i've done some research (read the "setting up a cosmetic formulating lab" series and discussions on here, looked at blogs etc) but i'm still a bit lost as it relates to equipment, specifically stirrers/homogenizers. to start i'll be making body wash and body lotion and i'm not sure if i need an overhead stirrer, homogenizer or both. the way i understand it, most overhead stirrers have adjustable speeds and can do high shear AND low shear mixing but a homogenizer can only do high shear mixing so i'm better off with the stirrer, is this correct?
as i start experimenting i'll probably be working in small batches of maybe 200mL the most, until i'm satisfied with my base formula. should i use an immersion blender until i'm ready to scale up?
i've seen some overhead stirrers i think i like but i'm not sure what i'm supposed to be looking for in the first place, so if anyone has any advice, opinions or product recommendations they'd like to share i would love to hear them. i live in the caribbean so the easiest way for me to get things here is to purchase from US sites/companies and use a freight forwarder. paying freight and taxes can be expensive therefore my budget right now is $250. i do have amazon prime so recommendations from amazon are very welcome. thank you.
