Just started on my candle making hobby and there are much to learn in order to perfect this art. Came to a point whereby I need help on the above topic, as I am very particular about the chemicals which I mix into my candles. 1) What exactly is an Universal Additive (for candles) ? - I search literally through dozens of pages using google, but there isnt a conclusive answer. 2) Is it safe to mix into a candle and to burn it? - I have spotted no big corporations or wax companies selling such universal additives. Most are selling this product via Etsy, small ecommerce stores or eBay. 3) Can the Universal Additive replace Stearic Acid, UV inhibitor, Vybar all at one go? - From a website, it states that the UA has properties of these 3 separate additives. - Is it really that miraculous? It just that I find the whole "Universal Additive" very murky... Can't really find any information on these. Any recommendations / your thoughts on this matter?
