Abstract
A fluid aqueous composition for cleaning an electric personal care apparatus including at least one alkyl benzene sulfonate and at least two non-ionic surfactants. The alkyl benzene sulfonate may be sodium alkyl benzene sulfonate. The non-ionic surfactants may be a fatty alcohol polyalkylene glycol ether and a fatty alcohol polyglycol ether.
Claims18
A system for cleaning debris from a portion of an electric personal care apparatus, the system comprising:
- a container for submerging the portion of the electric personal care apparatus;
- and
- a fluid aqueous composition provided in the container for providing sedimentation of the debris from the submerged portion to the bottom of the container, the fluid aqueous composition comprising:
- from at least 0.08 wt. % up to 3 wt. % of at least one alkyl benzene sulfonate for enabling sinking of the debris and comprising sodium alkyl benzene sulfonate;
- from at least 0.002 wt. % up to 3 wt. % of non-ionic surfactants including at least two non-ionic surfactants including at an alkylpyrrolidone and an alcohol-N-polyglycol ether, wherein N represents a number of glycol ether moieties and the alcohol is a monohydric alcohol;
- and
- polyethyleneglycol.
A method for cleaning an electric apparatus for removing hair debris, the method comprising acts of:
- providing a container for submerging a hair removing part of the electric personal care apparatus;
- providing a fluid composition in the container for providing sedimentation of the debris from the submerged portion to the bottom of the container, the fluid composition comprising:
- up to 98 wt. % of water,
- from at least 0.08 wt. % up to 3 wt. % of at least one alkyl benzene sulfonate for enabling sinking of the hair debris,
- from at least 0.002 wt. % up to 3 wt. % of non-ionic surfactants including at least two non-ionic surfactants including at least an alkylpyrrolidone and an alcohol-N-polyglycol ether, wherein N represents a number of glycol ether moieties and the alcohol is a monohydric alcohol, and
- polyethyleneglycol;
- allowing hair debris from the hair removing part of the apparatus to release from the removing part;
- and
- contacting the hair removing part of the electric apparatus in the container having the fluid composition.
A method for cleaning an electric personal care apparatus for removing hair debris, the method comprising acts of:
- providing a container for submerging a hair removing part of the electric personal care apparatus;
- adding a fluid composition in the container for providing sedimentation of the debris from the submerged portion to the bottom of the container, the fluid composition comprising:
- up to 98 wt. % of demineralized water,
- from at least 0.08 wt. % up to 3 wt. % of at least one alkyl benzene sulfonate for enabling sinking of debris and comprising sodium alkyl benzene sulfonate,
- from at least 0.002 wt. % up to 3 wt. % of non-ionic surfactants including at least two non-ionic surfactant(s) including at least an alkylpyrrolidone and an alcohol-N-polyglycol ether, wherein N represents a number of glycol ether moieties and the alcohol is a monohydric alcohol, and
- polyethyleneglycol;
- allowing hair debris from the hair removing part of the apparatus to release from the removing part;
- and
- contacting the hair removing part of the electric apparatus in the container having the fluid composition.
A system for cleaning debris from a portion of an electric personal care apparatus, the system comprising:
- a container for submerging the portion of the electric personal care apparatus;
- and
- a fluid aqueous composition provided in the container for providing sedimentation of the debris from the submerged portion to the bottom of the container, the composition is essentially free of organic solvents flammable at about 20° C. and comprising:
- up to 98 wt. % of water;
- from at least 0.08 wt. % up to 3 wt. % of at least one alkyl benzene sulfonate for enabling sinking of the debris and comprising sodium alkyl benzene sulfonate;
- from at least 0.002 wt. % up to 3 wt. % of non-ionic surfactants including an alkylpyrrolidone and a monohydric alcohol ether and 1-(octyl)-2 pyrrolidone;
- and
- polyethyleneglycol.
