Analysis and Mixing Procedure for a Mild Sulfate-Free Facial Cleanser

Formula Analysis: Mild Facial Cleanser

The formula you provided is a gentle, sulfate-free facial cleanser that focuses on hydration and soothing. Here is the analysis:

1. Cleansing System: The combination of Coco Glucoside and Cocamidopropyl Betaine is very mild and suitable for facial skin. It provides a soft foam without stripping natural oils.
2. Hydration & Soothing: Allantoin, Natural Betaine, Glycerin, and Sodium Lactate work together to keep the skin hydrated and reduce irritation during washing.
3. Texture & Sensory: Xanthan Gum provides the gel structure, while WaterSil™ 8/12 is an excellent addition to reduce the stickiness often caused by high levels of humectants or extracts.
4. Preservation & Stability: Using Mild Preserved Eco™ at 2% is appropriate. However, for a stable and safe product, it is highly recommended to use standardized cosmetic extracts instead of raw natural ingredients (like turmeric powder or homemade coffee water), as raw materials introduce high microbial loads that can cause the product to spoil quickly.

Can it be used daily (morning and evening)?
Yes, this formula is mild enough for twice-daily use.

Recommended Ingredients (Adjusted for Stability)

To ensure the product is stable and safe for use, the following substitutions are recommended:

• Turmeric powder → Replace with Turmeric Extract (standardized for cosmetic use).
• Honey → Replace with Honey Extract (easier to preserve and less sticky).
• Coffee grounds extract water → Replace with Purified Water as the main base to ensure stability.

8. Honey Extract: 5%
9. Fragrance: 0.5%
10. Mild Preserved Eco™: 2%
11. Xanthan Gum: 1%
12. Sodium Lactate (60% Liquid): 3%
13. WaterSil™ 8/12: 1%

Mixing Instructions

1. Prepare the Water Phase: In a main beaker, mix Purified Water, Allantoin, Natural Betaine, and Sodium Lactate. Stir until completely dissolved.
2. Create the Gel: In a separate small container, mix Xanthan Gum with Glycerin to form a smooth slurry (this prevents clumping). Pour this slurry into the water phase while stirring continuously until a uniform gel forms.
3. Add Surfactants: Add Coco Glucoside and Cocamidopropyl Betaine to the gel. Stir very gently to avoid creating excessive foam.
4. Add Actives & Sensory: Add Honey Extract, Turmeric Extract, WaterSil™ 8/12, and Fragrance. Stir until well combined.
5. Preservation: Add Mild Preserved Eco™ and stir for at least 5 minutes to ensure it is fully incorporated.
6. pH Adjustment: Check the pH of the final product. It should be between 5.0–6.0 for facial use. If it is too high, you may need to add a small amount of Citric Acid solution to lower it.
