TRIMETHYLSILOXYSILICATE is the co-hydrolysis product of tetraalkoxysilane (Q unit) and trimethylethoxysilane (M unit). The chemical structure of TRIMETHYLSILOXYSILICATE can be seen as a three-dimensional network of polysilic acid units, which are endblocked with trimethylsilyl groups. Some residual ethoxy and hydroxy functions are present. TRIMETHYLSILOXYSILICATE is a white powder manufactured in such a way that it is substantially free of aromatic solvents such as toluene. In keeping with its low content of fine dust particles and its uniform particles, TRIMETHYLSILOXYSILICATE exhibits excellent rheological properties (flowability). TRIMETHYLSILOXYSILICATE can be compounded with polydimethylsiloxanes.

This highly cross-linked silicone resin is primarily used for its film-forming attributes. In sunscreen, skincare and color cosmetic applications, the Trimethylsiloxysilicates an excellent water-resistant additive and helps to hold pigments in place. It prevents agglomeration

Advanced Film-Forming Agent for Cosmetics

Trimethylsiloxysilicate (TMS) provides robust, transparent, and flexible films that enhance water resistance and transfer-proof properties in personal care products. Its non-tacky finish and compatibility with a range of cosmetic solvents make it ideal for formulations such as mascaras, lipsticks, and sunscreens. TMS improves product durability and adhesion to the skin, ensuring long-lasting, comfortable wear.

Outstanding Physical and Chemical Stability

This siloxane polymer is chemically stable, neutral in pH, and has a high flash point (>100C), ensuring safety and performance during processing and usage. It is insoluble in water yet mixes seamlessly with esters and alcohols, allowing versatility in product design. With a shelf life of 2 years, Trimethylsiloxysilicate maintains integrity and effectiveness in extended storage under proper conditions.

FAQs of Trimethylsiloxysilicate TMS:

Q: How is Trimethylsiloxysilicate (TMS) typically used in cosmetic formulations?

A: Trimethylsiloxysilicate acts as a film-forming agent, waterproofing enhancer, and adhesion promoter in cosmetics, including foundations, eyeliners, mascaras, and sunscreens. Its flexible, durable films help improve product longevity and resistance to water and smudging.

Q: What are the main benefits of using Trimethylsiloxysilicate in personal care products?

A: The principal advantages of TMS include non-tacky, transparent films that boost wear resistance and water repellency. Its compatibility with silicone oils and esters ensures smooth blending in diverse formulations while maintaining skin comfort and durability.

Q: When should I add Trimethylsiloxysilicate during the cosmetic manufacturing process?

A: TMS should be incorporated during the blending stage, typically with the solvent phase, to maximize dispersion and compatibility. It is stable at typical cosmetic processing temperatures and remains effective throughout the products shelf life.

Q: Where can Trimethylsiloxysilicate be sourced and in what packaging options?

A: Manufacturers, suppliers, and distributors across India offer Trimethylsiloxysilicate in 1 kg, 5 kg, and 25 kg HDPE drums, ensuring safe transport and handling for both industrial and cosmetic-grade needs.

Q: What storage conditions are recommended for maintaining TMS quality?

A: Store TMS in a cool, dry place away from direct sunlight. The tightly sealed HDPE drums protect it from moisture and contamination, helping preserve its properties for up to two years.

Q: Is Trimethylsiloxysilicate safe for use and how should handling be approached?

A: TMS is non-toxic, odorless, and tasteless, posing no significant health risks under standard conditions. However, as with all chemical raw materials, appropriate safety measures such as gloves and eye protection are recommended during handling.

Q: Does Trimethylsiloxysilicate offer solubility with water or other common solvents?

A: TMS is insoluble in water but dissolves well in alcohols and esters, making it versatile for formulations that require unique solvent profiles and enhancing blends in oil-based cosmetics.
