Formula Review for Cream Scrub

Thank you for sharing your cream scrub formula and questions. Based on your goal for soft, non-drying, and whitening skin, and considering the ingredients and previous feedback, here is a review of your formula:

Your formula includes a good blend of moisturizing ingredients like Shea Butter, Glycerin, Grape Seed Oil, Olive Oil, and Fractionated Coconut Oil, which will help achieve soft and non-drying skin. The Soft Cream Maker and Microcrystalline Wax should help create a stable cream base for the scrub.

Regarding your specific questions:

1. Is this cream scrub formula usable?
   The base of your formula with the oils, butters, emulsifier, and wax is generally suitable for a cream scrub. However, as the previous staff reply indicated, the inclusion of Sodium Lactate is not compatible with this formula and should be removed. Additionally, the type of scrub powder and the inclusion of honey (which is not a standard ingredient sold by MySkinRecipes) introduce variables that make it difficult to guarantee the final outcome or stability.

2. Is the preservative (Phenonip) suitable?
   Yes, using Phenonip (Para-Preserve) at 1% is suitable for this type of cream scrub. It is effective against a broad range of microorganisms and is recommended for products that can be easily contaminated, such as jar creams. The usage rate of 1% is within the recommended range for this preservative.

3. Can Sodium Lactate be added at a higher percentage (5%) for exfoliation?
   Based on the previous staff advice, Sodium Lactate is not compatible with this formula and should be removed entirely. Therefore, increasing its percentage is not recommended.

4. Can Lactic Acid be added to adjust pH?
   The previous staff reply stated that the formula will likely have a neutral pH and does not require adjustment. While Lactic Acid (AHA) can be used to lower pH and also provides exfoliating benefits, adding it would alter the pH and potentially the stability of the formula. Given the staff's assessment that pH adjustment is unnecessary, adding Lactic Acid for this purpose is not needed.

Summary of Recommendations:

• Remove Sodium Lactate from the formula as it is not compatible.
• The Phenonip preservative at 1% is suitable.
• Adding Lactic Acid for pH adjustment is not necessary based on the previous assessment.
• Be mindful that the type of scrub powder and the inclusion of honey may affect the final texture and stability, as these are not standard components with defined properties within the system.
