According to the innovators at Ashland, formulators often face challenges in effectively solubilizing solid organic UV filters like bemotrizinol, triazines or triazone derivatives. As such, the specialized polar X-Tend 226 ester was designed to overcome this common formulation hurdle, enhancing the performance and stability of modern sun care products.
Enhancing Formulation Efficiency and Performance
X-Tend 226 Ester (INCI: Phenethyl Benzoate) is a proprietary polar ester distinguished by its high solubilizing capacity for solid organic UV filters, per the company. The ingredient's primary function is to prevent these filters from crystallizing over time. By preventing crystallization, the ingredient helps to deliver consistent protection throughout a product's shelf life.
Streamlining Sun Care Development
When used with other common solvents, X-Tend 226 ester is said to improve formulation efficiency. It can reduce the required amount of the oil phase and the need for certain emulsifiers. This not only facilitates greater stability, but also positively impacts the sensory feel of the final product.
The ability to streamline the formulation process contributes to improved cost-effectiveness and preservation, Ashland reports. Its benefits extend beyond sun care, showing utility in applications such as hair serums and hair sprays, where it imparts emolliency and shine.
