Two suggestions here @Snehajoshi : increase the level of coco-betaine relative to SLES by a lot: increase betaine/reduce SLES. Also increase the EDTA since your water in India has more hardness (Ca++, Fe+++) then other places. I would double the EDTA, assuming it is tetrasodium EDTA..

@chemicalmatt hi, i was reading this post and want to ask your opinion. I’m in Indonesia and i believe it has hard water problem.
1. My handwash formulation always use 0.2% disodium edta. Do you think this is enough?
2. I always thought 0.2% will be enough to boost preservative efficacy. Apart from that I have no idea what benefit it bring.
3. Do you prefer tetrasodium edta over disodium edta?
Thank you
