THE STORY OF OLEIC ACID
Oleic Acid: The Skin-Softening Fatty Acid for Rich, Nourishing Formulations
Oleic Acid is a monounsaturated fatty acid (C18:1) widely used in skincare, haircare, and personal-care formulations.
Known for its deep-conditioning, penetration-enhancing, and emollient properties, it helps soften the skin and improve the texture of emulsions.
Common in creams, lotions, soaps, serums, hair oils, and emulsifier production.
Derived from Natural Vegetable Oils Through Hydrolysis & Purification
Oleic Acid is obtained from vegetable oils rich in monounsaturated fats, such as:
• Olive Oil
• Sunflower Oil
• Palm Oil
• Avocado Oil
It is produced by hydrolysis of triglycerides, followed by fractional distillation to yield a high-purity, cosmetic-grade fatty acid.
TRCkem provides Oleic Acid with various purity grades suitable for cosmetic and industrial applications.
