I've been browsing for homogenizers for my home brewed cosmetics, for own (and family) use, so no need for special/expensive equipment.
I've come to the conclusion I might just as well use the stick blenders we already have (one of them I can keep for cosmetic use only). Point is, these are for large(r) quantities. Not for a 'batch' of 100 ml for example and I can't find tiny ones for sale.
It's not a problem if I have to make larger batches even if I need less, provided that I don't use expensive ingredients that need to be mixed.
Like hyaluronic acid, glucosamine, ferulic acid. These ingredients are about 10 dollars per gram here, so I can't afford the inevitable loss by using (large) blenders etc.
Does hyaluronic acid for example absolutely need to be sifted, and mixed by a homogenizer? Or can it be done by hand?
And what type of emulsions do absolutely require a homogenizer? For example, the ones with high oil concentrations, or depending on type of emulsifier, additions etc.
Many thanks again!
