Description

[Detailed description of the invention] Note The present invention provides a lamellar droplet structure containing a sufficient amount of detergent-active substance and dispersed in a continuous aqueous phase. In an aqueous liquid detergent composition optionally also containing electrolytes sufficiently dissolved to obtain a related. In particular, the present invention relates to detergent compositions with a lamellar structure containing relatively low levels of water. do.

Lamellar droplets have been described in various literature (e.g. H9^, Barnes.

"Detergents", Ch, 2. and K., 11alters (eds.) 　Rheometry　:Industrial Applications” , J Jiley & 5ons, Letchworth 1980) among others. It is a special type of surfactant structure known for.

Such lamellar suspensions may, for example, have the fluidity and/or turbidity that consumers prefer. It is used to give characteristics such as appearance. Much of this is done by detergent builders, e.g. Particulate solids such as grains or abrasive particles may also be suspended. This type does not contain suspended solids. Examples of such liquids are described in US Pat. No. 4,244,840. solid grain Examples of suspended children are European Patent Application Publications No. 1.60342 and European Patent Application No. 38101. No. 104,452 and the above-mentioned U.S. Pat. No. 4,244,840. has been done.

Other examples are described in European Patent Application No. 151,884, where The lamellar droplets are called r-spherulites J.

The presence of lamellar droplets in liquid detergent products can be determined by methods known to those skilled in the art, such as optical methods. method, various rheometry devices, X-ray or neutron scattering and electron microscopy). obtain.

The droplet consists of an onion-like morphology of two concentric layers of surfactant molecules, with water between them. or trapped in an electrolyte solution (aqueous phase). These droplets are tightly packed The system has a very good balance between physical stability and solid-suspension properties and useful fluidity. One preferred combination is obtained.

The viscosity and stability of the product depends on the volume fraction of the liquid occupied by the droplets. one Generally, the droplets are just touching (space-filling) when the volume fraction is about 0.6. ) state.

Under these conditions, an acceptable viscosity (i.e., at a shear rate of 21 s'') 2.5 Pas or less, preferably I Pas or less). It will be done. This volume fraction also provides useful solid-suspension properties.

A problem in formulating liquid detergent compositions is to prevent the occurrence of agglomeration. given When aggregation occurs between lamellar droplets at a certain volume fraction, a network structure is formed throughout the liquid. Therefore, the viscosity of the corresponding product increases. Agglomeration affects the phase separation of the product It also causes instability.

The applicant's blur (early) unpublished European patent application No. 89201530.6 ( EP 346995) discloses that in order to increase stability and/or reduce viscosity, a hydrophilic backbone and one or more hydrophobic side-groups ) can be incorporated into an aqueous liquid detergent composition having a lamellar structure. Are listed.

In the above patent application The compositions described contain relatively high levels of water, i.e., about 371 or more. Ru.

Peptizing polymers are used in aqueous liquid detergent compositions with a lamellar structure containing relatively low levels of water. It has been newly discovered that it can be used for stabilization and/or viscosity reduction.

The present invention therefore provides a solution comprising a suspension of lamellar droplets of a detergent active substance in an aqueous continuous phase. Detergent compositions comprising a peptizing polymer and 1 to 35 parts by weight of water Ru.

The industry uses liquid detergent compositions that contain no water or low levels of water. However, since these compositions are not usually in the form of lamellar droplets, Advantages such as those that can be found in detergent compositions with a lamellar structure (e.g. solid suspension) characteristics, robustness) and tolerance to electrolyte levels) does not have These conventional compositions often have acceptable viscosities and/or It also has no physical stability.

The concentration of the liquid detergent composition in the washing liquid is preferably 0.1 to 10 weight 2 -0, 1 to 3 weight 2 is more preferred.

The invention is further illustrated by the following examples.

(Margin below) XL”LL Polymer 1 A preferred method of making peptized polymers is to make an r-stem j polymer and then combine it with Consists of reaction with one or more side groups.

Polymers containing a hydrophilic backbone and one or more hydrophobic side groups (e.g., applicants' co-produced polymers) (described in co-pending European Patent Application No. 89201530.6) is a hydrophilic and one or more hydrophobic moieties. non-ion Polymers containing ionic monomers and ionic monomers (e.g. (described in British Patent Application No. 8924478.4) describes the use of non-ionic r1#j ports. It may be prepared by the present method of reacting a remer with one or more ionic groups.

An example of a suitable reaction between a backbone polymer and a side group is an acid group on the backbone polymer or An esterification reaction that esterifies a hydroxy group with a side hydroxy group or an acid group. One example is response.

If the backbone polymer is hydrophilic, two cases can be distinguished. First, the trunk polymer is , hydrophobic moieties (e.g. fatty alcohols, fatty glycerol ethers, fatty acids Droxyalcohol, alkoxylated fatty alcohol and alkyl polyglycosylation may contain a carboxylic acid group that can be esterified with In this case, the stem polymer is , preferably contains no carboxylic anhydride groups, or the backbone polymer is preferably free of carboxylic acid anhydride groups, e.g. For example, hydrophilic moieties containing groups such as fatty acids and fatty ether carboxylates It may also contain an alcohol group that can be stellated.

Preferably, at least 501 of the backbone monomer consists of a reactive group that can be esterified. More preferably, 751 or more of the monomers contain a reactive group, and 901 or more of the monomers contain a reactive group. is most preferred.

The reason for this is that the esterification reaction is an equilibrium reaction, and under normal conditions a small amount (i.e., the main This is because approximately 0.2 to 101) of the reactive groups in the ester are not esterified. Polymer If the "r-stem" contains a relatively large amount of reactive groups, it is possible to provide a peptized polymer. relatively small amounts of these side groups are sufficient. The preferred environment for the esterification reaction is The backbone polymer has a high concentration, the side group moieties have a relatively high concentration and a relatively low pm.

A particularly preferred R type of this polymer production method includes a backbone polymer and a surface-active property. reaction with hydrophobic or ionic moieties. An example of such a reaction is Esters of a trunk containing a bonic acid group and an alkoxylated non-ionic surfactant It is. The use of surfactants as a source for side groups in polymers is due to this. 1n-situ production of peptized polymers is possible, and polymers are oxidized under acid conditions. Can be formed in the presence of excess surfactant; reactivity that does not react with the trunk in an equilibrium reaction surfactants may be present as detergent actives in the final detergent composition; Conveniently, this method avoids wastage of starting material and can be used at the final stage of product formulation. It is also possible to produce polymers of Glue polymers are used in compositions that contain all or a significant amount of the ingredients of the final detergent composition. It can be manufactured "in 5 itu".

The production of this polymer allows for relatively low a low pH, i.e. less than 6.0, more preferably less than 4.0, most preferably less than 2.0. The lower pH, preferably carried out at higher This is conveniently achieved by having the compound present in non-neutralized form.

In this reaction, an anionic surfactant such as an appropriate amount of NaOH and/or KOH is added. It can be neutralized and stopped by adding.
