Lanolin is a waxy substance secreted by the sebaceous glands of wool-bearing animals (sheep). It is extracted from raw wool during washing and consists of complex mixtures of esters, diesters, and hydroxy esters of fatty acids and alcohols. It is highly occlusive and closely mimics human sebum.
Octyldodecanol is a long-chain branched fatty alcohol used as an emollient, viscosity modifier, and solvent in cosmetics. It is a liquid wax ester precursor that imparts a soft, non-greasy feel.
Lanolin: Lanolin is broadly safe for cosmetic use. It is FDA-approved as a skin protectant in OTC products. The primary concern is contact allergy: approximately 1–2% of the general population and up to 5–8% of eczema patients are sensitized to lanolin alcohols (the allergen fraction). Purified lanolin and lanolin alcohols in modern formulations have lower allergenicity than historical crude grades. Lanolin is not a carcinogen, hormone disruptor, or systemic toxin. It is not vegan.
Octyldodecanol: Octyldodecanol is considered safe at cosmetic use levels. No carcinogenic, mutagenic, or endocrine-disrupting effects are documented. It is a common ingredient in luxury and color cosmetics with a well-established safety record. It is non-irritating and non-sensitizing.
