How to make a benzoyl peroxide wash more foaming/a better cleanser?
The general formula of a benzoyl peroxide wash base is:
Surfactant(s): Cocamidopropyl Betaine or Sodium C14-16 Olefin Sulfonate and in some cases Sodium Lauryl Sulfate
Humectant: Glycerin
Thickener: Carbomer (type A or C)
Preservative: Varies
pH buffer: Sodium Hydroxide and/or Citric Acid and/or Lactic/Glycolic AcidThe general complaint about these formulas are that they are too lotion like/non foaming and non cleansing, how would you make the following formula more foaming/a better cleanser without making it even more drying?
10% Benzoyl Peroxide
10% Cocamidopropyl Betaine
5% Glycerin
1% Carbomer (type?)
1% Preservative
x% Citric Acid to optimize pH/buffer BPNaturally it would have to go through stability testing both accelerated and RT so keep in mind the formula needs to stable enough to ideally see less than 10% BP degradation under the label value over 1 year (or more). -
