Description

Acetylated Lanolin Alcohol CAS NO 61788-49-6 is a chemically modified derivative of lanolin, known for its enhanced stability and hydrophobic properties. This modification is critical for applications requiring a non-greasy, highly occlusive, and oxidation-resistant emollient. It is an essential ingredient for formulators in the personal care, cosmetic, and pharmaceutical industries seeking to improve product texture, skin barrier protection, and shelf life.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, lipsticks, and sunscreens, providing a smooth, non-greasy feel and enhanced water resistance.
• Hair Care Products: Used in conditioners, hair masks, and styling products to impart shine, reduce frizz, and improve manageability without heavy buildup.
• Pharmaceutical Topicals: Serves as a base or excipient in ointments, pastes, and medicated creams, offering excellent occlusive properties to promote skin hydration and active ingredient delivery.
• Color Cosmetics: Improves the pigment dispersion, texture, and long-wear properties of foundations, eyeshadows, and mascaras.
• Baby Care Products: A key ingredient in diaper rash creams and baby lotions for its gentle, protective, and soothing characteristics on sensitive skin.
• Industrial Emollients & Lubricants: Employed in specialty lubricants, leather conditioners, and textile softeners where a stable, hydrophobic lipid is required.

Quality Control

Our Acetylated Lanolin Alcohol is produced and tested to meet stringent quality standards suitable for cosmetic and pharmaceutical applications. Each batch is analyzed for key parameters including acid value, saponification value, hydroxyl value, and melting point to ensure consistency and performance. Certificates of Analysis (COA) are available upon request, and our quality system supports compliance with relevant guidelines including ISO 9001 and cGMP where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
