Fructis Nourishing Treat Shampoo

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

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 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.

A rich, solid-at-room-temperature oil that deeply softens dry skin and hair. It is well tolerated overall, but its high lauric acid content is considered comedogenic by many dermatologists, so it can trigger breakouts in people who are acne-prone.

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

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 phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A citrus-scented fragrance component. Fine for most, but it oxidizes over time into a known contact allergen, so it must be labelled in the EU.

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 widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

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

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.

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 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 strong foaming cleanser. It can be drying or irritating for some people, especially in leave-on or high-concentration products. It is not a toxin, and it rinses away.

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

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

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.
