Linoleic acid (CAS 60-33-3) is an essential omega-6 fatty acid widely used in nutraceuticals, cosmetics, and as a precursor for industrial polyunsaturated fatty acid derivatives. It also serves as a raw material for paints, protective coatings and coating driers, and for making soaps, emulsifiers and surfactants. It is a key component in skincare formulations for its moisturizing and anti-inflammatory properties, and in dietary supplements for cardiovascular and metabolic health support. This product contains **≥95% linoleic acid** (CH₃(CH₂)₄CH=CHCH₂CH=CH(CH₂)₇CO₂H), with a molecular weight of **280.45 g/mol**. Store at **2–8°C** in a sealed container under inert gas to prevent oxidation. No signal word applies, as it is non-hazardous under normal handling conditions. Molekula supplies linoleic acid 95% min from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
