ingredient compatibility and pH
Hi, Im new to formulating cosmetics & recently got new samples to use in deodorizing/cleaning formulations but Im having trouble understanding the suitable pH:
sodium lauroyl lactylate
Ive searched in ulprospector TDS and some articles to try to understand more but Im not finding enough info…
1) SLL is anionic, yet Ive seen some products that have citric acid or lactic acid in them? 10% solution in water is acidic, wouldnt it be more compatible in basic pH bc of the (-) ? also, HLB is aprox 14, so why is it not very soluble in water?
2) I understand Zn2+ is antimicrobial and works better in acidic formulas, but why is it considered a neutral salt? could it still be antimicrobial in basic solution?
PS: I still dont have a formula yet, bc I dont understand how to use them , but I would like to use them (separately) in very acidic or very basic pH in same or 2 different formulas
