1. What It Is

• Foaming Mild Surfactant.

• Appearance: Fine, off-white powder. Highly water-dispersible.

• pH in 1% solution: ~6–8 (skin-friendly range).

2. Functional Properties

• Mild surfactant: Provides rich, creamy foam with a soft skin feel—much gentler than SLS (sodium lauryl sulfate).

• Cleansing: Excellent at lifting oils and soils without stripping the skin or hair.

• Foaming booster: Enhances foam volume and stability when combined with other surfactants (e.g., cocamidopropyl betaine).

• Dispersing agent: Helps suspend insoluble additives (clays, pigments) uniformly.

3. Typical Usage Levels

4. Formulation Best Practices

1. Hydration

   • Pre-slurry SLSA in a small amount of glycerin or propanediol to avoid dust and ensure uniform hydration.

2. Order of addition

   • Disperse into warm water (< 60 °C) under gentle stirring.

   • Add co-surfactants (e.g., amphoteric or nonionics) after SLSA is fully hydrated.

3. pH adjustment

   • Final pH should fall between 5.5–7.0. If needed, adjust with citric acid or sodium hydroxide.

4. Temperature sensitivity

   • Dissolves best at 40–60 °C; avoid overheating (> 70 °C) to prevent mild decomposition.

5. Compatibility

• Good with:

  • Amphoteric surfactants (e.g., cocamidopropyl betaine) for foam stabilization.

  • Nonionic surfactants (e.g., decyl glucoside) to soften foam.

  • Hydrotropes (e.g., sodium citrate) to enhance clarity.

• Caution with:

  • Strong electrolytes (e.g., high salt levels) can reduce foaming.

  • Very high levels of anionic surfactants (e.g., SLS) may reduce mildness benefits.

6. Example Applications

• Shampoo: 10 % SLSA, 2 % cocamidopropyl betaine, 1 % panthenol, 0.5 % fragrance.

• Bath bomb: 30 % SLSA blended with 20 % baking soda, 20 % citric acid, 10 % cornstarch, plus color and fragrance.

• Solid bar: 40 % SLSA + 30 % stearic acid + 15 % cetyl alcohol + 5 % shea butter + 5 % water/glycerin slurry + 5 % additives.
