Form: liquid

Product Application

1. Cosmetics & Personal Care

W/O Emulsifier: Used in water-in-oil creams, eye creams, and sunscreens (e.g., traditional "snow cream") to provide a non-greasy, moisturizing feel.

Dispersant: Disperses oil-soluble ingredients (e.g., fragrances, vitamin E) to prevent aggregation in aqueous systems.

Emollient: Improves spreadability and reduces skin tightness in hand creams and body lotions.

2. Food Industry

Food Emulsifier: Compliant with GB 2760, used in margarine, shortening, and ice cream to reduce interfacial tension, prevent oil separation, and improve texture.

Stabilizer: Prevents sugar bloom and oil separation in chocolate and candies, enhancing product stability.

Defoamer: Suppresses foam in bean products and sugar refining, improving production efficiency.

3. Pharmaceuticals

Ointment Base: Blended with petrolatum and lanolin as a W/O emulsifier for topical ointments (e.g., eczema, dermatitis treatments) to promote transdermal drug absorption.

Drug Carrier: Disperses poorly water-soluble drugs (e.g., antibiotics) in oral suspensions to enhance bioavailability.

Injectable Solubilizer: Blended with Tween 80 to increase the solubility of poorly water-soluble drugs.

4. Industrial Applications

Textile Auxiliaries: As an emulsifier for textile softeners and lubricants, forming a lubricating film on fibers to reduce friction and improve hand feel.

Metalworking Fluids: Acts as a lubricant and rust inhibitor in cutting fluids and rolling oils, improving machining precision and preventing corrosion.

Pesticide Emulsifier: Blended with anionic surfactants (e.g., calcium dodecylbenzenesulfonate) to prepare pesticide emulsifiable concentrates, enhancing active ingredient dispersion and adhesion.

Coatings/Inks: As a dispersant to prevent pigment/precipitate settling and improve coating leveling and gloss.
