Cosmetics Formulation Development

Hello, if you want to make sunscreen Total weight 50 g using EHT 5% as recommended amount and use LipidSoft in dissolution, may I ask if this 5% means solution EHT ? EHT 5% = 2.5 g (contains powder EHT 0.11 g + LipidSoft 2.39 g) is it?

Please allow me to comment. - According to the solubility information shown on the web page, solubility Ethylhexyl Triazone in LipidSoft will dissolve Ethylhexyl Triazone up to 4.4% in LipidSoft100% means in 50g will use LipidSoft and uses Ethylhexyl Triazone at 2.2 grams - if my understanding is correct. Suppose if in the formula 100% use LipidSoft 10% will be able to use Ethylhexyl Triazone in the formula is 0.44%, meaning in 50 grams will use LipidSoft 5g and used Ethylhexyl Triazone at 0.22 grams, thank you.

Thank you very much Modtanoy21. Anyway, please disturb the staff to help confirm another voice that If you want to use at the recommended dosage of 5% means... A. Powder EHT 5% of Formula B. Solution EHT 5% of the formula It can be adapted to ส่วนผสมกันแดด .

Hello, the usage rate is the usage rate of the pure substance only. It's not about any other element in the formula. Or the ingredients that have to act to dissolve such substances. Therefore, the usage rate EHT Do not exceed 5% means Ethylhexyl Triazone 5% pure in the formula.

Ask permission from the thread owner to ask questions in this thread as well. - Some substances have a limited solubility in the solvent that has been set. So I was wondering if you mix it in the formula, how will you calculate the % of the required substance? For example Ethylhexyl Triazone from the solubility solubility web page. Ethylhexyl Triazone in สารกันแดด and LipidSoft because Ethylhexyl Triazone powder The formulation must be mixed with a solvent. Up to 14% soluble in OMC ( Ethylhexyl Triazone 14% in OMC 100%) soluble up to 13% in PPG-3 Myristyl Ether ( Ethylhexyl Triazone 13% in PPG-3 Myristyl Ether 100%) Max soluble 6.2 % in Fractionated Coconut Oil ( Ethylhexyl Triazone 6.2% in Fractionated Coconut Oil 100%) Up to 4.4% solubility in LipidSoft ( Ethylhexyl Triazone 4.4% in LipidSoft100%) Think of this as an experiment in the lab to see the solubility efficiency in various destroyers. But if mixing the real formula, there must be other substances in the formula as well. - So I want to ask if there is a way to figure it out. that must be able to use Ethylhexyl Triazone how many % will it dissolve completely? In the specified สารกันเสีย . สารกันเสีย to make 100% total 2. LipidSoft 20% 3. Ethylhexyl Triazone ? % will be able to use Ethylhexyl Triazone how many % max? or you can use any amount that doesn't exceed 5%, thank you.
