Sodium Cocoyl Apple Amino Acid
I have 3 general questions..<div>
I’ve been told by one supplier that Sodium Cocoyl Apple Amino Acid needs to stay above a pH of 5.5.. but another 2 suppliers claimed that is not the case. Hopefully @MarkBroussard could shed some insight? Going through the forum I see that Mark has talked about this ingredient with some experience. Is there a need to worry about the pH for this ingredient, if so what is the reasoning? Being able to bring it to a pH below 5 would be ideal!
My follow up question would be preservative with a product utilizing this ingredient. If the pH of above 5.5 holds true. What has been proven effective above a pH of 5.5?
Below 4.8 I have seen many effective preservatives and systems recommended in this forum. But what about say a pH of 5-7 or 7-10? I don’t see many within this range recommended for a surfactant based system. I would love to hear some non paraben, non formaldehyde recommendations for this use range. I’ve seen on this forum you can’t always go by the manufacturer/resellers website. They claim said preservative is good from pH 3-6.5 but in truth sub 5 is only effective. So I’d like to see what holds true in 5-7 and 5-10.
Lastly, Sodium Cocoamphoacetate.. amphoterics I’ve read in an acidic pH is considered cationic, in basic pH is anionic.. so does sodium cocoamphoacetate not play well with anionics at a pH below 7 (acidic) where it is then considered cationic? Or is there something special here I am missing that this isn’t a problem?
That may be more than 3 and I apologize but greatly appreciate the knowledge here! Please excuse my inexperience, I’m young, fascinated with learning about ingredients not commonly used, and find experimentation a supplement to my learning. Thank you!
