Product Description

Propylene Glycol Block Polyether L31(CAS 9003-11-6): Overview

Propylene glycol block polyether L31 (CAS 9003-11-6) is a non-ionic EO-PO block copolymer, widely used as a surfactant in industrial applications. It features low foam, good water solubility, and high chemical stability. Key functions include emulsification, wetting, and dispersion, making it suitable for pesticide formulations, coatings, detergents, and textile auxiliaries. With low toxicity and compatibility with various systems, it's a versatile industrial-grade additive for improving product performance in agrochemical, cleaning, and manufacturing sectors.

Product Advantage

Outstanding Low-Foam Performance
With an HLB value of 3.5, L31 maintains minimal foam during application—critical for high-efficiency processes like textile dyeing or industrial cleaning. Its stable foam control reduces post-treatment steps, boosting operational efficiency by ~20% in mass production.
High Compatibility & Stability
It works well with acidic, alkaline, and neutral systems, with a pH range of 5.0–7.0 and water content ≤1.0% (meeting industrial-grade standards). This ensures consistent performance in diverse formulations, reducing material waste by 15% in long-term storage.
Efficient Emulsification & Wetting
As a non-ionic surfactant, it quickly disperses and emulsifies insoluble substances (e.g., pesticide active ingredients). Its active matter ≥70% guarantees strong wetting ability, improving the coverage rate of agrochemical sprays by ~25%

Product Uses

Textile Auxiliary
Used in textile dyeing and finishing processes as a leveling agent, it prevents uneven dyeing and enhances color uniformity. It's also blended into high-efficiency synthetic detergents for textiles, improving cleaning effectiveness while reducing fiber damage.
Agrochemical Formulation
Acts as an emulsifier in pesticide formulations, helping disperse active ingredients evenly. This improves the adhesion of pesticides on crop surfaces, enhancing pest control efficiency without causing phytotoxicity.
Industrial Cleaning
Applied in industrial cleaning agents, its low-foam and wetting properties enable deep cleaning of machinery or equipment surfaces, especially in environments where foam buildup would hinder operations.

Product Operate Guide

For most applications (e.g., pesticide emulsification), dilute L31 with water at a ratio of 1:5–1:10 (adjust based on specific formulation requirements). Stir evenly before mixing with other ingredients. For textile use, add it directly to the dye bath at 0.5–1.0% of the fabric weight, then proceed with standard dyeing procedures.

FAQ

What is the shelf life of L31?
When stored in a cool, dry, and ventilated place (avoiding direct sunlight), its shelf life is 12 months. Ensure the package is sealed after each use to prevent moisture absorption.
Is L31 compatible with other surfactants?
Yes, it can be mixed with most non-ionic, anionic, or cationic surfactants. Test a small sample first to confirm compatibility for specific formulations.
Can L31 be used in food-related applications?
No, L31 is an industrial-grade product and is not suitable for food, pharmaceutical, or cosmetic applications. It is intended for industrial sectors like textiles, agrochemicals, and cleaning.
