Abstract
A composition is provided for a non-aqueous foaming aerosol cleaner or lubricant. Foam builders, especially silicone glycol copolymers, are used to generate high density foam of the solvent-based formula. A cleaning product variant may be introduced via an air intake route for loosening deposits in an internal combustion engine. The high foam aerosol product dispenses easily without causing engine stalling. A process of lubricating a target substrate is also provided.
Claims17
A non-aqueous foaming aerosol composition, said composition comprising:
- a foam builder that is a silicone glycol copolymer that soluble in water, alcohol, and hydro-alcoholic systems, silicone glycol copolymer having a weight average molecular weights in the range 30-30,000;
- viscosity in the range of 5-4,000 cSt;
- and siloxane content of 10-80%;
- one or more non-aqueous solvents in which said foam builder is dissolved or dispersed;
- an active component of cleaning agent or a lubricant;
- and
- a propellant to aerosolize said foam builder and said one or more non-aqueous solvents.
