Consumers demand more long-wear options for their cosmetic applications—notably in the lip color and foundations segment. In conjunction with this, secondary demands like transfer resistance, color persistence and color shifting continue to grow without sacrificing comfort.
To address these long-lasting trends, Shin-Etsu Silicones of America (SESA) recently featured its advanced line of silicone film former technologies for longer wear and comfort.
SESA demonstrated how its long-wear silicone film former technologies overcame these issues to provide excellent durability and improved flexibility for added comfort. Both water and oil repellency (key elements for achieving anti-transfer benefits) were also achieved. Formulators can choose from a key range of SESA’s unique, long-wear products which includes a hard type MQ resin (in combination with an amino gum blend), as well as siliconized pullulan film formers to minimize transfer and extend wear in lip and foundation applications. Key SESA long-wear silicone film former solutions featured include: TSPL-30-ID: SiliconeModifiedPullulan and INCI: TSPL-30-ID: Isododecane (and) Trimethylsiloxysiylcarbamoyl Pullulan (TSPL).
This patented, multi-functional silicone modified pullulan film former in isododecane offers formulators simultaneous properties engineered to achieve anti-transfer benefits for long wear lip applications. This material has “outstanding” oil repellency, which contributes to the long-lasting effect. It is also oil resistant, tough, flexible and features a larger molecular weight than MQ resin−making it even more durable. It is comfortable, with a non-tacky feel without compromising the adhesion properties.
Other Film Formers
Featuring the largest molecular weight in SESA’s film former portfolio, the NBN-30-ID is unique due to its hard flexible nature. The silicone modified former also excels in water and oil repellency−key for a long-lasting effect. A very rigid polymer, it provides very hard, tough, but flexible film with low tackiness. When dried, it provides a film with a smooth feeling. Highly viscous, it also has a unique feature of large spinnability and excellent adhesion capability.
The novel polymer was created by the introduction of a silicone group into a polynorbornene−a very rigid polymer that produces a tough, long-lasting film that delivers optimal transfer resistance. The end result enables the development of a diverse range of cosmetic formulations, that offer excellent resistance to oil and water for a wide range of cosmetics applications including: foundations, eye shadows, mascaras, lipsticks, skin lotions, creams, sunscreens, hair care products and more.
New Product
SESA’s newest silicone film forming agent, the KF-9021-ID, commonly known as MQ resin−a very hard type resin which makes very hard films. Due to the very hard nature of this newest grade of MQ resin, it has improved durability over SESA’s standard hard type MQ.
It is dissolved in isododecane which evaporates to leave behind a film that can improve a preparation’s water repellency and resistance to water. Comprised of approximately 50% parts Trimethylsiloxysilicate and Isododecane, it forms high strength films by volatilization of the oil agent.
Notably, it is recommended to plasticize with SESA's X-25-9007B amino modified gums to make the film more flexible and improve oil repellency without being tacky. These gums also provide a silky feeling and shine when applied to skin. Ultimately, this MQ resin film former is very hard with a non-transfer effect from the blend of amino gums and volatile diluents.
