Hydrating Cream-to-Foam Cleanser

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

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

A gentle amino acid-based surfactant derived from coconut oil, used as a primary cleanser in many sulfate-free shampoos and body washes. It is well tolerated and designed to reduce irritation common to harsher sulfonated surfactants.

A coconut-derived, mild foam-boosting surfactant closely related to cocamidopropyl betaine. It is generally well tolerated in rinse-off products but, like its chemical cousin, can occasionally cause contact irritation on already-compromised or very reactive skin.

A coconut-derived mild surfactant best known as the main cleansing agent in syndet ("soap-free") bars and gentle body washes. It has a good tolerability record and is often chosen specifically for sensitive or eczema-prone skin.

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.

A PEG-based emulsifier that blends oils and water in formulas. It is a workhorse ingredient in stable emulsions and is approved for cosmetic use. Well tolerated.

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

A triterpenoid from Centella asiatica with published research linking it to skin barrier function and calming effects. It appears well tolerated at cosmetic levels.

A lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

One of the three major ceramides naturally found in human skin. Ceramide AP plays a critical role in maintaining the skin barrier and is extensively studied as a safe, essential ingredient. It is derived synthetically or from plant sources.

Carbomer is a synthetic polymer used purely to thicken and stabilize gels and lotions, with negligible skin penetration due to its large molecular size. Safety reviews have found low toxicity and minimal irritation potential even in leave-on use.

A wax-like ester of ethylene glycol and stearic acid used purely to thicken shampoo/conditioner and give it a pearly opaque look; it has no cleansing or active role. CIR found it non-sensitizing and non-irritating even at high test concentrations, and decades of manufacturer exposure data show no reported health effects.

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

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 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 strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

A beta hydroxy acid used to smooth texture and clear pores. Safe at cosmetic levels; can be mildly irritating if overused.

Sodium PCA is a natural component of skin's own moisturizing factor and is used in cosmetics as a humectant to help skin hold onto water. It has an extensive history of safe use with no meaningful irritation or sensitization signal.

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 humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A waxy sterol found naturally in skin and used in cosmetics as an emollient and emulsifier. It supports the skin barrier and is well tolerated across skin types.

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

A mild non-ionic cleansing agent made from coconut fatty alcohols and plant sugars (glucose). It is widely used in sulfate-free shampoos and gentle cleansers and is one of the least irritating surfactants in common use.

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.

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.

A rheology modifier that thickens gels and serums while maintaining a lightweight, non-sticky feel. Provides suspension and stability in water-based formulas. Widely used and well tolerated.

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.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

A synthetic surfactant widely used to emulsify oils and water in cosmetics. It is well tolerated and has been used safely in cosmetic formulations for decades.

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 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.
