Water-Based, Silicone-Free Physical Sunscreen Ingredient
Question
How can I formulate a physical sunscreen with a light, non-sticky texture (similar to the "ครีมกันแดด SPF35/PA+++ เนื้อเบา ไม่เหนอะหนะ" recipe) that is water-based and silicone-free? What ingredient can be used for the physical UV filter in such a formulation?
Answer
Water-Based, Silicone-Free Physical Sunscreen Ingredient
To create a physical sunscreen that is water-based and silicone-free, you can use Titanium Dioxide Transparent (15nm, Water-Dispersion). This ingredient is a water dispersion of ultra-small particle Titanium Dioxide, making it suitable for use in water-based or oil-in-water sunscreen formulations.
It is designed to disperse well in water and helps prevent whiteness on the skin while providing physical UV protection.
Keep in mind that formulating a stable and effective sunscreen requires careful consideration of all ingredients and their interactions.
