Product possibilities across sustainable skincare, cosmetic and hair care are endless with Durosoft, our range of naturally derived polyglyceryl esters.
The majority of our bases are gluten-free - if you require further information please contact us here.
We use palm and palm kernel oils, and ingredients derived from both oils. Wherever possible, we use oil and ingredients from certified sustainable sources. All products that are made using certified sustainable palm and palm ingredients have the letters SG or MB at the end of their name referring to RSPO Segregated (SG) and RSPO Mass Balance (MB). It isn’t possible to source everything we use from certified sustainable sources, but we are always researching and discussing with our suppliers to find new options.
Lye (also known as Sodium Hydroxide or Potassium Hydroxide) is the material that is used in making all of our soaps. Solid soaps (Crystal Melt and Pour range or Extruded soap bases) use Lye from Sodium Hydroxide, while Stephenson Liquid soaps use Lye from Potassium Hydroxide. We use Lye to saponify oils and/or fatty acids to produce soap. Once the soap is produced, all the lye is used up during the saponification reaction and so there is none left in the final product.
