PALM OIL PEG-8 ESTERS.

Valuable / SKIN CONDITIONING - EMOLLIENT, SURFACTANT - EMULSIFYING

PALM OIL PEG-8 ESTERS acts as a multifunctional ingredient, primarily conditioning the skin by softening and smoothing its texture. It also functions as an emulsifier, expertly blending oil and water phases in formulations, while its PEG-8 component can offer hydration and enhance ingredient penetration.

Summary

Emollient Emulsifying Humectant Solvent

Science

Mechanism of Action

This ingredient operates on several fronts: as an emollient, it forms a protective layer on the skin's surface, reducing moisture loss and improving tactile smoothness. As an emulsifying surfactant, it lowers the surface tension between immiscible liquids like oil and water, ensuring stable, homogenous mixtures. Furthermore, the PEG-8 moiety can draw moisture into the skin, acting as a humectant for hydration, and also serves as a solvent to optimize the absorption of other cosmetic components.

Key findings

  1. 01 A 3.0% formulation containing PEG-8 demonstrated a moderate potential for mild cumulative skin irritation.
  2. 02 PEG-8 was observed to cause mild instances of immediate hypersensitivity. However, broad clinical testing on individuals with normal skin confirmed it was not a sensitizer, with a large study on eczematous skin showing only a 0.3% positive reaction rate.

Stability

Polymer fatty acid esters generally exhibit good thermal stability under neutral conditions, remaining stable below 100°C. However, their ester linkage makes them susceptible to accelerated hydrolysis in the presence of strong acids or strong bases.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The CIR Expert Panel deems PALM OIL PEG-8 ESTERS and similar PEGylated oils safe when formulated to be non-irritating. However, the presence of polyethylene glycols (PEGs) raises concerns about potential contamination with manufacturing impurities like ethylene oxide and 1,4-dioxane, a concern also highlighted by the EWG. Clinical data indicated that a 3.0% PEG-8 formulation could elicit mild cumulative irritation, and while not a general sensitizer for normal skin, PEG-8 has been linked to mild immediate hypersensitivity.

Our Assessment

Verdict

Valuable

PALM OIL PEG-8 ESTERS is a valuable multi-functional ingredient offering emollience, emulsification, and hydration, deemed safe by CIR when formulated non-irritating, but warrants caution due to potential irritation at higher concentrations and manufacturing impurity concerns.
