The chemical name of solubilizer S-15 is PEG-40 Hydrogenated Castor Oil (CAS number: 39464-69-2), which belongs to nonionic surfactants. It is produced by the ethoxylation reaction of natural hydrogenated castor oil with approximately 40 ethylene oxide (EO) molecules. The "40" represents the average degree of ethoxylation, which determines the hydrophilic-lipophilic balance characteristics of the product, giving it excellent solubility and solubilizing performance in water.
In terms of molecular structure, PEG-40 Hydrogenated Castor Oil uses the fatty chain of hydrogenated castor oil (mainly triglycerides of 12-hydroxystearic acid) as the hydrophobic group and the polyoxyethylene chain (PEG chain) as the hydrophilic group. This unique structural design enables it to form micelles in aqueous solutions, encapsulating oil-soluble substances (such as fragrances, essential oils, pesticide active ingredients, etc.) inside the micelles, thereby achieving solubilization and emulsification functions. This product is purely nonionic and does not contain any anionic or cationic active ingredients.
As an important product of Guoli Chemical's solubilizer series, S-15 is derived from natural renewable raw material hydrogenated castor oil. It has low aquatic toxicity and is easily biodegradable (degradation rate >60% under OECD 301B standard within 28 days), meeting the environmental requirements of modern green chemicals.
