I’m new to making DIY lotion and liquid soaps. I’m just making them for myself at this time. I’m not sure if I’ll end up giving any away as gifts or get into selling products. I just read a recipe for 1% hyaluronic acid using germall. The preservative I have is Optiphen plus. I am wondering if directions change for this preservative. Does the distilled water need to be a certain temperature for adding this preservative? After adding preservative the instructions say to add the hyaluronic acid and let it sit for 10 hours; some say up to 24 hours but my question is just about using a different preservative. Thanks so much
