Propylparaben is a lot like Methylparaben in that its primary use in cosmetics and skin care products is as a preservative to prevent fungal and bacterial growth so that the natural products we like to use on our faces and skin stay just as fresh as the day we purchased them. The main difference between this and Methylparaben is that this particular paraben is a preservative most often found inside of liquids, where as you’d find Methylparaben inside of solids most often. Propylparaben is typically a water based preservative.

As far as toxicity of this chemical is concerned, it – unlike Methylparaben before it – is an irritant to the skin and internal system when used in high concentrations. The concentration found within our Detox Shampoo however is minute, so there is little worry on that front. But be advised to look at your normal skin care products and hair care products for ingredients like this that are often included in the ingredient list, but can cause more harm than good when not used in minimal amounts. The use of the Propylparaben here is not only as a preservative for the product, but also a preservative of your hair.

With the Detox Shampoo being a masking agent, and needing to coat the hairs on your head or body, you need to make sure that since it’s going to be there for some time (usually a 10 hour span) that the product isn’t going to go bad quickly or even at all as they lab will cut the hairs away from your head and body and take a few days to process them. So long as the products use a preservative in them and the product is still active on your hair during the time it was removed from your body then there is little worry that your particular hair sample will have gone bad in the time it took the lab to process and test the sample.
