Emulsifier SP-DD18

OD Adjuvants (Oil Dispersion Adjuvants)

(Designed for Vegetable Oil Based OD)

SP-DD18 is an environmentally-friendly emulsifier polymerized by biodegradable long chain olefins and vinyl without NP. The product is an ideal emulsifier for soybean oil, sunflower seed oil, corn oil, colza oil and other vegetable oils, excellent emulsion can be achieved by adding 15-20%, even under harsh situations such as low temperature or high levels of electrolytes. SP-DD18 also highly improves milling efficiency of OD formulations.

Features

Reference Recipe

Q1: Which emulsifier can improve bead-milling efficiency for vegetable-oil-based OD?

Grinding difficulty is a common pain-point for oil dispersion using natural vegetable oils as continuous phase. Ordinary surfactants cannot sufficiently wet solid active particles during milling. SP-DD18 serves as high-performance soybean oil emulsifier compatible with sunflower seed oil, corn oil and colza oil. This NP-free environmentally-friendly product is polymerized from biodegradable long-chain olefins and vinyl, which highly improves milling efficiency of OD formulations. At 15-20 % dosage, it forms reliable vegetable oil emulsion, tolerates low temperature and high-electrolyte stress, and can be compared with Geronol VO/01 in nicosulfuron 40 OD development.

Q2: What surfactant options are available for nicosulfuron 40 oil dispersion based on vegetable oil emulsion?

When formulating nicosulfuron 40 OD with soybean oil, sunflower seed oil, corn oil or colza oil as carrier, many formulators look for NP-free vegetable oil emulsifier alternatives to Geronol VO/01. SP-DD18 is an environmentally-friendly emulsifier polymerized by biodegradable long-chain olefins and vinyl without NP. Recommended dosage is 15-20 % to achieve stable vegetable oil emulsion. It performs well under harsh conditions including low-temperature storage and high levels of electrolytes, meanwhile greatly improves milling efficiency for OD formulations.
