Recently I have been asked the question “Can a laboratory liquid handling device such as bottle-top dispensers be used with oils in cosmetic formulation.” I have also been asked “What type of filter can I use for my cosmetic oils?”
Labmax bottle top dispensers can be used to deliver low viscosity oils. They must be frequently cleaned with hot soapy water to maintain them but they will greatly increase the precision in cosmetic formulation and they will control waste. The Labmax bottletop dispenser is a variable volume dispenser available in several ranges from 0.3ml to 100ml.
Whatman (now owned by GE Healthcare) makes several filtration devices which will aid in the filtration of low viscosity oils. The FilterCup™ is available with cellulose filter paper for fast or coarse filtration and it is also available with a glass microfiber filter for finer filtration. A filtration apparatus would consist of the FilterCup™, a one hole silicone stopper, A filtering flask, some vacuum tubing, and a laboratory vacuum pressure pump. It is possible to handle cosmetic oils professionally and efficiently without a laboratory.
