Description

liquid soaps

Field of the Invention

The invention relates to new liquid soap formulations which contain selected sugar surfactants, fatty acid partial glycerides and fatty acids and other co-surfactants as essential components, and to their use in liquid soap preparations.

State of the art

The large number of liquid soaps that are offered to consumers nevertheless make it clear that there is a constant need among consumers for further improved products, which, in particular due to improved stabilities, also have good dermatological compatibility, increased foaming power, higher creaminess, rinsing power and skin feel or Mark regreasing. In contrast, soap manufacturers are looking for soap-containing formulations which, in addition to unchanged stability, also have constant viscosities and, moreover, allow the easy incorporation of substances sensitive to hydrolysis.

The complex object of the present invention was therefore to provide liquid soaps with the complex requirement profile described.

Description of the invention

The invention relates to liquid soaps containing

(a) 0.1 to 20% by weight of sugar surfactants selected from the group formed by (a1) alkyl and / or alkenyl oligoglycosides and / or (a2) fatty acid N-alkyl polyhydroxyalkylamides,

(b) 0.1 to 20% by weight of fatty acid partial glycerides,

(c) 0.5 to 34% by weight of anionic, nonionic and / or amphoteric co-surfactants,

(d) 0.5 to 30% by weight of fatty acids and with the proviso that the amounts given with water and possibly other auxiliary substances and additives are 100% by weight.

Another object of the invention is the use of these agents in liquid soap preparations.

Surprisingly, it has been found that liquid soaps can be produced from selected sugar surfactants, partial glycerides, fatty acids and other co-surfactants, partial glycerides, which are stable over a longer storage period. It is particularly surprising that there is no immediate hydrolysis of the partial glyceride, for example glycerol monooleate, at the alkaline pH or that the hydrolysis has no influence on the stability and viscosity of the liquid soap formulations. The stable and creamy foam as well as the regreasing or the skin feeling is also advantageous.

Alkyl and / or alkenyl oligoglycosides

Alkyl and alkenyl oligoglycosides which make up the sugar surfactant component (a1) are known nonionic surfactants which follow the formula (I)

R ¹ 0- [G] _p (I)

in which R ^{1 is} an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p is a number from 1 to 10. They can be obtained according to the relevant procedures in preparative organic chemistry. Representative of the extensive literature here is the review by Biermann et al. in Starch /force 45, 281 (1993), B.Salka in Cosm.Toil. 108, 89 (1993) and J.Kahre et al. in SÖFW-Journal Issue 8, 598 (1995).

The alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (I) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p must always be an integer in a given compound and especially here can assume the values p = 1 to 6, the value p for a certain alkyl oligoglycoside is an analytically determined arithmetic parameter, which usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, such alkyl and / or alkenyl oli- goglycosides are preferred, the degree of oligomation of which is less than 1.7 and in particular between 1.2 and 1.4. The alkyl or alkenyl radical R ¹ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronalcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis. Alkyl oligoglucosides of the chain length Cβ-Cio (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical Cβ-Ciβ-coconut fatty alcohol by distillation and can be contaminated with a proportion of less than 6% by weight of Ci2-alcohol and Alkyl oligoglucosides based on technical Cg / n oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R ¹ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, as described above, which can be obtained as described above. Alkyl oligoglucosides based on hydrogenated Ci2 / i4 coconut alcohol with a DP of 1 to 3 are preferred.

The preparations according to the invention can contain the alkyl and / or alkenyl oligoglycosides in amounts of 0.1 to 20, preferably 0.5 to 10 and in particular 1 to 5% by weight, based on the total composition.

Fatty acid-N-alkylpolyhvdroxyalkylamide

Fatty acid N-alkylpolyhydroxyalkylamides which make up sugar surfactant component (a2) are nonionic surfactants which follow the formula (II),

I

R ² CO-N- [Z] (II)

in the R ² CO for an aliphatic acyl radical with 6 to 22 carbon atoms, R ³ for an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands. The fatty acid N-alkyl polyhydroxyalkylamides are known substances which can usually be obtained by reductive amination of a reducing sugar with an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride. With regard to the processes for their production, reference is made to US Pat. Nos. 1,985,424, 2,016,962 and 2,703,798 and international patent application WO 92/06984. An overview of this topic by H. Kelkenberg can be found in Tens.Surf.Deterg. 25, 8 (1988).

The fatty acid N-alkylpolyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose. The preferred fatty acid N-alkylpolyhydroxyalkylamides are therefore fatty acid N-alkylglucamides as represented by the formula (III):

R2CO-N-CH ₂ .CH-CH-CH-CH-CH ₂ OH (III)

I OH

The fatty acid N-alkylpolyhydroxyalkylamides used are preferably glucamides of the formula (III) in which R ^{3 is} an alkyl group and R ² CO is the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmoleic acid, stearic acid, isostearic acid, Oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, arachic acid, gadoleic acid, behenic acid or erucic acid or their technical mixtures. Fatty acid N-alkylglucamides of the formula (III) which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or Ci∑ coconut fatty acid or a corresponding derivative are particularly preferred. Furthermore, the polyhydroxyalkylamides can also be derived from maltose and palatinose.

The use of the fatty acid N-alkylpolyhydroxyalkylamides is also the subject of a large number of publications. Their use as a thickener is known, for example, from European patent application EP 0285768 A1 (Hüls). French published patent application FR 1580491 A (Henkel) describes aqueous detergent mixtures based on sulfates and / or sulfonates, nonionic surfactants and, if appropriate, soaps, which contain fatty acid N-alkylglucamides as foam regulators. Mixtures of short- and longer-chain glucamides are described in German patent DE 4400632 C1 (Henkel). The German Offenlegungsschriften DE 4326959 A1 and DE 4309567 A1 (Henkel) also report on the use of glucamides with longer alkyl residues than pseudoceramides in skin care products and on combinations of glucamides with protein hydrolysates and cationic surfactants in hair care products. International patent applications WO 92/06153, WO 92/06156, WO 92/06157, WO 92/06158, WO 92/06159 and WO 92/06160 (Procter & Gamble) relate to mixtures of fatty acid N-alkylglucamides with anionic surfactants, Surfactants with a sulfate and / or sulfonate structure, ether carboxylic acids, ether sulfates, methyl ester sulfonates and nonionic surfactants. The use of these substances in a wide variety of washing, rinsing and cleaning agents is described in international patent applications WO 92/06152, WO 92/06154, WO 92/06155, WO 92/06161, WO 92/06162, WO 92/06164, WO 92 / 06170, WHERE 92/06171 and WO 92/06172 (Procter & Gamble).

The surfactants mentioned are exclusively known compounds. With regard to the structure and manufacture of these substances, reference is made to relevant reviews, for example, J.Falbe (ed.), "Surfactants in Consumer Products", Springer Verlag, Berlin, 1987, pp. 54-124 or J.Falbe (ed.), "Catalysts, Tenside und Mineralöladditive ", Thieme Verlag, Stuttgart, 1978, pp. 123-217.

Monoglyceride (ether) sulfates

Monoglyceride sulfates and monoglyceride ether sulfates are known substances which can be obtained by the relevant methods of preparative organic chemistry. Usually goes to prepare them from triglycerides which, if appropriate, are transesterified to the monoglycerides after ethoxylation and subsequently sulfated and neutralized. It is also possible to react the partial glycerides with suitable sulfating agents, preferably gaseous sulfur trioxide or chlorosulfonic acid [cf. EP 0561825 B1, EP 0561999 B1 (Henkel)]. If desired, the neutralized substances can be subjected to ultrafiltration in order to reduce the electrolyte content to a desired level [DE 4204700 A1 (Henkel)]. Overviews of the chemistry of the monoglyceride sulfates are, for example, by AK Biswas et al. in J.Am.Oil.Chem.Soc. 37, 171 (1960) and FU Ahmed J.Am.Oil.Chem. Soc. 67, 8 (1990). The monoglyceride (ether) sulfates to be used in accordance with the invention follow the formula (V),

The starting materials are preferably condensed with halocarboxylic acids or their salts, in particular with sodium chloroacetate, one mol of salt being formed per mole of betaine. The addition of unsaturated carboxylic acids, such as acrylic acid, is also possible. Regarding the nomenclature and in particular the distinction between betaines and "real" amphoteric surfactants, reference is made to the contribution by U. Ploog in Seifen-Öle-Fette-Wwachs, 198, 373 (1982). Further overviews on this topic can be found, for example, by A. O'Lennick et al. in HAPPI, Nov. 70 (1986), S. Holzman et al. in Tens.Surf. Det. 23: 309 (1986), R. Bilbo et al. in Soap Cosm. Chem. Spec, Apr. 46 (1990) and P. Ellis et al. in Euro cosm. 1, 14 (1994). Examples of suitable betaines are the carboxyalkylation products of secondary and in particular tertiary amines which follow the formula (VI)

fatty acid polyglycol ester

Fatty acid polyglycol ester sulfates preferably follow the formula (VIII), R ¹² COO (AO) _w S0 ₃ X (VIII)

in which R ¹² CO stands for a linear or branched, saturated or unsaturated acyl radical having 6 to 22 carbon atoms, w for numbers of 1 to 3 on average and AO for a CH2CH2O-, CH ₂ CH (CH ₃ ) 0- and / or CH ( CH ₃ ) CH ₂ 0 radical and X represents an alkali and / or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium, are known anionic surfactants and are prepared by sulfation of the corresponding fatty acid polyglycol ester. These in turn can be obtained using the relevant preparative processes in organic chemistry. For this purpose, ethylene oxide, propylene oxide or a mixture thereof - in random or block distribution - is added to the corresponding fatty acids, this reaction being acid-catalyzed, but preferably in the presence of bases, such as, for example, sodium methylate or calcined hydrotalcite. If a degree of alkoxylation of 1 is desired, the intermediates can also be prepared by esterifying the fatty acids with an appropriate alkylene glycol. The sulfation of the fatty acid polyglycol esters can be carried out in a manner known per se with chlorosulfonic acid or preferably gaseous sulfur trioxide, the molar ratio between fatty acid polyglycol ester and sulfating agent being in the range from 1: 0.95 to 1: 1, 2, preferably 1: 1 to 1: 1 , 1 and the reaction temperature can be 30 to 80 and preferably 50 to 60 ° C. It is also possible to undersulfate the fatty acid polyglycol esters, ie to use significantly fewer sulfating agents than would be stoichiometrically required for complete conversion. If, for example, one chooses molar amounts of fatty acid polyglycol ester to sulfating agent from 1: 0.5 to 1: 0.95, mixtures of fatty acid polyglycol ester sulfates and fatty acid polyglycol esters are obtained, which are also advantageous for a whole range of applications. In order to avoid hydrolysis, it is very important to carry out the neutralization at a pH in the range from 5 to 9, preferably 7 to 8. Typical examples of suitable starting materials are the addition products of 1 to 3 mol of ethylene oxide and / or propylene oxide, but preferably the adducts with 1 mol of ethylene oxide or 1 mol of propylene oxide with caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, Palmoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid and their technical mixtures, which are then sulfated and neutralized as described above. Fatty acid polyglycol ester sulfates of the formula (VIII) are preferably used in which R ¹² CO stands for an acyl radical having 12 to 18 carbon atoms, x for an average of 1 or 2, AO for a CH∑C ^ O group and X for sodium or ammonium, such as for example lauric acid + 1 EO sulfate sodium salt, lauric acid + 1 EO sulfate ammonium salt, coconut fatty acid + 1 E0 sulfate sodium salt, coconut fatty acid + 1 EO sulfate ammonium salt, tallow fatty acid + 1 EO sulfate sodium salt, tallow fatty acid + 1 EO sulfate ammonium salt and mixtures thereof.

wherein R ¹⁴ and R ¹³ independently of one another represent H or alkyl radicals having 1 to 20 carbon atoms, with the proviso that R ⁴ and R ¹³ together have at least 6 and preferably 10 to 16 carbon atoms. Regarding production and use, see the review article J.Am.Oil. Soc. 55, 70 (1978).

Internal olefin sulfonates, but preferably α-olefin sulfonates, can be used which result when R ¹⁴ or R ^{13 are} hydrogen. Typical examples of olefin sulfonates used are the sulfonation products which are obtained by treating SO ₃ with 1-, 2-butene, 1-, 2-, 3-hexene, 1-, 2-, 3-, 4-octene, 1- , 2-, 3-, 4-, 5-decene, 1-, 2-, 3-, 4-, 5-, 6- dodecene, 1-, 2-, 3-, 4-, 5-, 6- , 7-tetradecene, 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-hexadecene, 1-, 2-, 3-, 4-, 5-, 6-, 7- , 8-, 9-octadecene, 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-eicosen and 1-, 2-, 3-, 4- , 5-, 6-, 7-, 8-, 9-, 10- and 11-docosen. After sulfonation has taken place, neutralization is carried out, after which the olefin sulfonate is present in the mixture as an alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium, glucammonium, preferably sodium salt. Both olefin sulfonates in aqueous paste, preferably at a pH of 7 to 10, and also as anhydrous products, preferably as granules, can be used, as can be obtained by conventional spray drying, drying in a thin layer ("flash dryer") DE 19710152 C1 (Henkel) or in a fluidized bed dryer ("sket system").

Alkoxylated carboxylic acid esters

Alkoxylated carboxylic acid esters are known from the prior art. For example, such alkoxylated carboxylic acid esters can be obtained by reacting alkoxylated carboxylic acids with alcohols. For the purposes of the present invention, however, the compounds are preferably prepared by reacting carboxylic acid esters with alkylene oxides using catalysts, in particular using calcined hydrotalcite according to German Offenlegungsschrift DE 3914131 A, which provide compounds with a restricted homolog distribution. Both carboxylic acid esters of monohydric alcohols and polyhydric alcohols can be alkoxylated by this process. According to the present invention, preference is given to using alkoxylated carboxylic acid esters of the formula (X)

Alkoxylated carboxylic acid esters of the formula (X) are particularly suitable, in which R ¹⁵ CO is a linear or branched, saturated or unsaturated acyl radical having 6 to 22 and in particular 10 to 18 carbon atoms, AlkO for ethylene oxide and / or propylene oxide, n on average for numbers 5 to 20 and R ^{16 is} an aliphatic alkyl radical having 1 to 8, preferably 1 to 4 carbon atoms and in particular methyl. Preferred acyl radicals are derived from carboxylic acids having 6 to 22 carbon atoms of natural or synthetic origin, in particular from linear, saturated and / or unsaturated fatty acids, including technical mixtures thereof, as are obtainable by fat cleavage from animal and / or vegetable fats and oils, for example from coconut oil, palm kernel oil, palm oil, soybean oil, sunflower oil, turnip oil, cottonseed oil, fish oil, beef tallow and lard. Examples of such carboxylic acids are caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, gadoleic acid, behenic acid and / or erucic acid ,

Examples of such compounds are methyl lauric acid, methyl coconut fatty acid and methyl tallow fatty acid alkoxylated with an average of 5, 7, 9 or 11 moles of ethylene oxide.

The liquid soaps according to the invention can contain the surfactants in amounts of 0.5 to 34, preferably 1 to 30 and in particular 5 to 25% by weight, based on the overall composition.

Examples

Liquid soap preparations were prepared (Examples 1 to 3 are according to the invention, V1 is used for comparison) and their foaming behavior and storage stability with (-) = poor, (+) = satisfactory, (++) = good to (+++) = very well rated. The Brookfield viscosity (20 ° C., 10 rpm, spindle 5, mPas) was also measured. The results are summarized in Table 1.

Table 1: Liquid soaps - compositions and properties (quantities as% by weight)

The stability of formulations 1 and V1 was determined on the basis of the pH value, the acid, saponification and peroxide number over a period of 3 months. The results are summarized in Table 2. The increase in the acid number from 1.1 to 1.6 at 40 ° C. for formulation 1 can only be seen as a slight trend.
