Emulsifiers for Oil Dispersion Formulations

Choose an emulsifier for an oil dispersion by identifying the carrier oil and active ingredient first. DO 01 and DO 02 have distinct documented starting points: vegetable oil and methyl oleate. A grade recommendation still requires testing in the complete formulation and its dilution water.

Vegetable oil: DO 01

DO 01 agricultural oil emulsifier is described for vegetable-oil-based OD formulations. The published table lists a liquid appearance at 20°C, HLB 6.9 and content of at least 99%. Use the carrier identity, oil specification, active ingredient and target loading to begin the technical review.

Methyl oleate: DO 02

DO 02 methyl oleate emulsifier is described for methyl oleate and OD formulations. Its published table lists a liquid appearance at 20°C, HLB 11.5 and content of at least 99%. These values describe the supplied material; they are not a confirmed emulsifier ratio or proof that every methyl-oleate formulation will be stable.

Keep other emulsifier applications distinct

DO 03 is described for propanil formulations including EC, EW, SE and ME. Other emulsifier grades require a separate technical review. The documented uses do not establish DO 03 as a universal substitute for DO 01 or DO 02 in OD. Ask for a technical review before changing the active ingredient, carrier or dosage form.

Information needed for a trial recommendation

• Identify the carrier oil, its specification, the active ingredient, its loading and the other formulation ingredients.
• Provide manufacturing temperature, dispersion or milling conditions, dilution ratio, water hardness and dilution temperature.
• Request the starting emulsifier level, any co-emulsifier requirement and addition order. Specify whether the dosage is based on the total formulation, oil phase or another agreed basis.
• Agree the test method and acceptance criteria for concentrate stability, particle settling, redispersibility, emulsion separation after dilution, foam and storage performance.
• Record the water composition, dilution procedure, observation times and temperature for each test. Compare samples under the same conditions before deciding between grades.

Product documents and samples

Read the product-specific Chinese TDS linked on the DO 01 and DO 02 pages or in technical downloads. To request English documentation, a separate SDS and evaluation samples, contact the technical team with the model, carrier oil, active ingredient and target market. A numerical production dosage should be confirmed for the actual formulation.

OD comparison record: carrier and dilution conditions

• Identify the vegetable oil for DO 01 or methyl oleate for DO 02 by specification and batch. Record active ingredient, loading, water/oil content and other emulsifiers.
• Record actual additive mass and denominator, order of addition, temperature, mixing and milling conditions. HLB values alone are not a blending recipe.
• Use the same dilution ratio, water hardness/composition, temperature, mixing procedure and observation times; record separation, sediment, redispersion and foam.
• Define untreated or existing-package controls, repeat samples, sealed containers, storage schedule and acceptance criteria before the comparison.

This is a proposed record template, not a test report or a production recommendation. Agree numerical doses, conditions and acceptance limits before testing. Publish an outcome only with actual results, method, conditions and an approved report reference.
