Description

Spermaceti CAS NO 8002-23-1 is a natural wax derived from the head cavity of the sperm whale, though modern commercial supplies are typically synthetic or derived from other botanical sources. This unique material is valued for its exceptional emollient properties, stability, and ability to form elegant, non-greasy textures. It serves as a critical functional ingredient for formulators in the cosmetics, pharmaceutical, and high-end lubricant industries seeking superior performance and skin feel.

Application

• Cosmetics & Personal Care: A key emollient and texture enhancer in high-quality creams, lotions, lipsticks, and ointments, providing a smooth, non-greasy finish and excellent spreadability.
• Pharmaceuticals: Used as a base or stiffening agent in the formulation of topical creams, suppositories, and controlled-release drug delivery systems.
• Candlemaking: Historically prized for producing high-quality, clean-burning candles with a bright flame and minimal smoke.
• Lubricants & Polishes: Employed in specialized lubricants, leather conditioners, and fine furniture polishes where a protective, non-tacky film is required.
• Textile & Fiber Treatment: Acts as a softening agent and lubricant for fibers and threads in textile manufacturing.
