Crystals and this weird white thing in a solution product.
This is a solution from 7 month ago. It was crystal clear then with no problem.FormulaTetra sodium EDTA 0.3%Allantoin 0.4%Salicylic acid 0.1%Xanthan gum 0.04%Phenoxyethanol 0.6%Caprylhydroxamic acid 0.15%Glycerin 0.75%WhatpH 5.1Packaging was in 120ml bottles with flip top cap.The weather is cold now and at night up to -10°c so i checked some samples and saw they have some crystals in them as of pictureThen i mixed and heated the contents of 60 bottles to 40°c but the crystala didn’t dissolve.There was also this white weird thing in two bottles as of photos. It remains on top of water and didn’t mix.
My questions are1. What are these crystals?
2. Why they didn’t dissolve again when heated to 40°c and mixed?
3. What is this weird white thing that has formed in two bottles? Yeast or mold or something else?
