1. Gel water and hair styling products. Product water-soluble silicone oil 9939 is particularly suitable for gel water and hair styling products. In the gel water formulation, this product is usually compounded with high-molecular-forming materials such as polyethylene polyamine to form a transparent product, providing softness and brightness, allowing the hairstyle to remain natural and shiny without stiffness, and giving hair a smooth touch.


2. Facial cleansers and cleansing products. In facial cleansers and cleansing foam products, product water-soluble silicone oil 9939 can be used as a mild conditioner and foam stabilizer, giving the skin a soft and non-tightening feeling after cleansing, while its excellent water solubility ensures easy rinsing without residue. The recommended addition amount is 1% to 3%.


3. Cream-type skin care products. In skin care lotions, creams, and essences, product water-soluble silicone oil 9939 can be used as a hydrophilic moisturizer and emulsifying aid, improving the spreadability and skin sensation of the formula, making the product smooth and non-greasy after application, and having good moisturizing and breathable effects. The recommended addition amount is 1% to 3%.


4. Stable foam agent for aerosol products. Product water-soluble silicone oil 9939 is also suitable for stabilizing foaming agents in aerosol products, helping to produce fine and uniform foam structures, and enhancing the user experience and visual effect of the product.


5. Plasticizer for organic resins. In hair styling products, this product can also be used as a plasticizer for organic resins, improving the flexibility and gloss of the film-forming resins and avoiding stiff or brittle hair after styling.


4. Usage suggestions and recommended dosage


Product water-soluble silicone oil 9939, due to its excellent surface activity and water solubility, is easy to use and can be directly added to the aqueous or oil phase components. In gel water formulas, it is usually compounded with film-forming polymer materials to form transparent products. In shampoo and cream-type products, the recommended dosage is typically 1% to 3%. The recommended dosage of this product is 1% to 3%, and the specific addition amount should be determined through experiments based on the formulation system and performance requirements of the target product.


5. Packaging specifications and storage conditions


Product water-soluble silicone oil 9939 is packaged in 25-kilogram plastic drums or 200-kilogram iron drums. This product is non-hazardous. During transportation and storage, it is necessary to prevent the intrusion of moisture, acids, alkalis, and other impurities, and avoid direct sunlight and rain. The container should be strictly sealed after each use. Under the condition of meeting the above storage conditions and without opening, the shelf life of this product is two years.


6. Quality assurance and industry application value


Product water-soluble silicone oil 9939 has established a strict quality control system during the production process. It conducts full-process detection of key indicators such as product appearance, viscosity, refractive index, relative density, and cloud point to ensure consistency and reliability between batches.


As the personal care product industry, including hair care, skin care, and styling products, continues to develop towards water-based, transparent, and efficacy-oriented directions, the demand for hydrophilic silicone oil raw materials with excellent water solubility, mild conditioning properties, and good foam stability is steadily increasing. Product water-soluble silicone oil 9939, with its polyether-modified silicone oil structure advantages, excellent water solubility that mixes with water in any proportion, and wide application compatibility in formulations, is becoming an important raw material option for the development of gel water, shampoo, cream, and aerosol products, providing strong support for promoting the domestic personal care product industry towards higher quality and refinement.
