Mixing AminoWash and BabyFoam for Shampoo Formulation and Neutralization
Question
How to mix `AminoWash` (Sodium Lauroyl Glutamate) and `BabyFoam` (Sodium Cocoyl Isethionate) for shampoo formulation? Is neutralization required and how should it be done?
Answer
Formulating Shampoo with AminoWash and BabyFoam
Both AminoWash™ (Sodium Lauroyl Glutamate) and BabyFoam™ (Sodium Cocoyl Isethionate) are gentle anionic surfactants suitable for use in shampoo formulations, particularly for mild or baby shampoos.
Mixing Method:
Both ingredients are in powder form. To incorporate them into a shampoo formula, they should be dissolved in the water phase of your formulation.
Neutralization:
Based on the typical pH range of these ingredients (AminoWash™ is around 5-6, BabyFoam™ is 5.0-5.5 at 10% concentration), neutralization specifically for pH adjustment is generally not required. Their inherent pH is already within a suitable, slightly acidic range for skin and hair products (typically around pH 5.5).
Formulation Considerations:
- Thickening: Since both are powders, you will need to use suitable thickeners to achieve the desired shampoo consistency. Examples of thickeners that can be used include SugarThick™, ClearClean™, Xanthan Gum, EasyThick™, Mild-Wash™, Coco-Foam™, or Flora Foam™.
- Disodium EDTA: It is recommended to include 0.1% Disodium EDTA in the formula to help prevent the powders from hardening or precipitating over time.
In summary, you can mix AminoWash™ and BabyFoam™ by dissolving them in water. Neutralization for pH adjustment is typically not needed, but you will need to add thickeners and potentially Disodium EDTA for stability.
