Formulation Questions Answered

Here are the answers to your formulation questions:

1. Stabilized Vitamin C (Natural-C Glycol™) and Fragrance

Yes, you can add fragrance to Stabilized Vitamin C (Natural-C Glycol™) Serum. However, it is recommended not to exceed 1% fragrance in the formula to maintain stability. Adding other ingredients is generally not recommended as it may affect the stability of the vitamin C, unless you consult with the R&D team first.

2. MatteSilica XL™ vs. MatteSilica™ in Primer and Other Formulas

MatteSilica XL™ can be used in primer formulas and is not limited to just powder formulations. Both MatteSilica™ and MatteSilica XL™ are suitable for mixing into various textures, including gels and creams, to provide a matte finish and absorb oil. MatteSilica XL™ is specifically developed for higher oil absorption compared to the standard MatteSilica™.

3. Solubility of Silicone Film in Silicone Gel

Yes, Silicone Film can dissolve in Silicone Gel. Silicone Film is soluble in silicones, and Silicone Gel contains silicones such as Dimethicone and Cyclomethicone.

4. Best Emulsifier for Waterproof Sunscreen: SiliSolve Plus™ vs. Water-in-Oil EZ™

Both SiliSolve Plus™ and Water-in-Oil EZ™ are water-in-oil emulsifiers suitable for creating waterproof formulations like sunscreen. However, Water-in-Oil EZ™ is specifically highlighted for its water-repellent ability and durability on the skin, making it particularly suitable for sunscreen formulas that require these properties. It is often used in popular sunscreen products.

5. Best Antioxidant Against Sunlight Free Radicals

Several antioxidants can help protect against free radicals caused by sunlight (UV radiation). Among the options discussed:

• ChromaDetox™ (Dimethylmethoxy Chromanol) is a potent antioxidant that provides triple protection against various reactive species, including those caused by UV radiation. Studies show it can improve antioxidative capacity and reduce signs of photoaging.
• Astaxanthin is also described as a powerful antioxidant that helps protect the skin from UV damage.
• ActiveProtec™ UV contains a combination of UV absorbers and Vitamin E to protect ingredients in the formula from UV damage and fight free radicals.

For protecting the skin against free radicals specifically from sunlight, ChromaDetox™ (Dimethylmethoxy Chromanol) and Astaxanthin are strong candidates based on their described properties related to UV protection and fighting oxidative stress in the skin.

6. Water Type for Clay Masks

For formulating clay masks and other cosmetic products, it is best to use distilled water or deionized water instead of regular tap water. Tap water contains minerals and potential microorganisms that can affect the stability, purity, and shelf life of your product.
