Silicone oil (Dimethicone) 1% related explanation

1. Applications
Silicone oil 1% shows its unique application value in many fields. In the field of medicine, it is often used as a medicinal excipient. Because of its good lubrication and chemical stability, it can help drugs pass smoothly through the gastrointestinal tract and reduce the irritation of drugs to the gastrointestinal tract. For example, in some capsules, an appropriate amount of silicone oil 1% can ensure that the contents maintain good fluidity during storage and administration, which is convenient for patients to swallow and release drugs.

In the cosmetic industry, silicone oil 1% is widely used. In skin care products, it gives the product a silky touch, and makes the skin feel soft and smooth when applied, enhancing the user's sensory experience. For example, some creams, after adding 1% silicone oil, can quickly form a uniform film on the surface of the skin when applied, which not only locks in the moisture of the skin, but also allows the skin to present a natural luster without affecting the normal breathing of the skin.

In industry, 1% silicone oil also has important uses. In the rubber processing process, adding this proportion of silicone oil can be used as a release agent. It can effectively reduce the friction between rubber products and molds, make the products smooth demoulding, improve production efficiency, and do not pollute the surface of the products to ensure product quality.

Second, Properties
1. ** Physical Properties **
- ** Appearance **: It generally presents a colorless and transparent oily liquid, clear and free of impurities. This property makes it easy to apply in areas with high appearance requirements such as cosmetics and medicine, and will not change the original color and transparency of the product.
- ** Viscosity **: 1% silicone oil has a suitable viscosity, which is neither too thin to cause excessive fluidity and difficult to control, nor too thick to affect its dispersion and application in the system. This moderate viscosity allows it to maintain stable performance in different product systems. For example, it can be evenly distributed on the surface of the skin in skin care products, and can be effectively attached to the surface of processed materials in industrial applications.
- ** Solubility **: Silicone oil 1% has good solubility in many organic solvents, such as ethanol, toluene and other solvents can be dissolved to form a homogeneous solution. This property is conducive to its formulation and application in different formulation systems. It can flexibly select suitable solvents according to actual needs to achieve good compatibility with other ingredients.
2. ** Chemical properties **
- ** Stability **: The chemical properties are extremely stable, and it is not easy to chemically react with other substances. Under normal temperature and pressure, even if it is placed for a long time, its chemical structure will not change significantly. This allows products containing 1% silicone oil to maintain stable performance during storage, and will not deteriorate due to reaction with substances in the environment, prolonging the shelf life of the product.
- ** Inert **: 1% silicone oil is inert and non-corrosive to most metals, plastics and other materials. In industrial applications, it can be safely contacted with equipment and products of various materials, without causing damage to equipment, ensuring long-term stable operation of production equipment, and will not affect the quality and performance of products.

Third, manufacturing (Manufacturing)
Manufacturing 1% silicone oil usually requires multiple steps. First, silicone oil with different degrees of polymerization is prepared by hydrolysis and polycondensation reaction with silicone monomer as the starting material. In this process, the reaction conditions such as temperature, pressure, catalyst type and dosage are strictly controlled to ensure that the degree of polymerization and quality of the silicone oil meet the requirements.
Next, according to the required concentration of 1%, the resulting silicone oil is accurately matched with the corresponding solvent or carrier. This process requires the use of high-precision metering equipment to ensure that the ratio of silicone oil to other ingredients is accurate. For example, in the production of cosmetics, an advanced automated ingredient system is used to accurately weigh silicone oil and other raw materials to ensure that the content of silicone oil in each batch of products is stable and consistent at 1%.
Then, the mixed materials are fully stirred and dispersed so that the silicone oil is evenly distributed in the system. Stirring speed, time, and the type of mixing equipment all have important effects on the dispersion effect. A high-speed stirrer or homogenizer is generally used to make the silicone oil evenly dispersed in the whole system as tiny particles to avoid agglomeration, thus ensuring the uniformity of product performance.

IV. USES (Uses)
In the textile industry, 1% silicone oil is often used as a softener. After the fabric is treated with a softener containing 1% silicone oil, it feels soft and smooth, and at the same time it can improve the wrinkle resistance and wear resistance of the fabric. This not only enhances the quality and added value of the fabric, but also enhances the consumer's wearing experience of the textile.
In the electronics industry, 1% silicone oil can be used as a moisture-proof and insulating coating for electronic components. It can form a dense protective film on the surface of components, effectively prevent moisture, dust and other erosion of electronic components, and at the same time provide good insulation properties to ensure the stable operation of electronic equipment and prolong its service life.
In the food industry, 1% silicone oil can be used as a defoamer. In the food processing process, such as fermentation, distillation and other links, a large amount of foam will affect the production efficiency and product quality. Adding an appropriate amount of 1% silicone oil defoamer can quickly reduce the surface tension, make the foam burst, ensure the smooth progress of the production process, and it meets the food safety standards and will not cause harm to food quality and human health.
