Dissolve PVP in ethanol. Add lanolin and heat slightly, if necessary, to effect solution. Add perfume oil. Allow to stand. Filter and charge with propellents.
To improve flexibility and reduce hygroscopicity of the PVP film, a compatible plasticizer, such as "Citroflex" A-2, dimethyl phthalate, glyceryl monoricinoleate, or oleyl alcohol may be added (10-25% based on resin solids). Suitable lanolin derivatives include "Acetulan" and "Amerchol" L-101, "Ethoxylan" 100, "Ethylan" and "Lanogel" 41, and "Lanethyl." |
