Polyglyceryl-10 Stearate Blocky Solid: pH-Independent O/W Emulsifier for Lotions

HERSONCARE Polyglyceryl-10 Stearate – cream white to light yellow blocky solid, multi-functional non-ionic O/W emulsifier.

Product Overview

HERSONCARE Polyglyceryl-10 Stearate (Decaglyceryl Stearate, PGL-10S) is a plant-derived non-ionic O/W emulsifier supplied as blocky solid, with powder and granule forms available. The blocky solid is added to the oil phase and melts at approximately 55°C before emulsification — a process detail that matters for lotion and cream systems with a defined heating phase.

Its key advantage is pH-independent emulsification. Many natural emulsifiers lose stability under acidic or high-electrolyte conditions; PGL-10S maintains consistent O/W performance across the full pH range, making it suitable for acid-based lotions, electrolyte-containing actives, and sensitive-skin formulas. It also delivers stabilization and thickening, reducing co-emulsifier count. The product shows antimicrobial activity against heat-resistant Bacillus species and is manufactured with undetectable lead content. HERSONCARE supplies it alongside Cosmetic Azelaic Acid, Sodium Hyaluronate, and D-delta Mixed Tocopherols. Bulk wholesale, custom blends, and samples are available.

Polyglyceryl-10 Stearate Structure

Technical Specifications

Parameter Specification
Color / Form Cream white to light yellow; powder, granule, blocky solid
Acid Value 0.7 mgKOH/g
Iodine Value 0.7 gI₂/100g
Saponification Value 93 mgKOH/g
Lead Absent (undetectable)
HLB Approximately 11–13 (O/W)
Solubility Soluble in oils/fats; slightly soluble in ethanol/acetone; insoluble in water

Read three values on the COA together: acid value (0.7, low free fatty acid), iodine value (0.7, low unsaturation and resistance to oxidative yellowing), and saponification value (93, reflecting the polyglyceryl-10 stearate structure). Undetectable lead is a separate compliance point for food-contact and sensitive cosmetic applications. Excellent thermal stability and light resistance.

Product Features and Advantages

pH-Independent Emulsification

Consistent O/W emulsification across the full pH range without compromise — critical for acidic lotions, electrolytes, and pH-sensitive natural ingredients.

Superior O/W Emulsion Stability

Forms stable oil-in-water emulsions and prevents phase separation. Melts into the oil phase at ~55°C, integrating fully into the emulsion structure.

Antimicrobial Protection

Strong inhibition against heat-resistant Bacillus species, providing preservation support alongside emulsification.

Multi-Functional: Emulsifier, Stabilizer, Thickener

Three functions in one ingredient, reducing co-emulsifier count and simplifying lotion and cream formulations.

Green, Safe, Non-Irritating

Plant-derived, non-ionic, and non-irritating, suitable for sensitive-skin lotions. Undetectable lead supports cosmetic and food-grade compliance.

Why HERSONCARE

  • Proprietary decolorization and deodorization for low-odor, low-color product.
  • Technical support for oil-phase addition, melting temperature, and emulsion design.
  • Integrated portfolio including Cosmetic Azelaic Acid, Sodium Hyaluronate, and D-delta Mixed Tocopherols.

How to Use Polyglyceryl-10 Stearate

  1. Form selection: choose powder, granule, or blocky solid based on batching and melting process.
  2. Incorporation: add to oil phase with gentle heating to ~55°C; blocky solid melts before emulsification.
  3. Dosage: 0.5–5%; typical cosmetic lotion usage 1–3%.
  4. Compatibility: test with Plant Extract materials and electrolytes before scale-up.
  5. Stability testing: confirm emulsion stability, viscosity, and texture under intended storage conditions.

Application Scenarios

Cosmetics and Personal Care – Lotions and Creams

Used in skincare, haircare, and color cosmetics for stabilization and texture enhancement. Particularly suited to O/W lotions, face creams, body lotions, gel-creams, and sprayable lotions requiring pH-independent emulsification.

Food and Beverage

Used in coffee, soy milk, baked goods, and ice cream for emulsion stability and shelf life extension. Antimicrobial activity against heat-resistant Bacillus species provides preservation support in canned and bagged foods.

Industrial Uses

Feed, coatings, textiles, and papermaking applications requiring emulsification and dispersion, where a pH-independent non-ionic emulsifier is preferred over ethoxylated alternatives.

Benefits for Customers

Enhanced Stability and Texture

Stable O/W emulsions with consistent texture across pH ranges, reducing batch failures and reformulation cycles.

Extended Shelf Life

Antimicrobial action against heat-resistant Bacillus species provides preservation support in food and cosmetic applications.

Reduced Formulation Complexity

One ingredient delivers emulsification, stabilization, and thickening, reducing co-emulsifier count.

pH Flexibility

Consistent performance across the full pH range supports acidic lotions and electrolyte-containing actives without additional stabilizers.

Flexible MOQ and Documentation

Available in 1 kg, 5 kg, and 25 kg packaging. COA, MSDS, and specification sheets support EU, US, and Asia-Pacific market entry.

  • Packaging: flexible options from 1 kg to 25 kg drums.

Custom requests evaluated within 48 hours; pre-shipment sample before full production.

Production Process and Quality Control

  1. Raw material selection: plant-derived fatty acid and glycerol sources verified for identity and purity.
  2. Precision polymerization: controlled polycondensation of glycerol to build the polyglyceryl-10 backbone.
  3. Optimized esterification: controlled reaction with stearic acid to form the target monoester profile.
  4. Proprietary purification: decolorization and deodorization with lead removal verified.
  5. Form conversion and packaging: conversion to powder, granule, or blocky solid with protective packaging.

Batch records and COAs retained for traceability. Shelf life 2 years in original unopened packages stored in cool, dry conditions.
