Cosmetics Formulation Development

I would like to learn about the substances used in the sunscreen formula and the color used in the foundation formula. Because we are interested in developing a formula for sunscreen and foundation in many shades. Focus on gentle substances, do not add แอลกอฮอล์ ซิลิโคน or a substance that does not cause acne and clogs. Now developed a sunscreen formula ordered from the company myskin using the substance Tris-Biphenyl Triazine as สารกันแดด put 10% in the formula but When applied on the skin will be a little difficult to blend Not very slippery What substance can we modify? Then it will develop into a formula for various shades of foundation. Just have a look at the website. Can't decide which color to use? what color Please advise on the color used in the development of foundation formula. thank you very much

Hello, skin adjustment reduce stickiness If you are not comfortable using silicone, use LipidSoft eg LipidSoft Dry II, LipidSoft Lite , starting at 5-7%, for blending, I recommend trying MatteSilica 3% The formula is easier to blend and smoother.

thank you very much
