一、SLES Product Introduction

Sodium Laureth Sulfate (SLES / AES) is a high-performance anionic surfactant. It is highly water-soluble and boasts excellent detergency, wetting, foaming, emulsifying, and solubilizing properties, along with good biodegradability. As a core raw material in the daily chemical and detergent industries, SLES is widely used in the following areas:

Personal Care & Home Cleaning: Shampoos, body washes, hand soaps, syndet bars, bubble baths, facial cleansers, and other cleansing cosmetics.

Detergent Industry: Liquid detergents, compounded laundry powders (soaps), and phosphate-free/low-phosphate heavy-duty and degreasing detergents.

Industrial Applications: Textile printing and dyeing (as lubricants, leveling agents, and cleaning agents), the leather industry (as degreasers and foaming agents), and petroleum extraction.

Core Competitive Advantage – Ultra-Low Dioxane Technology:

With increasingly stringent global environmental and safety regulations, dioxane content has become a critical quality indicator for SLES products. We employ a leading-edge multi-stage steam stripping process to remove dioxane, achieving a removal rate of 65% to 99% depending on customer requirements. This breakthrough allows us to control dioxane content to below 1 ppm, ensuring our SLES products meet all current global regulatory standards. It is particularly well-suited for the personal care and cosmetics markets, where safety requirements are extremely high.

Product Specifications:

Active matter content: 70.0 ± 2.0%

Color (5% active matter aqueous solution): ≤ 30 Hazen

pH value (1% active matter aqueous solution): 6.5 ~ 11.0

二、 Company Advantages

1. Technological Leadership & Quality Assurance

With over 30 years of R&D and engineering expertise in sulfonation/sulfation technologies, we have successfully completed more than 200 surfactant production projects across 17 countries worldwide. Our core technologies include:

Continuous Multi-tube Falling Film SO₃ Sulfonation Reactor: Ensures uniform and complete reactions while minimizing dioxane formation. The equipment is designed for a service life exceeding 20 years.

79-Stage Neutralization & Steam Stripping Dioxane Removal Process: When producing 70% SLES, this process reduces dioxane content to below 3 ppm. It boosts production capacity by 35% and lowers unit energy consumption by one-third compared to similar equipment.

Full-Process Green Manufacturing: Incorporates three-stage waste heat recovery, reaction heat recovery, and zero-discharge alkaline wash wastewater technology, achieving low-carbon, eco-friendly production and cost optimization.
