Thank you belassi for guides, will try it asap and let you know how will turn out. Bob, yes will try to use NaOH (10% solution) to thick carbomer. So best thing just to add to carbomer to achive ph of 5 - 5.5 right ? And than add oils in to it?

What i found interesting is, i did as told and i must say i was really happy. But as soon as i add last ingredient-Hydroxypropyltrimonium Honey at 1% it brakes down thicknes. Probably react with carbomer. Can i avoid this somehow (not replacing carbomer/hoey quad)?

You have an anionic cocktail and then you add something cationic, it is BOUND to happen.

@milliachemist is right, you can’t use cationics in your formula at all. Either the honeyquat has got to go, or you have to change your formula drastically.

Hmm, honeyquad is nice for skin, but can be replaced with any other natural ingredient or will not make diference if i pull it out (for skin) ? Also will it make formula unstable or just less thicker ? if i leave it in formula ?
