrance/solvent ingredient found naturally in many essential oils. It is well tolerated by most people at the levels used in cosmetics, but it is one of the 26 EU-designated fragrance allergens and can trigger reactions in people with an existing sensitivity.

A fast-evaporating solvent used to carry actives and create a light, quick-drying texture in toners and washes. At the concentrations used in rinse-off and brief-contact formulas, it has a well-established safety record, though repeated contact with high-concentration formulas can be drying.

A fatty-acid and tocopherol-rich plant oil used as a hair and skin emollient; CIR's review of plant-derived fatty acid oils found no evidence of irritation or sensitization and a long history of safe use in food and cosmetics.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.

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 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.

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

An amino acid used in skincare formulas to hydrate and condition the skin. Amino acids are well-tolerated at cosmetic use levels and have a long history of safe use.
