In the process of the personal care products industry, such as skincare products, sun protection products and makeup products, which are continuously developing towards a refreshing sensation, high water content and stable formulations, functional emulsifiers with excellent oil-in-water emulsifying ability and smooth skin feel are becoming the core focus in the development of water-in-silicone and oil-in-water formulation systems. The product we launched, 99336, an oil-soluble emulsifying silicone oil, with the INCI name PEG-10 polydimethylsiloxane, as a hydrophilic polyether-modified polydimethylsiloxane, demonstrates significant market value in various applications such as skincare, makeup and sun protection products, providing an efficient and high-quality emulsification solution for the personal care industry.


I. Core Physical and Chemical Properties of the Product


The product, 99336, an oil-soluble emulsifying silicone oil, is a colorless to slightly yellow transparent to semi-transparent liquid. At 25 degrees Celsius, its refractive index is 1.4100 to 1.4300, its relative density is 0.0100 to 0.0500, and its viscosity is 400 to 1600 centistokes. This product is an oil-soluble polyether polydimethylsiloxane, belonging to a non-ionic surfactant, with a slight polyether characteristic odor.


II. Core Performance Advantages of the Product


The product, 99336, with its oil-soluble polyether-modified structure, demonstrates the following core performance advantages in personal care product formulations:


Outstanding water-in-silicone and oil-in-water emulsifying ability. The product has excellent oil-in-water and silicone-in-water emulsifying performance, capable of stably dispersing a high proportion of water phase into the oil phase or silicone oil phase, forming a fine and stable emulsification system. With a low emulsifier dosage, it can achieve a high water content output effect.


Easy emulsification and low-temperature operation convenience. The product is easy to emulsify, does not require heating, and can complete emulsification operations at room temperature without the need for homogenization equipment, achieving a stable emulsion with rapid stirring, significantly reducing production energy consumption and process complexity.


Smooth and non-greasy skin feel. The product provides a smooth and non-greasy skin feel experience, effectively overcoming the possible heavy and sticky problems of traditional oil-in-water systems, enhancing the product's usage comfort and consumer acceptance.


III. Wide Application Areas


The product, 99336, with its efficient emulsifying performance and comfortable skin feel characteristics, can play a key role in the following personal care product application areas, specifically including:


1. Skincare products. In skincare formulations such as lotion, cream, essence cream and sleep mask, product 99336 can be used as the main emulsifier, constructing a stable and fine water-in-silicone or oil-in-water emulsification system, providing a refreshing and smooth skin feel experience. The recommended addition amount is 1% to 4%.


2. Makeup products. In makeup formulations such as foundation liquid, BB cream, primer and makeup primer, product 99336 can effectively emulsify and disperse the oil phase and silicone oil phase components in the formulation, forming a stable and uniform emulsification system, improving the application smoothness and hold-up effect of the product, and providing a good dispersion medium environment for pigments.


3. Sun protection products. In sun protection formulations such as sunscreen lotion, sunscreen cream and sunscreen spray, product 99336 can help stabilize the emulsification system, ensuring the uniform dispersion of sunscreen agents, improving the spreadability and water resistance of the product, and providing a refreshing and non-greasy usage experience for sun protection products.


4. Usage Methods and Process Suggestions


When using product 99336, first mix the oil phase and emulsifier evenly. Slowly pour the water phase into the oil phase and quickly stir evenly. Increasing the stirring speed can improve the stability of the water-in-oil emulsion system. Increasing the water ratio will increase the viscosity of the system. If all the raw materials are in liquid form, emulsification can be carried out at room temperature without homogenization. Just rapid stirring can result in a stable emulsion. Adding electrolyte solutions to the aqueous phase can enhance the storage stability of the emulsion system.


V. Recommended Dosage


The recommended dosage for using product hydrophobic emulsifying silicone oil 99336 as the main emulsifier is 1% to 4% of the total formula, and the recommended dosage for using it as a co-emulsifier is 0.1% to 1.5% of the total formula. The specific dosage should be determined through experiments based on the formulation system and performance requirements of the target product.


VI. Packaging Specifications and Storage Conditions


Product hydrophobic emulsifying silicone oil 99336 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.


VII. Quality Assurance and Industry Application Value


Product hydrophobic emulsifying silicone oil 99336 has established a strict quality control system during the production process. Key indicators such as product appearance, refractive index, relative density and viscosity are tested throughout the process to ensure consistency and reliability between batches.


As skincare products, makeup and sunscreen products continue to develop towards a refreshing sensation, high water content and simplified formulations, the demand for emulsifying silicone oil with efficient emulsifying ability, low-temperature operational convenience and smooth skin sensation is steadily increasing. Product hydrophobic emulsifying silicone oil 99336, with its outstanding water-in-silicone and oil-in-water emulsification performance, advantages of normal-temperature emulsification process and smooth, non-greasy skin sensation characteristics, is becoming an important emulsifier option in the development of skincare, makeup and sunscreen products, providing strong support for promoting the domestic personal care industry towards high-quality development.
