DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an improved aqueous fabric cleaning shampoo composition containing a combination of a fabric cleaning polymer, a specific type of wax and a silicone betaine polymer in addition to at least one conventional surfactant to provide a fabric cleaning shampoo composition which not only provides good cleaning and conditioning to fabrics, particularly synthetic fibre fabrics, such as those used in carpets as well as to upholstery and pile fabrics, but also provides improved soil resistance to fabrics cleaned with such a composition.
BACKGROUND ART
Shampoo compositions for use on fabric materials such as carpets and upholstery have existed for a number of years. These types of products are used on fabrics that are large in size or fixed in place on furniture and thus cannot be easily removed from their current location for cleaning. In the case of carpets and rugs, these fabrics tend to receive high foot traffic and may get dirty rather quickly. Because of their size or location, such fabrics are not cleaned very often and thus it is beneficial to provide such fabrics with soil repellent treatments. Unlike articles of clothing that can be laundered in a clothes washing machine, the surfactants used to clean such fabrics cannot readily be rinsed from the fabric with water since the carpet or upholstery is fixed in place. Therefore there has been a constant desire to provide fabric cleaning compositions that can remove soil from carpets or upholstery with a minimum amount of water to speed drying of the fabric being cleaned while removing as much of the surfactants as possible since they tend to attract soil. Excess water can also cause shrinkage and warping of carpeting and may also promote mold growth. It is further desirable to have the cleaning composition impart anti-soiling properties to the fabric being cleaned to increase the time span between cleanings. Conditioning of the fabrics as a part of the cleaning process is also desirable.
Anti-soiling or soil repellency is described as the ability of a fabric such as a carpet to resist subsequent resoiling as a result of normal use such as foot traffic on carpets and ordinary use of furniture. It is a rough measure of the attraction or repulsion power of the products used to clean the fabric. Most carpeting and, often fabric furniture upholstery, is treated with a soil-resisting layer during the manufacture of the fabric or shortly before it is provided to the consumer. Examples of such treatments are the TEFLON.RTM. carpet treatment from E. I. Du Pont De Nemours & Company of Wilmington, Del., U.S.A. that is used in carpeting bearing the STAINMASTER.RTM. trademark and the SCOTCHGARD.RTM. products from 3M Company of St. Paul, Minn., U.S.A. which are used on both carpeting and fabric upholstery. Although these products render the fabric resistant to soiling, it is observed in many cases that the subsequent application of a shampoo fabric cleaning composition actively promotes the subsequent rate of resoiling of the cleaned fabric.
A number of attempts to provide shampoo fabric cleaning compositions have been made. U.S. Pat. Nos. 3,723,323 and 3,723,358 to Morgan et al. each describe aqueous fabric treating shampoo compositions containing anionic or nonionic surfactants as cleansing agents and neutralized polymers of acrylic or methacrylic acid with styrene or other unsaturated monomers such as alkyl acrylates and methacrylates. The polymer is said to impart anti-soiling properties to fabrics cleaned with the compositions. The composition is scrubbed into the fabric, allowed to dry, and then vacuumed away with the soil because the composition gets brittle and flakes away from the fabric fibres along with the soil upon drying. U.S. Pat. No. 4,013,595 to Podella et al. teaches non-flammable aqueous aerosol rug cleaners using hydrocarbon propellants. They possess reduced flammability due to the presence of at least 0.3% lauryl alcohol in combination with 0.3-10% of an alkali metal lauryl sulfate salt as at least one of the s
