As you may know already, Fragrance oils are a mixture of natural and synthetic ingredients. With these combinations manufacturers are able to produce amazing scents such as dark chocolate, baby powder and many more.
But there can be an ingredient in there that does a bit more than give your product a lovely smell and actually discolour the soap.
It goes by the name of Vanillin - this is a common ingredient in many fragrances which has the side effect of turning soaps brown over time. You won't notice anything to start with, but in a few days the soap will take on a lovely shade of light brown and can go even darker. It can happen in both cold process and melt and pour soap bases too.
To make it easy for you, our aim is to stock vanillin free fragrances so that you don't come up against this issue. So you will see that our Vanilla Cream and Coconut fragrance oils are non discolouring. Where we are 100% sure of a vanillin free fragrance we do put it in the fragrance description.
However, sometimes when we do have a fragrance that has vanillin in it and we will put it on the website. eg Vanilla, Sandalwood & Patchouli fragrance oil does have a small amount of vanillin in it and so we like to tell you so you can take a view.
Using a fragrance containing vanillin isn't a problem - but if you're not aware of how it can discolour your soaps you may be in for a surprise.
But if you're not sure - just send us an email and we'll get a definite answer for you.
