I have questions about a silicone-based physical sunscreen formulation based on staff recommendations. After understanding the mixing principles, I have the following questions: 1. When using physical sunscreen powders (200nm TiO2 and ZnO), I find that it makes the skin feel very dry. How can I fix this dryness and prevent the skin from looking 'crepey' due to the powder sunscreens used in the following formula: * Titanium Dioxide 200nm: 6% * Zinc Oxide 200nm: 5% * Silicone Blender (ประสานซิลิโคนหลากชนิด): 3% * Silicone Film: 20% * Silicone Gel (Ultra Clear): 37% * Cyclomethicone: 9% * Dimethicone: 20% 2. Is the amount of powder sunscreen in the formula above too high? The product texture is not as smooth as formulas using liquid sunscreens. 3. What would be the approximate SPF and PA values for Titanium Dioxide 200nm at 6% and Zinc Oxide 200nm at 5%? 4. At a usage rate of 20% Silicone Film, it still rubs off the skin. Compared to Vinyl Film at 10%, which adheres better but has an uneven texture (thick in some areas, thin in others), what do you recommend? 5. If I mix various types of long-lasting film formers together, such as Silicone Film, Oil Film, and Vinyl Film, will there be any problems? 6. Based on the recommendation that Silicone Film should be used if the base is silicone, I would like to know if Oil Film or Vinyl Film can be used in a silicone base. 7. When adding the long-lasting film former, I found that the sunscreen sticks strongly to the glassware used for mixing and is difficult to wash off. Are there any techniques for cleaning it? Thank you.

Based on the product description for Retinal (Retinaldehyde), which states it is a yellow-orange powder that degrades quickly when exposed to UV light: Why did the product I received arrive as a **dark brown** color (like tamarind paste) and **very sticky, not a powder**? Has it degraded, or can it still be used?

I am trying to make an oil-based perfume (without alcohol) using natural Essential Oil and chemical Fragrance, with Fractionated Coconut Oil as the carrier oil. I have two questions: 1. Do I need Dipropylene glycol to help dissolve the chemical and natural fragrances together? 2. If I want the scent to last longer, can I use Sugar Fix™ with oil-based perfume? Or is there another more suitable alternative? Note: The product will be a roll-on, not a spray.
