Review of Your Foam Cleanser Formula

Let's review the facial cleanser formula you've provided for a foam pump bottle.

1. Can this formula be produced?

Yes, this formula appears feasible to produce using the listed ingredients. The percentages of the ingredients are within typical usage ranges for a facial cleansing product. The combination of gentle surfactants, active ingredients, humectants, and a preservative creates a well-rounded formulation. The total percentage of ingredients adds up to 100%, which is correct.

2. Is the pH suitable for a mild facial cleanser?

A mild facial cleanser typically has a slightly acidic pH, close to the skin's natural pH of around 4.5-5.5. Based on the pH ranges of the individual ingredients:

• AminoWash (pH 5-6)
• BabyFoam (pH 5.0-5.5)
• MakeUp-Wash (pH ~6)
• Coco Wash (pH ~6-7)
• Witch Hazel (pH 3-5)
• Encapsulated Salicylic Acid (contains acidic Salicylic Acid)
• Artocarpus Lakoocha Wood Extract (requires formula pH 4-6 for stability)

The presence of acidic ingredients like Witch Hazel and Salicylic Acid, combined with surfactants in the slightly acidic to neutral range, suggests the final formula will likely have a pH suitable for a mild facial cleanser, probably within the 4.5-6.0 range. It is highly recommended to measure the actual pH of your final batch and adjust it if necessary to ensure it is within the optimal range for both skin compatibility and ingredient stability (especially for the Artocarpus Lakoocha Wood Extract).

3. Can Apple Wash be used instead of Amino Wash? What percentage?

Yes, Apple-Foam (Sodium Cocoyl Apple Amino Acids) can be used as a substitute for AminoWash (Sodium Lauroyl Glutamate). Both are gentle anionic surfactants suitable for facial cleansers.

AminoWash is used at 20% in your formula, and its recommended usage rate is 5-25%. Apple-Foam has a recommended usage rate of 5-30%.

Since AminoWash is a powder and Apple-Foam is a liquid with a known active matter (29-34%), a direct percentage substitution might result in slightly different performance characteristics (like foam quality or viscosity) compared to the original formula. However, substituting 20% AminoWash with 20% Apple-Foam is a reasonable starting point as it falls within Apple-Foam's recommended usage range.

You would need to adjust the amount of water slightly to account for the liquid form of Apple-Foam compared to the powder form of AminoWash. It is recommended to make a small test batch and evaluate the foam, feel, and overall performance, adjusting the percentage of Apple-Foam (within its 5-30% range) as needed.
