Sodium Lauryl Sulfoacetate (SLSA) (Foaming Surfactant Powder for Bubble Baths and Bath Bombs)
Our Sodium Lauryl Sulfoacetate (SLSA) is a mild, foaming anionic surfactant supplied as a powder. It is made from palm and coconut oils and is used in powdered bubble baths, bath bombs, shampoos, cleansing creams and soaks.
It builds a rich lather and adds viscosity, and it is stable in hard water. Many makers choose it as an alternative to soap or harsher sulphates when they want a gentler foaming ingredient.

How to Make a Simple Bubble Bath Powder
- Weigh. Wear a dust mask. Weigh the SLSA and your other dry ingredients, such as Epsom salts, baking soda and citric acid.
- Mix. Stir the dry ingredients together thoroughly in a clean, dry bowl, breaking up any lumps.
- Add scent and colour. Add a little fragrance or essential oil if you wish. Stir well so it spreads evenly, or pre-mix with a solubiliser such as Polysorbate 80.
- Package. Pour into a dry, airtight jar straight away. SLSA clumps if it picks up moisture.
- Use. Add a few tablespoons under running water in the bath. Test the amount for the foam you like.
Tip: Wear a dust mask when scooping or pouring, and keep the container sealed so the powder stays dry.
Using It in Bath, Hair & Skin Products ▼
These are common maker starting points, not fixed rules. Results vary with your recipe, so always test a small batch first.
| Use | Starting amount | Notes |
|---|---|---|
| Bubble bath powder | Test about 5-15% of the dry mix | Combine with salts, bicarbonate and citric acid. Test the foam. |
| Bath bombs | Test small batches | Mix into the dry ingredients. Too much can make the bomb crumble. |
| Shampoo or body wash | About 2-10% | Add to the water phase with gentle stirring and combine with other surfactants. |
| Cleansing creams and facial cleansers | About 0.5-3% | Use lower rates for gentler products. |
| Shampoo bars | As set by your recipe | Test the lather and bar hardness. |
Tips & Troubleshooting ▼
| Problem | Likely cause | What to try |
|---|---|---|
| Powder clumps | Moisture | Keep it sealed and dry. Break clumps with a spoon, and store with a food-safe desiccant. |
| Dust everywhere | Fine powder | Wear a dust mask and pour gently, ideally over a tray. |
| Bath bomb crumbles | Too much powder | Reduce the SLSA in the next batch. |
| Low foam in hard or oily water | Rate too low | Increase the rate a little or combine with another surfactant. |
| Skin feels dry | Rate too high | Lower the rate and add a moisturising ingredient. |
| Wash separates | Incompatible additives | Do not mix with cationic ingredients such as BTMS-50. Test small amounts. |
