Isotridecyl Isononanoate

Product Introduction

Isotridecyl Isononanoate (ITIN) is a highly branched synthetic ester, renowned in the fine chemical industry as the "cushion pad for high-end color cosmetics." Its unique dual-branched structure imparts exceptional oxidative stability, an extremely low freezing point, and an unmatched silky, rich yet non-greasy feel. As the perfect drop-in replacement for High-Sorbitol Kak 139 and higher alcohol 139, ITIN achieves genuine domestic substitution and equivalent upgrade in skin feel formulation.

Leveraging a tube-tank external circulation deep vacuum light-end stripping system, we achieve full liquid-phase production with zero impurity filter cake, and effectively strip free alcohols at the end of the reaction, ensuring extremely low acid value and odor residue. Its low viscosity of approximately 10 mPa·s at 25°C makes it an ideal engineering-grade oil for high-end color cosmetics and sun care systems. For silk oil replacement needs, ITIN offers superior batch-to-batch consistency and enhanced supply chain resilience.

Deep Application Fields & Formulation Recommendations

In high-end color cosmetics (e.g., foundation, primer, lip gloss), ITIN is an indispensable core dispersant. Its remarkable wetting and dispersing ability for titanium dioxide, zinc oxide, organic UV filters, and various organic pigments effectively solves process issues such as caking, whitening, and uneven color distribution in foundations. Its unique molecular structure provides an excellent thick cushion effect, delivering a silky application that naturally blends into the skin. Additionally, in anti-aging creams for "AM/PM" routines, it serves as a high-quality emollient base, providing long-lasting moisturizing occlusion without causing comedogenic risks.

Handling & Operation Tips

Recommended usage level is 1% to 20%. This product exhibits excellent compatibility in the oil phase, with high heat resistance and oxidation stability. It performs exceptionally well in high-shear processes such as high-temperature homogenization or color paste milling, significantly enhancing the luxurious skin feel and suspension stability of final products.
