Ammonium Lauryl Sulphate (ALS) is a widely used anionic surfactant in personal-care and cosmetic formulations. It is particularly popular in shampoos, body washes, liquid hand washes, shower gels, and other rinse-off products because of its strong cleansing performance and rich foam-producing properties.
For cosmetic manufacturers and beauty brands, selecting the right surfactant is an important part of developing an effective formulation. Ammonium Lauryl Sulphate can serve as a primary cleansing and foaming ingredient in a variety of personal-care products.
What Is Ammonium Lauryl Sulphate?
Ammonium Lauryl Sulphate, commonly abbreviated as ALS, is an anionic surfactant also known as ammonium dodecyl sulfate. It contains an ammonium salt rather than the sodium salt found in Sodium Lauryl Sulphate (SLS).
As a surfactant, ALS helps reduce the surface tension of water and assists in removing dirt, oil, and impurities from hair and skin. It is also valued for producing abundant foam, making it suitable for products where consumers expect a rich lather.
Benefits of Ammonium Lauryl Sulphate in Cosmetic Formulation
1. Excellent Cleansing
ALS provides effective cleansing and can help remove excess oil, dirt, and product buildup from hair and skin. This makes it particularly useful in shampoos and cleansing products.
2. Rich Foam Production
One of the main reasons formulators use Ammonium Lauryl Sulphate is its strong foaming ability. It can produce rich lather in shampoos, body washes, shower gels, and other rinse-off products.
3. Versatile Ingredient
ALS can be incorporated into different personal-care formulations, including:
- Shampoo
- Clarifying shampoo
- Body wash
- Shower gel
- Liquid hand wash
- Bubble bath
- Liquid soap
- Pet shampoo
4. Suitable for Surfactant Blends
ALS can be combined with other surfactants to create a balanced cleansing system. For example, formulators may combine it with Cocamidopropyl Betaine (CAPB) and other secondary surfactants depending on the desired foam, viscosity, cleansing performance, and skin feel.
Ammonium Lauryl Sulphate in Shampoo Formulation
Shampoo is one of the most common applications of ALS. A typical shampoo formulation may include a primary surfactant, secondary surfactants, conditioning ingredients, viscosity modifiers, preservatives, fragrance, and pH adjusters.
According to Stexol Chemicals’ product guidance, ALS may be used at approximately 10–15% in shampoo formulations, with the final level adjusted according to the complete formulation and desired performance.
The final formulation should always be tested for properties such as:
- Foam quality
- Viscosity
- pH
- Clarity
- Stability
- Skin and hair feel
ALS vs. SLS: What Is the Difference?
Both Ammonium Lauryl Sulphate (ALS) and Sodium Lauryl Sulphate (SLS) are anionic surfactants used for cleansing and foaming.
The primary difference is the counter-ion: ALS contains an ammonium group, while SLS contains a sodium group.
The choice between different surfactants depends on the product type, formulation objectives, desired sensory properties, compatibility with other ingredients, and target consumer requirements.
Why Choose Quality ALS for Cosmetic Manufacturing?
Raw-material quality is important when developing consistent cosmetic products. Manufacturers should consider factors such as:
- Consistent product quality
- Appropriate specifications
- Certificate of Analysis (COA)
- Reliable supply
- Suitable packaging
- Formulation compatibility
- Technical support
Stexol Chemicals supplies cosmetic raw materials with COA support and offers quantities suitable for product testing as well as larger-scale production. Its website also highlights formulation guidance through its ChemAssist service.
