Caprylic/Capric Triglyceride vs Lanolin: which is worse?

What is Caprylic/Capric Triglyceride?

Caprylic/capric triglyceride (CCT) is a mixture of medium-chain triglycerides (caprylic acid C8 and capric acid C10) derived from coconut oil or palm kernel oil. It is a light, odorless, dry-feeling emollient and carrier oil widely considered one of the most versatile cosmetic ingredients.

What is Lanolin?

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.

Documented risks

Caprylic/Capric Triglyceride: Caprylic/capric triglyceride is one of the safest cosmetic ingredients with essentially no known safety concerns. The CIR has reviewed medium-chain triglycerides and confirmed their safety. It does not clog pores (comedogenicity rating 1–2/5), is suitable for all skin types including acne-prone, and is used in the most sensitive formulations. No carcinogenic, mutagenic, or endocrine-disrupting effects are known. It is suitable for vegan formulations (plant-derived).

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.
