Adding Lactic Acid to Oil Soap Shower Gel: Clarity and Formulation

Hello,

Thank you for the review and the Oil Soap formula you formulated and liked. I'm glad you found a product you like!

Regarding your questions about further modifying the formula to add fragrance and 10% Lactic Acid, the team would like to provide the following information:

1. Adding Fragrance (Orange Flavor/Fragrance 1%): This can be done. Adding 1% as proposed in your formula is appropriate.

2. Adding 10% Lactic Acid: According to the team's advice in the previous message, Lactic Acid can be added by replacing the water component in the formula. However, the team mentioned a limitation: if you want the formula to be clear, the amount of Lactic Acid that can be added may not exceed 5%, and the water component must be removed entirely from the formula.

   Therefore, the formula you proposed, which contains 10% Lactic Acid and 3% Water (total 13%), may cause the product to become cloudy. If clarity is desired, the amount of Lactic Acid should be reduced according to the team's recommendation.

3. Checking the New Formula and Mixing Steps:

   • Proposed New Formula:

     1. Oil Soap™ 46%
     2. Fractionated Coconut Oil 39%
     3. Lactic Acid 10%
     4. Vitamin E Acetate 1%
     5. Orange Flavor/Fragrance 1%
     6. Water 3%
        Total: 100%

     This formula has a correct total percentage of 100%. However, the issue is the amount of Lactic Acid at 10% together with Water at 3%. According to the team's recommendation, if clarity is desired, Water should be removed and Lactic Acid should be limited to approximately 5%.

     Example Formula Adjusted According to Team's Recommendation (Emphasizing Clarity):

     • Oil Soap™: 46%
     • Fractionated Coconut Oil: Adjust to 47% (to compensate for the removed Water and reduced Lactic Acid)
     • Lactic Acid: Adjust to 5% (according to the maximum recommended for clarity)
     • Vitamin E Acetate: 1%
     • Orange Flavor/Fragrance: 1%
     • Water: 0%
       Total: 100%

     This formula is just an example of adjusting according to the recommendation for the maximum amount of Lactic Acid for clarity. You can experiment with adjusting the amount of Lactic Acid between 0-5% by reducing Fractionated Coconut Oil proportionally as Lactic Acid is added (and with no Water) to find the appropriate ratio that meets your needs and maintains clarity.

   • Proposed Mixing Steps:

     1. Mix 2 (Fractionated Coconut Oil) + 4 (Vitamin E Acetate) + 5 (Orange Flavor/Fragrance) together.
     2. Pour into 1 (Oil Soap).
     3. Then add Water (6).
     4. Finally, add 10% Lactic Acid (3) directly.

     The overall mixing steps seem reasonable for combining the various ingredients. However, since the team's recommendation is to replace Water with Lactic Acid or remove Water entirely, the step of adding water (step 3) may need to be adjusted to adding the Lactic Acid component instead, or adding Lactic Acid at this step (if there is no water anymore). Adding Lactic Acid towards the end to adjust pH is also a feasible method.

Summary and Additional Recommendations:

• Adding 1% fragrance is possible.
• Adding 10% Lactic Acid may cause the product to become cloudy. If clarity is desired, the amount of Lactic Acid should be reduced to approximately 5% or less, and the water component should be removed entirely from the formula.
• It is recommended to experiment with adjusting the formula starting with a small amount of Lactic Acid (e.g., 3-5%) by replacing the water component, and observe the clarity of the product. Adjust Lactic Acid and Fractionated Coconut Oil up or down to achieve a total proportion of 100% and the desired product texture.
• The proposed mixing steps can be used as a guideline, adjusting the addition of Lactic Acid to align with the formula adjustments regarding water and Lactic Acid amounts.

Hope this information is helpful. If you have further questions or would like help checking the adjusted formula, feel free to ask!
