Definitions

• This invention relates to clear stable single phase built liquid detergent composition.
• Normal powder detergents are a mixture of surfactants and inorganic builders in a ratio of about l:l to l:2. When these components are con­centrated into a liquid detergent form, there is a multiphase separation.
• liquid detergents have recog­nized and struggled with this incompatibility.
• the result has been that current commercial liquid laundry detergents are almost all surfactants with very little or no inorganic builders present.
• the inorganic builders are desirable because they are the lowest cost cleaning components in detergents.
• U.S. Patent No. 3,69l,l07 discloses a detergent composition comprising a mixture of one or more surfactants with a unique builder of compositions which comprises a cross-linked, water-insoluble copolymer of at least one C4-C10 olefin and at least one polycarboxyl vinyl monomer.
• the cross linked water insoluble copolymer is a water-swellable gel forming material.
• U.S. Patent No. 3,208,949 discloses ethylene maleic anhydrides and polyvinyl methacrylate maleic anhydride interpolymers for use in a heavy duty or built liquid detergent system. This patent discloses the use of a caprylic acid salt to function as a binary system to stabilize a built detergent into a substantially homogeneous pourable liquid deter­gent.
• U.S. Patent No. 3,830,745 depicts a de­tergent composition which includes anionic or non­ionic surface active agents and as a builder a novel water soluble salt of a copolymer of cyclopentene or its derivatives with maleic anhydrides. These cyclo­pentene maleic anhydride copolymers are hydrolyzed to an alkali metal salt to function as novel build­ers. The molecular weight of the copolymer is stated as 350 to 2000. This is a powder system.
• U.S. Patent No. 3,852,2l3 discloses chelat­ing compositions comprising 90 to 70% of polyvinyl methacrylate maleic anhydride copolymer and a 3 to 30% borax, detergent dyeing, scouring and similar compositions containing the ingredients and a process for chelating varies Group II and Group III metal ions.
• U.S. Patent No. 3,328,309 depicts a liquid detergent composition having a surface active deter­gent ingredient in a liquid medium.
• the detergent may be any commonly used surfactants of the nonionic and anionic types and mixtures thereof.
• the patent discloses the use of polymeric anhydrides having ethoxylated esters and anhydrides.
• the copolymers are all partial esters made by heating the anhydrides with ethoxylated or hydroxy containing surfactants to make partial esters.
• U.S. Patent No. 3,509,059 depicts a stable, heavy duty liquid detergent composition which con­tains high electrolyte content as a builder which is produced in a stabilized form by polymerizing to a polymer a monomer in the presence of the detergent material.
• the polymer acts as a stabilizer for the compositions.
• the composition is essentially a polymerization of an alpha, beta unsaturated car­boxylic acid to a surfactant. In other words, this is a polymer which is grafted onto a surfactants The acid has to be converted to salt first in order to have a functioning system.
• the object of this invention isto provide a clear homogeneous built liquid system which is neutral to slightly alkaline and which has good prespotter properties.
• the present invention provides a clear, stable, single phase built liquid detergent compo­sition, characterized by a) at least one nonionic surfactant in an amount of from about 5 to 25% by weight of the composition; b) a builder in an amount of from about 2 to 25% by weight of the composition; c) a water soluble polymeric anionic hydrotrope anti-redeposition agent in an amount of about l to l0% by weight of the composition, said hydrotrope being selected from the group of hydrolyzed alpha olefin maleic anhydride polymers, copolymers and ter­polymers having a carbon content of about C4 to C30+, and; d) the balance water wherein said composition has a pH in the range of about 6 to 9.
• the hydrolyzed alpha olefin maleic anhy­dride copolymer preferably has a carbon range from C4 to C18, and most preferably C6 to C10.
• the liquid laundry detergent is a heavy duty or built liquid detergent which is basically nonionic in nature and yet, is able to utilize borates, phosphates and carbonates as the main builders by the use of the hydrolyzed alpha olefin maleic anhydride copolymers.
• the hydrolyzed alpha olefin maleic anhydride co­polymers function as a hydrotrope to bring two dif­ferent phases of a normally two phase system into a single clear phase liquid detergent which has re­markable cleaning and prespotting properties when compared to the prior art liquid detergents and powdered detergents.
• Liquid detergents as a rule contain no builders or much lower concentrations of builders than powdered detergents. These builders, which are common in the art, are normally ionic, and by raising the concentration of ionics in solution, the nonionic surfactants of a liquid detergents tend to separate or phase out. In order to make up for the loss of detergency for lack of builders, liquid detergents must use higher surfactant levels.
• hydrolyzed alpha olefin maleic anhydride copolymers useful in the present invention have surprisingly been found to act as an excellent anti-redeposition agent as well as an ad­ditional builder which aids in the cleaning of the detergent. Accordingly, detergents formed according to the present invention have excellent prespotting and cleaning properties when compared with other liquid detergents as known in the art.
• the present invention is concerned with a clear, stable, single phase built liquid detergent composition which is able to use suprisingly large amounts of ionic builders.
• a water soluble polymeric anionic hydrotrope which is an alpha olefin maleic anhydride copolymer having a carbon content of about C4 to C30+, more preferably from C4 to C18 and most preferably from C6 to C10.
• the alpha olefin copolymers and terpoly­mers useful as a hydrotrope in this invention are made by the bulk process disclosed by U.S. Patent 4,358,573 and the solution process of U.S. Patent 4,522,992 incorporated herein by reference.
• the alpha olefin maleic anhydride poly­mers useful in the present invention are polymers of maleic anhydride and at least one l-alkene having about 4-30 carbon atoms and terpolymers with at least two different alpha olefins.
• the poly­mers are comprised of from about 49 to 80 mole percent of maleic anhydride and from about 20 to 5l mole percent of alpha olefin.
• the anhydride included in the alpha olefin maleic anhydride polymers is most preferably maleic anhydride.
• other maleic anhydrides can be utilized in this formation of the polymers such as methylmaleic anhydride, dimethylmaleic anhydride, fluoromaleic anhydride, methylethyl maleic anhy­dride and the like.
• maleic anhydride includes such anhydrides in whole or in part. It is preferred that the anhydride be substantially free of acid and the like before polymerization.

• alpha olefin maleic anhydride As is well known in the art, polymers containing equimolar ratios of alpha olefin maleic anhydride are essentially alternating polymers with maleic anhydride alternating between random comon­omers. Accordingly, the alpha olefin maleic anhy­dride polymers may contain from about 49 to 80 mole percent of maleic anhydride. Under some con­ditions such as high temperature and very high in­itiator levels, it is possible to include an excess of maleic anhydride relative to the comonomer in these polymers. The amount of alpha olefin will vary from about 50 to 20 mole percent. The optimum alpha olefin maleic anhydride polymers include about 50 mole % maleic anhydride and about 50 mole % alpha olefin.
