CM-23 e ~ 337107 CRE~MY SCOURING COMPOSITIONS CONT~INING
S~TUR~TED TERPE~E SOLVENT
Technical Field The present in~ention relates to uiscous abrasi~e-containing scouring compositions, which show excellent stability, exhibit uery good cleaning and shine performance, and are not aggressiue towards surfaces to be cleansed therewith, and towards packaging materials.
The compositions are substantially free of unsaturated terpene sol~ents, but contain a saturated terpene sol~ent.
Background It is well-known to formulate scouring compositions, in liquid or creamy form, containing soluents.
In particular, creamy scouring compositions containing an abrasiue and a binary soluent system constituted of unsaturated terpenes and polar soluents haue been disclosed in European Patent ~pplication 0,126,545, published on Nouember 28, 1984. In these compositions, the terpenes both prouide cleaning benefits and exhibit desirable emulsification properties during the making process thus enhancing product uiscosity.
It has become desirable, howe~er, to replace unsaturated terpenes by soluents which are fully compatible with all types of surfaces to be cleansed therewith, and packaging materials, and at the same time exhibit good cleaning and emulsification properties.
It has now been found that the use of saturated terpene soluents in replacement of the unsaturated counterparts, prouides the desired compatibility with packaging material, while maintaining ~ery good cleaning, shine performance, and product uiscosity.
In addition, the use of saturated terpene sol~ents brings improuements in terms of product stability and odor quality.
U.S. Patent 4,576,738 discloses liquid hard-surface compositions containing ,aturated terpenes in combination with a water-soluble soluent.
~337107 The prior art, howeuer, fails to disclose or suggest the formulation of ~iscous, abrasi~e-containing, scouring compositions containing saturated terpenes.
It is an object of the present inuention to prouide uiscous creamy cleanser compositions which are fully compatible with surfaces to be cleansed therewith and with packaging materials. It is a further object of the present inuention to prouide a cleanser composition with excellent cleaning and shine performance.
Summary of the Inuention The present inuention relates to a uiscous creamy scouring compositions containing a surface-actiue agent, an abrasiue, and an organic soluent and if desired conuentional additiues, characterized in that said cleanser is substantially free of unsaturated terpene soluents and that the organic soluent contains a saturated terpene hydrocarbon.
Detailed Description of the Inuention The surface-actiue agents, the abrasiues, the soluent and the optional ingredients are described in more detail hereinafter.
Unless indicated to the contrary, the X-indications stand for "X by weight".
Surface-actiue ~ents Water-soluble detersive surfactants useful herein include well-known synthetic anionic, nonionic, amphoteric and zwitterionic surfactants and mixtures thereof. Typical of these are the alkyl ben~ene sulfates and sulfonates, paraffin sulfonates, olefin sulfonates, alkoxylated (especially ethoxylated) alcohols and alkyl phenols, amine oxides, sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known in the detergency art In general, such detersiue surfactants contain an alkyl group in the C10-Cl8 range; the anionic detersiue surfactants are most commonly used in the form of their sodium, potassium or triethanolammonium salts. The nonionics generally contain from 3 to 17 ethylene oxide groups per mole of hydrophobic moeity Especially preferred in the compositions of the present inuention are:
C12-C16 alkyl benzene sulfonates, Cl2-C18 -;
paraffin-sulfonates and the ethoxylated alcohols of the formula RO(CH2C~20)n, with R being a C12-C15 alkyl chain and n being a number from 6 to 10.
~ nionic surfactants are frequently present at leuels from 0.3 to 8~, preferably 2 to 4%, of the composition.
Nonionic surfactants, are used at leuels between 0.1~ to 6~
by weight of the composition. Mixtures of the like surfactants can also be used. The total leuel of surface-actiue agents is preferably from 3~ to ~%.
~brasiue - The abrasiue types employed herein are selected from water-insoluble, non-gritty materials well-known in the literature for their relatiuely mild abrasiue properties.
It is highly preferred that the abrasiues used herein not be undesirably "scratchy". ~brasiue materials hauing a Mohs 13~7 1~
hardness in the range of about 7, or below, are typically used; abrasives hauing a Mohs hardness of 3, or below, can be used to auoid scratches on aluminum or stainless steel finishes. Suitable abrasiues herein include inorganic materials, especially such materials as calcium carbonate and diatomaceous earth, as well as materials such as Fuller's earth, magnesium carbonate, China clay, attapulgite, calcium hydroxyapatite, calcium orthophosphate, dolomite and the like. The aforesaid inorganic materials can be qualified as "strong abrasi~es". Synthetic organic abrasi~es such as urea-formaldehyde, methyl methacrylate melamine-formaldehyde resins, polyethylene spheres and polyuinylchloride can be ad~antageously used in order to auoid scratching on certain surfaces, especially plastic surfaces. When such "soft abrasives" are used, strong builders can be incorporated in the composition.
Typically, abrasiues haue a particle size range of 10-200 microns and are used at concentrations of 5% to 30%
in the compositions. Thickeners are frequently added to suspend the abrasi~es.
The organic solvent - The organic sol~ent to be used in the present composition contains saturated terpene hydrocarbons.
Saturated terpenes for use herein include the hydrogenated species corresponding to well-known mono- or sesquiterpenes, which can be acyclic or cyclic.
Preferred materials for use herein are the hydrogenated mono- and bicyclic monoterpenes, selected from hydrogenated terpinenes, terpinolenes, limonenes, and pinenes.
~ highly preferred material is hydrogenated pinene, also known as pinane or 2,6,6-trimethyl bicyclo (3.1.1.) heptane.
The saturated terpene hydrocarbon herein is used at leuels of from lX to 10~ by weight of the composition, preferably 1.5X to 5X by weight.
The soluent system can optionally contain polar soluents in combination with the saturated terpene component, in order to further improve cleaning performance. This includes polar soluents with low water solubility, like benzyl alcohol, and diols such as 2-ethyl~ -hexanediol and 2,2,4-trimethyl-1,3-pentanediol, and soluents with high water-solubility, like water-soluble C~RBITOL soluents or water-soluble CELLOSOL~E soluents. Water-soluble C~RBITOL soluents are compounds of the 2-(2-alkoxyethoxy)ethanol class wherein the alkoxy group is deriued from ethyl, propyl or butyl; a preferred water-soluble carbitol is 2-(2-butoxyethoxy)ethanol also known as butyl carbitol. Water-soluble CELLOSOL~E
soluents are compound of the 2-alkoxyethoxy ethanol class, with 2-butoxyethoxyethanol being preferred.
Preferred for use herein is benzyl alcohol.

to 5X, the weight ratio of saturated terpene to polar soluent being in the range from 5:1 to 1:~, preferably 2:1 to 1:2.
The compositions herein are substantially free of unsaturated terpene-solvents. Inasmuch as solvents are generally used at leuels exceeding about 2X, unsaturated terpenes cannot be incorporated in the claimed compositions in such proportions. It is understood, however, that relatiuely minor sub-additive leuels of unsaturated terpenes, e.g., below about 0.6% (calculated on the total cleanser composition), can be present originating from conuentional ingredients such as perfumes.
Optional Ingredients - In addition to the essential ingredients listed hereinbefore, the present composition can contain additional components, which can be highly desirable.
For example, the compositions herein can contain a detergent builder and/or metal ion sequestrant.
