Combining Ingredients in a Water-Based Solution

Based on your question and the previous reply, it is not recommended to mix these ingredients into saline solution. Saline solution (sodium chloride) may not be compatible with all cosmetic ingredients and could affect the stability or effectiveness of the final mixture.

As suggested in the previous reply, using distilled water or boiled water is a more suitable base for your formulation. If using boiled water, adding Disodium EDTA at a rate of 0.1-0.2% (recommended 0.2%) can help chelate metal ions in the water, improving the stability of the mixture.

The ingredients you mentioned are generally water-soluble and can be combined in a water-based solution:

• Witch Hazel (Alcohol Free): Known for its astringent properties, helping to tighten pores. The version with Allantoin also provides soothing and moisturizing benefits.
• Allantoin: Helps to reduce irritation and moisturize the skin.
• Safe-B3™ (Vitamin B3, Niacinamide): Beneficial for reducing wrinkles, hyperpigmentation, strengthening the skin barrier, and controlling oiliness.
• Aloe Vera Extract: Provides skin conditioning, reduces irritation (especially from sunburn), and moisturizes.
• ActiveRelease™ Trans-Resveratrol: An antioxidant with potential anti-aging, UV protection, anti-inflammatory, and wound healing properties.

When combining these ingredients, ensure they are fully dissolved in the water base. For ingredients like ActiveRelease™ Trans-Resveratrol, which is a 10% water-soluble powder, follow the recommended usage rate (1-3%) and mixing instructions (add in the last step, avoid heat, use with ActiveProtec™ OX 1%). For Witch Hazel, it should be added in the final step at temperatures below 40°C.

Always perform a small test batch first to check for compatibility and stability before making a larger quantity.
