Peregal O-15 is a high-performance nonionic surfactant, featuring excellent emulsifying ability, outstanding wetting and spreading properties, broad compatibility with other ingredients, and high-purity active content. It is an ideal multifunctional auxiliary for industries such as textiles, cleaning, cosmetics, and pesticides.
Detailed Description
Peregal O-15 (fatty alcohol polyoxyethylene (15) ether, CAS No.: 68439-49-6) is a classic nonionic surfactant produced by Guoli Chemical. Its molecular structure is formed by adding long-chain fatty alcohol to 15 ethylene oxide units, endowing the product with excellent oil-in-water (O/W) emulsifying performance. It effectively stabilizes emulsion systems, resulting in products with a fine and uniform texture, making it an ideal emulsifier for creams, lotions, cosmetics, and pesticide emulsifiable concentrates.
This product has excellent wetting and spreading properties, significantly reducing the surface tension of liquids and quickly spreading and penetrating on substrates such as fabrics, metals, and leather. It also demonstrates broad chemical compatibility — good resistance to acids, alkalis, and hard water, and can be effectively compounded with nonionic, anionic, cationic, and amphoteric auxiliaries, greatly enhancing formulation flexibility. The product appears as white to slightly yellowish flakes or paste, a physical form convenient for storage, transportation, and precise dosing, with high solid content and a clear cost-performance advantage.
In terms of safety, this product is a low-toxicity chemical (LD50>2000mg/kg), but direct contact may cause skin and eye irritation (GHS classification: Skin Irritation Category 2, Serious Eye Damage Category 2A). Protective equipment should be worn during handling. It also has long-lasting adverse effects on aquatic life, and release into water bodies must be strictly prevented.

Application Recommendations
Peregal O-15 is widely used in the following fields:
- Textile Printing and Dyeing: As a leveling agent and emulsifier, it promotes uniform dye uptake during dyeing to prevent color irregularities and spots. It is also used in pre-treatment and post-finishing emulsification and dispersion processes.
- Industrial Cleaning: As a core raw material for degreasers, it has strong emulsifying and removing ability for mineral oils, animal and vegetable fats, making it suitable for medium-to-high temperature cleaning of hard surfaces, such as metal processing and machinery.
- Daily Chemical Products: As an O/W emulsifier for the preparation of creams, lotions, sunscreens, and skincare products. It can also be used to solubilize fragrances and essential oils, improving product clarity and stability.
- Pesticide Formulations: As an emulsifier in emulsifiable concentrates and aqueous emulsions, it improves spontaneous emulsification and dispersion of the pesticide liquid, enhancing efficacy.
- Leather Processing: Used in soaking and degreasing stages to accelerate hide wetting, softening, and emulsification removal of natural fats.
- Paper Industry: As a rewetting agent, it improves the surface hydrophilicity and soft feel of tissue paper, napkins, and other products.
- Coatings and Inks: As a wetting and dispersing aid for pigments and fillers, it reduces system surface tension and prevents floating, flooding, and sedimentation.
Precautions
- Wear protective gloves, goggles, and protective clothing during handling to avoid direct contact with skin and eyes.
- In case of accidental eye contact, immediately rinse with running water for at least 15 minutes. Remove contact lenses if present and continue rinsing. If irritation persists, seek medical attention.
- Use in a well-ventilated area and avoid inhaling vapors or aerosols.
- Do not discharge the product into sewers or water bodies to prevent long-term harm to aquatic organisms.
- Store in a cool, dry, well-ventilated place, keep containers tightly closed, and away from fire, heat sources, oxidizing agents, strong acids, and alkalis.
- In case of a spill, collect with sand or inert absorbent material and dispose of according to local regulations.
