FACT FILES ON HANDMADE PURE, ORGANIC SOAP

How is soap made? Often when I’m stirring a batch of soap, I hear the words silently running through my head…”Double, double toil and trouble; Fire burn, and caldron bubble.” (from Macbeth, William Shakespeare)…some words stick with you for life!

So how do you turn an oil into a solid to create soap? There’s a bit of simple chemistry that applies to the process. Basically, a fatty acid/oil is combined with an alkali/caustic soda (NaOH) to form a solid/fatty acid salt…soap. The reaction that occurs: fat/oil + 3NaOH/sodium hydroxide = glycerine +3soap.

A fatty acid has a unique combination of triglycerides…compounds made of 3 fatty acids attached to a single molecule of glycerol. Glycerol is the basis of all fats, made up of a three carbon chain…connecting the fatty acids together. When mixed with the alkali solution with 1 hydroxide ion (the sodium ion does not take part in the reaction at all), the triglycerides within the fatty acid/oil release the single glycerol molecule…which turns into glycerine. The fatty acids combine with the hydroxide ions to form a solid soap salt.

This process is called ‘saponification’- the oil used as an ingredient becomes termed a ‘saponified oil’ for identification, or is identified as a salt- like sodium cocoate (saponified coconut oil). There is no other way to turn an oil into a solid salt. The caustic soda solution- sometimes termed ‘lye’- is part of the chemical process but, through the molecular reconfigurations in the equation, becomes inert and transforms the glycerol into the beneficial element of glycerine.

Glycerine is therefore created as a by-product of the soap-making process…making the use of caustic soda in the process a bit of a no-brainer for any concern, as it does not exist in the resultant soap. Glycerine is an incredibly moisturising substance- attracting moisture from its surroundings…a 'humectant'. It’s the most valued ingredient used in the skin care industry, and it is usually filtered off in commercial soap manufacturing to be used in moisturisers.

At ilo ORGANICS, we hand-make our soaps using the cold process method of soap manufacture. This method yields a high percentage of natural glycerine, and the glycerine quality in our soaps cannot be surpassed, as it is derived from processing pure organic plant oils. All handmade, cold process soaps can in fact be termed ‘glycerine soaps’ because of the high glycerine content produced as a by-product. 

After the mixture has thickened through careful blending, it is poured into moulds and left for a day to continue the saponification process and firm up. The formed soaps are then left to ‘cure’- evaporate the water content from the lye used, and further harden- for a period of weeks. This period is determined by the soap cake size and the oils used- varying from 4-8 weeks in our soap types produced.

At ilo ORGANICS, we ‘superfat’ our soaps. This means that in our soap recipe calculations, we make an allowance so that not all of the oils are converted in the processing. This leaves a percentage of the oils in their natural form to further moisturise the skin. These suspended oils can sometimes rise to the surface- causing small pockets of darker discolouration. The clear sticky coating that also rises to the surface of the soap is the glycerine content.

So if you were thinking that soap was the harsh product that commercial manufacturers now marketing body-washes in their economic drive would have you believe, think again. Handmade, cold process soaps are true soaps made with time-honoured traditions and natural ingredients- unsurpassed for the gentle, moisturising cleansing care that they offer the skin.

At ilo ORGANICS, our soaps also offer the added benefit of being made with pure organic plant oils, and are completely chemical, colouring and fragrance free. Indulge your body and nurture your skin naturally…you’ll wonder how you ever lived without our soaps- moisturising skin care in one simple step! Back to the stirring...
