The product forms a uniform and breathable protective film on the skin or hair surface, which helps enhance the attachment and persistence of active ingredients such as sunscreen agents and moisturizers in the formula, while providing a velvety smooth skin sensation and effectively reducing the greasiness of the oily formula.


Excellent formulation compatibility. The product has good compatibility with various cosmetic raw materials, including hydrocarbons, mineral oils, isomeric dodecanes, various vegetable oils, esters, sunscreen agents and various organic silicone raw materials, providing extensive compatibility space for formula design.


Easy processability. The product can be added to emulsion systems at temperatures below 60 degrees Celsius through homogenization or high-speed stirring, or directly added to the oil phase of non-emulsion products, with convenient operation.


III. Wide Application Areas


The product cyclopentasiloxane and polydimethylsiloxane alcohol blend 1021 and 1022, with their high film-forming ability and excellent skin feel, can play a key role in the following personal care product application areas, specifically including:


1. Skincare lotions and creams. In various skincare lotions, creams and essence products, the product can enhance the moisturizing effect and skin sensation experience of the formula, giving the product a velvet-like smooth texture, reducing greasiness, and is recommended for essence, moisturizing creams, etc.


2. Sunscreen products. The product can be used to prepare sunscreen lotions with good application characteristics and water resistance, enhancing the attachment and persistence of sunscreen agents on the skin surface, and improving the sunscreen effect.


3. Makeup products. In foundation liquids, primer and tinted moisturizers and other makeup formulas, the product can enhance the applicability and hold-up effect of the makeup, providing a smooth and silky application experience.


4. Hair care products. The product provides silky texture and moisturizing effect for hair care serums and repair essences, improving the manageability and health appearance of hair.


IV. Usage Suggestions and Process Guidance


The product is suitable for both emulsion and non-emulsion formula systems. In emulsion products, it should be added to the system at temperatures below 60 degrees Celsius through homogenization or high-speed stirring; in non-emulsion products, it can be directly added to the oil phase. The suitable storage conditions are to store it in an environment above the freezing point. If the product solidifies, under no circumstances should an open flame be used to melt it.


V. Packaging Specifications and Storage and Transportation Conditions


The product is available in two packaging specifications: 200-liter iron drums (net weight 190 kilograms) and 950-kilogram IBC packaging. The product should be stored in the original sealed container at a temperature below 25 degrees Celsius. The standard validity period is two years from the production date.


VI. Quality Assurance and Industry Application Value


The product, the copolymer of cyclosiloxane and polydimethylsiloxane alcohol 1021 and 1022, has established a strict quality control system during production. Key indicators such as product appearance, color, odor, viscosity, non-volatile matter content, specific gravity, D4 content, flash point, refractive index, and heavy metal content are monitored throughout the process to ensure consistency and reliability between batches.


As the personal care product industry continues to develop towards long-lasting makeup retention, long-lasting moisture retention, and refreshing skin sensation, the demand for composite silicone oil raw materials with high film-forming properties and light skin feel is steadily increasing. The product cyclosiloxane and polydimethylsiloxane alcohol copolymer 1021 and 1022, with its dual specification selection design, excellent formulation compatibility, and unique skin sensation experience, is becoming an important functional raw material option in the development of skincare, sun protection, makeup, and hair care products, providing strong support for promoting the quality upgrade and formula innovation of the domestic personal care product industry.
