Formula Review and Suggestions for Facial Cleansing Cream

Based on your formula and the staff's suggestions, here is a review and some points to consider:

1. Will this formula result in a facial cleansing cream?

Your original formula with 30% Amino Wash, Propylene Glycol, and Glycerin would likely result in a liquid or slightly viscous cleanser. To achieve a creamy foam texture like the expensive cleansers you mentioned, incorporating BabyFoam and a thickener like SugarThick, as suggested by the staff, is key.

• Amino Wash is a gentle surfactant that provides a delicate, creamy foam.
• BabyFoam (Sodium Cocoyl Isethionate) is a gentle, high-foaming surfactant that is excellent for creating creamy textures in cleansers, especially when combined with Amino Wash.
• SugarThick (PEG-120 Methyl Glucose Dioleate) is a thickener specifically designed for detergent systems. Adding 2-3% will help increase the viscosity of the formula, giving it a more cream-like consistency before it lathers.

By adjusting the ratio of Amino Wash and adding BabyFoam and SugarThick, you can achieve the desired creamy foam texture.

2. Are there any precautions regarding mixing?

Yes, there are a few points to note when mixing these ingredients:

• Water Phase: Amino Wash, Pure MSM, Propylene Glycol, and Glycerin are all water-soluble and should be mixed in the water phase.
• pH Level: Pure MSM requires the formula pH to be between 3-7. Amino Wash typically has a pH of 5-6, which is suitable. Ensure the final pH of your formula stays within this range after adding all ingredients.
• Thickener: SugarThick is best added at the end of the formulation process with slow stirring. It dissolves more easily when warmed to 50-60°C. You can warm the main water phase or warm the SugarThick separately before adding it.
• Stability: Amino Wash and BabyFoam can sometimes harden or precipitate over time, especially in liquid formulas. It is highly recommended to add Disodium EDTA at approximately 0.1% to help prevent this and improve formula stability.

3. Must a preservative be added?

Yes, absolutely. Since your formula contains a significant amount of water and other ingredients that can support microbial growth, a suitable preservative is essential to prevent bacterial and fungal contamination. This ensures the safety and shelf life of your product. Add a broad-spectrum preservative at the manufacturer's recommended usage rate.

Suggested Formula Adjustments (incorporating staff feedback):

To achieve the creamy foam texture and ensure stability, consider adjusting your formula based on the staff's advice:

• Reduce Amino Wash slightly (e.g., 20-25%)
• Add BabyFoam (e.g., 5-10%) to work with Amino Wash for a creamier foam.
• Keep Pure MSM (5%), Propylene Glycol (20%), and Glycerin (20%).
• Add SugarThick (2-3%) for thickening.
• Add Disodium EDTA (0.1%).
• Add a suitable Preservative (ตามอัตราที่แนะนำ).
• Adjust Water to make up 100%.

This adjusted formula should give you a gentle, effective cleansing cream that washes off without leaving the skin feeling dry, while also having a pleasant texture and good stability.
