POLYGLYCERYL-10 PENTAHYDROXYSTEARATE.

Valuable / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

Polyglyceryl-10 Pentahydroxystearate is a versatile plant-derived water-in-oil emulsifier, engineered to create stable and exceptionally light-textured emulsions. It also functions as a skin conditioning agent and emollient, contributing to skin softness, smoothness, and enhanced hydration by supporting the skin's moisture barrier.

Science

Mechanism of Action

Operating as a plant-derived water-in-oil (W/O) emulsifier, Polyglyceryl-10 Pentahydroxystearate effectively blends disparate water and oil phases, stabilizing emulsions even in challenging polar, oil-rich, or low-viscosity systems, resulting in a remarkably lightweight product feel. On the skin, it delivers emollient benefits, promoting a soft and smooth epidermal texture. Furthermore, it aids in hydration by forming a subtle film that helps to occlude moisture and prevent transepidermal water loss.

Stability

Polyglyceryl-10 Pentahydroxystearate consistently forms stable emulsions. However, its inherent ester linkage is susceptible to hydrolysis, a process that can be accelerated by the presence of strong acids or bases, potentially compromising emulsion integrity.

Conflicts

  • Strong acids or bases, due to their potential to accelerate ester hydrolysis.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The CIR Expert Panel has concluded that Polyglyceryl-10 Pentahydroxystearate is safe for use in cosmetics, provided formulations are non-irritating. Polyglycerol esters (PGEs) in general are noted for being biodegradable, biocompatible, non-carcinogenic, and non-toxic, with no adverse effects observed at a test concentration of 5 wt%. While EWG Skin Deep rates this ingredient with a LOW concern for Cancer, Allergies, and Developmental Toxicity, specific skin, eye, or lung irritation data is currently 'unknown/unassessed' by CIR.
