PEG-240/HDI COPOLYMER BIS-DECYLTETRADECETH-20 ETHER.

Valuable CAS - / LIGHT STABILIZER, VISCOSITY CONTROLLING

PEG-240/HDI COPOLYMER BIS-DECYLTETRADECETH-20 ETHER is a multifunctional polymer utilized in skincare for its precise control over product viscosity, often creating desirable gel textures. It also functions as an effective emulsifier and stabilizer, ensuring formula integrity and smooth application, while providing mild conditioning benefits to the skin.

Science

Mechanism of Action

This ingredient optimizes product characteristics by acting as a viscosity-controlling agent, capable of adjusting thickness and forming gel textures in aqueous formulas. It serves as an emulsifier, enabling the uniform dispersion of immiscible phases, and a stabilizer, protecting formulations from separation and light-induced degradation. On the skin, it contributes to a softened, moisturized feel, strengthens the skin's protective barrier, and may facilitate the deeper delivery of active compounds. As a PEG derivative, it additionally enhances product consistency and offers humectant properties.

Key findings

  1. 01 Clinical data predominantly address the safety profile and formulation functionality, rather than specific skin efficacy endpoints. While it effectively creates gel textures and stabilizes emulsions, quantitative studies on its direct skin benefits (e.g., precise moisturizing efficacy at specific concentrations) are not detailed in the provided research.

Dusting Analysis

Not commonly dusted

PEG-240/HDI COPOLYMER BIS-DECYLTETRADECETH-20 ETHER is valued as a functional ingredient for its formulation benefits, such as viscosity control and stabilization, rather than for direct 'dusted' active claims in marketing.

Stability

This ingredient, a white to light yellow powder, maintains stability across a wide pH spectrum of 2-10. For integration into formulations, it should be dispersed in the water phase and gently heated to melt, ensuring temperatures do not exceed 80°C. Optimal storage is at room temperature (25-40°C) in a tightly sealed container, shielded from sunlight or heat, ensuring a shelf life of at least 3 years.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
30%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) deems this ingredient safe for use, noting the absence of residual hexamethylene diisocyanate (HDI) (<20 ppm) in tested batches. It demonstrated no genotoxicity and exhibited no dermal irritation or allergic contact sensitization in Human Repeat Insult Patch Tests (HRIPT). Guinea pig irritation assays further confirmed its non-irritant status at concentrations up to 30%. Ocular studies (BCOP assay score of ~2.74, indicative of non-irritancy) support its mild profile. While generally well-tolerated across all skin types, a patch test is recommended for individuals with highly sensitive skin due to the rare potential for allergic reactions.
