Guava Protect & Repair Shampoo

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

A mild amino acid-derived surfactant combining oleic acid and taurine. Used in gentle facial and body cleansers for its low irritation profile and effective cleansing.

A sugar-derived, biodegradable cleansing surfactant made from coconut/palm fatty alcohol and glucose; it is markedly gentler than sulfates and is the workhorse of "sensitive skin" or fragrance-free cleansers. CIR reviewed it with other alkyl glucosides and found it safe as used when the finished product is formulated to be non-irritating.

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.

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

A polymer of quaternary ammonium compounds widely used as a conditioning and antistatic agent in hair products. It is well established in cosmetic formulations with a strong safety record in rinse-off applications.

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 soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A gentle humectant derived from glucose. It draws water to the skin and is mild enough for sensitive skin types. Widely used in cosmetics without reported safety concerns.

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