Description

Washing element of synthetic detergent.

The invention relates to a washing element of synthetic detergent with cleaning and care properties of the skin, based on at least one or more surfactants synthetic as detergent components.

Washing elements of synthetic detergent They have known each other for a long time. Understood here soap-like elements that are used, in most of the cases, for body cleansing or skin cleansing. How detergent substances are used in most cases agents anionic, amphoteric or non-ionic surfactants, depending on the dermatological properties of a detergent wash element essentially also the surfactant used in each case.

At the same time, such synthetic detergent washing elements used instead of the usual tablet soaps must meet numerous requirements that are increasingly severe, especially also in regard to their cleaning power and their care effect. For example, such washing elements must prevent the skin from drying out, must moisturize and especially also have a good compatibility with the skin. On the other hand, these elements must have pleasant washing properties, that is to form enough foam and leave a pleasant sensation on the skin. In addition, the demands placed on the properties of the synthetic detergent washing element itself are increasing. For example, on the one hand the washing element should not tend to crack when it dries, or it should tend to crack only to a very small extent. In this tendency to crack, the water release capacity of the washing element also has a decisive influence. In addition, the washing element must have virtually no tendency to unwanted alterations of the external appearance, such as color changes or a crystallization of components, and must have great long-term stability, even in the presence of moisture. To achieve great long-term stability, microcrystalline waxes and / or paraffin waxes have been used on different occasions, but their compatibility with the skin is
insufficient.

The washing element must also present during the washing process a certain water absorption and dissolution characteristics adapted, so that, in a process of usual wash, water dissolve a sufficient amount of synthetic detergent and it develops its washing effect. Without However, on the other hand, a excessive "blanking" of the washing element, being understood therefore, the property presented by the washing elements of which, in contact with water (for example when deposited in the soap dish), its outer zone passes into a soft, swollen state, which it can no longer be used for cleaning and it is not a wear wanted. The swollen surface layer (stained) can in such case easily removed by hand, or by mechanical means, from non-swollen core of a synthetic detergent element. The optimization of this wear and the characteristics of swelling of the synthetic detergent wash element is of decisively important from a dermatological point of view and economical: if a washing element is too soft and the blinding too large, in each washing operation apply too much surfactant to the skin for cleanliness, which makes dermatological properties worse. To the same time decreases consumer acceptance, because the Washing element is spent too quickly. Yes, on the other hand, the washing element is too hard, it is unpleasant and the Washing element is perceived as too "angular." To the at the same time not enough surfactant dissolves and, in the In most cases, the result is a great tendency to unwanted cracking, because the washing element dries too quickly. In addition, when washing, the consumer finds nasty the hard and rough surface of the elements of washed.

Thus, taken together, an element Optimal synthetic detergent wash must meet a large number of requirements that are partly contradictory to each other.

WO 01/72947 A1 describes soaps of synthetic detergent containing surfactants of sugars, partial glycerides of fatty acids and starch and / or cellulose, which have high stability and consistency and can be produced on an industrial scale, but they don't have a deformability too high or tend to crack when dry

WO 92/13060 describes a composition for washing elements of synthetic detergent that contains alkyl sulfates, monoglycerides, polyethylene glycol and free fatty acids.

Document DE 3011813 describes a procedure to improve the characteristics of use, especially to reduce the release of cleaning products in tablets, presenting the material metal salts of the third and / or fourth group of the periodic table with organic acids and / or inorganic

Document DE 1792029 describes products of synthetic cleaning in tablets composed of alkylbenzenesulfonates, polyethylene glycol ethers of alcohol fatty, sodium alcohol sulfates and a wax component that Contains hard wax, paraffin and beeswax.

US 3766097 describes a composition of synthetic detergent containing beeswax, polypropylene glycol and / or glycerin, a polyoxyethylene polymer and a sodium isethionate ester.

The invention aims to put arrangement a synthetic detergent wash element that solve the above mentioned problems, especially that present enhanced screening characteristics, be it particularly compatible with the skin and be perceived as User friendly during washing.

This objective is achieved through an element of washing of synthetic detergent according to claim 1. Of the dependent claims are perfected advantageous

Thanks to the washing element contains beeswax in combination with one or more fatty acid esters c) and / or at least one or more fatty alcohols d), the ester being fatty acid c) and / or fatty alcohol d) contained or contained in the washing element or synthetic detergent base material in a proportion in percentage by weight greater than beeswax, the washing element has stamping characteristics ostensibly improved and at the same time a very good skin compatibility This is also surprising for the fact that beeswax is often described as disadvantageous when it comes to skin compatibility. On the other hand, the washing element can be practically free of paraffin and / or microcrystalline waxes, thereby improving much more skin compatibility.

As is known, beeswax is a wax with a melting point of 61 to 68 ° C, essentially composed of a mixture of complex wax esters (usually about 65 to 75% by weight, in most cases approximately 70% by weight of beeswax), normal fatty acids and fatty hydroxy acids (usually about 12 to one 15% by weight, in most cases approximately 13 to one 14% by weight), as well as hydrocarbons (usually approximately 5 to 15% by weight, in most cases approximately 10 to 14% by weight). Wax esters can be esters of acids C16 to C36, in particular of acids palmitic and cerotic, being able to present in case given a total of approximately 50 to 70 different esters, or more. The component alcoholic can be a mixture of alcohols C24 to C36 and in Particularly also contain 1- triacontanol. As wax ester of fatty hydroxy acids may be contained primarily Ceryl hydroxypalmitate (if necessary also hydroxystearate of ceryl) (usually about 6 to 11% by weight, in most cases approximately 8 to 9% by weight). The 14-hydroxypalmitin and acids 16-hydroxystearic and 17-hydroxystearic are also almost always components of beeswax. How free wax acids can present in particular lignochloric acid, cerotic acid and acid Melicic It is understood that, as a natural raw material, the wax of bee is subject to variations in its composition and, where appropriate, some of the components may be outside the ranges above mentioned without essentially altering the properties of the beeswax together.

Instead of natural beeswax, or in addition to it, it can also be used in case of wax  of synthetic bee, provided it has a melting point comparable and a comparable composition, especially as defined above, and allows to obtain a washing element of same or comparable characteristics, particularly as regards refers to the skin sensation and its hardness, as well as in Regarding the blinding.

The fatty acid esters used according to the invention may in particular be esters of glycolic fatty acid and / or esters of glyceric fatty acid or esters of alcohols superiors, and alcohol may also present in particular non-esterified hydroxy groups. The fatty acid ester can be in particular a glycol monoester or diester or a monoglyceride or diglyceride, and if necessary also a triglyceride. The ester can be in each case a mixed ester.

The synthetic detergent wash element preferably contains fatty acid esters c) in addition to fatty alcohols d).

Esters of fatty acid c) and fatty alcohol d) are in the washing element or in the base material of the same preferably in a proportion in percentage by weight respectively greater than beeswax. It is enough that only the total content of fatty acid ester c) and fatty alcohol d) be greater than beeswax. Especially preferably, the weight ratio of beeswax is less than that of the ester of fatty acid c).

The proportion by weight of fatty alcohol d) in the washing element or in the base material thereof is preferably less than the fatty acid ester ratio c) in percentage by weight.

Especially when it comes to clogging characteristics in combination with a feeling pleasant washing thanks to a hardness not too large of washing element, it is particularly advantageous that the washing element contain, with respect to the weight of the element of washing or base material:

Bee wax:

0.5 to 6% by weight, preferably 0.5 to 4% by weight, with special preference 1 to 3% by weight and most preferably 1.5 to 2.5% by weight

fatty acid ester c):

2 to 16% by weight, preferably 4 to 12% by weight, especially preferably 6 to 10% by weight and with the greatest preference 6 to 8% by weight

fatty alcohol d):

0.5 to 10% by weight, preferably 1 to 8% by weight, with special preference 2 to 5% by weight and with the greatest preference 3 to 4% by weight

       \ newpage
    

It is understood that the ranges mentioned above for the various components, in particular also the ranges in each case preferred, especially preferred or mostly preferred, may be presented in the composition of the element of wash independently of each other. The content in all three components are preferably preferred in each case, especially preferred or mostly preferred.

The fatty acid ester c) used according to the invention may contain respectively, if necessary exclusively, C14 to C22 fatty acids or also C14 to C24, preferably C14 to C20 fatty acids and especially preferably C16 to C18 fatty acids. Fatty acids are so respectively preferably saturated and can be fatty acids linear or if necessary also branched. The ester can be in in particular an ester of stearic acid, preferably an ester of pure stearic acid. The ester is respectively preferably a glyceride, in particular a monoglyceride or diglyceride, or if necessary also a triglyceride, of acids Fatty mentioned. If necessary, the fatty acid ester may be also a mixed ester. In addition, the detergent wash element synthetic may contain one or several fatty acid esters different. If necessary, the ester may also be an ester of fatty acid of an alcohol more than trivalent.

The at least one fatty alcohol d) may be in in particular a C12 to C22 fatty alcohol, or a C16 a fatty alcohol to C20, or a C16 to C18 fatty alcohol. In particular, fatty alcohol It may include cetyl alcohol and / or stearyl alcohol. The alcohol Fat is preferably saturated. Fatty alcohol can be linear or branched. In particular, fatty alcohol can be cetearyl alcohol (also called cetyl stearyl alcohol), that is a mixture of approximately equal parts of alcohol cetyl and stearyl alcohol. Fatty alcohol d) may include partly also other fatty alcohols, if necessary only above mentioned. If necessary, a part of the fatty alcohol, preferably ≤ 12% by weight, preferably <5 to 10% in weight, can be presented as alkali fatty alcohol sulfate, in particular as sodium fatty alcohol sulfate, and the composition it can also be practically free of alcohol sulfates fatty.

The components beeswax, acid ester fatty c) and fatty alcohol d) can be presented in particular in a joint proportion of 10 to 20% by weight, if necessary 12 to 16% by weight, based on the weight of the washing element or the synthetic detergent base material.

It is especially preferred that the element of wash contains components that form a wax melt homogeneous with a melting point of 50 to 60 ° C, or therefore that the Washing element contains a homogeneous wax. A homogeneous wax of this type occurs especially at room temperature and is long term stable. It has been proven that a melt of This type fits especially well to the requirements of a washing element of synthetic detergent and is not only perceived as pleasantly "soft" by the user during washing, but at the same time it also surprisingly presents a very good dissolution behavior and characteristics of particularly favorable conceitment. In particular, the wax which constitutes the melt can also be homogeneous to room temperature. It is assumed that with homogeneous wax is achieved that the composition absorbs less water or absorbs it with less speed, thus improving the characteristics of blinding. So therefore, the homogeneous wax also influences the characteristics of swelling of the washing element together. Instead, it seems that, for example in the case of microceres, the absorption of water and swelling characteristics in the structure microcrystalline are less favorable, since for example water it can spread more easily between interfaces or crystallite surfaces.

As components that form a melt of homogeneous wax can be provided in particular beeswax, fatty acid esters c) and fatty alcohols d), for which the above applies.

The presence of such wax melts homogeneous is also particularly advantageous, because it allows dispense mostly or completely with the presence of paraffins or paraffin waxes and / or microcrystalline waxes in the composition. This significantly improves compatibility with the skin. For some application cases it may be acceptable that the washing element contains ≤ 2 to 5% by weight of paraffin and / or? 2 to 5% by weight of microcrystalline waxes, or that the total content of paraffin and microcrystalline waxes be? 2 a 5% by weight, based on the weight of the washing element or material synthetic detergent base. Microcrystalline waxes are in this case paraffin waxes with a melting point between 60 and 90 ° C, in which isoparaffin and substituted aromatics predominate with naphthene and that are finely crystalline at temperature ambient.

Although compositions with melts of homogeneous wax with a melting point of 50 to 60 ° C have given especially good results, in certain compositions you can happen that some of the components of the wax melt They are separated by crystallization. This can produce a roughness not desired of the washing elements, being able to the components Crystallized recognize sometimes even with the naked eye. For the so, for certain compositions it has proven to be particularly advantageous to add crystallization inhibitors that inhibit a crystallization of wax melt components homogeneous Surprisingly it has been proven that with the presence of such crystallization inhibitors it is also possible to improve ostensibly the characteristic characteristics of the element washing Surprisingly, the screening characteristics improve significantly before it is possible to perceive a crystallization with the naked eye. This may be attributable to that with Crystallization inhibitors are already preventing the formation of seed crystals or microcrystals and thus are improved ostensibly the swelling characteristics of the element of Washing at the microscopic level and also together.

As crystallization inhibitors have resulted especially suitable are inulin and / or alcohol glutamates alkali metal fatty, particularly those with a fatty alcohol C8 to C22 or C8 to C30, especially preferably a C10 fatty alcohol to C16 or C12 to C14 and most preferably a fatty alcohol of coconut oil, which can occur particularly in combination. The alkali metal salts can be so in particular sodium salts, if necessary also salts Potassium If necessary, they can also be used instead of inulin, other polysaccharides that present d-fructose or other bound polysaccharides mainly or exclusively beta (1,2) -glycoside, even when inulin It is especially preferable. Surprisingly, inulin and / or alkali metal fatty alcohol glutamates, especially the sodium cocoyl glutamate, effectively reduce the crystallization separation of components of the composition mentioned, which contains waxes that melt homogeneously in the temperature range of 50ºC to 60ºC, which at the same time confers very nice washing characteristics. Glutamates  alkali metal fatty alcohol can be respectively esterified in the carboxyl group of the C1 atom or of the C4 atom. To the same time surprisingly features of washing element particularly favorable. It is preferable that beeswax is always a component of these waxes

It is advantageous that the inulin is contained in a proportion of 0.1 to 10% by weight, preferably a 0.2 to 5% by weight, based on the total weight of the washing element or of the synthetic detergent base material. The content in inulin can in particular also be 0.2 to 2% by weight and especially preferably from 0.5 to 2% by weight.

The fatty alcohol glutamate content of alkali metal may be from 0.1 to 5% by weight, preferably 0.5 to 4% by weight or 1 to 3% by weight, based on weight total of the washing element or detergent base material synthetic.

If necessary, the composition may contain, at less in part instead of metal fatty alcohol glutamate alkaline, or in addition thereto, a fatty alcohol glutamate of ethoxylated alkali metal. The glutamate weight ratio of ethoxylated fatty alcohol is preferably ≤ 50% by weight or ≤ 10 to 20% by weight of that of non-ethoxylated glutamates, or not they are present.
