- this invention is concerned with an improvement in a detergent composition
- a surface active agent is a member selected from the group consisting of anionic surface active agents and nonionic surface active agents and said builder is a watersoluble salt of a copolymer of cyclopentene or a loweralkyl-substituted derivative thereof with maleic anhydride.
- Detergent compositions are generally composed of a surface active agent and a builder for enhancing or promoting activity of the surface active agent, together with a smal amount of each of a restaining inhibitor, bleaching agent, fluorescent dye, sizing agent and the like.
- EDTA ethylenediaminetetraacetic acid
- NTA nitrilotriacetic acid
- STP sodium tripolyphosphate
- Such condensed polyphosphates show excellent builder effect, but they have 3,830,745 Patented Aug. 20, 1974 some drawbacks to be improved or overcome when used by incorporating them in a detergent composition.
- the polyphosphates when used by incorporating them in a detergent composition, are often converted into lower condensed polyphosphate compounds through hydrolysis in an aqueous solution thereof, which leads to loss of their activity as a builder and thus results in lowering the detergent activity of the detergent composition.
- liquid wastes containing such polyphosphate upon flowing into rivers and/ or sewerage, tends to promote the growth of duckweeds, resulting in environmental pollution as well as spoiling of the beauties of the nature.
- the other conventional inorganic or organic builders render poor detergent activity to a detergent composition containing them because of their inherently poor activity.
- This invention has been made upon the above finding and thedetergent composition of this invention is characterized in that it contains a Water-soluble salt of the PM resin or the PM resin derivative as a builder together with a surface active agent selected from the group consisting of anionic surface active agents and nonionic surface active agents.
- the water-soluble salts of the PM resin and PM resin derivatives which may be employed as a builder in this invention are all novel compounds, which are white powders.
- Preferred-examples of these salts include the corresponding alkali metal salts, e.g., sodium, potassium and lithium salt; and the corresponding ammonium salts.
- the PM resin and PM resin derivatives which are employable as a feedstock of the builder in this invention can be readily produced by copolymerization of cyclopentene or its lower alkyl-substituted derivative with maleic anhydride at a temperature of 50-150 C. in the presence of a radical polymerization initiator such as peroxide, e.g., benzoyl peroxide, azobisisobutyronitrile or the like and an organic solvent such as acetone, benzene or the like, as illustrated by the following reaction schema.
- a radical polymerization initiator such as peroxide, e.g., benzoyl peroxide, azobisisobutyronitrile or the like

- R represents a hydrogen atom or a lower alkyl group, preferably of l to 5 carbon atoms, e.g., methyl, ethyl, n-prop'yl, isopropyl, n-butyl, sec.-butyl,
- the PM resin and PM resin derivatives thus obtained are white powders and have an average molecular weight of 350-2,000 and a softening point of 200-260 C.
- the cyclopentene or its lower alkyl-substituted derivative, employed can be produced through hydrogenation of cyclopentadiene or its lower alkyl-substituted derivative, for example by the use of a nickelcontaining catalyst and gaseous hydrogen.
- the water-soluble salts of the PM resin or PM resin derivative can be produced by reacting the PM resin or PM resin derivative obtained as above with alkali, for example, an aqueous solution of alkali metal hydroxide, ammonium hydroxide or alkali metal carbonate as illustrated by the following reaction schema.
- R and n are as defined above, M represents an alkali metal atom, e.g., sodium, potassium or lithium or an ammonium ion and M represents an alkali metal atom, e.g., sodium, potassium or lithium.
- the aqueous solution to be employed may be of a concentration up to saturation, but may be usually of a concentration of 20-50% by weight for alkali metal hydroxide and ammonium hydroxide and of a concentration of saturation for alkali metal carbonate.
- the alkali metal hydroxide, ammonium hydroxide or alkali metal carbonate may be employed in an amount equivalent to that of maleic anhydride component of the PM resin and PM resin derivative.
- the reaction is conducted, while stirring, at room temperature for about 30 minutes to obtain a transparent reaction mixture.
- the reaction temperature may advantageously be elevated to 120-130 C., for shortening of the reaction period.
- the resulting reaction mixture is then subjected to distillation under reduced pressure and/or with heating (up to 120- 130 C.) to remove water therefrom. As a result, there is deposited a desired water-soluble salt of the PM resin or PM resin derivative.
- the product is white powders and its aqueous solution has an alkalinity of pH 9-10 at a concentration of 0.05% by weight.
- anionic surface active agents which may be employed in the detergent composition of this invention are, for example, sodium linear alkyl-benzenesulfonates (hereinafter referred to as LAS), sodium a-olefin sulfonates (hereinafter referred to as AOS), sodium 'alkylbenzenesulfonates (hereinafter referred to as ABS) and the like.

- the water-soluble salt of the PM resin or 'PM resin derivative may be employed, as a builder, alone or in mixture with the other compound useful as a builder.
- the inorganic builders such as STP which have some drawback can advantageously be employed in a reduced amount by employing the present novel builder together therewith.
- the detergent composition of this invention may be produced simply by mixing the components, i.e. a surface active agent, the present water-soluble salt and additives such as a restaining inhibitor, 'bleaching agent and the like.
- the present water-soluble salt may be incorporated in an amount usually employable in respect of the conventional builder, namely, in an amount of 10-90% by weight, preferably 40-60% by weight based on the detergent composition.
- the detergent composition of this invention shows a high detergency as demonstrated by the following examples.
- a washing efficiency D was determined according to the general detergency test procedure as set forth below:
- Pieces of cotton broad cloth (yarn count #60) were subjected to desizing and then stained artificially by keeping them in contact with skin of person to prepare naturally stained cloths.
- the test cloths thus prepared were washed for 10 minutes in a tergotometer at 25 C. with a bath ratio (grams of cloth/grams of aqueous solution of detergent) of 30.
- reflectivity of test cloth prior to staining Ro reflectivity of stained test cloth prior to washing Rs and reflectivity of stained test cloth after washing Rw were measured, respectively, and from the values thus measured the washing efficiency D (percent) was calculated according to the equation;
- EXAMPLE 1 (1) Preparation of the PM resin 0.5 M01 (34 g.) of cyclopentene, 0.5 mol (49 g.) of maleic anhydride, 1 g. of benzoyl peroxide and 100 ml. of acetone were charged in a glass-made autoclave havinga capacity of 200 ml. The reaction was allowed to proceed at 80 C. for 2.5 hours. After completion of the reaction, the reaction mixture was cooled and then precipitated from methanol, followed by filtration and drying to give 65 g. of the PM resin which was white powders and had an average molecular weight of 1,500 and a softening point of 250-260 C.
- EXAMPLE 2 1) Preparation of methyl-PM resin 1.0 M01 (82 g.) of methylcyclopentene, 1.0 mol (98 g.) of maleic anhydride were dissolved in 200 ml. of benzene and 3.6 g. of benzoyl peroxide were then added. The reaction was allowed to proceed at 80 C. for 2.5 hours, while stirring. It was observed that viscosity of the reaction system increased with progress of reaction. After completion of the reaction, the reaction mixture was cooled to room temperature and then added in 360 g. of
- methyl-PM resin which has an average molecular weight of 1,600 and a softening point of 200-230 C.
- EXAMPLE 3 (1) Preparation of n-propyl-PM resin The substantially same procedure as described in (1), Example 2 above was repeated except that equimolar amounts of n-propylcyclopentene and maleic anyhdride were employed. The thus obtained product was white powders and had an average molecular weight of 1,750 and a softening point of 185200 C.
- EXAMPLE 4 (1) Preparation of ethyl-, isopropyl-, n-butyland n-pentyl-PM resins The substantially same procedures as described in 1) of Example 1, 2 or 3 were repeated except that the corresponding derivatives of cyclopentene to the above substituents were employed in an equimolar amount of that of maleic anhydride. The results are shown in the following Table 1.
- EXAMPLE 5 Detergency test was made according to the aforementioned general procedure with r.p.m. of the meter by the use of LAS as anionic surface active agent, POENE-8 as nonionic surf-ace active agent and watersoluble salts of PM resin and PM resin derivatives (which are polyelectrolytes) and sodium tripolyphosphate as builder and, after washing, test cloths were squeezed to remove moisture and then dried at room temperature. Formulation of each test detergent liquid is given below.
- Nora-C shows a reference example, a comparative example and an example concerned with the present invention, respectively. shows weight percent based on the aqueous solution of detergent composition.
- sodium salt of PM resin exerts, as such, detergency to some extent and a detergent composition having the present water-soluble salt incorporated therein as a builder for the surface active agent LAS or POEN'E-80, shows an excellent detergency, especially more remarkable in soft water. Even in highly hard water can be noted the same or higher degree I 7 of washing efficiency with the present detergent composition.
- novel water-soluble salts of the described copolymer are stable in the form of an aqueous solution and have a practically satisfactory non-irritating property on skin and an excellent antistatic eflFect on the washed ma terials as Well as a superior inhibiting effect on restaining.
- the PM resin and PM resin derivatives are inexpensively avail-able due to recent development of petrochemical industries.
