Hello, I am a student studying health and beauty products. I want to develop natural sunscreen products from สารสกัดว่านหางจระเข้ mixed with tomatoes, want to know the recipe must What do you use?
Learn the basics of formulation here topic10408.html If focusing on nature, I recommend using it. สารกันแดด Physical ( physical sunscreen ) Maybe try adjusting from the basic sunscreen formula on the page. สารกันแดด and add the ingredients. Aloe Vera Extract (now there is no substance on the website. Tomato extract for sale.)
