Melt & Pour FAQs

These are some of our most common questions we receive about our Melt & Pour products. If there is something else you’d like to know, please contact us and a member of the Stephenson team would be more than happy to assist.

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.

No - Melt & Pour is different to 'cold process' and thus does not need to cure. Our Melt & Pour base is already reacted and cured. Once melted you simply pour, and leave to set. The term 'cure' is used to describe saponification, when the product is still reacting and neutralising fatty acid content whilst setting. This is not the case with Melt & Pour.

This depends on the size of your mould or loaf. The larger the surface area the longer it will take to set. A normal loaf will take roughly 6 hours to fully set. This can also change depending on the ambient temperatures you let the base set in.

There is no limit on how many times you can re-melt. Be aware of any moisture you may lose during this process as this can alter the balance of the formulation. Always cover the soap base when you melt it.

If you are slicing Melt & Pour soap base (Any Crystal bases) we would recommend using a large knife or a soap cutter, or a soap mould slicing tool/machine. If you're cutting from an 11.5kg box we recommend cutting top to bottom.

If you are slicing Melt & Pour syndet base (Syndopour 200-MB) we would recommend using cheese wire.

This is quite a common problem described as 'bleeding'. Most Melt & Pour crafters use water-based food colourings, these are water-soluble and Melt and Pour is a water-based product, thus when these colours are inside a soap they often bleed as it runs through to the entire body of the product. There are alternatives to this, such as pigments or non-bleeding colourants available but they might not be as simple to use.

This is a common issue with some of our opaque the white pigment (titanium dioxide) can drop within the soap base as it cools when we run large volumes or in the summer months as it takes longer to set. Don’t panic, simply cut the block of soap base from top to bottom in an even cross-section, then re-melt, mix, and you will see that the white (titanium dioxide) will be even throughout the finished soap bar/product.

This is due to the bars being un-wrapped. Almost all of our Melt & Pour products contain Glycerin (a moisturizing agent) and because Glycerin is a humectant, it pulls moisture in from the air which is great when you apply it to your skin, but not so great when displaying unwrapped bars.

When the bars are left out in higher dry ambient temperatures they will begin to lose some of the water/moisture. This results in a loss in size, weight and shape.

Cut the base down to manageable pieces, chunks or slices. You can then add to a heated vessel, pot, or melt in the microwave - make sure you watch the temperature, as it is possible to lose moisture and water content from the base overheating.

Overheating can also cause the base to boil over so make sure you remove and stir intermittently.

Normally we would recommend silicone moulds, as metal moulds can often stick to the product, but moulds for chocolate often work well too.

The temperature for each Melt & Pour base can differ. You can find the product-specific temperature on the product INCI document, which can be found here.

It's very important to wrap the soap/syndet as soon as you have released it from the mould. The fewer surfaces in contact with the air the better so wrap in a cling film/cello film type product. This is important to prevent sweating and also moisture loss.

We offer 2 types of packaging for our Melt and Pour soap bases - 1kg trays and our ‘patent pending’ 11.5kg / 25lb soap box.
