Hello
1.Usually the
วัดค่า pH of any formulation in terms of certain components such as groups
ผลัดเซลล์ผิว that the PH value is suitable It should be in the acidic range. Use case
กระดาษลิตมัส , is it enough for DIY use or not?

ผลัดเซลล์ผิว is categorized as a pH dependent type that must be acidic. to work is group
AHA but if it is The pH independent group does not need an acidic formula. can work because the mechanism of action is different from
AHA Using
กระดาษลิตมัส is enough for measurable. Because it will allow us to know what the pH is around. not required

BHA is one of the brands I currently use. On the label, the PH value of the product is 3.2-3.8, but when I read the ingredients, I found various substances. that require a PH range of around 4-6, for example
Dipotassium Glycyrrhizate ,
Quercetin ,
beta glucan ,
Pantothenate ,
Epigallocatechin Gallate ,
Grape Seed Extract etc. The question is!! Adding any component with PH 4-6 to
BHA Toner with PH approx 3-4 will have a negative effect on any active substance and is I would like to disturb the team to explain the PH value and the active substance to be a guideline for DIY.
BHA tight toner
Most of the active ingredients will work well in the pH range of 3.5-6.5, slightly below this. or slightly higher There are usually no problems with the stability of the active substance or even if there is a problem. but at a very slow level This is an acceptable level. The pH level to be careful of is usually below 3 or above 7.5, where most ingredients will have problems, deterioration quickly and clearly.
The formula has the following problems: yes These list ingredients are electrolyte in nature and will make brazing more difficult. especially when using
Satin Cream Maker is only 0.5% even though it is used

Isopentyldiol where 5% is sufficient per solubility.
Oleanolic acid, however, this part is a separate mixture. which members Must be mixed to dissolve together. before adding it to the formula. which will be added in the last step When the formula is creamy Therefore, note that dissolved together Can be dissolved together well or not. If the solubility is not good to increase the proportion of
Isopentyldiol to be more soluble. Good. However, the team would like to learn to suggest the reverse method, which is to gradually add Olenolic Acid to
Isopentyldiol use only at the rate
Oleanolic Acid is fully soluble in
Isopentyldiol 5%
