The following formulation is for a stick mask or a solid mask. This is a water based mask made with marshmallow extract and peppermint. The former is soothing and the latter is cooling. It is a clay mask and as such kaolin clay has been used with the addition of chromium green to add colour. I based this on a few popular stick masks on the market and emulated their general characteristics, adding my own twist. Due to its self preserving nature there is no additional preservation added. Formulation advises on acceptable changes in certain ingredients i.e. extracts.
