Science
Mechanism of Action
This ingredient operates on multiple levels to optimize skin condition and product performance. It forms a lightweight yet effective protective barrier on the skin's surface, shielding against environmental stressors and contributing to sustained moisture retention. As an emollient, it imbues the skin with a soft texture by enhancing its lipid content and reducing transepidermal water loss. The copolymer also functions as a humectant, attracting and retaining water, thereby boosting hydration both within the formulation and on the skin. Furthermore, its emulsifying and surfactant properties are crucial for stabilizing cosmetic products by effectively blending immiscible oil and water phases, leading to consistent and homogeneous textures. It also offers viscosity control, allowing for adjustments in product thickness and contributing to a smooth, non-greasy application experience.

The Formula
Formulation
Stability
This copolymer exhibits characteristics conducive to robust formulation stability, drawing parallels to related ingredients like Polyglyceryl-3 Diisostearate, which demonstrate notable thermostability and resistance to acidic conditions. It plays a critical role in preventing phase separation, creaming, and coalescence within emulsions, thereby upholding the desired texture and visual uniformity over time. Its capacity to form stable emulsions across various water-to-oil ratios provides considerable flexibility in product development.
Safety
Safety Profile
Generally regarded as safe for use in cosmetic applications, with regulatory bodies such as the European Commission having approved its inclusion. Clinical observations indicate a low propensity for allergic reactions or skin irritation, making it suitable for a broad range of individuals. SkinSAFE classifies it as 'Irritant Free', 'Baby SAFE', and 'Sensitive Skin Safe'. The EWG Skin Deep® database assigns it a 'LOW' concern rating across categories including cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. While the CIR Expert Panel deemed a related compound, 'Diisostearoyl Polyglyceryl-3 Dimer Dilinoleate', safe when formulated to be non-irritating, specific concentration limits for POLYGLYCERYL-3 STEARATE/ISOSTEARATE/DIMER DILINOLEATE COPOLYMER were not explicitly identified in the provided research.
