At Innospec our surfactant range provides endless opportunities for effective surfactancy that are sulfate-free, EO free and 1,4-dioxane free. Our surfactant range also consists of performance concentrates that help the formulator with ease of handling and compact solutions. We are the go-to suppliers in formulating with surfactants.
Under the NANSA® LSS brand is a range of globally approved Alpha Olefin Sulfonate (AOS) based products that are designed to have excellent detergency and foam and good wetting power to suit the Home and Personal Care market. They are also an exceptional replacement for Ethoxylated Sulfates, notably being 1,4-dioxane free.
The key benefits of NANSA® LSS series include:
- Sulfated surfactants, EO, Nitrosamine and 1,4-dioxane free
- Moderate irritant on skin and can be co-formulated to be mild
- Voluminous foam as stable as Sodium Lauryl Ether Sulfate (SLE2S)
- Luxurious and creamy foam as Sodium Lauryl Sulfate (SLS)
- Superior foaming at low T and with high fat and oil load
- Excellent detergency
- Superior wetting ability under adverse conditions
- Stable across a wide range of pH
- Hard water tolerance
- Stable in both acid and alkali
- Viscosity modification with NaCl
- No aquatic toxicity (no H400 phrases)
- Readily biodegradable in aerobic conditions
- Available in liquid and dried forms
NANSA® LSS finds its application in a broad range of Home and Personal Care formulations:
- Laundry Powders Liquids and Sheets
- Manual Dishwash powders and liquids

- Toilet Bowl cleaners – acidic
- Shampoo

Due to the demand for SLES at both low and high liquid concentration, Innospec has designed a new NANSA® LSS grade to the series, NANSA® LSS 70, which is an alternative for those using SLES at 70
With all of the benefits of an AOS chemistry, NANSA® LSS 70 has further benefits to the formulator:
- Pumpable paste at temperature higher than 55°C
- High Active anionic matter: typically 68
- Suitable for the preparation of super concentrated detergent systems
- Compatible over a broad pH range: AOS is a sulphonate and is not prone to hydrolysis (which happens for SLES 70 as it is a Sulphate)
- Compatible with high temperatures: No risk of thermal hydrolysis (which happens for SLES 70)
- Hard water tolerant: AOS Calcium and Magnesium salts are fully water soluble
- No preservative
- Moderate irritant on skin
- Optimized logistics – ship less water and more active
