Cleansing Water Formulation Questions

Based on your questions and the reply from cosmeceutical7 (C7):

1. Using only PEG-7 Glyceryl Cocoate (cocowash) vs. PEG-6 Caprylic/Capric Glycerides (Makeup wash):

   • Yes, you can make cleansing water using only PEG-7 Glyceryl Cocoate. C7 confirms that both ingredients function similarly as cleansing agents.
   • The main difference is viscosity: PEG-6 Caprylic/Capric Glycerides is more liquid, which can make wiping easier. PEG-7 Glyceryl Cocoate is thicker but much more cost-effective. If budget is a priority, using only PEG-7 Glyceryl Cocoate is sufficient.

2. Is the provided formula for a rinse-off product?

   • Yes, the formula appears to be intended for a rinse-off cleansing water, as indicated by C7's discussion in the context of "wiping and rinsing off."

3. Propylene Glycol vs. Monopropylene Glycol:

   • Yes, Propylene Glycol and Monopropylene Glycol are generally the same substance (Propane-1,2-diol) and function similarly in formulations.

Additional advice from C7 regarding your formula:

• For a rinse-off product, C7 suggests omitting Rhamnose as it is expensive and its benefits are better utilized in leave-on formulations.
• Salicylic Acid at 0.1% may be too low for effectiveness in a rinse-off product and might not dissolve well. C7 recommends using at least 0.5% and suggests considering Salicylic Acid EZ™ as a more easily soluble alternative.
