Foaming Facial Cleanser Formula: Surfactants, Foam, Glycerin, and pH

Question

Regarding a foaming facial cleanser formula: Is the amount of surfactants (Cond-Foam, BabyFoam™, Cocamidopropyl Betaine) sufficient for cleansing dirt and makeup residue on oily, acne-prone skin? How can the formula achieve a mousse foam texture using BabyFoam™? Is the current amount sufficient, or should Cocamidopropyl Betaine be replaced with AminoWash (Sodium Lauroyl Glutamate) for thicker foam? What is the effect of Glycerin on foam formation and skin feel? Is pH adjustment necessary for this formula, and what is the expected pH range?

Hello,

Regarding your questions about the foaming facial cleanser formula:

Surfactant amount for cleansing: The staff's response indicates that the sufficiency of the surfactant blend for removing dirt and makeup residue on oily, acne-prone skin depends on the individual's level of dirtiness and makeup. It is recommended to test the formula, and if it's not sufficient, you can add more surfactant later.
BabyFoam™ for mousse foam: BabyFoam™ is good for generating foam, but Cocamidopropyl Betaine does not produce much foam. The current amount of BabyFoam™ might be sufficient for a mousse foam, but if you desire a thicker or denser mousse, you could consider increasing the amount of BabyFoam™ or replacing Cocamidopropyl Betaine with AminoWash (Sodium Lauroyl Glutamate), which provides more foam and cleansing, although it is more expensive.
Glycerin's effect on foam: Glycerin itself does not create foam, but it helps the foam develop well. The amount included in your formula is considered appropriate for providing a smooth skin feel and preventing dryness after washing.
pH adjustment: According to the staff, pH adjustment is not necessary for this formula. The ingredients are mildly acidic, and the resulting pH of the formula is expected to be in the range of 5.5-6.5, which is suitable for the skin.

Thank you.
