- Licorice Extract (Glabridin 90%) Oleanolic acid, besides soluble in Butylene Glycol or ethanol and any other solvents? That can dissolve these 2 substances. - And if you put these 2 substances in the recipe, is it necessary to mix oil in the formula as well? - If using Hydroxyethyl Cellulose (HEC) to สารสร้างเนื้อเจล Can I mix these 2 ingredients in the formula? - If using Licorice Extract (Glabridin 90%) 0.05% Oleanolic acid 0.5% It is best to use a solvent that can dissolve these two substances, for example Butylene Glycol How many % will it be able to dissolve these 2 substances? Thank you very much.

Hello Lactic Acid (AHA) Neutralized If added to a formula, the formula has a PH value greater than 4 Lactic Acid (AHA) Neutralized will also be active in ผลัดเซลล์ผิว Is it right? Neutralized type is suitable for ให้ความชุ่มชื้นผิว rather than ผลัดเซลล์ผิว because when neutralized Lactic Acid becomes moisturizer with high efficiency
- Licorice Extract (Glabridin 90%) Oleanolic acid unless dissolved in Butylene Glycol or ethanol and any other solvents? that can dissolve these 2 substances
Sorry, I only have this information. (doesn't mean Other solvents are insoluble. but members must test Because the team has only this information from the manufacturer)
- And if you put these 2 substances in the formula, is there a need for oil to be mixed in the formula as well?
Not necessary
- if using Hydroxyethyl Cellulose (HEC) as สารสร้างเนื้อเจล can be mixed Can I use these 2 substances in the formula?
Yes
- if using Licorice Extract (Glabridin 90%) 0.05% Oleanolic acid 0.5%, use a solvent that can dissolve these two substances, for example Butylene Glycol about how many? % Yes, to be able to dissolve these two substances
. It is estimated that about 5% should be sufficient. In complete solubility (dissolve until clear)

Inquire about Lactobionic Acid Add. If mixed in the formula, the formula has a ph value of more than 4, will it still work in cell renewal? Thank you very much.

Hello, group ingredients ผลัดเซลล์ผิว in these acidic forms Should be left on the skin to be able to work first and then use other products accordingly. The reason is because if using other products follow it. There are two possibilities for this problem: continued use may increase the pH of the skin, rather than being acidic. which is the condition necessary for the group ingredients ผลัดเซลล์ผิว to be able to work well or group acidity ผลัดเซลล์ผิว This results in the product being applied to lose quality.

I recommend starting at 3 percent if there are other oils included in the recipe. But if there are no other oils included in the formula, we recommend 5%.

The higher the pH the higher the efficiency. ผลัดเซลล์ผิว lower. If possible, it is recommended to control around 3.5, but 4.0 can still work.
