OPE-105 is a highly efficient nonionic surfactant. Its usage method needs to be flexibly adjusted according to different application scenarios. The core point is: first fully mix it with the main components of the formulation, then indirectly dilute or compound with other auxiliaries to achieve optimal dispersion, emulsification, and penetration effects.

Detailed Description

The general principle for using OPE-105 is "mix first, then dilute." Since it is a viscous liquid at room temperature, to ensure accurate measurement and rapid dispersion, it is recommended to slightly preheat it before operation (e.g., heat in a warm water bath to 30-40°C), which reduces viscosity, improves fluidity, and facilitates drum pouring and weighing. Directly adding it to a large proportion of water with rapid stirring often allows it to self-emulsify and form a working solution.

Specific usage methods vary greatly across different industries. In textile scouring and industrial cleaning, it is usually directly compounded with alkali agents, auxiliaries, etc., to form a working solution. In pesticide formulations, it is often first mixed evenly with oil-soluble technical materials as an emulsifier, then diluted in water to form a stable emulsion. In metalworking fluids, it needs to be blended with base oil, rust inhibitors, extreme pressure additives, etc., to form a concentrate, which is then diluted with water before use.

OPE-105 has good formulation compatibility and can be compounded with anionic, cationic, and other nonionic surfactants to produce synergistic effects. However, small-scale tests must be carried out during compounding to confirm no precipitation, layering, or antagonistic effects. The general addition sequence is to first mix this product with the most difficult-to-emulsify oily components, then slowly add the water phase while maintaining uniform stirring. If the water temperature exceeds its cloud point (1% aqueous solution cloud point is 65~75°C), it will form a water-insoluble emulsion. In such cases, it should be cooled below the cloud point for use to ensure complete dissolution and optimal activity.

Technical Parameters

The following are key technical indicators that need attention in the use and formulation design of OPE-105 (data source: Guoli Chemical Product Database):

Parameter Name Value Usage Guidance Significance
Appearance Colorless/Light yellow viscous liquid Can determine if the product is delaminated or deteriorated
Active Content ≥ 98.0% High effective ingredient, actual dosage should refer to formulation calculation
HLB Value 13.5 Good hydrophilicity, suitable for O/W emulsification and solubilization
Cloud Point (1% Aqueous Solution) 65 ~ 75°C Operating temperature should be below cloud point to ensure activity
pH (1% Aqueous Solution) 6.0 ~ 8.0 Moderate acidity and alkalinity, wide application range
Viscosity at 25℃ 200 ~ 400 mPa·s Preheat to reduce viscosity for easy measurement during operation
Foam Characteristics Low Foaming Suitable for spray cleaning, high-pressure cleaning, and other working conditions

Application Recommendations

According to Guoli Chemical's recommendations, typical usage methods and recommended dosages of OPE-105 in different fields are as follows:

  • Textile Scouring Penetrant: In desizing and scouring processes, compound with sodium hydroxide, chelating dispersants, etc., to form a working bath. Recommended dosage: 0.5 ~ 2.0 g/L of working solution.
  • Degreasing Cleaning Agent: When formulating industrial hard surface cleaners, mix with chelating agents and builders. Recommended dosage: 1.0 ~ 5.0% (based on total concentrate mass).
  • Pesticide Emulsifier: When preparing emulsifiable concentrates or emulsions in water, pre-stir and mix evenly with oil-soluble technical materials. Recommended dosage: 5% ~ 15% of the technical material amount (adjust based on technical material type and formulation).
  • Metalworking Lubricating Fluid: When blending cutting fluid and grinding fluid concentrates, add with other additives into base oil. Recommended dosage: 2% ~ 8% of the concentrate.
  • Leather Degreasing Agent: Used in degreasing processes of raw hides and wet-blue leather. Recommended dosage: 0.3% ~ 1.0% of pelt weight.
  • Paper Deinking Agent: Add together with sodium hydroxide, sodium silicate, hydrogen peroxide, etc., in the pulper. Recommended dosage: 0.1% ~ 0.5% of oven-dry waste paper.

Precautions

This product is an industrial chemical and is strictly prohibited for civil, food, or feed industries. Please strictly follow the following operating specifications during use:

  • Personal Protection: Wear qualified nitrile rubber gloves, chemical protective clothing, and safety goggles during operation. Avoid inhaling vapors or mists, especially when heating. Replace protective equipment immediately if contaminated.
  • On-site Management: Keep the workplace well-ventilated. Do not eat or smoke at the operation site. Wash exposed skin thoroughly with soap and water after work.
  • Operating Conditions: Do not add this product into boiling water; slowly add it into warm water while stirring to dissolve. Follow the "add in small amounts multiple times" principle and regularly check the transparency and uniformity of the system.
  • First Aid Knowledge: If it accidentally enters the eyes (can cause severe eye damage), immediately rinse with plenty of water for at least 15 minutes and seek medical attention immediately. In case of skin contact, immediately remove contaminated clothing and wash with soapy water. If ingested, do not induce vomiting; seek medical attention immediately.
  • Environmental Requirements: This product is toxic to aquatic organisms with long-lasting effects. Do not discharge waste liquid or rinse water directly into sewers, surface water, or soil. Must be handed over to qualified companies for waste disposal.
