ABSTRACT:
FIELD OF THE INVENTION
The present invention provides a blooming pine oil cleaning composition. The present invention also provides a method of cleaning a surface using the disclosed pine oil cleaning composition.
BACKGROUND OF THE INVENTION
Water-soluble cleaning compositions are commercially important products and enjoy a wide field of utility in assisting in the removal of dirt and grime from surfaces; especially those characterized as useful with “hard surfaces”. One particular category of aqueous cleaning compositions are those which provide a “blooming” effect upon being added to water. Such an effect may be described as the change of the water's appearance from essentially colorless and transparent to that of a milky white or milky yellowish white, cloudy appearance upon the addition of an amount of the cleaning composition. This effect is also sometimes referred to as the “break”. Such blooming is highly desirable in such pine oil type water-soluble cleaning compositions as consumer/end user associates cleaning effectiveness with the extent and degree of this blooming upon formation of a cleaning composition. Such an effect is particularly known and generally associated with pine oil type water-soluble cleaning compositions which typically include one or more of the following identifying characteristics: containing an amount of one or more resins or oils derived from coniferous species of trees; containing natural fragrances or synthetic fragrance compositions which are intended to mimic the scent of one or more resins or oils derived from coniferous species of trees; a color ranging from colorless to a deep amber, deep amber yellow or deep amber reddish color; generation of a milky or cloudy appearance when diluted with water in dilutions useful for cleaning applications. Such pine oil type cleaning compositions are generally provided in a concentrated composition which is subsequently diluted with water by an end user/consumer to form a cleaning solution therefrom.
Another important characteristic of pine oil cleaning compositions is phase stability. The composition should be clear and phase stable at temperatures of normal use and storage, before being further diluted with water. There is thus a need for a water-soluble pine oil cleaning composition that possesses the characteristics of phase stability, blooming, and efficient cleaning properties. The present invention provides such a cleaning composition. The present cleaning composition further has the attribute of providing synergistic detergency/cleaning effects resulting from the combined use of the cationic, anionic and nonionic surfactants present in the claimed cleaning compositions.
U.S. Pat. No. 4,414,128 discloses an aqueous liquid detergent composition comprising: (a) from 1% % to 20% of surfactant selected from synthetic anionic, nonionic, amphoteric and zwitterionic surfactants and mixtures thereof; (b) from 0.5% to 10% of terpene selected from mono- and sesquiterpenes and mixtures thereof, the weight ratio of surfactant:terpene lying in the range from 5:1 to 1:3 and (c) from 0.5 to 10% of a polar solvent having a solubility in water at 25° C. in the range from 0.2% to 10%, said polar solvent being selected from the group consisting of benzyl alcohol, polyethoxylated phenols containing from 2 to 6 ethoxy groups, phenylethyl alcohol, mono C

DETAILED DESCRIPTION OF THE INVENTION
In addition to A) water, the liquid pine oil cleaning composition of the present invention comprises B) 5 to 20% (of total composition weight), and in one embodiment 5-10%, in one embodiment 10-15%, and in one embodiment 15-20% by weight of pine oil.
Pine oil is an organic solvent, and is a complex blend of oils, alcohols, acids, esters, aldehydes and other organic compounds. These include terpenes which include a large number of related terpene alcohols and terpene ketones. The terpenes include mono- and sesquiterpenes or mixtures thereof.
Preferred terpenes are mono- and bicyclic monoterpenes, especially those of the hydrocarbon class, which can be selected from terpinenes, terpinolenes, limonenes and pinenes. Highly preferred materials of this type include d-limonene, dipentene, &agr;-pinene, &bgr;-pinene and the mixture of terpene hydrocarbons obtained from the essence of oranges (e.g., cold-pressed orange terpenes and orange terpene oil phase ex fruit juice).
An important terpene alcohol is terpineol, which is one of three isomeric alcohols having the basic molecular formula C

OH. One type of pine oil, synthetic pine oil, will generally have a specific gravity at 15.5° C. of about 0.9300, which is lower than the two other grades of pine oil, namely steam distilled and sulfate pine oils, and will generally contain a higher content of turpentine alcohols. Other important compounds include abietic acid (rosin), and other isoprene derivatives.
Particularly effective pine oils which are presently commercially available include Unipine® 60 (from Union Camp, which is believed to contain approximately 60% terpene alcohols), Unipine® S-70 and Unipine® S-70 (from Union Camp, both are believed to contain approximately 70% terpene alcohols), Unipine® S and Unipine® 80 (from Union Camp, both are believed to contain approximately 80% terpene alcohols), Unipine® 80 (from Union Camp, which is believed to contain approximately 80% terpene alcohols), Unipine® 85 (from Union Camp, which is believed to contain approximately 85% terpene alcohols), Unipine® 90 (from Union Camp, which is believed to contain approximately 90% terpene alcohols), as well as Alpha Terpineol 90 (from Union Camp, which is believed to contain approximately 100% terpene alcohols). Further effective pine oils include Glidco® Pine Oil™ 60 (available from Glidco Organics Corp., Jacksonville, Fla., believed to contain approximately 60% terpene alcohols), Glidco® Pine Oil 60 (available from Glidco Organics Corp., Jacksonville, Fla., believed to contain approximately 60% terpene alcohols); Glidco® Pine Oil 140 (available from Glidco Organics Corp., Jacksonville, Fla., believed to contain approximately 70% terpene alcohols); Glidco® Pine Oil 80 (available from Glidco Organics Corp., Jacksonville, Fla., believed to contain approximately 80% terpene alcohols) Glidco® Pine Oil 150 (avai
