In the formulation design of personal care products such as skin care products, cosmetics, and sunscreen products, the sensory experience and the efficacy of active ingredients are often the core indicators for evaluating the quality of the products. The composite silicone oil raw material with high film-forming property, excellent spreading property, and active ingredient affinity is becoming an important tool for formulators to achieve a balance between sensory experience and efficacy. The product 1403, a blend of polydimethylsiloxane and polydimethylsiloxane alcohol, introduced by our company, is a composite solution of ultra-high viscosity polydimethylsiloxane alcohol dissolved in low viscosity polydimethylsiloxane. With its comprehensive performance such as enhancing the affinity of active ingredients, improving the spreading property, and providing a smooth sensory experience, it demonstrates significant application value in various personal care products such as hand and body lotion, cosmetics, sunscreen, moisturizing cream, and body wash.


I. Core Physical and Chemical Properties of the Product


The product polydimethylsiloxane and polydimethylsiloxane alcohol blend 1403 is a transparent liquid with an organic silicon content of no less than 99%. The content of silicone gel (polydimethylsiloxane alcohol) is 12% to 14%, and the viscosity at 25 degrees Celsius is 4,000 square millimeters per second. The closed-cup flash point is 135 degrees Celsius, the specific gravity is 0.93, and its solubility in water is less than 0.1%. The product is a blend of high-viscosity polydimethylsiloxane alcohol and low-viscosity polydimethylsiloxane, through the synergistic effect of the two, it retains the excellent film-forming property and smooth touch of high-molecular-weight polydimethylsiloxane alcohol, and achieves good processing fluidity and spreading property by leveraging the carrier effect of low-viscosity polydimethylsiloxane. The D4 ring body content of less than 2% meets the strict requirements of the personal care industry for ring body residue, providing reliable guarantee for the safety of the formulation.


II. Core Performance Advantages


The product polydimethylsiloxane and polydimethylsiloxane alcohol blend 1403, with its unique composite structure, exhibits the following core performance advantages in personal care product formulations:


Enhancing the affinity and persistence of active ingredients. The high-molecular-weight polydimethylsiloxane alcohol in the product can form a uniform and breathable protective film on the skin surface, which helps improve the adhesion and persistence of other active ingredients on the skin, allowing moisturizing, sun protection, and nourishing ingredients to function for a longer time.


Excellent spreading property and smooth sensory experience. The low-viscosity polydimethylsiloxane acts as a carrier, providing the product with excellent spreading property and smooth application feel, making creams and lotions easy to spread on the skin, and bringing a smooth, non-greasy sensory experience. It forms an anti-water and breathable film on the skin, achieving water retention and moisturization while not blocking pores, maintaining the natural breathing of the skin.


III. Wide Application Areas


The product polydimethylsiloxane and polydimethylsiloxane alcohol blend 1403, with its multi-functional performance combination, can play a key role in the following personal care product application areas, including:


1. Hand and body lotion. In hand cream and body lotion, the product can effectively improve the formulation's extensibility and sensory experience, giving the skin a soft and smooth touch, and helping other moisturizing and nourishing ingredients to remain on the skin for a longer time.


2. Cosmetics. In cosmetic formulations such as foundation liquid, primer, and makeup base, the product can enhance the smoothness and adhesion of the formulation, helping color powder to be evenly dispersed, making the makeup more natural and flawless.


3. Sunscreen products. In sunscreen and sunscreen lotion, the product can form a uniform protective film on the skin surface, helping the sunscreen agent to be evenly covered, and providing a light and non-greasy usage experience.


4. Moisturizing cream and lotion. In various moisturizing cream and emollient lotion formulations, the product can synergistically enhance the moisturizing effect and sensory experience of the formulation, making the product form a moisturizing but non-greasy sensory experience, improving the comfort of use.


IV. Usage Suggestions and Process Guidance


When using the product copolymer 1403 of polydimethylsiloxane and polydimethylsiloxane alcohol in the formula, it is recommended to use a high-speed stirrer. After the cream emulsification is completed, use a homogenizer to process it to obtain a uniform and fine cream texture to ensure that the product is fully dispersed in the formula and performs at its best.


V. Packaging Specifications and Storage Conditions


The product should be stored in the original unopened container at a temperature of 25 degrees Celsius or lower. This product shall not be used for human injection and must not be used for consumption. It has not been tested and is not explicitly declared to be suitable for medical or pharmaceutical uses.


VI. Quality Assurance and Industry Application Value


The product copolymer 1403 of polydimethylsiloxane and polydimethylsiloxane alcohol has established a strict quality control system during production. Key indicators such as the organic silicon content, silica content, viscosity, flash point, and D4 ring body content of the product are monitored throughout the process to ensure consistency and reliability between batches. As the personal care product industry continues to develop towards refined skin feel and long-lasting efficacy, the demand for composite silicone oil raw materials with dual functions of film-forming conditioning and spreading enhancing has been steadily increasing. The product copolymer 1403, with its synergistic combination of high-viscosity silica and low-viscosity silicone oil, is becoming an important functional raw material option in the development of skin care, makeup, and sunscreen products, providing strong support for promoting the quality upgrade and formula innovation of the domestic personal care product industry.
