Ascorbyl Tetraisopalmitate and Phenylethyl Resorcinol can be ignored in Ultra Solve or not and bring it Mix in the water Hada must add สารนำพา which one is wrong?

Hello, but the usage rate Ultra Solve might be quite high (3- 4 times of Ascorbyl Tetraisopalmitate and Phenylethyl Resorcinol ), which means if the rate of use Ascorbyl Tetraisopalmitate and Phenylethyl Resorcinol in the formula is low. no problem but if used at a rate of 3-5% becomes required 15-20% Ultra Solve 15-20% which is not appropriate. yes
