Scalp Clarifying Shampoo, Fragrance Free

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

A sulfate-free, amino acid-derived surfactant with a mild profile often used in gentle body washes and shampoos. It is well tolerated and formulated to provide effective cleansing with reduced risk of irritation compared to traditional sulfate surfactants.

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

A synthetic polymer used to thicken and stabilize cosmetic formulas. The polymer chains are too large to penetrate skin; graded safe by the Cosmetic Ingredient Review and widely used in rinse-off and leave-on products.

A naturally occurring dipeptide with antioxidant properties, studied for skin health and barrier function support. It is widely used in skincare and cosmetic formulations with a strong safety history. No known contact allergens or sensitization reactions have been documented.

A mixture of lightweight hydrocarbons derived from mineral oil or plants. It is biologically inert, non-irritating, and widely used in moisturizers and primers to improve texture without leaving residue.

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 buffering agent used in small amounts to maintain or adjust the pH of formulas to keep them skin-friendly. It is not added as an active ingredient but to keep the product at a safe and stable pH level.

A modified guar gum used to thicken and stabilize emulsions and gels. It is derived from guar beans and is well tolerated when applied topically. It is common in skincare formulas where a smooth texture is valued.

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.

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

Bisabolol is a botanically derived (or synthetically nature-identical) compound used for its calming, anti-irritant reputation in sensitive-skin formulas. Safety reviews and long clinical use have found it well tolerated with a low rate of reported reactions.

A biodegradable chelating agent that binds trace metals to stabilize formulas, often chosen as a gentler alternative to EDTA. It is readily degraded in the environment and poses minimal toxicity concerns at cosmetic concentrations.

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

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

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.

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.
