Oleth-10 is a light yellow transparent liquid that is easily soluble in water, with a cloud point of 65~80°C and a surface tension of 28~32 mN/m. Due to its strong hydrophilicity (HLB about 12.4), it is recommended to add it to the water phase for dissolution and dispersion in formulations. Alternatively, depending on process requirements, it can be heated with the oil phase to 40~60°C before mixing and emulsification. This product disperses well in water at room temperature, and heating helps improve dissolution speed and emulsification uniformity.
In practical operation, it is recommended to slowly add this product to the main phase of the formulation under stirring conditions, using medium to high-speed stirring (500~1500 rpm) for 10~30 minutes until the system is uniform and transparent or forms a stable emulsion. For high-viscosity products like creams, a homogenization emulsification process is recommended to achieve finer droplet sizes and better long-term stability. This product is chemically stable and maintains activity in acidic, alkaline, and hard water conditions, but should be kept away from strong oxidizing agents.
The following addition amounts are general industrial reference ranges (Data source: industry application experience, Guoli Chemical Database does not have these specific values), and it is recommended to start with small dosages and optimize stepwise:
| Application Field | Specific Use | Recommended Addition Amount (% of total formula weight) |
|---|---|---|
| Personal Care | Creams/Lotions (O/W primary emulsifier) | 1.0%~5.0% |
| Personal Care | Cleansing Oils/Cleansing Waters | 3.0%~8.0% |
| Personal Care | Shower Gels/Cleansing Products (solubilization and refatting) | 1.0%~4.0% |
| Household & Industrial Cleaning | Hard Surface Cleaners/Fabric Detergents | 1.0%~5.0% |
| Textile Dyeing & Printing | High-Temperature Leveling Agents | 0.5~3.0 g/L (working solution) |
| Agrochemical Formulations | Emulsion in Water (EW)/Microemulsion (ME) | 3.0%~8.0% |
| Metalworking Fluids | Emulsifiable/Semi-Synthetic Cutting Fluids | 5.0%~15.0% |
| Leather Processing | Degreasing Agents/Fatting Agent Components | 0.5%~2.0% |
Personal Care: In O/W creams and lotions, OV-10 can be used alone or compounded with low-HLB emulsifiers (such as OV-2, OV-5, etc.) to achieve a wider emulsification range and a denser interfacial film. For makeup remover products, leveraging its excellent solubilization ability and mildness, it can provide a good "wet-hand makeup removal" experience. It is recommended to be used with thickeners and stabilizers like Carbomer or Xanthan Gum to further improve the long-term stability of the emulsion.
Industrial Formulations: In metalworking fluids and agrochemical formulations, OV-10 not only provides excellent emulsifying properties but also functions in boundary lubrication and foliar spreading. It is recommended to compound it with anionic surfactants (such as sulfonates) to form a synergistic composite emulsification system, reducing the total surfactant dosage while improving emulsion stability.
