Mandarin Orange Hand Soap

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

A common foaming cleanser, milder than SLS. Fine for most people in a rinse-off product.

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 coconut-derived fatty acid amide used as a foam booster and thickener in shampoos and washes. It is a recognized, if uncommon, contact sensitizer, and because it belongs to the same ethanolamine family reviewed alongside cocamide DEA, formulators are advised to keep it free of nitrosamine-forming contaminants; well-made products with controlled impurity levels are considered acceptable for rinse-off use.

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.

A preservative that works by slowly releasing small amounts of formaldehyde to control microbial growth. This makes it an effective preservative, but people with a known formaldehyde or fragrance-type sensitivity may develop irritation or an allergic reaction, especially with prolonged use of leave-on products.

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

A polyethylene glycol ether of lauryl alcohol, used as a mild surfactant and emulsifier in cleansers and other rinse-off products. CIR assessments support the safety of laureth surfactants in cosmetics, and they are often chosen for their mildness.

Tetrasodium EDTA is a chelating agent that binds trace metal ions to keep formulas stable and help preservatives work better. It has circulated online as a supposed "toxic" additive, but decades of safety review support its use at cosmetic concentrations.

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.

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

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 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.
