Abstract
Aerosol compositions containing fluorinated oils are disclosed. At least one fluorinated component compatible with the fluorinated oil and a propellant are included in the aerosol composition. Fluorinated oil-containing non-aerosol compositions are also disclosed. In a particularly desirable form, the compositions are single-phase.
Claims30
An aerosol composition comprising:
- a) a fluorinated oil;
- b) at least one fluorinated component selected from the group consisting of fluorinated alkanes having from 4 to 10 carbon atoms, fluorinated ether compounds corresponding to the formula R1OR2 wherein R1 and R2 may be the same or different and are fluorinated alkyl groups having from 1 to 4 carbon atoms, and combinations thereof, wherein said fluorinated component is compatible with said fluorinated oil;
- and
- c) a propellant, wherein the ratio of said fluorinated oil to said fluorinated component provides a non-icing film when sprayed in ambient conditions.

A fluorinated oil composition capable of forming a non-icing aerosol comprising:
- a) a fluorinated oil;
- and
- b) at least one fluorinated component selected from the group consisting of fluorinated alkanes having from 4 to 10 carbon atoms, fluorinated ether compounds corresponding to the formula R1OR2 wherein R1 and R2 may be the same or different and are fluorinated alkyl groups having from 1 to 4 carbon atoms, and combinations thereof, wherein said fluorinated component is compatible with said oil, and further wherein the ratio of fluorinated oil to fluorinated component is about 1:0.5 to about 1:15.
An article of manufacture comprising:
- a) a container for packaging a flowable composition;
- b) a flowable composition within said container, said composition comprising:
- i) a fluorinated oil;
- ii) at least one fluorinated component selected from the group consisting of fluorinated alkanes having from 4 to 10 carbon atoms, fluorinated ether compounds corresponding to the formula R1OR2 wherein R1 and R2 may be the same or different and are fluorinated alkyl groups having from 1 to 4 carbon atoms, and combinations thereof, wherein said fluorinated component is compatible with said oil;
- and
- iii) a propellant,
- wherein said composition is non-icing when sprayed from said container in ambient conditions.
4 more elements
A method of preparing a non-icing fluorinated aerosol composition comprising:
- a) providing a fluorinated oil;
- b) providing a fluorinated component compatible with said oil, wherein said fluorinated component is selected from the group consisting of fluorinated alkanes having from 4 to 10 carbon atoms, fluorinated ether compounds corresponding to the formula R1OR2 wherein R1 and R2 may be the same or different and are fluorinated alkyl groups having from 1 to 4 carbon atoms, and combinations thereof
- c) combining said fluorinated oil with at lease one said fluorinated component;
- and
- d) further combining the resultant combination with a propellant;
- wherein the ratio of fluorinated oil to fluorinated component is about 1:0.5 to about 1:15.
