The usage methods of Oleth-10 (Oleyl Alcohol Polyoxyethylene Ether OV-10) mainly include its use as an O/W emulsifier, wetting agent, and dispersant, widely applied in personal care, industrial cleaning, textile printing and dyeing, pesticide formulations, metalworking fluids, and leather processing industries.
Detailed Description
Oleth-10 (CAS: 9004-98-2) is a high-efficiency nonionic surfactant produced by Guoli Chemical. It appears as a light yellow transparent liquid with excellent acid-alkali resistance and formulation compatibility. Its HLB value is approximately 12.4, enabling outstanding performance in forming oil-in-water (O/W) emulsions. In practical applications, the recommended dosage is typically 1.0% to 10.0% of the total formulation, and the specific ratio should be adjusted based on the performance requirements of the final product and other components in the formulation. For example, when used as an emulsifier, the addition amount is usually between 2.0% and 5.0%; when used as a wetting agent or penetrating agent, the addition amount can be as low as about 0.5%.
During use, Oleth-10 can be directly added to the water phase and stirred for dispersion, or it can be pre-mixed with the oil phase if necessary. This product has a high cloud point (65~80°C), low foam, and excellent foam control properties, making it especially suitable for applications such as industrial cleaning and metalworking fluids that require low foam and high efficiency. It maintains interfacial activity over a wide process temperature range and exhibits excellent emulsification and penetration capabilities.

Application Recommendations
Based on the database information and practical experience of Guoli Chemical products, the specific usage methods in different fields are suggested as follows:
- Personal Care Products (Creams/Lotions): At 75-80°C, mix OV-10 with the oil phase components, while heating the water phase. Then slowly add the oil phase to the water phase with uniform stirring and emulsification, followed by homogenization and cooling. Recommended dosage: 2.0-6.0% of the total formulation.
- Industrial and Household Cleaners: Add directly to water with stirring to dissolve, utilizing its low-foam wetting properties to treat hard surface grease or reusable fabrics. Recommended dosage: 1.0-5.0% of active concentration.
- Textile Printing and Dyeing: As a leveling agent or dispersant, pre-mix the dye with this product in a mixing tank, then slowly add to the pretreatment bath. For high melting point dyes, heating to 50-60°C may be appropriate. Recommended dosage is typically 0.5-2.0% of the fabric weight.
- Pesticide Emulsion in Water (EW): Mix this emulsifier with oily active ingredients and solvent to form an oil phase, then slowly add to the water phase (including antifreeze and other additives) and emulsify using a high-shear emulsifier. Recommended dosage: 5.0-8.0% of the total formulation.
- Metalworking and Degreasing: When formulating semi-synthetic microemulsion cutting fluids, mix it with base oil, rust inhibitor, extreme pressure agent, etc., then add water to spontaneously form a stable working fluid. It can also be used directly in leather degreasing processes by diluting with 25 to 50 times cold water.
Precautions
This product is classified as a chemical (signal word: Warning). Strictly follow safety regulations during handling:
- Personnel Protection: To avoid skin irritation (H315) or serious eye irritation (H319), wear qualified nitrile rubber gloves and protective goggles before use; avoid eating or drinking while using.
- Storage Suggestion: Keep the packaging drum tightly sealed after use, and store in a dry, cool place (recommended storage temperature 5°C–35°C). The product has a low pour point (< -5°C). If it solidifies, it can be thawed at room temperature and stirred evenly before use, without affecting performance.
- First Aid Measures: In case of skin contact, immediately remove contaminated clothing and wash thoroughly with plenty of running water and soap. If in eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical attention.
