Trifluoropropyldimethyl/trimethylsiloxysilicate is a chemical compound, cocondensed silica material
and consists of:
- Trifluoropyldimethyl
is a type of siloxane, a compound containing silicon, oxygen and carbon atoms. It is often used in the production of silicone polymers, which have a wide range of applications, including cosmetics, sealants, adhesives and lubricants. Here is a general process to synthesize Trifluoropyldimethylsiloxane:
Preparation of starting materials. The first stage of the synthesis of Trifluoropyldimethylsiloxane is the preparation of raw materials. This involves the purification of Dimethyldichlorosilane and 3,3,3-trifluoropylchlorosilane.
Hydrolysis and condensation. The purified raw materials undergo hydrolysis and condensation by reaction of the silanes with water to form the silanols, which then condense to form the siloxane. The reaction is typically carried out in an acidic or basic solution.
Polymerization. The resulting siloxane can be polymerized to form a silicone polymer by connecting the siloxane molecules together in a chain in the presence of a catalyst.
Purification. The product is purified to remove any unreacted raw materials and other impurities. This can involve processes such as distillation and filtration.
Quality control. The final product is then tested to ensure it meets the required specifications. This may involve testing for parameters such as purity, viscosity and molecular weight.
- trimethylsiloxysilicate
Also known as silicone resin, it is a type of silicone compound that is often used in cosmetics due to its ability to form a flexible and durable film on the skin.
The synthesis process takes place in several stages:
Preparation of starting materials. The first phase of the synthesis of Trimethylsiloxysilicate concerns the preparation of raw materials: purification of Methyltrichlorosilane and Dimethyldichlorosilane.
Hydrolysis and condensation. The purified raw materials are hydrolysed and condensed by reaction of the silanes with water to form the silanols, which then condense to form the siloxane. The reaction is typically carried out in an acidic or basic solution.
Polymerization. The resulting siloxane can then be polymerized to form a silicone resin. This involves connecting the siloxane molecules together in a three-dimensional network and is typically carried out in the presence of a catalyst.
Purification. The product is purified to remove any unreacted raw materials and other impurities by processes such as distillation and filtration.
Quality control. The final product is then tested to ensure it meets the required specifications. This may involve testing for parameters such as purity, viscosity and molecular weight.
What it is used for and where
Cosmetics
Binder agent. Ingredient that is used in cosmetic, food and pharmaceutical products as an anti-caking agent with the function of making the product in which it is incorporated silky, compact and homogenous. The binder, either natural such as mucilage, gums and starches or chemical, may be in the form of a powder or liquid.
Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
