Description

Detergent composition.

Technical field

The present invention relates to compositions detergents comprising a branched surfactant in the middle of chain, low levels of a detergency builder system and an alkalinity system comprising carbonate salts. The compositions are solid detergent compositions for washing of clothes.

Background of the invention

Recently a new type has been developed of branched mid chain surfactants. These surfactants are described in unpublished codependent requests WO97 / 38957 (US 97/06485), WO97 / 39090 (US 97/06474), WO97 / 38956 (US 97/06339), WO97 / 39091 (US 97/06476) and WO97 / 38972 (US 97/06338).

The patent JP-A-57-133200 describes dishwashing compositions comprising α-mono (methyl alkyl) ethers branched) glycerol. WO97 / 38956 and WO97 / 39088 describe solid detergent compositions for washing clothes comprising half branched alkyl sulfate surfactant chain, zeolite A and carbonate.

Hard water conditions, due to the presence of Ca and Mg ions in the wash water and tissues,  can reduce the performance of the various components in detergents, especially charged surfactants, such as anionic surfactants. Therefore, in the compositions detergents have traditionally been used reinforcing additives of the detergency to counteract the ions of Ca and Mg, thus softening the water. However, a disadvantage of the presence of high levels of detergency builder additives is that many of these detergency builder additives are not water soluble or only partially water soluble. This can result in a poor solubility of the detergent in  washing water and may cause material deposition detergency builder in washed fabrics and / or in the washing machine or in the dishwasher, which produces for example the gray fabric. In addition, the use of high levels of detergency reinforcing materials can prove very expensive.

Now it has been surprisingly discovered that these specific branched chain-half surfactants they have excellent tensioactivity and cleaning capacity in hard water conditions (very hard). Also, surprisingly it has observed that detergent compositions comprising these branched mid chain surfactants and only a very quantity Small detergent booster additive have a capacity  excellent cleaner. It has also been discovered that branched chain chain surfactants work best in a (slightly) alkaline environment. However, the reduction in detergent compositions, which contain these surfactants branched mid-chain, of the level of reinforcing material of detergency, which are known sources of alkalinity in detergent compositions, produces a less alkaline environment. For make up for this, the inventors have discovered that the introduction in detergent compositions of a small amount of a Alkalinity source, preferably carbonate salts, can supply the alkalinity required for optimal performance of branched mid chain surfactants, while allow to reduce the level of reinforcing materials of the detergency

An additional advantage is that the reduction of levels of detergency builder material in the Detergent compositions reduce the cost of the formulation.

Composition Form

The detergent composition of the invention can be prepared by various methods, including dry mixing and agglomeration of the various compounds included in the detergent composition

The compositions according to the invention they can take various solid physical forms such as those of tablet, scale, tablet and bar and preferably forms granulated

Alternatively, the compositions detergents can be formulated to be compatible with chlorine based bleaches, thus ensuring that the user can add a bleach based on chlorine to the detergent composition at the beginning or during the washing process.

In general, detergent compositions granules according to the present invention can be prepared by different methods, including dry mixing, spray drying, agglomeration and granulation.

The branched surfactant system in the middle of chain of the present invention, preferably with surfactants additional, it is preferably present in the compositions granules in the form of particles of surfactant agglomerate, which preferably do not comprise bleach precursors, and which can take the form of scales, pellets, pips, noodles, tapes, although preferably it takes the form of granules. The most preferred way to process the particles is by agglomerating the powders (eg aluminosilicate, carbonate) with surfactant pastes very active and control particle size of agglomerates resulting within the specified limits. A process of this type involves mixing an effective amount of powder with a surfactant paste with a high content of active substance in one or more agglomerators, such as a tray agglomerator, a Z-shaped blade mixer or more preferably a in-line mixer, such as those manufactured by Schugi (Netherlands) BV, 29 Chroomstraat 8211 AS, Lelystad, The Netherlands, and Gebruder Lödige Maschinenbau GmbH, D-4790 Paderborn 1, Elsenerstrasse 7-9, Postfach 2050, Germany.

The density apparent is measured with a simple funnel and cup device that it consists of a rigidly molded conical funnel on a base and provided with a butterfly valve at its lower end to allow emptying the funnel contents into a glass axially aligned cylindrical and placed under the funnel. He funnel has a height of 130 mm and an internal diameter of 130 mm and 40 mm at its upper and lower ends, respectively. This mounted so that the lower end is 140 mm above the upper surface of the base. The cup has a total height of 90 mm, an internal height of 87 mm and an internal diameter of 84 mm. Its nominal volume is 500 ml.

To perform a measurement, the funnel is filled with hand-poured powder, the butterfly valve is opened and left May the powder overflow the cup. The full cup is separated from the frame and remove excess dust from the cup by passing an edge utensil straight like, p. eg, a knife, by its upper edge. TO then the full cup is weighed and the value is multiplied by two of the weight of powder obtained to obtain the apparent density in g / liter If necessary, the measurements are repeated.
