In response to the rapid demand of both mass and prestige consumers in the cosmetics market for products with more multi-tasking benefits, Shin-Etsu Silicones has recently developed its new, multi-functional TSPL-30-ID siliconized pullulan film former in isododecane.
The patented TSPL-30-ID product offers simultaneous properties engineered to achieve anti-transfer benefits for long wear lip applications, comfort and a non-tacky feel without compromising the adhesion properties. Siliconization of the pullulan polymer renders the film former highly permeable to moisture and oxygen, believed to enhance skin health and comfort. While uniquely suited for the growing lipstick segment, the product’s multi-dimensional make-up delivers essential stability, functionality and sensory benefits across a myriad of personal care applications including:
- Cosmetics: foundations, eye shadows, mascaras, lipsticks, blushers, pencils, etc.
- Skin lotions and creams
- Sun care products: lotions, creams, self-tanners
- Anti-aging products
TSPL-30-ID MATERIAL PROFILE: Isododecane (and) Trimethylsiloxysiylcarbamoyl Pullulan (TSPL)
The TSPL-30-ID’s 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 (such as the KP series offered by Shin-Etsu), 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.
- Tough Film: Forms film with high strength
- Wet Feeling: Provides film with wet feeling and low tackiness
- Flexibility: Provides flexible film while retaining hardness
- Oil Repellency: Outstanding oil repellency contributes to long-lasting effect
