How to Use Melt and Pour Soap Moulds.

With the big advances in soap making technology over recent years, it is now possible to make moulded soap bars in the home, that rival in appearance and beauty, those found in decorative soap gift and bed and bath shops.

But it gets even better, in that you can personalise your soap by using custom soap moulds and your favourite scents and colours. Because you will start your soap making process using ready-made soap bases. All the hard work has been done for you!

You get to do the fun part, choosing from our hundreds of mould shapes, deciding what colour you would like and adding a fragrance that appeals to you. It is even possible to add some natural additives such as lavender, chamomile flowers or oatmeal for that special unique appeal.

It takes only minutes to create these home-made soaps, that you can use for your family or as gifts.

The most popular of the soap bases that are being used, are the transparent Glycerine soap base and the white opaque Coconut base.

The Coconut base is moisturising, has a balanced ph and is vitamin E enhanced and contains only coconut and vegetable oils-no animal products are used.

The Glycerine base is virtually transparent. It is also very moisturising and creates a gentle, pure lather .It also is vitamin E enhanced, ph balanced and contains no animal products.

These bases are available in 500gm and 1kg blocks. They melt easily in a microwave or in a double boiler on the stove.

Soap moulds are available in a wide range of designs and we manufacture them in both the economic plastic form and in the new silicone moulds capable of reproducing extremely fine detail in your finished soaps. Both can be easily cleaned with hot water and reused.

To make your soaps you will need:

Creamy Coconut Soap (white) base

Gentle Glycerin Soap (transparent) base.

Colour chips or liquid soap colourants

Fragrance oils

Soap mould of your choice

Pyrex measuring containers

Wood or metal mixing spoon

Knife for cutting soap

Microwave or double boiler for melting the soap.

How to Make the Melt and Pour Soap (Using Double Boiler)

  1. Cut the soap base into 20-30 mm chunks for quick easy melting.
  2. Use a double boiler or make one by filling a saucepan with about 5 cm of water and place on stove. Place a Pyrex container in the saucepan and add the soap chunks to the container. Cover the Pyrex container with shrink film, to prevent evaporation. Start melting using medium heat.
  3. Stir at regular intervals to make sure all the base is completely melted. Do not overheat the soap base.
  4. Now add colour making sure it is cosmetic grade. If using colour chips you may need to reheat for a few minutes to completely dissolve the colour chips. If using mica powdesr or liquid colour, it will mix in immediately.
  5. Add liquid scent a few drops at a time until you are satisfied it is strong enough. Add a little more than you think you need as fragrance dissipates as soap hardens. Start with 5-10ml per 500 gm of soap base and adjust according to your preference for future batches.
  6. Pour the liquid soap into the moulds. If using plastic moulds use a thin coat of vegetable oil to the inside of the moulds to assist removal. This is unnecessary if using silicone moulds. Spray the top of the soap with isopropyl alcohol to disperse any air bubbles that may have formed.
  7. Let the soap cool and harden completely before removing from the mould. Hardening takes several hours, depending on the day’s temperature.
  8. You can expedite removal, after letting the mould cool for about a minute, by covering your mould with plastic wrap and placing in a refrigerator. The soap usually hardens in 10 minutes and the soap can be removed by turning the mould over and applying gentle pressure to the back.

How to Make Melt and Pour Soap (Using a Microwave)

Instructions are similar to those for melting in a double boiler, except that you heat for 45 seconds to I minute on high depending on the amount of soap. Remove from the microwave and stir using the heat that the Pyrex jug has absorbed.

When the soap is no longer melting, microwave it again, at intervals of about 20-30 seconds, stirring until the soap base has completely melted.

Soap Making Tips

  • To calculate the amount of soap need for your mould, fill it with water and then pour into a measure.
  • If adding natural botanical ingredients to your soap, check that they are safe for your skin. Ensure you do not excess as this will make too scratchy and may even soften your soap. A few suggested natural that are being used in soap are citrus peel, coffee, cornstarch, honey, lavender, oatmeal, rose petals, rosemary, mica pigment powders and milk.
  • If you have any excess soap after filling our moulds, keep it for re-melting and adding to future projects. It is a good idea to always have an additional mould that you can fill during a casting session.

Safety Precautions

As soap melts at comparatively high temperatures 66°C for Glycerin soap base and 88°C for Coconut avoid contact with your skin while soap is liquid. If you happen to spill any on your skin, place the exposed area in cold water immediately.

Keep the melted soap away from children. Prevent overheating by checking at regular intervals. Avoid using plastic containers which may warp or collapse with high temperatures.

Additional Moulds

In addition to our stock plastic and silicone moulds, our resin range of moulds may also be used. These are self-releasing moulds and are ideal for creating something different.

High heat or micro-wavable plastic containers can also be used to make loaf style soaps. Check carefully to ensure that they can take the required heat and not melt and collapse. Do not use lightweight disposable plastic containers.

For regular use, there are wood moulds designed especially for loaf moulds that are safe and easy to use.
