This versatile oil is colorless and odorless, offering a unique combination of high lubricity and enhanced softening effects, making it ideal for a range of applications. It is extensively used as an effective skin conditioner, protectant, lubricator, and emollient across various skincare and personal care products, including skin care, anti-aging treatments, sun care, lip care, hair care, baby care, nail care, and aromatherapy, due to its light texture and safe profile for dermal applications.

How does the high content of Oleic Acid benefit the skin?
