In response to the demand of both mass and prestige consumers in the personal care market for products with more multi-tasking benefits, Shin-Etsu Silicones of America has recently developed TSPL-30-ID (INCI: Isododecane (and) Trimethylsiloxysiylcarbamoyl Pullulan), a multifunctional  siliconized pullulan film-former in isododecane that was designed for long-wear lip applications.

Silicone modification renders the pullulan polymer with excellent water repellency and oil repellency, which are the key elements for achieving anti-transfer benefits for long wear lip applications. Silicone moiety further modifies the film flexibility for comfort and a non-tacky feel without compromising the adhesion properties. Additionally, the product can form a gel structure when combined with ingredients capable of forming H-bonding with TSPL. These ingredients include: silicone/acrylate film formers, amino gums and fluids, emulsifiers, and self-emulsifying elastomers, etc. The gelled systems enhance the stability of pigmented products without sacrificing the film-forming properties.

 While uniquely suited for the growing lipstick segment, the product’s multi-dimensional makeup delivers essential stability, functionality, and sensory benefits across a myriad of personal care applications including: color cosmetics such as foundations, eye shadows, mascaras, lipsticks, blushers, pencils, etc.; skin lotions and creams; sun care products such as lotions, creams and self-tanners; and anti-aging products.
