What’s inside

WaterGenerally safe

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

Sodium Lauroyl Methyl IsethionateGenerally safe

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.

Full ingredient details →
Cocamidopropyl BetaineWatch if sensitive

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.

Full ingredient details →
Acrylates CopolymerGenerally safe

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.

Full ingredient details →
Glyceryl StearateGenerally safe

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

Full ingredient details →
GlycerinGenerally safe

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

Full ingredient details →
Olive Fruit OilGenerally safe

Cold-pressed oil from olive fruit, valued as a carrier and emollient in skincare formulas. Well tolerated across skin types and delivers fatty acids that support skin barrier integrity.

Full ingredient details →
ChamomileWatch if sensitive

Chamomile extract is used for its soothing and mild antioxidant reputation and is generally well tolerated. It belongs to the Asteraceae (Compositae) plant family, so people with a known ragweed or daisy-family allergy occasionally react to it and may want to patch test first.

Full ingredient details →
Ginkgo Biloba Leaf ExtractGenerally safe

A plant extract valued for antioxidant and skin-conditioning properties, used in skincare formulations to support skin health. It has been used traditionally and in modern cosmetics with a reasonable safety history. Rarely, plant extracts can trigger sensitivities in individuals with tree pollen allergies.

Full ingredient details →
Hydroxypropyl GuarGenerally safe

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.

Full ingredient details →
Xanthan GumGenerally safe

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.

Full ingredient details →
Citrus Aurantium Dulcis (Orange) OilWatch if sensitive

A cold-pressed oil from sweet orange peel with a bright, citrus scent, containing furanocoumarins that can cause phototoxic reactions (pigmentation and irritation) when exposed to sunlight. This oil is best reserved for rinse-off products or formulations where sun exposure is unlikely or protected, as it can trigger adverse reactions in reactive individuals on sun-exposed skin.

Full ingredient details →
Citrus Paradisi (Grapefruit) Peel OilWatch if sensitive

An essential oil from grapefruit peel rich in limonene and other furocoumarins. It is a fragrance allergen that carries phototoxicity risk, particularly in sun-exposed areas; some formulations concentrate enough to cause phototoxic reactions in sensitive individuals.

Full ingredient details →
Mentha Piperita (Peppermint) OilWatch if sensitive

An essential oil rich in menthol and other terpenes. It adds a cooling, fresh note to products but is a known skin irritant and contact allergen, especially in leave-on products or for people with sensitive or inflamed skin. The oil oxidizes over time, increasing allergenicity.

Full ingredient details →
Lactic AcidWatch if sensitive

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.

Full ingredient details →
Tetrasodium Glutamate DiacetateGenerally safe

An amino acid-derived chelating agent that stabilizes formulas by binding trace metals. Published assessments support its use at cosmetic concentrations.

Full ingredient details →
PhenoxyethanolCommonly feared, low concern

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

Full ingredient details →
HydroxyacetophenoneGenerally safe

A preservative and antioxidant that helps prevent microbial growth and oxidative degradation in formulas. Published assessments support its use at cosmetic levels.

Full ingredient details →
Citric AcidGenerally safe

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

Full ingredient details →
Sodium HydroxideGenerally safe

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.
