Method
(Work in a well ventilated area, put on your dusk mask and turn on the extractor fan if you have one, the SCI fumes are very unpleasant at the beginning.)
- Melt Phase A ingredients in a pot on the stove. Once it's starting to melt, blend with a stick blender to speed up the process and get a smoother finished bar. Blend until the mixture comes together to form a paste-like consistency.
- Take the pot off the heat and blend in Phase B ingredients.
- Using a spatula, pour the mixture into moulds Smooth top over with a knife. It can be difficult to get a clean finish so don’t worry if it’s a bit rough looking, its got that lovely homemade rustic look.
- Pop them in the fridge to set.

About the ingredients
Some of these ingredients may be unfamiliar so here's a quick summary of what they are and what they do.
SCI (sodium cocoyl isethionate) - a coconut oil-based surfactant. It is very mild on skin, hair and eyes and has a silky skin feel. SCI makes a great lather and is good for making liquid shampoos and solid shampoo bars.
Conditioner pellets (aka BTMS-25) - Derived from rapeseed oil and palm oil (RSPO mass balance certified), these pellets make a luxurious hair conditioner (the best we've ever come across) and hair detangler for leave-on and rinse-off products.
Decyl glucoside – one of the first of the alkyl polyglucoside (APG) surfactants. APG surfactants are obtained from renewable, plant-derived raw materials, such as vegetable oils and starch. They have first-rate environmental and skin compatibility profiles and fit in well with consumer demands for wellness, 'green solutions', mildness to human skin, and safety for human health.
Lactic acid - Our lactic acid is produced from fermented corn. It is used to make a harder and longer-lasting bar and has excellent exfoliant, moisturising and deep cleansing properties.
Hydrolysed wheat protein – derived from wheat germ it is used to increase hydration and elasticity, protect cuticles and strengthen hair. Because of its low molecular weight, it easily penetrates the hair shaft and absorbs into the inner fibres of the hair.
Coco Caprylate – a skin-conditioning agent naturally derived from coconut oil to provide hydration, spreadability and slip.
Geogard 221 - Ecocert approved, broad spectrum preservative.
