NAME OF THE ACTIVITY: Natural Handmade Soap

LEVEL: 3

DESCRIPTION: Cold process soap is scented with essential oils and coloured with botanical elements, has no additives that are bad for the environment and is gentle on sensitive skin. Most soap bars have detergents but no soap. Soap goes through the saponification process, converting fats, oils, lye and water into soap and glycerine. After that chemical process is complete, the soap is safe to use and gentle on skin. There are many methods for creating soap from scratch: cold process, hot process, milk soap and rebatching. You can also make it melt and pour soap at home to mix extra ingredients into it. Don’t forget to use protection when making soap, as lye can burn your skin.

MATERIAL REQUIRED:

Rubber gloves

Safety goggles

Protection Mask

Kitchen Scale

Spatula

Candy thermometer

Stainless-steel pot

Stove or microwave

Milk cartons

Natural colorants (at your preference)

Herbs (at your preference)

Exfoliants (if you like, at your preference)

Pyrex measuring cup (Heat resistant glass bowl)

Oils:

207 ml (7 oz) of coconut oil

502 ml (17 oz) of olive oil

60 ml (2 oz) of grapeseed oil

Lye mixture:

78 g of sodium hydroxide (NaOH)

215 g of filtered water

 

Instructions:

Step 1 – Prepare everything that you will need and set it out accessibly before you begin.

Step 2 – Soap making measurements are done in weight, not volume, so be sure you have a good kitchen scale and weigh all the ingredients.

Step 3 – Put on your protection and keep your work area free from kids and pets.

Step 4 – Gently and slowly heat the oils in a stainless-steel pot on the stove. Or use a microwave and heat for two minutes on high, and then at shorter intervals, until you reach 46°C (115°F). Use a candy thermometer to check the temperature.

Step 5 – Using room-temperature distilled water, weigh the 78 grams of Sodium hydroxide and the 215 grams of filtered water into a heat resistant glass bowl, or large Pyrex measuring cup. While stirring, slowly add the measured amount of lye. Stir until dissolved. This mix will get hot super-fast so be careful. The fumes are powerful, so don’t forget your mask and to open a window, or do this outdoors.

Step 6 – Place the Pyrex in an ice-water bath and cool to room temperature. Use a candy thermometer to check the temperature of the solution.

Step 7 – When both oils and lye/water are at the required temperatures, slowly pour lye/water into the oils while rapidly stirring in small circles. Always add lye/water to oil, not the other way around.

Step 8 – Continue to rapidly stir the mixture until it thickens to the consistency of pudding (called “tracing”). The mixture is ready to be moulded when a drizzle mark from the spatula remains for a few seconds on the top of the mixture. You can speed up the tracing by using a hand blender to mix, but be careful not to overdo it.

Step 9 – Add essential oils, natural colorants and herbs or exfoliants at this stage. (See specific scent recipes below). Work fast as the mixture will quickly start to thicken. There are many options for colouring and scenting soap, but avoid perfumes, fragrance and artificial colours, as the pure essential oils and natural coloured dyes are better for your skin.

Step 10 – Pour the mixture into milk cartons and staple the tops shut. Wrap the cartons in a large towel and set somewhere warm for 48h (i.e. the top of the fridge). The cartons will feel warm and will get hot as the mixture neutralizes and turns into soap.

Step 11 -  To unmould your soap, peel off the milk carton and cut each full 1-liter carton lengthwise into 3 equal sections for shower soap, and 4 equal sections for hand soap. Flip each section so that it appears to be a square from the top and cut into 3 equal sections.

Step 12 -  Place each bar on a wire rack in a cool dark place to cure for 3 weeks. After three weeks, soap can be buffed with a cotton cloth and wrapped for gifts or use.
