KP Bump Eraser Body Scrub 10% AHA

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

The smallest and most penetrating alpha hydroxy acid, used to loosen the bonds between dead skin cells for smoother texture and tone. It is a genuine irritant at higher concentrations or low pH, can increase sun sensitivity, and the EU restricts free acid content and requires sunscreen-use wording on labeling.

A coconut-derived mild surfactant best known as the main cleansing agent in syndet ("soap-free") bars and gentle body washes. It has a good tolerability record and is often chosen specifically for sensitive or eczema-prone skin.

A larger, gentler alpha hydroxy acid than glycolic acid, used to exfoliate and to draw in moisture. It can still cause stinging or increased sun sensitivity at higher concentrations, so daytime SPF use is sensible, but it is generally better tolerated than glycolic acid.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

A naturally occurring fatty acid (also made in the body and found in many foods) used to thicken lotions and help stabilize cleansing bars. It is one of the most well-studied emollient ingredients and is not a meaningful irritant at cosmetic use levels.

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

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 saturated fatty acid found in palm oil and naturally in the skin, used as an emollient to soften and condition skin. It is one of the most studied fatty acids and is well tolerated.

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

A humectant sugar alcohol that draws water into the skin. It is well tolerated and widely used in skincare and food. Not known to cause concern at the concentrations used in cosmetics.

Finely milled oat that the FDA recognizes as an over-the-counter skin protectant for temporary relief of minor itching and dryness. Well tolerated, including on eczema-prone skin, with rare contact allergy in people with pre-existing oat or cereal sensitivity.

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

Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.

A soothing plant extract traditionally used in skincare, valued for its potential anti-inflammatory properties. Published assessments note it is generally well tolerated in cosmetic formulations, though people with sensitivities to botanicals may want to patch test.

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.

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.

A surfactant derived from stearyl alcohol with a higher degree of ethoxylation than Steareth-2, providing enhanced emulsification. It is graded safe for cosmetic use and well tolerated.

A saturated fatty acid used as an emollient and texture ingredient in creams and formulations. It is well tolerated and commonly used at safe concentrations.

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

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.

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.

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.
