Repairing Conditioner

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

A lightweight ester emollient with good skin compatibility. The CIR Expert Panel assessed isoamyl laurate as safe in cosmetic use when formulated to be non-irritating, with typical concentrations at or below 2 percent.

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

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 plant-derived emollient oil rich in ricinoleic acid, used in skincare for decades. Contact allergy has been reported but is uncommon relative to how widely it is used in leave-on products.

A wax ester derived from jojoba oil that closely resembles the skin's own sebum esters, used to soften and smooth skin. Available safety data has not flagged meaningful irritation or sensitization risk at cosmetic use levels.

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 positively charged conditioning polymer used in shampoos and conditioners to reduce frizz and improve manageability. It is well tolerated and has been safely used in cosmetics for decades.

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

A plant-derived emulsifier made from glycerin, glucose, and stearic acid that helps blend oil and water phases. It is graded low concern in published cosmetic ingredient assessments and is well tolerated in both rinse-off and leave-on formulas.

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.

Technically a liquid wax ester rather than a true oil, jojoba closely resembles skin's own sebum and absorbs without feeling greasy. It is well tolerated across skin types, including acne-prone skin, with no significant irritation or comedogenicity signal in the available data.

Chlorphenesin is a preservative subject to an EU maximum concentration limit and has been linked to contact dermatitis in a minority of users, particularly with repeated exposure. Most people tolerate it at the regulated use level without issue.

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.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

A humectant derived from glycerin, used to attract and retain moisture in cosmetic formulas. Evidence from cosmetic use indicates it is well-tolerated and produces minimal sensitization even on sensitive skin.

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