Product Application

1. Industrial Applications (Core Uses)

Metalworking Fluids: Acts as a lubricant and rust inhibitor​ in cutting fluids, rolling oils, and wire drawing oils, reducing tool wear, improving machining precision, and preventing metal corrosion (e.g., steel, aluminum processing).

Textile Auxiliaries: Serves as an emulsifier and softener​ in textile oils and lubricants, forming a protective film on fibers to reduce friction, improve hand feel, and enhance antistatic properties (e.g., polyester, nylon spinning oils).

Pesticide Emulsifiers: Blended with anionic surfactants (e.g., calcium dodecylbenzenesulfonate) to prepare pesticide emulsifiable concentrates (e.g., herbicides, insecticides), enhancing the dispersion and adhesion of active ingredients to improve efficacy.

Coatings/Inks: Functions as a dispersant​ to prevent pigment/precipitate settling and improve coating leveling and gloss (e.g., industrial anti-corrosion coatings, printing inks).

2. Cosmetics & Personal Care

W/O Emulsifier: Used in water-in-oil creams, lotions, and sunscreens to form stable oil-water systems, providing a moisturizing, non-greasy feel.

Emollient: Improves spreadability and reduces skin tightness in hand creams and body lotions, especially suited for dry seasons.

3. Food Industry

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

Stabilizer: Prevents sugar bloom and oil separation in confectionery and baked goods, enhancing product stability.

4. 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., antifungals, antibiotics) in oral suspensions to enhance bioavailability.
