1. What is Polyglyceryl-10 Oleate? How does it work?

Polyglyceryl-10 oleate, also known as polyglycerol-10 oleate, is a polyglycerol fatty acid ester formed by the partial esterification of decaglycerol and oleic acid (CAS number 9007-48-1). It is a light yellow, viscous liquid whose molecules consist of a hydrophilic polyglycerol head with multiple hydroxyl groups and a hydrophobic oleic acid chain. It is a typical nonionic surfactant with a high HLB value and prominent hydrophilicity. With its multiple properties including emulsification, dispersion, lubrication, and anti-fogging, it is widely used in plastics processing, pesticide formulations, metalworking fluids, textile auxiliaries, and industrial cleaning—this is precisely the core role it plays in industrial formulations.

Basic information : Chinese name: Polyglyceryl-10 oleate (also known as decaglyceryl monooleate, polyglyceryl-10 monooleate); English name: Polyglyceryl-10 Oleate (INCI name); CAS number: 9007-48-1; Composition: Partial esterification of decaglyceryl and oleic acid; Appearance: Light yellow viscous liquid, slightly sweet taste; Insoluble in cold water and hot water, it can be dispersed into an emulsion upon stirring; Soluble in glycerol, propylene glycol, hot ethanol, etc.; HLB value: Approximately 8-14.5 (decaglyceryl is in the higher range); Melting point: Below 0℃; Synonyms: Decaglyceryl monooleate, Decaglyceryl monooleate, etc.

Structurally , polyglycerol-10 oleate is a product of partial esterification of polyglycerol and oleic acid: the hydrophilic portion is a polyhydroxy chain with 10 glycerol units linked by ether bonds, densely packed with hydroxyl groups; the hydrophobic portion is a long C18 chain of oleic acid (cis-9-octadecenoic acid) linked to the polyglycerol chain by ester bonds. Overall, it exhibits an amphiphilic structure with a hydrophilic head of polyhydroxyl groups and a hydrophobic tail of a long chain, belonging to the nonionic surfactant category—the polyhydroxyl groups impart strong hydrophilicity and high HLB, while the oleic acid chain provides hydrophobic anchoring, which is the structural basis for its role in industrial emulsification, dispersion, and lubrication.

Physically , polyglycerol-10 oleate is a light yellow viscous liquid, odorless, and slightly sweet; it is insoluble in cold water, but can be dispersed into an emulsion in hot water with stirring; it is soluble in glycerol, propylene glycol, hot ethanol, and cold ethyl acetate, etc.; its melting point is below 0℃; its HLB value is approximately 8-14.5, with the decameric version falling in the higher range, indicating prominent hydrophilicity; its LogP value is negative; it is a highly fluid liquid at room temperature, facilitating industrial formulation processing and addition.

Chemically , polyglycerol-10 oleate is a nonionic surfactant: it does not contain ionic groups in its molecule, does not become ineffective due to electrolytes, hard water, or acidic or alkaline environments, and has good compatibility; the ester bond can be slowly hydrolyzed under strong acid, strong alkali, or prolonged high temperature conditions; it is thermally stable and stable at industrial processing temperatures; it is non-toxic, non-irritating, and has mild chemical properties.

Why does Polyglyceryl-10 Oleate play these roles in industries such as plastics processing, pesticide formulation, metalworking fluids, and textiles? Its mechanism of action mainly includes the following:

High HLB oil-in-water emulsion mechanism : Decaglycerol has a high HLB value (approximately 13-14.5) and outstanding hydrophilicity, making it suitable for forming oil-in-water emulsions, which stably disperse oily components in the aqueous phase—the basis of metalworking fluids, pesticide emulsifiable concentrates, and industrial emulsion systems.

Interfacial adsorption and tension reduction mechanism : Amphiphilic molecules adsorb at the oil-water and solid-liquid interfaces, reducing interfacial tension and helping oily components disperse in water and particles suspend in the medium—a common principle in dispersion and emulsification applications.

Lubrication and friction reduction mechanism : Polyglycerol esters adsorb onto the interface between plastic and metal processing to form a lubricating film, reducing friction and adhesion—the basis of internal lubrication in PVC and cutting fluid lubrication.

Anti-fogging film-forming mechanism : Hydrophilic esters form a uniform hydrophilic film on the film surface, causing condensed water vapor to spread into a transparent water film rather than fog droplets—the basis of anti-fogging agents for agricultural films and packaging films.

Nonionic resistance to media mechanism : Nonionic surfactants are not affected by electrolytes, hard water and acids and alkalis, maintain stable performance in complex industrial formulations and have a wide compatibility range.

Summary

Polyglyceryl-10 oleate (CAS 9007-48-1) is a nonionic surfactant partially esterified from decaglycerol and oleic acid. The hydrophilic head of the polyglycerol provides high HLB and strong hydrophilicity, while the hydrophobic chain of oleic acid provides emulsification and lubrication. This amphiphilic structure allows it to stabilize oil-in-water emulsions, lubricate and reduce friction at plastic interfaces, and prevent fogging on film surfaces . It is used in agricultural and packaging films for fog prevention, in cutting fluids for lubrication and cooling, in pesticide emulsifiers for emulsifying pesticide solutions, and in PVC processing to assist in molding. It serves the plastics, agrochemical, machinery, and textile industries as a discreet industrial additive. Understanding its high HLB amphiphilic structure explains why it can become a versatile emulsifier and additive component in industrial formulations.
