Description

Glyceryl Sorbitan Oleostearate is a non-ionic surfactant and emulsifier derived from natural fatty acids and polyols. This versatile compound is valued for its ability to stabilize complex mixtures, particularly in formulations requiring a smooth texture and consistent performance. It is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable, multifunctional ingredients for emulsions and topical products.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Stabilizing agent for water-in-oil (W/O) and oil-in-water (O/W) emulsion systems.
• Key ingredient in sunscreen formulations for texture enhancement and stability.
• Used in pharmaceutical topical preparations for controlled drug release and skin feel.
• Texture modifier and dispersing aid in makeup products like foundations and lipsticks.
• Conditioning agent in hair care products such as conditioners and styling creams.
• Additive in industrial applications requiring emulsification, such as lubricants and coatings.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain stability and prevent degradation. Keep away from strong oxidizing agents.
