PEG-40 HYDROGENATED CASTOR OIL/IPDI COPOLYMER.

Insufficient Data / FILM FORMING, SKIN CONDITIONING - MISCELLANEOUS, SKIN PROTECTING, SLIP MODIFIER, SURFACE MODIFIER

This specialized copolymer primarily functions as a film-forming and skin-conditioning agent in precision skincare formulations. It creates a continuous film on the skin's surface, offering protective benefits and enhancing product texture. Its multifaceted nature contributes to overall skin health and product elegance.

Summary

Film-forming Skin-conditioning Skin protecting Slip modifier Surface modifier Emulsifier (contributed by PEG-40 Hydrogenated Castor Oil component) Solubilizer (contributed by PEG-40 Hydrogenated Castor Oil component) Surfactant (contributed by PEG-40 Hydrogenated Castor Oil component) Emollient (contributed by PEG-40 Hydrogenated Castor Oil component)

Science

Mechanism of Action

PEG-40 HYDROGENATED CASTOR OIL/IPDI COPOLYMER exerts its effects by forming a cohesive, continuous film on the skin, hair, or nails upon application, thereby serving as a robust skin protecting and conditioning agent. Beyond its barrier-forming properties, it also acts as a slip modifier, optimizing ingredient flow, and a surface modifier, altering surface characteristics for a smoother feel. The PEG-40 Hydrogenated Castor Oil portion of the copolymer contributes additional benefits, functioning as an emulsifier to stabilize oil-water blends, a solubilizer, a surfactant to aid in cleansing, and an emollient to reduce transepidermal water loss and enhance skin hydration.

Stability

The PEG-40 Hydrogenated Castor Oil component of this copolymer is stable in the presence of various electrolytes and maintains good stability in low pH environments. However, it is prone to hydrolysis and decomposition in high pH conditions. Being non-ionic, it is generally active across both acidic and alkaline formulations. Optimal stability for the PEG-40 Hydrogenated Castor Oil component has been noted within a pH range of 5.5-7.0 (at a 3% concentration in water).

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed PEG-40 HYDROGENATED CASTOR OIL/IPDI COPOLYMER. While the CIR concluded that PEGylated oils, including PEG-40 Hydrogenated Castor Oil, are safe for use up to 100% when formulated to be non-irritating, the presence of the IPDI component in this copolymer has been noted as a factor requiring distinct consideration. Due to this, the specific copolymer lacks comprehensive reviewed research, resulting in an 'unknown' safety rating from INCIDecoder and 'not rated' status from Paula's Choice. Its component, PEG-30 and -40 hydrogenated castor oil, has FDA approval as direct and indirect food additives.

Verdict

Insufficient Data

While PEG-40 HYDROGENATED CASTOR OIL/IPDI COPOLYMER offers valuable film-forming, conditioning, and textural benefits, the current lack of specific comprehensive safety and clinical efficacy data for the copolymer itself suggests its precise impact and suitability require further research.
