Modifying Sulfate Free Shampoo Base for Anti-Frizz Shampoo and Acne Liquid Soap

Dear Member,

Regarding your questions about modifying the Sulfate Free Shampoo Base, the team would like to provide recommendations based on the information you provided and the advice from the admin:

1. Shampoo for Reducing Frizz

You wish to add natural oil and other ingredients to reduce frizz.

• Using Natural Oils: The admin advised that adding large amounts of natural oil directly to shampoo is not recommended because the oil is easily washed off during shampooing and may cause compatibility issues if added in high amounts. Furthermore, oil does not effectively weigh down the hair as well as other ingredients.
• Hair Conditioner: The admin recommended using hair conditioning agents instead of oil to help reduce frizz. You can choose from several types, such as:
  • Silicone Hi-Cond (Aminopropyl Dimethicone) (ID 997): If you are comfortable using Silicone, this provides high conditioning performance.
  • Poly-Conditioner Pro / Eco (ID 1056): If you wish to avoid Silicone, these provide conditioning performance (Pro is higher than Eco).
  • Silicone Quick-Cond (PEG-12 Dimethicone) (ID 1019): Provides moderate conditioning and is easy to use.
• Other Ingredients You Selected:
  • Panthenol (Pro Vitamin B5) (ID 111): Can be added, but the admin recommended not using more than 1% as it is washed off and does not provide much additional benefit above this amount.
  • CTAC (Cetrimonium Chloride) (ID 161): Can be added; it is also a conditioning agent.
  • Essential Oil: The admin recommended not using more than 1% in shampoo formulas, as high amounts can irritate the scalp.
  • Preservative: Essential to add to prevent microbial growth. The admin did not specify a type or exact amount, but 1% as you proposed is a common amount for many preservatives. You should check the recommended usage rate for the specific preservative you choose.
  • Salt: The admin recommended using specific thickeners like EasyThick (ID 1042) or SugarThick (ID 510) at 2-3% instead of salt, as they are easier to use and provide more stable thickening.
• Oil Emulsifier: If you use hair conditioning agents as recommended by the admin instead of adding large amounts of oil, an oil emulsifier is not necessary.

Suggested Shampoo Formula Structure (Revised based on Admin Advice):

• Sulfate Free Shampoo Base (ID 1107): 35%
• Hair Conditioning Agent (choose one from ID 997, 1056, 1019): According to the recommended usage rate for each ingredient (typically 1-5%)
• Panthenol (ID 111): Not exceeding 1%
• CTAC (ID 161): According to the recommended usage rate (typically 0.5-2%)
• Essential Oil: Not exceeding 1%
• Preservative: According to the recommended usage rate for the chosen ingredient (e.g., 1%)
• Thickener (EasyThick ID 1042 or SugarThick ID 510): 2-3%
• Distilled Water (ID 838): Remaining percentage (adjust based on the amounts of other ingredients added)

2. Liquid Soap for Treating Back Acne

You wish to use the Sulfate Free Shampoo Base to make a liquid soap with Salicylic Acid.

• Salicylic Acid: The admin stated that regular Salicylic Acid (ID 148) will not dissolve in this formula. You must use Salicylic Acid EZ (ID 766), which is water-soluble, instead.
• Thickening: The admin recommended thickening the formula using EasyThick (ID 1042) or SugarThick (ID 510) at 2-3% to help prevent Salicylic Acid EZ from settling.
• Skin Nourishing Oil (10%) and Essential Oil (2%): You proposed adding these ingredients. The admin did not provide specific comments on these amounts for the liquid soap formula, but generally, adding 10% oil to a cleansing formula may cause cloudiness or require an emulsifier, and 2% essential oil is quite high and may cause irritation (referencing the caution about scalp irritation in the shampoo section). The admin did not recommend using an oil emulsifier for this formula.
• Preservative: Essential to add to prevent microbial growth. The admin did not specify a type or exact amount, but 1% as you proposed is a common amount. You should check the recommended usage rate for the specific preservative you choose.

Suggested Liquid Soap Formula Structure (Revised based on Admin Advice):

• Sulfate Free Shampoo Base (ID 1107): 35%
• Salicylic Acid EZ (ID 766): According to the desired amount (typically 0.5-2% for acne treatment)
• Preservative: According to the recommended usage rate for the chosen ingredient (e.g., 1%)
• Thickener (EasyThick ID 1042 or SugarThick ID 510): 2-3%
• Distilled Water (ID 838): Remaining percentage (adjust based on the amounts of other ingredients added)
• Note: If you wish to add skin nourishing oil or essential oil, you should test the formula's compatibility and be cautious about potential irritation, especially with essential oil at high concentrations.

We hope this information is helpful for modifying your formulas. If you have further questions, please feel free to ask.
