Please allow me to comment. From what the team used to educate me. - In the case of general soap, such as glycerin soap. will have a high alkalinity and there was a problem with adding active ingredients to the formula because alkalinity would destroy the quality of most of the active ingredients, resulting in quality loss. - In the case of bar soap caused by
Amino acid The resulting pH is in the near neutral range. Or maybe it's a weak acid. which has no problem with any ingredient You can add ingredients to the formula. - If it's a liquid soap, adjust the pH in the range of about 5.5, then you can add the ingredients to the formula. - But in the formula for cleaning the skin. One major issue with the active ingredients in formulations is the expected efficacy of the active ingredients. Since the active ingredients are in contact with the skin for a short period of time, some active ingredients may not be effective. It has been washed away. in skin cleansing formula It washes off the skin in no more than 30 seconds - 1 minute, meaning the active ingredients only work for a very short time. Although not every ingredient is required it takes time to get absorbed into the skin. But there are very few items that can act that quickly. And most of the time this group is usually
AHA ,
BHA , PHA (hydroxy acids group) -
Vitamin C (L-ascorbic acid) (Fine) with
Safe-B3 ™ (
Niacinamide ) should not be in the same formula. because of the group
Vitamin C Either way, it can bind to
Vitamin B3 is formed as a new substance. which causes the original substance to deteriorate And can cause skin irritation in people with sensitive skin -
Salicylic Acid (
BHA ) is insoluble in water. can dissolve in
Isopentyldiol Thank you.
