Stearyl Polyoxyethylene Ether SG-6 (chemical name: Polyoxyethylene (6) Stearate, CAS No.: 9004-99-3), with its precise hydrophilic-lipophilic balance molecular structure, demonstrates excellent application value in multiple industrial fields. The product appears as a white to slightly yellow waxy solid or flake, dispersible or soluble in water, and soluble in organic solvents such as ethanol. It exhibits outstanding formulation compatibility and can be synergistically compounded with anionic, cationic, and amphoteric surfactants.
Its core functional advantages are reflected in four aspects: First, an extremely low critical micelle concentration provides excellent emulsifying power, efficiently emulsifying various animal and vegetable oils and mineral oils; second, outstanding dynamic surface tension reduction capability gives instant wetting and spreading effects on fibers and hard surfaces; third, it remains stable in acidic, alkaline, and hard water conditions without saponification or hydrolysis; fourth, it is broadly compatible with various ionic surfactants, providing synergistic effects without antagonism.
In terms of ecological safety, this product is classified as low toxicity (rat oral LD50 > 2000 mg/kg), non-irritating to skin, and readily biodegradable (28-day biodegradation rate > 60%), aligning with the trend toward green chemistry.
| Application Industry | Specific Process/Use | Functional Role |
|---|---|---|
| Cosmetics Industry | Cream, lotion, and other skincare product systems | Acts as an efficient emulsifying and solubilizing agent, stabilizing oil-water two-phase systems, imparting a fine texture and light skin feel to products; also serves as a solubilizer for fragrances and fat-soluble active ingredients |
| Textile Printing and Dyeing | Finishing processes (softening finishing, antistatic finishing) | Adsorbs onto fiber surfaces, imparting soft and fluffy handfeel to fabrics; reduces surface resistance of fibers, eliminates static buildup, and enhances wearing comfort |
| Pesticide Formulations | Water-based pesticide formulations (emulsifiable concentrates, emulsions, etc.) | Stably disperses pesticide active ingredients in water to form a uniform emulsion, improving the wetting and spreading ability of the spray liquid on plant leaf surfaces, enhancing efficacy and reducing active ingredient loss |
| Industrial Cleaning | Metal degreasing, precision cleaning, hard surface cleaning | Provides excellent detergency and degreasing capabilities, rapidly penetrating and emulsifying oil and grease on metal surfaces and equipment |
| Metalworking Fluids | Formulation of cutting fluids, grinding fluids, etc. | Acts as an emulsifying and lubricating component, forming an effective lubricating film on metal surfaces, reducing processing friction and heat, while also providing cooling, rust prevention, and extreme pressure auxiliary performance |
| Papermaking Industry | Deinking process in waste paper recycling | Effectively strips and disperses printing ink particles, preventing ink redeposition on fiber surfaces, improving the brightness and cleanliness of recycled pulp |
The usage method and addition amount of this product vary across different processes: in cosmetic cream systems, it is typically added to the oil phase as a primary or auxiliary emulsifier; in textile softening finishing, it is generally formulated into a working solution and applied to fabrics via padding or dipping processes; in pesticide formulations, it is used as an emulsifier component in combination with other surfactants; in industrial cleaning and metalworking fluids, it is added directly according to formulation requirements. The specific dosage should be determined through experiments based on the actual formulation system and process requirements.
