Abstract
The disclosure includes synergistic combinations of pendent alkyl siloxanes and PEG-modified castor oils which can form microemulsions and foam in low surface tension solutions. The foaming compositions may form foam in water, alcohol/water, and hydrocarbon condensates. The foaming compositions may replace surfactants in other compositions and forms stable emulsions or microemulsions with oils, including non-trans fats proteins, and fatty acids. The disclosure also includes sterilizing alcohol compositions, cleaning compositions, such as hard surface cleaners, warewash detergents, rinse aids and the like which incorporate the same.
Claims41
A foaming surfactant combination capable of reducing surface tension of a water ethanol mixture comprising:
- from about 0.2 to about 0.3 wt. % of a pendent alkyl siloxane;
- and
- from about 0.05 to about 0.07 wt. % of a PEG-modified castor oil comprising 20-60 moles of PEG in an ethanol/water solvent mixture comprising from about 62% to about 98% of ethanol.
A method of hand and hard surface sanitizing, surface cleaning, including rinsing, removing protein, and/or nontransfats through the formation of an emulsion or microemulsion comprising:
- applying to a surface having said protein or nontransfat, a cleaning composition/rinse aid comprising:
- from about 2 to about 3 wt. % of a pendent alkyl siloxane;
- and
- from about 0.05 to about 0.07 wt. % of a PEG-modified castor oil comprising 20-60 moles of PEG in an ethanol/water solvent mixture comprising from about 62% to about 98% of ethanol.
A hand sanitizer, hard surface sanitizer or surface cleaning composition comprising:
- a foaming component, wherein the foaming component comprises
- a) a pendent alkyl siloxane;
- and
- b) a PEG-modified castor oil in an ethanol/water solvent mixture comprising from about 62% to about 98% ethanol.
