Gentle Herbal Shampoo Formulation with BabyFoam™

Yes, you can use BabyFoam™ as the sole surfactant in your gentle herbal shampoo formula. BabyFoam™ (Sodium Cocoyl Isethionate) is a gentle anionic surfactant that can be used as the main cleansing agent.

You mentioned that using 6% felt not clean enough. The recommended usage rate for BabyFoam™ is quite broad, ranging from 5% to 60%. To achieve better cleaning power, you can certainly increase the concentration of BabyFoam™ beyond 6% within this recommended range. The optimal percentage will depend on the specific herbal powders used (as some powders can affect cleansing performance) and the desired level of cleanliness, but you can experiment with higher percentages like 10-20% or more until you achieve the desired result.

Additionally, the description for BabyFoam™ recommends adding Disodium EDTA at 0.1% to help prevent the BabyFoam™ from hardening or settling over time, which is particularly helpful in liquid formulations.

While BabyFoam™ can be used alone, for enhanced foam and foam stability, especially when incorporating herbal powders, you might consider combining it with other gentle co-surfactants such as Mild-Wash™ (Sodium Cocoamphoacetate or Sodium Lauroamphoacetate) or Coco-Foam™ (Cocamidopropyl Hydroxysultaine). These can help improve the overall performance and feel of the shampoo.
