Description

The non-aqueous liquid detergent compositions that contains the medium chain branched chain surfactant

Invention field

The present invention relates to the liquid laundry detergent product, it is being non-water in nature, it is the stable dispersions form of particulate matter, and it comprises that medium chain branched chain surfactant and it preferably also comprise other material, for example SYNTHETIC OPTICAL WHITNER and/or conventional detergent composition auxiliary agent.

Background of invention

Detergent product is considered to be more convenient for using than dry powder or granulated detergent product usually, and therefore, liquid washing agent is found and obviously helps the human consumer.This detergent product is easy to measure, be dissolved in fast washing water, can be applied to zone dirty on the clothes that is washed and non-dusting easily as concentrated solution or dispersion liquid.Usually they also account for less storage space than granular product.In addition, liquid washing agent can add the formula materials that can not stand drying operation and can not degenerate, and drying operation is generally used for preparing particulate or granulated detergent product.

Although liquid washing agent has many advantages that are better than granular detergent products, obviously also have some shortcomings.Especially, detergent composition component compatible in particulate product can interact in liquid or react to each other, especially in liquid, aqueous environment.Therefore, these components, for example enzyme, tensio-active agent, spices, whitening agent, solvent and especially SYNTHETIC OPTICAL WHITNER and bleach activator especially are difficult to add in the detergent product with acceptable chemical stability.

A kind of trial of the chemical compatibility of raising detergent composition component in detergent product is preparation non-water (or anhydrous) liquid detergent composition.In these non-fishery products, the component of some common solid detergent composition has the undissolved tendency of maintenance in liquid product at least, therefore compares their less each other reactions with its situation about being dissolved in the fluid matrix.Contain active substance, for example the non-aqueous liquid detergent compositions of peroxygen bleach is disclosed in the US4615280 of the Hepworth etc. of promulgation on October 17th, 1986 for example; The US4929 380 of the Schultz of promulgation on May 29 nineteen ninety etc.; The US5008031 of the Schultz of promulgation on April 16th, 1991 etc.; June in 1981 disclosed Elder on the 10th etc. EP-A-030096; June in 1992 disclosed Hall on the 11st etc. WO 92/09678 and October in 1993 disclosed Sanderson on the 13rd etc. EP-A-565017.

Although can improve the chemical compatibility of component in non-aqueous liquid detergent compositions, the physical stability of said composition can become a problem.This is owing to be separated in this product suspension as dispersive undissolved solid particulate matter and descend and be deposited on the container bottom that detergent product is housed.As the result of this class problem, also be difficult in the non-aqueous liquid detergent product, add the enough suitable types and the surfactant materials of quantity.Therefore, must select surfactant materials, thereby make them be suitable for providing acceptable fabric washing performance, but use this material must not can to cause the unacceptable degree that is separated of composition to composition.Can add phase stabilizer in this product, for example thickening material or viscosity control agent are to improve its physical stability.Yet these materials can increase the cost and the volume of product, and the laundry/scourability of this detergent composition is not had help.

Can also select to be used for the surfactant system of this liquid laundry detergent product, in fact it can influence the liquid phase structure of product, thereby promote to be dispersed in the suspension of particulate constituent in this structurizing liquid phase.Example with product of structured surfactant system is the US 5389284 of the van der Hoeven of February 14 nineteen ninety-five promulgation etc., and it adopts based on the alcohol alkoxylate nonionogenic tenside of relative high density and the structured surfactant system of negatively charged ion defloculating agent.In adopting the product of structured surfactant system, structurized liquid phase must be enough viscosity, with the sedimentation of the particulate constituent avoiding suspending be separated, thereby but can not too stickingly influence the pourability and the dispersiveness of Betengent product unfriendly.

As mentioned above, obviously people need to find always and provide the liquid of on-aqueous liquid product form to contain particulate detergent compositions, it has high-caliber chemical substance, the stability of SYNTHETIC OPTICAL WHITNER and enzyme for example, thus commercial acceptable phase stability, pourability and detergent composition laundry, cleaning or bleachability are arranged.Therefore, the purpose of this invention is to provide the method that the non-water of preparation contains the particle liquid Betengent product, it has chemistry and physical stability and outstanding pourability and the fabric laundry/bleaching characteristic that especially needs.

As mentioned above, people also constantly need preparation on-aqueous liquid product, and it provides accepting and desirable balance between scourability and the product stability.Therefore the purpose of this invention is to provide non-aqueous liquid detergent compositions, it is especially stable and effective in the hard water environment.

Have been found that medium chain branched chain surfactant of the present invention provides the low-temperature stability of the improvement of the finished product, less bottom product and the product of improvement and the mixing rate of water in bottle.

Have been found that the surfactant system that contains as some selection of the medium chain branched chain surfactant of giving a definition and other auxiliary agent provides the non-aqueous liquid detergent compositions of realizing above-mentioned purpose.The key element of the combination of components of these selections is described below.
