CIR Safety Assessment of Alpha Hydroxy Acids as Used in Cosmetics: The CIR Expert Panel reviewed glycolic acid as part of its alpha hydroxy acid assessment. It is safe as used in cosmetics as an exfoliant and pH adjuster. At active exfoliant concentrations the Panel recommended sun protection advisories due to increased photosensitivity. Stinging or irritation may occur, especially in sensitive skin.

CTPA Ingredient Library — Glycolic Acid: CTPA lists glycolic acid as a permitted alpha hydroxy acid in cosmetics. At active concentrations, EU Cosmetics Regulation requires advisory labelling on increased sun sensitivity. At low concentrations it functions as a pH adjuster and is considered safe.

CIR Safety Assessment of Alpha Hydroxy Acids as Used in Cosmetics: The CIR Expert Panel reviewed lactic acid as part of its AHA assessment. It is safe as a pH adjuster and gentle exfoliant. At active exfoliant concentrations, the Panel recommended sun protection advisories due to increased photosensitivity potential.

CTPA Ingredient Library — Lactic Acid: CTPA lists lactic acid as a safe alpha hydroxy acid used as a pH adjuster and skin-conditioning agent. At higher active concentrations, CTPA advises labelling for potential increased sun sensitivity, consistent with EU Cosmetics Regulation requirements for AHA products.

CIR Safety Assessment of Alpha Hydroxy Acids as Used in Cosmetics: The CIR Expert Panel reviewed citric acid as part of its assessment of alpha hydroxy acids. It is safe at concentrations used as a pH adjuster. At higher active exfoliant concentrations, the Panel recommended consumer advisories on increased photosensitivity.

CTPA Ingredient Library — Citric Acid: CTPA lists citric acid as a safe, permitted cosmetic ingredient functioning as a pH adjuster. At higher concentrations where it acts as an active AHA exfoliant, CTPA advises appropriate labelling regarding potential skin sensitivity.

Niacinamide (Vitamin B3) — FDA Cosmetic Ingredient Review: Niacinamide is considered safe for use in cosmetics. It is a well-established skin-conditioning agent with evidence supporting its role in improving skin texture, tone, and barrier function.

CTPA Ingredient Library — Niacinamide: CTPA lists niacinamide as a safe and effective skin-conditioning agent widely used across cosmetic formulations, with a strong safety profile across concentrations typically used in cosmetics (2–10%).

FDA GRAS Database — Glycerin: Glycerin (glycerol) is affirmed as Generally Recognized As Safe (GRAS) by the FDA. As a cosmetic ingredient, it is one of the most widely used and well-tolerated humectants, drawing moisture from the environment to the outer layers of the skin.

FDA Briefing on Hyaluronic Acid in Topical Formulations: Sodium hyaluronate is generally recognized as safe (GRAS) as a cosmetic ingredient. It functions as an effective humectant and skin-conditioning agent suitable for all skin types.

FDA OTC Skin Protectant Active Ingredient — Allantoin: The FDA recognises allantoin as a safe and effective OTC skin protectant active ingredient at concentrations of 0.5–2.0%. It soothes and protects irritated skin and helps relieve minor skin irritation from chapping, chafing, and wind.

CTPA Ingredient Library — Allantoin: CTPA lists allantoin as a safe, soothing skin-conditioning agent with a long history of safe use as a skin protectant. It is well tolerated by sensitive and reactive skin types.

CIR Safety Assessment of Panthenol as Used in Cosmetics: The CIR Expert Panel found panthenol (provitamin B5) safe as used in cosmetic formulations. It functions as a humectant and skin-conditioning agent, improving skin hydration and supporting barrier function, with no significant irritation or sensitisation concerns.

CTPA Ingredient Library — Panthenol: CTPA lists panthenol as a safe humectant and skin-conditioning agent. As provitamin B5, it supports healthy skin cell metabolism. It is well tolerated and considered safe for sensitive skin.

FDA — Phenoxyethanol in Cosmetics: FDA has reviewed phenoxyethanol as a cosmetic preservative and considers it safe at concentrations up to 1.0% in cosmetic products. FDA advises caution in products used around the mouth of infants.

CTPA Ingredient Library — Phenoxyethanol: CTPA confirms phenoxyethanol is a permitted cosmetic preservative under EU Cosmetics Regulation at a maximum concentration of 1.0%, and is considered safe for use in both rinse-off and leave-on products.

CIR Safety Assessment of Ethylhexylglycerin as Used in Cosmetics: The CIR Expert Panel found ethylhexylglycerin safe as used in cosmetics. It functions as a skin-conditioning agent and preservative booster enhancing the efficacy of other preservatives. No significant irritation or sensitisation was identified at cosmetic concentrations.

CTPA Ingredient Library — Ethylhexylglycerin: CTPA lists ethylhexylglycerin as a safe skin-conditioning agent and preservative enhancer. It is used in cosmetics to improve formula feel and boost preservation systems, and is considered non-irritating for most skin types.
