Enhancing the staying power: MQ Resin/TMS (Trimethylsiloxysilicate) in next-gen primer formulas
Makeup products must not only look good but also last longer, feel better on the skin, and resist environmental stressors like humidity and sweat. Silicone-based formulations play a key role in achieving these expectations, offering improved spreadability, smoother skin texture, and extended wear time with oxygen breathability.
Achieving a water repellent product without sacrificing comfort or longevity has always been a challenge. The blend of Dimethicone and Trimethylsiloxysilicate, a silicone blend designed to deliver a luxurious skin feel with uncompromising performance. Whether formulating a high-performance foundation or primer.
TMS Key Benefits:
- Water-Resistant Performance
- Long-Lasting Film-Forming Ability
- Supports Even Coverage & Adhesion
- Enhances Wear of Color Cosmetics & Sunscreens
Trimethylsiloxysilicate forms a flexible, breathable film on the skin, helping active ingredients or pigments adhere better and resist water, humidity, and smudging. It is particularly effective in long-wear and waterproof applications like foundations, eyeliners, and transfer-resistant lip products.
TMS Case Study:
To evaluate the impact of blend of Dimethicone and Trimethylsiloxysilicate on the overall performance of a makeup primer, focusing on key sensory and functional parameters we formulated two primers with and without TMS blend.
Key benefits in formulation observed:
- Improved water resistance
- Enhanced sensory benefits with powdery feel
- Slight improvement in matte finish
- Subtle boost in velvety feel
The addition of TMS blend significantly improved key performance of the primer, most notably water repellency, spreadability, and smoothness without compromising existing feel. It is best used in combination with other silicones like silicone cross polymer and Phenyl Trimethicone to achieve a well-balanced sensory and functional profile. Further evaluation of its wash-off performance is in progress, and we look forward to sharing the outcomes in future publications.
TMS blend is a versatile ingredient for formulators looking to boost wear longevity, ease of application, and sensory appeal in premium cosmetic products.
Elkay silicones also promotes this TMS blend/ Dimethicone and Trimethylsiloxisilicate under the brand name of LK-Q6.
