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.

No, we are a speciality base supplier, we manufacture and ship soap bases and other product bases that are converted by our customers into finished products. Typically our bases make up around 80-99% of a finished product.

No, we are strictly against animal testing and our ingredients are not tested on animals.

GMP applies to companies manufacturing finished products. As a supplier of ingredients and bases, this does not apply. Stephenson holds ISO 9001 Quality Certification and supplies companies that have GMP certification.

We've been making soap here at Stephenson’s since 1856, originally for the textile industry.

Yes, all the glycerine used in our soap bases is derived from vegetable sources.

Most of our product are vegan friendly. Only small amount of our products contain animal-derived milk and honey. These include Crystal Goat’s Milk, Crystal Donkey Milk and Crystal Honey.

The pH cannot be adjusted as this will cause the soap to revert to fatty acid at which point solids will form.

The bases are not manufactured for processing at home. Extruded soap bases are used in soap factories, and are converted from noodle form into finished soap bars in one continuous process using pressure, force, and large scale machinery.

Our extruded soap bases are for large scale manufacturing. Extruded bases will not melt in a microwave or in an oven. The moisture/water in these products is very low and they are processed by machines that use pressure and heat caused by friction to bind the soap together and in turn press soap bars.

Conventional Soap making factories and mills that have invested in full scale soap plodding and production machines.

There is no way to process this product / material by hand or under craft conditions.

For our extruded soap bases we supply in two pack sizes, 25KG bags, or 1000KG big bags. Usually we ship in 25KG as this not only protects the soap base but helps to maintain moisture within the product.

78% or higher TFM is usually only possible if soap noodle is made from fatty acid, or oils with the glycerin washed out. As we use full oils with glycerin left in, our TFM is generally 70-75%; see Technical Information attached to the individual products for more information.

We manufacture and produce speciality soap bases; we make our soap base using natural or organic oils, not standard conventional fatty acids. A white soap base is produced by large mills in Indonesia and Malaysia, using fatty acids derived from non-sustainable palm oil plantations (fatty acids are parts of the oils, not the full oil) by using fatty acids the natural colour is removed, the base appears bright white, and the natural glycerine is also removed. We maintain the glycerine throughout the soap making process as it provides excellent skin feel, and a higher quality in the finished product.
