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.
Formulating Strategies in Cosmetic Science includes an entire section on emulsions including evaluating new emulsions, optimizing emulsions and technology. You will also find formulating for infant care products such as wipes and underarm personal care formulating. Want to know more?
