Herbal Kaffir Lime Shampoo Formulation Advice

Regarding your herbal kaffir lime shampoo formulation and adding Lauryl Glucoside for foam:

1. Recommended concentration for Lauryl Glucoside: For adding foam to your shampoo using Lauryl Glucoside, a usage rate of 5-25% is generally recommended. For a gentle formulation, starting around 5% is advisable.

2. Is Lauryl Glucoside alone sufficient? Lauryl Glucoside is a gentle, naturally derived surfactant, but it does not produce a lot of foam on its own. Using it alone may not provide the desired level of lather for a shampoo. It works best when combined with other surfactants that are good at creating foam.

3. Other ingredients for foam and a natural formulation: To achieve better foam while keeping the formulation as natural as possible with minimal chemicals, it is recommended to blend Lauryl Glucoside with other gentle, naturally derived foaming agents. Suitable options include:

   • Coco Glucoside
   • Decyl Glucoside
   • Coco-Foam-50™ (Cocamidopropyl Hydroxysultaine)
   • IseFoam™ (Sodium Lauroyl Methyl Isethionate)
   • Powderly Foam™ (Potassium Laureth Phosphate)
   • Apple-Foam™ (Sodium Cocoyl Apple Amino Acids)
   • Potassium Cocoate

   By combining 2-3 of these gentle surfactants, you can create a balanced shampoo with good cleaning performance and satisfactory foam. The specific ratio would depend on the desired properties of the final product.

   Additionally, Lauryl Glucoside and many other natural surfactants are alkaline. You will need to adjust the pH of your final shampoo to a skin-friendly range of 5-6.5. You can use natural acids like Citric Acid or Lactic Acid for this purpose.
