Definitions
- the subject matter of this invention relates to liquid laundry detergent compositions which contain alkyl-or alkenyl-succinates, in combination with citrates, as detergency builder ingredients.
- UK 1.293.753 describes solid laundry detergent compositions preferably comprising 20 % to 40 % of such succinates as builders.
- carboxylate materials of various types in solid and liquid cleaners are well-known; see UK 1.514.276 for amine soap mixtures; UK 1.429.143 for zeolite/polycarboxylate mixtures: US 2.264.103 for citrate and other carboxylate plus soap mixtures; US 3.634.392 for polysaccharidic carboxylate detergency builders; US 3.898.187 for various sulfur-succinates in dishwashing detergents; and UK 1.400.898 for use with clay softeners.
- the present invention relates to homogeneous detergent compositions designed especially for laundering fabrics.
- Said compositions are commonly referred to as “heavy-duty liquids” or “HDL's”, since they are designed to remove even the "heaviest” soil loads from fabrics when used in a conventional laundering operation.
- compositions herein comprise fluid carrier medium, a detersive surfactant or mixtures of detersive surfactants, and optionally, detersive enzymes and other conventional detersive ingredients, characterized in that said compositions contain:
- the invention comprises a method for laundering fabrics by agitating said fabrics in a aqueous laundering liquor, said liquor containing at least 0.05 % by weight of a composition of the foregoing type.
- the essential components of the present compositions are the alkyl- or alkenyl-succinate, the citrate builder, and the detersive surfactant.
- the optional detersive adjunct ingredients, as well as the fluid carrier medium, etc., are all well-known to workers in this field.
- Succinate Builder The preferred builders herein are of the general formula R-CH(COOH)CH2(COOH), i.e., derivatives of succinic acid, wherein R is C10-C16 alkyl or alkenyl, preferably C12-C16.
- succinate builders are preferably used in the form of their water-soluble salts, including the sodium, potassium, ammonium and alkanolammonium salts (e.g., mono-, di-, or tri-ethanolammonium).
- succinate builders include: lauryl succinate, myristyl succinate, palmityl succinate, 2-dodecenyl succinate (preferred), 2-tetradecenyl succinate, and the like.
- the citrate builder employed in the practice of this invention includes any water-soluble salt of citric acid.
- Such salts include, for example, sodium, potassium, ammonium or alkanolammonium salts, as in the case of the succinate builders already described.
- the citrate builders are unique in their ability to prevent undue fabric build-up by the succinate builders.
- a highly preferred HDL composition herein comprises a mixture of 3.7 % citrate (specified as citric acid) and 10.4 % 2-dodecenyl succinate as the builder, and is formulated at a pH range of 7.3 to 8.6.
- the detergent compositions of this invention will contain organic surface-active agents ("surfactants") to provide the cleaning benefits associated with the use of such materials.
- HDL which contains an effective amount of detersive surfactant.
- the HDL's it is highly desirable for the HDL's to contain at least 5 % , preferably 7 % to 12 % of an anionic surfactant to give true "heavy-duty" laundering performance on a wide spectrum of soils and stains.
- Anionic detersive surfactants useful herein include the well-known synthetic alkyl benzene sulfonates (which are highly preferred in the present HDL's) alkyl- and alkylether sulfates, paraffin sulfonates, olefin sulfonates, alpha-sulfonates of fatty acids and of fatty acid esters, and the like, which are well-known from the detergency art.
- detersive surfactants contain an alkyl group in the C9-C18 range; the anionic detersive surfactants can be used in the form of their sodium, potassium, ammonium or alkanaolammonium salts.
- Highly preferred HDL compositions comprising anionic detersive surfactants typically contain :
- compositions comprise, besides the mixture of succinate and citrate builders noted, from 7 % to 12 % of the anionic (especially alkyl benzene sulfonate) detersive surfactant and from 10 % to 20 % of the aforesaid ethoxylated alcohol nonionic surfactant.
- compositions with mixed anionic/nonionic surfactants are formulated at pH 7.0 - 9.0, preferably 7.3 - 8.6 Most preferably, the composition contains no more than 16 % of the citrate/succinate builder, as noted above.
- the fuild carrier for the present composition can comprise water; mixtures of water-ethanol; water-glycol mixtures, and the like, all well-known to formulators of HDL's.
- Typically and HDL will comprise 20 % to 40 % fluid carrier, said carrier comprising 80 % water, and 20 % ethanol.
- compositions herein can contain other ingredients which aid in their cleaning performance.
- laundry compositions herein also contain enzymes to enhance their through-the-wash cleaning performance on a variety of soils and stains.
- Amylase and protease enzymes suitable for use in detergents are well-known in the art and in commercially available liquid detergents.
- Commercial detersive enzymes preferably a mixture of amylase and protease are typically used at levels of 0.001 % to 2 %, and higher, in the present compositions.
- compositions herein can contain, in addition to ingredients already mentioned, various other optional ingredients typically used in commercial products to provide aesthetic or additional product performance benefits.
- Typical ingredients include pH regulants, perfumes, dyes, optical brighteners, soil suspending agents, hydrotropes and gel-control agents, freeze-thaw stabilizers, bactericides, preservatives, suds control gents, and the like.
- the compositions are typically used at a concentration of at least 500 ppm, preferably 0.10 % to 2.5 %, in an aqueous laundry bath a pH 7-11 to launder fabrics.
- the laundering can be carried out by agitating fabrics with the present compositions over the range from 5°C to the boil, with excellent results.
- a preferred HDL is as follows:
