Description

Octyl 12-Hydroxystearate is a high-performance ester derived from 12-hydroxystearic acid and 2-ethylhexanol (octyl alcohol). This compound serves as a versatile and effective emollient, lubricant, and viscosity modifier in demanding formulations. It is particularly valued in the personal care, cosmetics, and specialty lubricants industries for its excellent skin feel, stability, and compatibility with a wide range of ingredients.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, lipsticks, and sunscreens, providing a non-greasy, silky feel.
• Hair Care Products: Used in conditioners, hair serums, and styling products to impart shine, reduce frizz, and improve combability.
• Pharmaceutical Topicals: Serves as a base or excipient in ointments, creams, and dermatological preparations due to its skin compatibility and stabilizing properties.
• Specialty Lubricants & Greases: Functions as a synthetic ester base or additive in high-performance lubricants, offering good low-temperature properties and oxidation stability.
• Plasticizers & Polymer Additives: Employed as a secondary plasticizer or lubricant in PVC and other polymer processing to enhance flexibility and processing characteristics.
• Industrial Coatings & Inks: Used as a flow and leveling agent or lubricant in specialty coating systems to improve surface finish and performance.
