[0001] COSMETIC COMPOSITIONS COMPRISING GLYCEROL ESTERALKOXYLATES AND SURFACTANTSThe present invention relates to a cosmetic composition comprising (A) a mixture ofglycerol ester alkoxylates and (B) one or more surfactants, as well as to the use ofthe mixture of glycerol ester alkoxylates as a rheology modifier or thickener in acosmetic composition.Cosmetic compositions typically contain surfactants and a thickener. However,certain surfactants are not compatible with certain thickeners. For example, certainsurfactants, in particular certain ionic surfactants, may decrease the stability and thus the storability of thickened cosmetic compositions. In general, there is a need for cosmetic compositions that are stable and storable. In particular, there is a need for cosmetic compositions that contain a thickenerwhich is compatible with various surfactants, including ionic surfactants.Surprisingly, it has been found that certain glycerol ester alkoxylates can effectively thicken cosmetic compositions that contain various surfactants.Accordingly, the present invention relates to a cosmetic composition comprising(A) a mixture of glycerol ester alkoxylates selected from the substances of thefollowing formula (I) wherein R1, R2and R3are, independent from each other, selected from linear or branched alkylene groups (CmH2m) with m being 2 or 3 or mixtures thereof; x, y and z are, independent from each other, integer numbers from 0 to 300, where at least one of the variables x, y and z is 1 or an integer number greater than 1, preferably are, independent from each other, integer numbers from 1 to 250, more preferably from 2 to 200, even more preferably from 5 to 150, particularly preferably from 10 to 120, extraordinarily preferably from 15 to 110 and especially preferably from 20 to 100; R4, R5and R6are, independent from each other, selected from hydrogen, linear or branched, preferably linear, saturated or unsaturated acyl groups comprising from 8 to 30 carbon atoms or mixtures thereof, preferably are, independent from each other, selected from hydrogen, linear or branched, preferably linear, saturated or unsaturated acyl groups comprising from 12 to 30 carbon atoms or mixtures thereof, more preferably are, independent from each other, selected from hydrogen, linear or branched, preferably linear, saturated or unsaturated acyl groups comprising from 12 to 24 carbon atoms or mixtures thereof, even more preferably are, independent from each other, selected from hydrogen, linear or branched, preferably linear, saturated or unsaturated acyl groups comprising from 12 to 20 carbon atoms or mixtures thereof, and particularly preferably are, independent from each other, selected from hydrogen, linear or branched, preferably linear, saturated or unsaturated acyl groupscomprising from 14 to 20 carbon atoms or mixtures thereof, andwherein in the definitions of R4, R5and R6above, at least one of R4, R5and R6has a meaning different from hydrogen (acyl group); characterized in thatx+y+z is, based on a molar average, a number from 50 to 300,preferably from 60 to 300, more preferably from 70 to 280, even more preferably from 85 to 250 and particularly preferably from 90 to 250; at least 70 mol%, preferably at least 75 mol%, more preferably at least 80 mol% and even more preferably at least 85 mol% of the glycerol ester alkoxylates of the formula (I) in the mixture, in each case based on the total amount of the glycerol ester alkoxylates of the formula (I) in the mixture, are glycerol ester alkoxylates of the formula (I), wherein all of the groups R4, R5and R6have a meaning different from hydrogen (acyl groups); and at least 30 mol%, preferably at least 40 mol%, more preferably at least 50 mol%, even more preferably at least 60 mol% and particularly preferably at least 70 mol% of those groups R4, R5and R6, which have a meaning different from hydrogen (acyl groups), are linear or branched, preferably linear, saturated or unsaturated acyl groups comprising 16 to 20 carbon atoms or mixtures thereof and preferably are linear or branched, preferably linear, saturated or unsaturated acyl groups comprising 16 to 18 carbon atoms or mixtures thereof, in each case based on the total amount of the linear or branched, preferably linear, saturated or unsaturated acyl groups R4, R5and R6; and(B) one or more surfactants.Advantageously, the cosmetic compositions of the present invention are stable and storable.The cosmetic composition of the invention comprises (A) a mixture of glycerol esteralkoxylates selected from the substances of the formula (I).In the mixtures of glycerol ester alkoxylates of the formula (I), those of the groups R4, R5and R6, which have a meaning different from hydrogen, are referred to as “acyl groups”.

It is also particularly advantageous to prepare the alkaline earth metal catalyst (MC) by first dispersing the alkaline earth metal compound (MA) in a polyalkylene glycol having a molecular weight from 100 g / mol to 1500 g / mol or mixtures of such polyalkylene glycols, or in a C1-C18alkyl-capped polyalkylene glycol having a molecular weight from 100 g / mol to 1500 g / mol, preferably a methyl-capped polyalkylene glycol having a molecular weight from 100 g / mol to 1500 g / mol and more preferably a methyl-capped polyethylene glycol having a molecular weight from 100 g / mol to 1500 g / mol or mixtures of such alkyl-capped polyalkylene glycols, optionally in the presence of water, after which the reaction mixture is further treated with the acid (AC). The dispersing step may be performed in the presence of a carboxylic acid (MB), which is represented by formula (III), R4-[O]q-[CH2CH2-O]p-CH2COOH (III)wherein R4is selected from saturated or unsaturated, linear or branched C1to C30hydrocarbyl groups, preferably C1 to C22 hydrocarbyl groups, and more preferably C6 to C18 hydrocarbyl groups, q is 0, and p is 0, and preferably is oleic acid. It is also particularly advantageous to prepare the alkaline earth metal catalyst (MC) by first dispersing the alkaline earth metal compound (MA) in an alcoholsolvent, preferably an alcohol solvent having 1 to 5 carbon atoms, more preferablypropan-2-ol, or a mixture thereof with water, after which the reaction mixture isfurther treated with the acid (AC). For the reaction by which the alkaline earth metal catalyst (MC) is obtained, any common reactor may be employed, preferably a reactor with an agitating / mixing means, such as, e.g., a magnetic stirrer, a mechanical stirrer, a static mixer, a blender, a batch disperser, or a Rotor-Stator disperser. The preparation of the catalyst (MC) is preferably carried out under a pressure of from 0.5 to 2 bar, more preferably from 0.8 to 1.5 bar, even more preferably from 0.9 to 1.2 bar. In a preferred embodiment of the invention, the catalyst is prepared under atmospheric pressure. Furthermore, the catalyst (MC) is preferably prepared at a temperature of from -30 °C to 80 °C, preferably from -10 °C to 60 °C, more preferably from 0 °C to 50 °C. In a preferred embodiment of the invention, the catalyst is prepared at a temperature of from 20 to 40 °C, especially at room temperature. The thus prepared alkaline earth metal catalyst (MC), preferably the calcium catalyst, typically has a content of alkaline earth metal ions, preferably Ca2+ions, that is from 0.5 to 10 wt.-%, often from 1 to 7 wt.-%, often from 2.0 to 5.5 wt.-%. Optionally, the catalyst may be purged of volatile components, such as the solvent, water and other volatile byproducts by employing commonly used methods. Preferably, the volatile components are removed in vacuo, e.g. under a pressure below 0.8 bar, preferably below 0.3 bar, more preferably below 0.1 bar, and / or at elevated temperatures, e.g.50 to 180 °C, preferably 70 to 150 °C, morepreferably 80 to 140 °C.In a particularly preferred embodiment of the invention, the volatile compounds are removed on a rotary evaporator at a pressure below 0.1 bar and a temperature offrom 80 °C to 140 °C. Preferably, the mixture of glycerol ester alkoxylates of the formula (I) are preparedby a method comprising the steps ofi) introducing the catalyst (MC) as defined above and one or more glycerolesters of the formula (II) as described above into a pressure-resistantreactor;ii) optionally replacing the air in the reactor with nitrogen or other protectivegas;iii) optionally drying the reactor content at a temperature of from 50 to 200 °Cand / or a pressure below 0.8 bar;iv) heating the content of the reactor to a temperature of from 80 °C to 200 °C;v) optionally pressurizing the reactor with nitrogen or other protective gas to apressure of from 0.3 bar to 3.5 bar above atmospheric pressure;vi) pressurizing the reactor with alkylene oxide gas selected from the groupconsisting of ethylene oxide gas, propylene oxide gas and mixtures of ethylene oxide gas and propylene oxide gas to a pressure of from 1.5 bar to10 bar above atmospheric pressure with the proviso that the pressure is above the pressure prior to step vi);vii) allowing the mixture to react until the pressure in the reactor is constant.In step i), the catalyst (MC) may be introduced as obtained from the reaction of its preparation described above directly, or in its form that has been purged of volatile compounds, but preferably as obtained from the reaction of its preparation described above directly. The glycerol esters of formula (II) may be introduced in their raw form or may be purified prior to use. The catalyst (MC) is preferably introduced into the reactor in an amount from 0.5to 5 wt.-%, preferably from 1 to 3 wt.-%, more preferably from 1 to 2 wt.-% basedon the total weight of the mixture of glycerol esters of formula (II) and alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide. The pressure-resistant reactor is not particularly limited but is designed to withstand the pressures employed in the process, thus that it is not damaged during the process. Preferably, the reactor is designed to withstand pressures bothabove 10 bar, more preferably above 15 bar, and below 0.01 bar, more preferablybelow 0.001 bar. Preferably, the pressure-resistant reactor is an autoclave, morepreferably an autoclave equipped with an agitating means such as a magnetic or amechanical stirrer. Generally, the replacement of air in the reactor with nitrogen or other protective gas is not necessarily required, because the mixture of glycerol ester alkoxylates of the formula (I) would at least partially be generated in the process. However, air, particularly oxygen, in the reactor may lead to safety concerns during alkoxylation reactions in general and decomposition products due to oxidation and / or hydrolysis of the employed materials and of the generated products, especially at elevated temperatures. Therefore, it is advisable to carry out step ii) of the methodof the invention after step i).In general, the step of drying the reactor content is also not necessarily required, because the mixture of glycerol ester alkoxylates of the formula (I) would at least partially be generated in the process. However, water and alcohols may facilitate hydrolysis and transesterification of the employed materials and of the generated products under the reaction conditions. Especially if in step i) the catalyst (MC) is introduced into the reactor as obtained from the reaction of its preparation described above directly, it is advisable to carry out the drying step, since the directly obtained catalyst (MC) typically contains residues of polar solvents or their mixtures with water. In case the catalyst (MC) is purged of volatile components before introducing it into the reactor, the drying step iii) may be omitted. Nevertheless, in this case it may be advisable to carry out step iii) since volatile components may also be present as impurities in the one or more glycerol estersof formula (II). Therefore, in particularly preferred embodiments, step iii) is carriedout. The step iii) of drying the reactor content is typically performed at a temperature of from 50 °C to 200 °C, preferably of from 50 °C to 180 °C, more preferably of from60 °C to 150 °C, even more preferably of from 70 °C to 130 °C, particularly preferably of from 80 °C to 120 °C, and at a pressure below 0.8 bar, preferably below 0.1 bar, more preferably below 0.05 bar. The thus generated vacuum is preferably a dynamic vacuum. The vacuum pump for generating the vacuum is not particularly limited; it is, however, preferable to use an aspirator for generating the vacuum. Furthermore, it is advisable to reduce the pressure and increase temperature in the reactor gradually to prevent boiling retardation. In a particularly preferred embodiment, the step of drying the reactor content is carried out at a temperature of from 80 °C to 120 °C and a pressure below 0.01 bar, preferably over a period of at least15 minutes, more preferably over a period of at least 30 minutes, even morepreferably over a period of at least 1 hour. It is particularly preferred to dry the content of the reactor to constant mass. After the drying step iii), the fluid line between the vacuum pump and the reactor is interrupted, to ensure that the components added to the reactor after the drying remain in the reactor and are not directly withdrawn therefrom. Furthermore, it is preferable to compensate the vacuum in the reactor with nitrogen or other protective gas before carrying out the further steps, to reduce the risk of air entering the reactor. Step iv) of heating the content of the reactor is generally performed at a temperature of from 80 °C to 200 °C, preferably from 120 °C to 190 °C, morepreferably from 160 °C to 180 °C. This temperature is maintained at least untilstep vi) is finished, preferably until step vii) is finished.After setting the temperature in step iv), the reactor may be optionally pressurized in step v) with nitrogen or other protective gas to a pressure of from 0.3 to 3.5 bar, preferably of from 0.4 to 3.3 bar, more preferably of from 0.5 to 3.0 bar, even more preferably of from 0.7 to 2.5 bar and particularly preferably of from 0.8 to 2.2 bar above atmospheric pressure. By carrying out this step v), alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide introduced in the following step is diluted with the protective gas, thus that pressure-controlled dosage of alkylene oxide into the reactor is facilitated. In step vi) the reactor is further pressurized with alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide to a total internal pressure of from 1.5 to 10 bar, preferablyfrom 2 to 8 bar, more preferably from 3 to 6 bar, even more preferably from 4 to 5bar, above atmospheric pressure, with the proviso that the pressure in step vi) is above the pressure before step vi). During step vii), after introduction of the intended amount of alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide, the alkylene oxide inlet is closed and the reaction is allowed to proceed until the pressure in the reactor is constant. In the sense of the invention, the pressure is considered constant, if it does not change by more than 0.05 bar over a period of 15 minutes, preferably 30 minutes, more preferably 1 hour. It is particularly preferred that the pressure in the reactor does not change by more than 0.01 bar over a period of 1 hour. After completion of step vii), it is advisable to remove residual alkylene oxide fromthe reactor before isolating the mixture of glycerol ester alkoxylates of theformula (I), in order to prevent any unwanted reactions with alkylene oxide fromtaking place after isolation of the product. Preferably, residual alkylene oxide is removed from the reactor by cooling the reactor content to a temperature of from 50 to 120 °C, more preferably from 70 to 100 °C and even more preferably from 85to 95 °C, and employing a pressure of below 0.8 bar, preferably below 0.1 bar,more preferably below 0.05 bar. The thus generated vacuum is preferably adynamic vacuum. The vacuum pump for generating the vacuum is not particularly limited; it is, however, preferable to use an aspirator for generating the vacuum. Removal of residual alkylene oxide under these conditions is preferably carried outfor at least 10 minutes, more preferably at least 30 minutes and even morepreferably at least 1 hour. The method of isolation of the mixture of glycerol ester alkoxylates of the formula (I) is not particularly limited. However, it is preferable to isolate the product at elevated temperatures, specifically at temperatures of from 50 to 150 °C, preferably from 60 to 140 °C, more preferably from 80 to 120 °C. At these temperatures, the mixture of glycerol ester alkoxylates of the formula (I) is typically in a liquid state and has a sufficiently low viscosity, and therefore may be transferred out of the reactor more easily than in the solid state, e.g. by pouring the product out of the reactor or via a bottom valve, thereby minimizing the amount of residues in the reactor. Thus, the subsequent cleaning and maintenance of the reactor is also facilitated.The method for preparing the mixture of glycerol ester alkoxylates of the formula(I) using the catalyst (MC) described above may be interrupted at any stage, andcontinued at a later point in time, without the reaction time being significantly increased. In a preferred embodiment of the invention, the sum x+y+z in the mixtures of alkoxylates of the formula (I), is, based on a molar average, a number from 90 to 200, more preferably from 90 to 190 and even more preferably from 90 to 110 or from 160 to 190. In a particularly preferred embodiment of the invention, the sum x+y+z in the mixtures of alkoxylates of the formula (I), is, based on a molar average, a number from 90 to 110. In another particularly preferred embodiment of the invention, the sum x+y+z in the mixtures of alkoxylates of the formula (I), is, based on a molar average, a number from 160 to 190. Accordingly, in a preferred embodiment of the invention, the molar ratio of the alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide to the one or more glycerol esters of the formula (II) is from 90:1 to 200:1, more preferably from 90:1 to 190:1 and even more preferably from 90:1 to 110:1 or from 160:1 to 190:1. In a particularly preferred embodiment of the invention, the molar ratio of the alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide to the one or more glycerol esters of the formula (II) is from 90:1 to 110:1. In another particularly preferred embodiment of the invention, the molar ratio of the alkylene oxide selected from the group consisting of ethylene oxide, propylene oxide and mixtures of ethylene oxide and propylene oxide to the one ormore glycerol esters of the formula (II) is from 160:1 to 190:1.

During the preparation of the mixture of glycerol ester alkoxylates of the formula (I), by-products may be formed. The formation of by-products in chemical reactions is quite normal since these reactions usually do not take place with a selectivity of 100 %. However, in case by-products are formed during the preparation of the mixture of glycerol ester alkoxylates of the formula (I), these by- products are formed in an amount of preferably less than 25.0 wt.-%, more preferably less than 20.0 wt.-%, even more preferably less than 15.0 wt.-%, particularly preferably less than 10.0 wt.-%, extraordinarily preferably less than 6.0 wt.-% and especially preferably less than 5.0 wt.-%, in each case based on the combined total weight of the mixture of glycerol ester alkoxylates of the formula (I) and the by-products, and in particular in case the mixture is prepared as described herein.

Examples MethodsProcedure for Examples 2, 6, 7, 8: Sodium Cocoyl Isethionate and water aremixed in a beaker with slightly heating until the Sodium Cocoyl Isethionate isdissolved. The mixture is cooled down and the thickener (Example 1) is added.The mixture is stirred until everything is well distributed. Betaine and preservativeare added one after the other while stirring. The pH is adjusted with NaOH (10%) / Citric acid (20%).Procedure for Examples 3, 9: Sodium Cocoyl Isethionate and water are mixed in abeaker with slightly heating until the Sodium Cocoyl Isethionate is dissolved. Themixture is cooled down and the thickener (Example 1) is added. The mixture isstirred until everything is well distributed. Glucamide and preservative are addedone after the other while stirring. The pH is adjusted with NaOH (10%) / Citric acid(20%). Procedure for Examples 4, 5: Thickener (Example 1) and water are added to a beaker and stirred until everything is well distributed. SLES and Betaine are added one after the other while stirring. The preservative is added and the pH is adjusted with NaOH (10%). Viscosity measurementThe viscosity was determined 24 h after preparation of the composition. For thispurpose, the sample was tempered for at least 2 h at 20 °C. The viscosity wasmeasured with a Brookfield viscometer (20 °C, 20 rpm). Transmission measurement The transmission was determined using the Lumisizer. For this purpose, the sample was filled into a cuvette (LUM 2mm, PC, Rect. Synthetic Cell (110-131xx)). The measurement was carried out at 25°C at a speed of 200 rpm for 1 minute (6 profiles, 10s interval). The transmission was calculated by integration. In Examples 2 to 10, the ratios of the surfactants are weight ratios. In Examples 2to 10, the active contents of the surfactants, the active contents of the thickeners,and the salt contents are percentages by weight of the respective compositionthey refer to. Example 1 Synthesis of inventive glycerol ester alkoxylates I-1, I-2, I-3, I-4, I-5 and I-6 (from high oleic sunflower oil, palm oil and refined rapeseed oil) Preparation of calcium catalyst: A mixture of 1047.0 g of a carboxylic acid under the trade name “EmulsogenTMCOL 050” marketed by Clariant Produkte (Deutschland) GmbH, 55.8 g of calcium hydroxide and 360.6 g of propan-2-ol was agitated at ambient temperature for 5 minutes with a batch disperser (Ultra Turrax from IKA Werke GmbH & Co KG). After this, 44.2 g of concentrated sulfuric acid were added over two minutes and the mixture was again agitated for 5 minutes with the batch disperser, providing a catalyst with a Ca2+content of 2.00 wt.-%. General alkoxylation procedure: The glycerol ester of the corresponding oil and the catalyst were placed into a glass autoclave, which was then flushed with nitrogen by alternatingly applying vacuum and introducing nitrogen (3 cycles). The mixture was dried under aspirator vacuum at 120°C for 15 minutes. The pressure in the autoclave was restored to ambient with nitrogen and heated to 160°C. At this temperature the autoclave was pressurized with nitrogen to a pressure of 1.0 bar above atmospheric pressure, after which pressure-controlled dosage of alkylene oxide, preferably ethylene oxide, took place up to a maximum pressure of 5.5 bar above atmospheric pressure. The alkoxylation is carried out in a semi-batch process with automated dosage of additional alkylene oxide within a given temperature window and up to the specified maximum pressure. The pressure is adjusted according to the increasedfilling volume of the vessel. After introduction of the intended amount of alkyleneoxide and closing the alkylene oxide inlet, the reaction was continued until the pressure became constant. The reactor content was cooled to 100°C and aspirator vacuum was applied for 60 minutes to remove residual alkylene oxide. The temperature was reduced to 80°C and the final product was transferred into storage vessels and analyzed. The typical batch scale was 400 g to 2000 g. The uptake of the intended amount of alkylene oxide is assured by gravimetry and by determination of the saponification value according to DIN EN ISO 3681.
