Sodium Lauryl Ether Sulfate (SLES) is a widely used anionic surfactant derived from vegetable oils or petroleum. Due to its high foaming capacity and effective cleaning properties, it is extensively applied in personal care and cleaning products such as shampoos, liquid soaps, and body washes.

Features and Applications:

• High and stable foam generation

• Gentle yet effective cleaning

• Skin and hair friendly

• Used in detergents, cosmetics, and personal care industries

Technical Specifications:

• Chemical Formula: C12-14H25-27O4SNa

• Appearance: Clear to pale yellow liquid

• Solubility: Soluble in water

• 1% Solution pH: 6–8

• Typical Concentration: 28–70%

• Packaging: 200L drums or tanker

Safety and Precautions:

• Avoid contact with eyes

• Store in a cool, dry place

• Seek medical attention in case of ingestion or severe skin contact

Packaging and Storage:

• Durable plastic or metal drums

• Keep away from direct sunlight and high temperatures

Industrial Applications:

• Shampoo and liquid soap production

• Industrial and household cleaners

• Cosmetic and personal care products

• Textile and dyeing industries

In the 1930s, anionic surfactants like SLES were first introduced as alternatives to traditional soaps in industrial detergents, enhancing cleaning efficiency and reducing water hardness effects.

Recent studies indicate that modified SLES formulations can produce more stable foam and improved skin mildness (ResearchGate).
