In the ever-evolving world of cosmetic science, achieving optimal performance and stability in formulations is paramount. For manufacturers of inorganic sunscreens, a key challenge lies in effectively dispersing mineral UV filters like zinc oxide (ZnO) and titanium dioxide (TiO2). These particles, crucial for providing broad-spectrum protection, can easily agglomerate, leading to reduced efficacy, uneven application, and undesirable texture. NINGBO INNO PHARMCHEM CO.,LTD. offers a powerful solution: PEG-26-PPG-30 Phosphate, a sophisticated dispersant designed to overcome these formulation hurdles.

PEG-26-PPG-30 Phosphate functions by forming a protective molecular film around each inorganic particle. This film, created through strong bonding with the particle surface, utilizes the distinct hydrophilic (EO) and hydrophobic (PO) characteristics of the molecule to create an anti-bonding effect in water. This sophisticated interaction prevents particles from clumping together, thereby improving the dispersion stability of inorganic pigments. Manufacturers seeking to achieve superior dispersion stability of inorganic pigments will find this ingredient invaluable.

The benefits of using PEG-26-PPG-30 Phosphate extend beyond mere dispersion. By enabling a more stable and uniform suspension, it allows for a significant reduction in the viscosity of cosmetic dispersions. This is a critical advantage as it permits formulators to increase the pigment concentration in their formulas without compromising processability. Higher pigment concentration translates directly into more effective UV protection and richer, more opaque color pay-off in the final product. Consequently, the ability to reduce viscosity of cosmetic dispersions is a key enabler for innovative product development.

Furthermore, enhanced dispersion directly correlates with improved UV absorption. When inorganic particles are evenly distributed and not clumped, their surface area available for absorbing or reflecting UV radiation is maximized. This means that products formulated with PEG-26-PPG-30 Phosphate can achieve higher SPF values and better UVA/UVB protection. The prevention of powder aggregation in cosmetics is therefore not just about aesthetics, but also about efficacy. For those interested in improving UV absorption in sunscreens, this ingredient is a must-consider.

The practical application of PEG-26-PPG-30 Phosphate is straightforward. It is recommended to dissolve the dispersant in water before neutralizing and adjusting the pH to 6-8. The inorganic sunscreen or pigment is then added while stirring. The recommended dosage is typically much lower than traditional dispersants, often 1/20th for ordinary powders and 1/10th for nano powders, though optimization may be needed based on specific production processes. This efficiency further underscores its value as a cosmetic raw material for sunscreens.

In summary, PEG-26-PPG-30 Phosphate from NINGBO INNO PHARMCHEM CO.,LTD. offers a comprehensive solution for formulators aiming to create high-performance inorganic sunscreens and makeup products. Its ability to improve dispersion stability, reduce viscosity, increase pigment concentration, enhance UV absorption, and prevent powder aggregation makes it a vital ingredient for achieving superior product quality and efficacy. For businesses looking to elevate their cosmetic formulations, exploring the capabilities of this advanced dispersant is a strategic move.
