Overview
-
Chemical NaturePolysorbate 40, chemically described as polyoxyethylene (20) sorbitan monopalmitate, is a hydrophilic non-ionic surfactant with a typical HLB value of 15.6.
-
Appearance & SpecsLemon-yellow to orange oily liquid or semi-gel at 25°C | Typical HLB: 15.6
-
★ Primary Application (Food/Bakery)Texture Improver.Oil-in-Water Emulsifier. Used in permitted food formulations to support emulsification, dispersion and product consistency. Suitability and use level depend on the food category and destination-market regulations.
-
Cosmetics UseFunctions as an emulsifier, dispersant and solubilizer in oil-in-water lotions, creams and selected hair-care formulations.
-

Molecular Structure
-
Structural ComponentsHydrophilic Segment: Polyoxyethylene chain comprising approximately 20 ethylene oxide units attached to the sorbitan core.Hydrophobic Moiety: Palmitate ester derived from palmitic acid.
-
★ Mechanism of ActionThe polyoxyethylene region provides hydrophilicity, while the palmitate ester provides affinity for the oil phase. This amphiphilic structure supports oil-in-water emulsification, dispersion and solubilization.
Specifications
Polysorbate 40 combines a balanced hydrophilic–lipophilic structure, making it effective for emulsifying systems with moderate oil content. The following are typical quality control parameters.

Applications
-
Food, Personal Care and Industrial FormulationsPolysorbate 40 is a hydrophilic non-ionic surfactant used mainly for oil-in-water emulsification, dispersion and solubilization. Food use must comply with the permitted categories and maximum levels of the destination market.
-
★ Food Emulsion SystemsFor grades conforming to E434 specifications, Polysorbate 40 may be used where E432–E436 are permitted, including specified fine bakery wares, desserts and other authorized emulsion systems. Application performance should be confirmed in the finished formulation.
-
Cosmetic FormulationsUsed as an emulsifier, dispersant and solubilizer in lotions, creams, hair-care products and fragrance-containing formulations.
-
Industrial FormulationsMay also be evaluated in colour materials, emulsion-polymerization systems, agrochemical adjuvants and water-based metalworking fluids.
High-HLB O/W Emulsification
With a typical HLB of 15.6, Polysorbate 40 supports oil-in-water emulsification in compatible food, cosmetic and specialty formulations.
Oil-Phase Dispersion
Helps disperse compatible oil-phase ingredients into aqueous systems under appropriate formulation and processing conditions.
Flexible Emulsifier Blending
Can be combined with compatible low-HLB emulsifiers to adjust the overall HLB balance and optimize selected emulsion systems.
Versatile Formulation Support
Suitable for evaluation in permitted food applications, personal care products and selected industrial formulations, subject to grade and regulatory requirements.



Storage & Package
