Oil-Free Acne Wash

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

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

A primary cleansing surfactant similar in strength to sodium laureth sulfate, used in many "sulfate-lite" shampoos even though it is itself a sulfonate detergent. CIR concluded it is safe in rinse-off products; it can be drying or irritating for already-sensitized scalps at higher use levels, same as most anionic surfactants.

A coconut-derived amphoteric surfactant used to boost foam and mildness in cleansers and shampoos. CIR has reviewed it as safe as used, but it is one of the more established contact-allergy triggers in personal care, usually traced to manufacturing impurities such as amidoamine and dimethylaminopropylamine (DMAPA) rather than the betaine itself. People with a history of eyelid or scalp dermatitis are more likely to react.

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 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.

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 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 plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

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.

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