Calculate How Much Soap to Use
1

Calculate how much soap you will need by measuring your mould (if you don't already know it's capacity).

The easiest way to do this is to put your mould on a set of scaled and press TARE. Now, fill the mould cavity with water and re-weigh your mould. Record this number.

If I measured 100g, then I would know I will need roughly 100g of soap for each cavity. If I have a loaf mould and I weigh 500g, I know that I'll need 500g of soap to fill it.

Calculate How Much Fragrance to Use
2

The amount of fragrance you will need is calculated based on how much soap you are using.

As a guide for how much to use:

Strong Scent: 3%
Medium Scent: 2%
Light Scent: 1%

If I am using 100g of soap, and I want a strong scent, I will use 3% of 100g fragrance.

Strong: 0.03 x 100g = 3g fragrance.
Medium: 0.02 x 100g = 2g fragrance.
Light: 0.01 x 100g = 1g fragrance.

If you don't have the equipment to weigh this out, you can use ml instead of g. It's not an exact match but is fine for smaller batches (under 1kg). This is much easier to measure out using a dropper/pipette.

Strong: 3ml fragrance.
Medium: 2ml fragrance.
Light: 1ml fragrance.

Weigh Your Soap Base
3

Weigh out your base into the pyrex jug. Do this by placing your jug on the scales and pressing TARE. Now, chop your base and place it into the jug on the scales until you've reached the required weight of soap.

Ensure your soap is chopped into 1-2cm cubes.

Melt Your Soap Base
4

Microwave Method: Microwave your soap in short bursts until it is completely melted (no chunks). For 100g use 10-15 second bursts. For 500g+ use 20-30 second bursts. Do not walk away - watch your soap and if it begins to bubble over stop the microwave immediately.

Double Boiler Setup: You can use a Pyrex glass measuring container or a stainless-steel pitcher set inside a pot of boiling water to melt your soap. Using a double boiler setup ensures that your MP Soap Base is not overheated during the melting process and not too much water is evaporated out.

Add Your Colour
5

Add your colour immediately, to avoid the base hardening again. Transparent bases will always give you a more vibrant colour, whereas white/opaque bases will give you a pastel colour.

Liquid Colour: Add your colour drop by drop to the melted base, until you're happy with the result.

Powdered Colour: Use around 1-2 teaspoons per 500g soap. Add your powdered colour to a very small amount of water or glycerine first and form a paste. Then, add it to your soap base and store well. This will avoid clumps.

Soap Colour Blocks: You can shave or chop your colour block into smaller pieces and add them slowly to your melted base until you reach the colour you're after. Stir them in until completely melted.

Glitter: Use 1-2 teaspoons per 500g soap base. Glitter and micas are best used in transparent soap bases, otherwise you will not be able to see the sparkle.

*A note about stirring your base: do not stir to vigorously as you will create bubbles. If you are not using isopropyl alcohol to disperse bubbles at the end, stir very gently and you shouldn't create too many.

**A note about vanilla content in fragrances - please check your fragrance oil for vanilla content. Vanilla will discolour your soap base brown over the following month, unless you use a vanilla colour stabiliser. Find it here:

Add Your Fragrance
6

Add your measured fragrance into the base immediately after the colour and stir to combine.

Pour the Base into the Mould
7

Place the mould in a safe position that won't be disturbed for at least an hour. It's helpful to place the mould on a chopping board - this will make it easier to move it around if you really need to.

Pour your soap base into the mould slowly and carefully.

Dispersing Bubbles (Optional)
8

Spray your soap with isopropyl alcohol to disperse bubbles. This isn't always necessary. It gives a better result in clear bases with embeds.

Un-moulding
9

If you are using a plastic (Milky Way or Life of the Party) mould, it helps to place the mould with soap in the freezer for 30 minutes prior to un-moulding.

You can also do this for silicone moulds if you are having issues or are worried about finger prints.

Carefully un-mould your soap onto a clean bench or chopping board.

*Important: Be patient! An extra 30 seconds spent carefully un-moulding your soap can make the difference between perfect soap and a bar with finger-prints. It will also reduce the likelihood of you breaking or cracking your mould.

Wrapping
10

Immediately wrap your soap in cling-wrap or cello bags and seal with sticky-tape or ribbon.

You can curl the ribbon and add a swing-tag for a more professional look.

*TIP: to get your soap into the cello bag without smudging the sides, use a business card to slide the soap in.
