Ammonium Lauryl Sulfate (ALS) - CAS 2235-54-3

Ammonium Lauryl Sulfate (ALS) CAS 2235-54-3: Composition and Properties

1. Chemical Structure

ALS contains a hydrophobic hydrocarbon "tail" and a hydrophilic sulfate "head"; the ammonium cation provides improved solubility compared to insoluble salts. This makes the substance one of the popular raw materials in the detergent industry.

2. Properties and Parameters

Molecular formula: C₁₂H₂₉NO₄S (approximately)

Appearance: Viscous light-colored mass

Solubility: Good in water, moderate in alcohols

Density: ~1.03 g/cm³ at room temperature

Storage: In tightly sealed containers to avoid loss of quality

3. Applications

Cosmetology: Cleansing shampoos, bath foams, liquid soaps.

Automotive chemicals: Formulations for body washing, special shampoos.

Industrial formulations: Foaming in foam generators.

4. Safety

Skin reactions: Prolonged contact or high doses may cause dehydration of the stratum corneum.

Eye irritation: Requires caution if it comes into contact with eyes.

Environmental aspect: Subject to biodegradation, but the use of anaerobic and aerobic wastewater treatment is recommended.

5. Conclusion

Ammonium Lauryl Sulfate remains one of the main anionic surfactants in the modern cosmetic industry. The balance of foaming, cleansing ability, and acceptable irritation levels allows its use in personal care products and industrial production.
