Solubilizer S-15 (CAS No.: 39464-69-2), with the chemical name PEG-40 Hydrogenated Castor Oil, is a high-efficiency nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. Its unique molecular structure, derived from natural hydrogenated castor oil derivatives, endows the product with outstanding solubilizing, emulsifying, and wetting abilities. This product can significantly reduce the surface tension of aqueous solutions, uniformly and stably dispersing poorly soluble substances such as fragrances, essential oils, and oil-soluble active ingredients into water-based systems, forming clear and transparent solutions or stable emulsions.
Solubilizer S-15 exhibits excellent stability in acidic, alkaline, and hard water environments, maintaining chemical stability across a wide pH range and under high-temperature conditions. Additionally, it has good water and alcohol solubility and can be flexibly compounded with various anionic, cationic, and other nonionic surfactants. Environmentally, the product has low aquatic toxicity and is readily biodegradable (with a 28-day degradation rate >60% under OECD 301B standard), meeting the requirements of modern green chemicals.
1. Agrochemical Formulations: Used as a solubilizer and emulsifier in emulsifiable concentrates (EC), oil-in-water emulsions (EW), and microemulsions (ME), effectively solubilizing pesticide active ingredients, promoting the formation of stable and transparent microemulsion systems or homogeneous emulsions, enhancing dispersion and dilution stability in hard water, and improving efficacy.
2. Personal Care and Daily Chemicals: Used in water-based transparent products such as clear shampoos, shower gels, and toners to effectively solubilize fragrances, natural essential oils, and oil-soluble skin care active ingredients, maintaining product clarity and preventing turbidity and phase separation.
3. Industrial Hard Surface Cleaning: In cleaning formulations, it rapidly solubilizes and emulsifies heavy grease, mineral oils, and hydrophobic organic soils, significantly improving the penetration, detachment, and anti-redeposition properties of the cleaner, especially suitable for industrial hard surface cleaning of vehicles and machinery.
4. Textile Printing and Dyeing: Acts as a leveling agent and dispersing auxiliary, solubilizing and dispersing dyes, leveling agents, and other functional finishing agents, promoting uniform adsorption of dyes on fiber surfaces, preventing color defects, and improving colorfastness and fabric appearance.
