I am starting a small cosmetic lab in the south of Morocco, where we aim to produce natural, raw skin cosmetics using local products. The main range would be specialty oils, hydrosols, liquid soap.
I am having quite a hard time figuring out the equipment needed for this. We will be having a liquid soap making line, a product mixing line and a filling line.
1) Liquid soap line : for a starter we want to make no more than 100liters of liquid soap per month. I don't want to invest in an industrial soap making machine as they can be very expensive. I can however make it in small batches using a water jacketed tank (for heating oils and the saponification process) : I was thinking of using a big soup kettle for this, as I think it's somehow safer than a bain-marie. Do you think this is a good idea? Any suggestion on what can I use otherwise?
For the mixing, I was thinking of an heavy duty overhead blender (like the one used in professional kitchens)
2) Product mixing line : For the all-oil product and all-hydrosol products, I was wondering if a Mixer with a whisk would be enough to have a good stable blend.
For the balms, where I will be using beeswax, should I need the mixing tank to be heated too? Can't I be pouring liquid wax with mixing medium/high shear enough? or the beeswax would not allow this? In the case of a heated mixing, my concern when it comes to professional water bath is that the tank used have corners and I fear the mixing would not be good. Can I then be using also here a soup kettle? We are talking here about no more than 50 liters a month (Yes we are starting very small
3) Filling line : We would want a manual filling machine for liquid products with low viscosity (oils and waters) and more viscosity product as shampoo and liquid soap and balms. The filling weight would go from 5g to 250g. Do you have a suggestion on this? The bottles and jars will be in glass and plastic with different screw caps.
As we are starting small, I am trying to purchase good material but lower the price as much as possible. It would be amazing if you could share you recommendations and advices, but also your own experience on this topic.
Thank you for your feedbacks.
