Surfactants are fundamental to modern cosmetic formulations, enabling the creation of stable and aesthetically pleasing products by bridging immiscible substances. Among the diverse range of surfactants, PEG-30 Dipolyhydroxystearate (CAS 70142-34-6) stands out for its specialized function as a polymeric water-in-oil (W/O) emulsifier. NINGBO INNO PHARMCHEM CO.,LTD. highlights this ingredient's critical role in formulating advanced personal care products.

Chemically, PEG-30 Dipolyhydroxystearate is a derivative of polyethylene glycol and dipolyhydroxystearic acid. This structure provides it with amphiphilic properties – meaning it has both water-loving (hydrophilic) and oil-loving (lipophilic) parts. This dual nature is the key to its effectiveness as an emulsifier. It positions itself at the interface between oil and water droplets, reducing the surface tension and allowing these phases to mix and remain dispersed, forming a stable emulsion.

As a W/O emulsifier, PEG-30 Dipolyhydroxystearate is particularly adept at creating formulations where oil is the continuous phase and water is dispersed in small droplets. This is characteristic of many richer creams and lotions that provide deep moisturization and emollience. Its polymeric nature contributes to enhanced stability, providing resilience against factors like temperature fluctuations and high electrolyte concentrations, which can destabilize simpler emulsions. This makes it a reliable choice for cosmetic raw material moisturizing applications where sustained hydration is key.

The ingredient’s role as a surfactant extends to its ability to improve the solubility and dispersion of other ingredients within a formulation. For instance, in sunscreen formulation, it helps to uniformly disperse UV filters, ensuring maximum efficacy. In color cosmetics, it aids in the even distribution of pigments, leading to better color payoff and a smoother application. The characteristic light skin feel it imparts also contributes to its appeal, enhancing the overall sensory experience of the final product.

NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that understanding the chemical function of ingredients like PEG-30 Dipolyhydroxystearate is vital for formulators. Its properties as a high-performance surfactant enable the creation of sophisticated, stable, and consumer-appealing cosmetic products. Whether aiming for enhanced hydration, improved pigment dispersion, or superior emulsion stability, this versatile ingredient offers a robust solution for a wide array of personal care applications.
