Glycerine soap is a popular type of soap that contains glycerin, a natural by-product of soap making that helps keep skin moisturized. However, there are different variations of glycerine soap available in the market today that offer additional benefits to the skin. Some synonyms for glycerine soap include vegetable glycerin soap, transparent soap, clear soap, and melt and pour soap. Vegetable glycerin soap is made with natural ingredients such as coconut oil and shea butter and is suitable for vegans. Transparent soap, on the other hand, is made using a different method that allows it to be translucent and is often scented with essential oils. Melt and pour soap, as the name suggests, is a pre-made soap base that can be melted and customized with fragrances or colors.
