 Applications 

1.Nonionic Emulsifier For Oil In Water Systems: Glyceryl monostearate (CAS 31566-31-1) is a nonionic emulsifier that brings oil and water phases together into a stable emulsion, helping formulators build creams, lotions and emulsion systems that resist separation during storage and transport.

2.Personal Care And Cosmetic Formulations: Used as an emulsifier, opacifier and bodying agent in creams, lotions, antiperspirants, hair care products and sunscreens, where it improves texture, builds consistency and keeps the formula evenly dispersed.

3.Food Emulsifier And Stabiliser: In baked goods, margarine, ice cream and confectionery it emulsifies, stabilises and prevents caking, helping processors extend shelf life and improve mouthfeel in finished products.

4.Plastic Processing Aid: Serves as an internal and external lubricant in PVC and polyolefin processing and as an antistatic and anti-fogging agent in films and food packaging film, reducing surface friction, static buildup and fogging.

5.Textile And Industrial Applications: Acts as a lubricant and antistatic agent in textile processing and as an emulsifying and lubricating additive in industrial formulations, supporting smoother fibre handling and fewer static-related defects.



Quality Assurance  Quality Assurance 


Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
