I am formulating a herbal hand wash with following ingredients
1) Aloe vera extract : 240 ml
2) Decyl Glucoside : 60 ml
3) Guar Gum : 10 gm
4) Glycerine : 7.5 ml
5) Fragrance : 20 drops
My motto is to keep number of ingredients to minimum. I have following questions / problems. Shall be thankful to have answers to the same.
1) The combination is perfectly thick when fresh. But as the time passes, (10 to 12 days) it stats thinning or separating. Shaking helps but that is not the expected solution.
2) pH of my final formula is in the range of 4.5 to 5. I think this is in tune with the pH of human skin. Am I right? & is this approach scientific?
3) I am making general purpose hand wash. Should every soap formulation be antimicrobial as well?
