1. Core Basic Information

1. Product Category: Anionic surfactant (a derivative of alkylbenzene sulfonate, inheriting the core properties of the Nansa EVM series)
2. Relevant Chinese Name: Derived from the characteristics of the series products, it is presumably "high-active calcium dodecylbenzenesulfonate derivative". It belongs to the same emulsifier system as Nansa EVM 70, and the "/2E" is inferred to be a formula optimization identifier (possibly related to adjustments in active substance ratio or auxiliary components).
3. Supplier Background: Distributed by A.S Harrison (Australia), a company founded in 1923 with ISO 9001/ISO 14001 certifications. It focuses on the distribution of specialty chemical additives, covering fields such as personal care, oil and gas, and water treatment.
4. Core Functional Positioning: Primarily used as an emulsifier in agrochemical and industrial formulations. Its core role is to enhance the dispersion stability of poorly soluble active ingredients, while balancing compatibility and environmental compliance.

2. Key Technical Characteristics

1. Active Substance: Referring to the Nansa EVM 70 series standards, the active substance content is presumably approximately 70% ± 2%. The "high-active" design can reduce the amount of formulation addition and lower overall costs.
2. HLB Value Property: As an anionic surfactant, its HLB value is suitable for emulsifying non-polar active ingredients (inferred range: 10-14, meeting the requirements of agricultural emulsifiable concentrate (EC) formulations). The hydrophilic-lipophilic balance can be adjusted to achieve encapsulation and dispersion of ingredients with different polarities.
3. Temperature Adaptability: It can maintain stable emulsification performance even at a warm temperature of 60°C (this temperature parameter is clearly specified in patent formula examples), adapting to heating and stirring processes in industrial production.
4. Compatibility Advantage: It can be compounded with various solvents (e.g., NMP, benzyl acetate), other surfactants (Termul series, Terwet series), and agricultural active ingredients without obvious compatibility conflicts.

3. Typical Application Scenarios

3.1 Agrochemical Formulations (Core Scenario)

• Compatible Active Ingredients: Capable of emulsifying dinitroaniline herbicides (trifluralin, pendimethalin, etc., supporting concentrations up to 600g/L and above), pyrethroid insecticides (deltamethrin, bifenthrin, etc.), and diphenyl ether herbicides (oxyfluorfen, etc.).
• Formulation Purpose: Used to prepare stable emulsifiable concentrate (EC) formulations, solving problems such as low solubility of crystalline active ingredients and poor low-temperature stability, while extending the storage life of formulations and improving dispersion uniformity during use.
• Application Examples: An addition amount of 30g/L can achieve stable emulsification of 25g/L diflufenican; an addition amount of 21.2g/L can be compatible with a high-concentration 600g/L trifluralin formula.

3.2 Industrial Auxiliary Fields (Potential Extension)

• Based on the emulsification properties of the series products, it can be extended to formulations such as metalworking fluids, textile auxiliaries, and industrial cleaning agents. It acts as an emulsifying dispersant to enhance the compatibility between oil-phase components and water phases.
• Suitable for scenarios with high requirements for environmental compliance (presumed to meet international standards such as REACH and TSCA, and can replace traditional high-pollution emulsifiers).

4. Formula Application Key Points

1. Addition Ratio: The conventional addition amount in agricultural formulations is 20-40g/L. The specific amount needs to be adjusted according to the concentration of active ingredients and solvent system; the addition ratio can be appropriately increased for high-concentration active ingredient formulations.
2. Process Requirements: It is recommended to first mix and dissolve the active ingredients with the solvent (heating to 60°C if necessary), then add this product and stir for more than 15 minutes until the system is uniform to ensure sufficient emulsification.
3. Compounding Suggestions: It can be used in combination with non-ionic surfactants (e.g., Termul series) and dispersants (e.g., Terwet 3784) to further improve the stability and application effect of the formulation.
4. Precautions: Avoid direct contact with strongly acidic components to prevent damage to the emulsification structure; store in a sealed container to prevent moisture, and avoid high-temperature exposure (recommended storage temperature: 5-35°C).

5. Core Product Advantages

1. Performance Stability: Maintains stable emulsification effect even in high-concentration active ingredient formulations, solving the problem of insufficient loading capacity of traditional emulsifiers.
2. Broad Compatibility: Compatible with a variety of agricultural active ingredients and solvent systems, reducing the difficulty of formula adjustment.
3. Compliance Guarantee: Relying on the supplier’s comprehensive quality system, it meets international environmental standards and is suitable for the production of export-oriented products.
4. Cost-Effectiveness: The high-active formula design can reduce the addition amount per unit product, balancing performance and production costs.
