Why Most Customers Choose SLES Over LABSA？

Both LABSA and SLES are common detergent raw materials.Why is the market demand and consumption volume of SLES much higher than LABSA?Let’s find out.

1. Detailed Product Comparison (Properties, Specifications, Price and so on)

Item	SLES (Sodium Laureth Sulfate)	LABSA (Linear Alkyl Benzene Sulfonic Acid)
Appearance	White / light yellow viscous paste, transparent when high purity	Dark brown viscous liquid, darker color
Active Content	Main grade: 68% / 70%	Standard: 96%
Price Level	Generally higher	Relatively lower
Key Form	Liquid, easy to thicken with salt	Liquid, must be neutralized to LAS (sodium salt) before use
Mildness	Much milder, low skin & eye irritation	Higher irritation, mainly for heavy duty cleaning
Hard Water Resistance	Excellent	Average, performance drops in hard water
Compatibility	Good compatibility with non ionic and amphoteric surfactants	Incompatible with cationic surfactants
Main Applications	Personal care, liquid detergents, high end industrial cleaning	Laundry powder, heavy duty industrial cleaning, low end cosmetics

2. Why SLES Has Much Higher Demand & Usage Volume

Although SLES and LABSA have similar basic uses, SLES is far more widely demanded for the following key reasons:

(1) Wider Application in High Growth Markets

•Personal care products:As a mild surfactant, SLES is the preferred raw material for shampoos, body washes, hand soaps and facial cleansers. LABSA exhibits strong irritation and is rarely adopted in personal care formulations.

• Liquid cleaning products:SLES delivers stable foam, easy thickening and excellent hard water resistance, making it ideal for liquid laundry detergents and dish soaps. LABSA is not well-suited for liquid formulations.

(2) Better Formula Performance

· Milder and safer, suitable for daily chemicals, baby products, and sensitive skin.

· Better hard water resistance, so it performs well in most regions worldwide.

· Easier to thicken, which is essential for liquid cleaning products.

· Stronger compatibility, supporting more diversified and high end formulations.

(3) Compliance with Global Consumption Trends

Modern consumers prefer mild, high quality, liquid form cleaning and personal care products, which directly drives strong and continuous growth in SLES demand. LABSA is mainly used in low cost powder detergents and heavy duty industrial cleaning, with limited growth space.

(4) Environmental and Regulatory Advantages

SLES has high biodegradability and meets strict environmental requirements in many countries, further supporting its larger global consumption.

LABSA is competitive only in low cost, heavy duty cleaning fields. SLES covers personal care, high end liquid detergents, and industrial cleaning, making it the most widely used and in demand surfactant globally.
