Temperature-stable emulsions

Abstract

The invention relates to a cosmetic emulsion.

Description

Background Art

[0001] Cosmetics are often used not only to make people look beautiful and attractive, but also play a decisive role in improving people's self-esteem and sense of well-being. Therefore, a wide variety of cosmetics are used for daily cleansing and care of human skin.

[0002] Skin care products usually consist of emulsions. An emulsion usually refers to a heterogeneous system consisting of two liquids that are immiscible or only miscible with each other to a limited extent, usually called phases, in which one of the two liquids is dispersed in the other liquid in the form of fine droplets. From the outside and with the naked eye, an emulsion appears homogeneous.

[0003] If the two liquids are water and oil, and the oil droplets are finely distributed in the water, it is an oil-in-water emulsion (O / W emulsion, such as milk). The essential features of an O / W emulsion are brought out by the water. A water-in-oil emulsion (W / O emulsion, such as butter) involves the opposite principle, wherein the essential features are determined here by the oil.

[0004] For the stabilization and thickening of O / W emulsions, acrylate-based polymers are usually incorporated into these formulations. Acrylate-based polymers are polymers obtained by homopolymerization or copolymerization with acrylic acid and / or methacrylic acid. Examples of this are, in particular, carbomers or acrylate copolymers.

[0005] Emulsions with acrylates are known, inter alia, from DE 10148825 A1, DE 19938756 A1 and DE 29924371 U1.

[0006] Formulations with acrylate-based polymers have a number of advantages. For example, these formulations are often characterized by low viscosity. In addition, the formulations are well protected from flocculation and / or agglomeration during long-term storage (e.g. storage at -10°C for more than 30 days). If a formulation is stored at -10°C for 30 days and then warmed to 20°C, it is described as soft and smooth.

[0007] However, the use of these acrylate-based polymers has been increasingly criticized because their biodegradability has not been fully elucidated.

[0008] A disadvantage of the prior art is that it is difficult to reconcile low viscosity with temperature stability, which prevents flocculation or caking when stored for several months at -10°C, without using acrylate-based polymers. It is known to those skilled in the art to use short-chain diols, which lead to better temperature stability but at the same time increase the viscosity of the formulation. The use of a single biopolymer or different combinations generally results in insufficient temperature stability or high viscosity. Summary of the invention

[0009] Surprisingly, the present invention can solve the problems of the prior art.

[0010] The object of the present invention is an acrylate-free cosmetic emulsion having:

[0011] a) an emulsifier system, which forms a liquid crystal network in the emulsion;

[0012] b) hydroxypropyl starch phosphate and / or distarch phosphate;

[0013] c) Gellan gum.

[0014] By definition, acrylate-free means free of polymers obtained by homopolymerization or copolymerization with acrylic acid and / or methacrylic acid.

[0015] By definition, fatty alcohols have a C-10 to C-20 carbon chain. Therefore, the alcohol residue of the fatty alcohol glucoside also has such a carbon chain.

[0016] By definition, the presence of an emulsifier system leads to the formation of a liquid crystal network in the formulation. A liquid crystal network is characterized and defined by the formation of a liquid crystal structure. By definition, the emulsifier system must contribute to the formation of a liquid crystal structure.

[0017] A subject of the present invention is also the use of the emulsion according to the invention for providing a cosmetic product.

[0018] Advantageously, it is an oil-in-water (O / W) emulsion.

[0019] If weight percentages (wt%) are given below without mentioning a specific composition or a concrete mixture, these data should always refer to the total weight of the cosmetic emulsion. If ratios of components / substances / substance groups are disclosed below, these ratios refer to the weight ratios of the components / substances / substance groups mentioned.

[0020] If weight percent ranges for ingredients of cosmetic emulsions are given below, the disclosure of the present application also includes all individual values ​​within these weight percent ranges in steps of 0.1 weight percent.

[0021] The expressions “according to the invention”, “advantageously according to the invention”, “advantageous in the sense of the invention” always refer to the preparations according to the invention and the use according to the invention.

[0022] Unless otherwise stated, all tests were performed under normal conditions. The term "normal conditions" refers to 20°C, 1013 hPa and 50% relative humidity.

[0023] If the term "skin" is used it preferably refers to human skin.

[0024] If viscosity values ​​are given in the present disclosure, all values ​​refer to measurements carried out at 25° C. using a Rheomat R 123 from proRheo in a 150 ml wide-necked bottle (VWR number: 807-001). The Rheomat R 123 from proRheo GmbH is a rotational viscometer, i.e. the measuring body rotates in the substance to be measured. The force required to rotate the sample in the sample at a given rotational speed is measured. The viscosity is calculated from this torque, the rotational speed of the measuring body and the geometric dimensions of the measuring system used. Measuring body No. 2 (article number 200 0192) was used as the measuring body with a speed range of 62.5 min -1 .

[0025] According to the invention, the emulsion has an emulsifier system which forms a liquid crystal network in the emulsion.

[0026] The presence of such a network is therefore a characteristic of the emulsion according to the invention. It is advantageously a liquid crystal gel network.

[0027] Surprisingly, it has been found that the gel network formed specifically in the present invention, in combination with the other components of the present invention, can provide acrylate-free emulsions which also show less agglomeration when stored at -10°C.

[0028] The emulsifier system according to the invention advantageously comprises at least one fatty alcohol glucoside. Advantageously, the fatty alcohol glucoside is selected from the group having the INCI name: Arachidyl Glucoside; C10-16 Alkyl Glucoside; C12-18 Alkyl Glucoside; C12-20 Alkyl Glucoside; Cocoyl Glucoside; C9-11 Alkyl Glucoside; Octyl / Decyl Glucoside; Octyl Glucoside; Cetearyl Glucoside; Decyl Glucoside; Isostearyl Glucoside; Lauryl Glucoside; Myristyl Glucoside and / or Undecyl Glucoside.

[0030] It is also advantageous if the total weight proportion of arachidyl glucoside; C10-16 alkyl glucoside; C12-18 alkyl glucoside; C12-20 alkyl glucoside; cocoyl glucoside; C9-11 alkyl glucoside; octyl / decyl glucoside; octyl glucoside; cetearyl glucoside; decyl glucoside; isostearyl glucoside; lauryl glucoside; myristyl glucoside and / or undecyl glucoside is 0.1 to 5.0% by weight, preferably 0.5 to 3.5% by weight, preferably 0.6 to 2.5% by weight and particularly preferably 0.9 to 2.2% by weight, in each case relative to the total weight of the emulsion.

[0034] Furthermore, it is advantageous if the emulsifier system includes disodium cetearyl sulfosuccinate. If disodium cetearyl sulfosuccinate is present, the total weight of disodium cetearyl sulfosuccinate is advantageously 0.01 to 0.5% by weight, preferably 0.02 to 0.2% by weight, in particular 0.04 to 0.10% by weight, relative to the total weight of the emulsion.

[0035] It is also advantageous if the emulsifier system comprises glyceryl stearate. If glyceryl stearate is present, the total proportion of glyceryl stearate is advantageously 0.1 to 1.8% by weight, preferably 0.5 to 1.5% by weight, in particular 0.7 to 1.2% by weight, relative to the total weight of the emulsion.

[0037] Liquid crystal structures in emulsions can be visualized by optical microscopy using polarized light. See “Study on the Formation and Properties of Liquid Crystal Emulsion in Cosmetic”, Wanping Zhang*, Lingyan Liu, School of Flavor and Fragrance Technology, Shanghai University of Technology, Shanghai, China, Journal of Cosmetics, Dermatological Sciences and Applications, 2013.

[0038] Advantageously, the liquid crystal structure in the emulsion of the invention is present as a globular structure, which can be identified by the appearance of a typical Maltese cross in polarized light microscopy images.

[0039] In addition, the emulsion of the present invention contains at least hydroxypropyl starch phosphate and / or distarch phosphate. Advantageously, the total proportion of hydroxypropyl starch phosphate and / or distarch phosphate is 0.1 to 3.0% by weight, preferably 0.2 to 1.5% by weight, particularly preferably 0.25 to 0.9% by weight, relative to the total weight of the emulsion.

[0040] Furthermore, the emulsion according to the invention comprises gellan gum. Advantageously, the proportion of gellan gum is 0.01% to 0.5% by weight, preferably 0.03% to 0.3% by weight, particularly preferably 0.04 to 0.2% by weight, relative to the total weight of the emulsion.

[0041] It is also advantageous to additionally contain xanthan gum. If xanthan gum is present, the proportion of xanthan gum is 0.01% to 0.5% by weight, preferably 0.03% to 0.3% by weight, particularly preferably 0.04 to 0.2% by weight, relative to the total weight of the emulsion.

[0042] Furthermore, it is advantageous to additionally contain further polysaccharides. These further polysaccharides can advantageously be selected from the group consisting of further polysaccharides of polysaccharide gums, starches and / or celluloses.

[0043] Among the polysaccharide gums, particular preference is given to using the substances having the INCI names guar gum, sclerotium gum and / or tara gum.

[0044] Among the starches, preference is given to using those having the INCI name corn starch, sodium hydroxypropyl starch phosphate, sodium carboxymethyl starch, tapioca starch and / or modified potato starch.

[0045] Among the celluloses, preference is given to those having the INCI names ethylcellulose, microcrystalline cellulose, cellulose gum, hydroxyethylcellulose, carboxymethylhydroxyethylcellulose, hydroxyethylethylcellulose, hydroxymethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose and / or hydroxyethylcellulose.

[0046] The proportion of the further polysaccharide in the emulsion is advantageously 0.01 to 4% by weight, preferably 0.3 to 2.5% by weight, preferably 0.5 to 1.5% by weight and particularly preferably 0.6 to 1.0% by weight, relative to the total weight of the emulsion.

[0047] The proportion of the further polysaccharide gum in the emulsion is advantageously 0.01 to 4% by weight, preferably 0.3 to 2.5% by weight, preferably 0.5 to 1.5% by weight, particularly preferably 0.6 to 1.0% by weight, relative to the total weight of the emulsion.

[0048] The proportion of the additional starch in the emulsion is advantageously 0.01 to 4% by weight, preferably 0.3 to 2.5% by weight, preferably 0.5 to 1.5% by weight and particularly preferably 0.6 to 1.0% by weight, relative to the total weight of the emulsion.

[0049] The proportion of cellulose in the emulsion is advantageously from 0.01 to 4% by weight, preferably from 0.3 to 2.5% by weight, preferably from 0.5 to 1.5% by weight and particularly preferably from 0.6 to 1.0% by weight, relative to the total weight of the emulsion.

[0050] Advantageously, the total proportion of ethylcellulose, microcrystalline cellulose, cellulose gum, hydroxyethylcellulose, carboxymethylhydroxyethylcellulose, hydroxyethylethylcellulose, hydroxymethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose and / or hydroxyethylcellulose in the emulsion is from 0.01 to 4% by weight, preferably from 0.3 to 2.5% by weight, preferably from 0.5 to 1.5% by weight, particularly preferably from 0.6 to 1.0% by weight, relative to the total weight of the emulsion.

[0051] In the prior art, short-chain diols with 3 to 5 carbon atoms, such as butanediol or 1,2-propylene glycol, are often added to the emulsions to prevent flocculation / caking of the formulation ingredients at -10°C. It has now surprisingly been found that this anti-freezing stability is achieved even in the absence of these substances. It can be assumed that the polymers according to the invention contribute to the stabilization by interaction with the liquid crystal structures formed. Furthermore, it has surprisingly been found that formulations that do not contain short-chain diols with 3 to 5 carbon atoms have a significantly reduced viscosity. Low viscosity is particularly a problem in formulations that do not contain acrylates.

[0052] Therefore, it is preferred according to the invention that the proportion of short-chain diols having 3 to 5 carbon atoms is less than 0.5% by weight, preferably less than 0.25% by weight, preferably less than 0.1% by weight, particularly preferably 0.0% by weight, relative to the total weight of the emulsion. It is therefore preferred that no short-chain diols having 3 to 5 carbon atoms are contained.

[0053] Furthermore, the emulsion advantageously comprises at least one wax component having a melting point below 43°C.

[0054] Advantageously, at least one wax component is included, the melting point of which is in the range of 25° C. to 43° C. The presence of such a low-melting wax component ensures that the preparation melts on human skin. At the same time, surprisingly, the consistency can be substantially maintained, especially at temperatures around 45° C. Furthermore, surprisingly, phase separation at 45° C. is prevented.

[0055] By definition, fatty acids and fatty alcohols having an alkyl chain of 10 to 20 carbon atoms do not belong to the wax components.

[0056] Advantageously, the total content of wax components with a melting point in the range from 25° C. to 43° C. is 0.5 to 5% by weight, preferably 1 to 4.5% by weight, particularly preferably 1.5 to 3.5% by weight, relative to the total weight of the emulsion.

[0057] Preferred wax components within the melting point range are myristyl myristate, hydrogenated coconut glycerides and / or cetyl ricinoleate.

[0059] If myristyl myristate is present, it is advantageous if the proportion of myristyl myristate is 0.5 to 5.5% by weight, preferably 1.0 to 4.5% by weight, particularly preferably 1.4 to 3.0% by weight, relative to the total weight of the emulsion. If hydrogenated coconut oil glycerides are present, it is preferred if the proportion of hydrogenated coconut oil glycerides is 0.1 to 3.0% by weight, preferably 0.3 to 2.0% by weight, preferably 0.5 to 1.5% by weight, relative to the total weight of the emulsion. If cetyl ricinoleate is present, it is preferred if the proportion of cetyl ricinoleate is 0.01 to 3.0% by weight, preferably 0.05 to 1.0% by weight, preferably 0.1 to 0.5% by weight, relative to the total weight of the emulsion.

[0060] Furthermore, it is advantageous according to the invention that no high melting point waxes with a melting point above 43° C. are contained or their proportion is less than 0.5% by weight of the emulsion. Surprisingly, a formulation that is stable at 45° C. can be provided without adding a high melting point wax component. It can be assumed that the formation of a liquid crystal structure at 45° C. achieves stability of the formulation to prevent phase separation and thus achieve consistency.

[0061] It is also advantageous if the emulsion contains one or more oil components that are liquid under normal conditions. It is generally preferred that the proportion of the oil component that is liquid under normal conditions is 0.2 to 5.0% by weight, preferably 0.5 to 4.0% by weight, particularly preferably 1.5 to 2.5% by weight, relative to the total weight of the emulsion.

[0062] The oil advantageously contained is selected from natural oils. The natural oil advantageously contained is selected from the following group: avocado oil, babassu seed oil, argan oil, almond oil, jojoba seed oil, shea butter, coconut oil, milk thistle seed oil, evening primrose oil, olive oil, sunflower seed oil, grape seed oil, vegetable oil, cottonseed oil, burdock seed oil, macadamia oil, macadamia seed oil, corn germ oil, sweet almond oil, castor seed oil, rapeseed oil and / or soybean oil. If containing natural oils, the total content of these oils is advantageously 0.01 to 3 weight %, preferably 0.1 to 1.0 weight %, particularly preferably 0.2 to 0.7 weight %, relative to the total weight of the emulsion.

[0063] It is also advantageous to contain one or more esters of coconut fatty alcohol. In this context, particular preference is given to using coconut caprylate / caprate. If coconut fatty alcohol esters are present, the proportion of these esters is advantageously 0.2 to 4% by weight, preferably 0.4 to 2.5% by weight, particularly preferably 0.8 to 1.5% by weight, relative to the total weight of the emulsion. If coconut caprylate / caprate is present, the proportion of coconut caprylate / caprate is advantageously 0.2 to 4% by weight, preferably 0.4 to 2.5% by weight, particularly preferably 0.8 to 1.5% by weight, relative to the total weight of the emulsion.

[0064] It is also preferred that one or more oils are contained which are triglycerides of three identical fatty acids. Particularly preferred is triisostearin. If triglycerides of three identical fatty acids are contained, the proportion of triglycerides is advantageously 0.05 to 2% by weight, preferably 0.08 to 1.0% by weight, particularly preferably 0.1 to 0.5% by weight, relative to the total weight of the emulsion. If triisostearin is contained, the proportion of triisostearin is advantageously 0.05 to 2% by weight, preferably 0.08 to 1.0% by weight, particularly preferably 0.1 to 0.5% by weight, relative to the total weight of the emulsion.

[0065] It is also advantageous to contain one or more fatty alcohols having 16 to 24 carbon atoms, wherein the total proportion of these fatty alcohols is 0.01 to 1.5% by weight, preferably 0.1 to 0.3% by weight, relative to the total weight of the emulsion. In particular, cetearyl alcohol is contained in a proportion of 0.01 to 1.5% by weight, preferably 0.1 to 0.3% by weight, relative to the total weight of the emulsion.

[0066] It has also been found to be advantageous if the emulsion contains one or more fatty acids having 14 to 24 carbon atoms, wherein their proportion is advantageously 0.2 to 5.0% by weight, preferably 1.5 to 4% by weight, particularly preferably 1.8 to 3.0% by weight, relative to the total weight of the emulsion.

[0067] Furthermore, the emulsion according to the invention is preferably characterized in that it contains glycerol in a proportion of 0.5% to 15% by weight, preferably 3.0 to 7% by weight, relative to the total weight of the emulsion.

[0068] Furthermore, it is advantageous within the meaning of the invention if the emulsion contains phenoxyethanol, dehydroacetic acid, benzyl alcohol and / or ethylhexylglycerol.

[0069] If the emulsion contains benzyl alcohol, the proportion of benzyl alcohol is preferably from 0.05% to 0.5% by weight, based on the total weight of the emulsion.

[0070] If the emulsion contains phenoxyethanol, it is preferred that the total proportion of phenoxyethanol is 0.1% to 1.2% by weight, relative to the total weight of the emulsion.

[0071] If the emulsion contains ethylhexylglycerin, it is preferred that the proportion of ethylhexylglycerin is from 0.1% to 1.0% by weight, relative to the total weight of the emulsion.

[0072] Furthermore, advantageously, embodiments of the invention are characterized in that they contain ethanol. If the emulsion contains ethanol, the proportion of ethanol is preferably 0.5% to 10% by weight, preferably 1.5% to 5.0% by weight, relative to the total weight of the emulsion.

[0074] Furthermore, advantageous emulsions according to the invention are characterized in that they contain water in a proportion of 60% to 95% by weight, preferably 70% to 90% by weight, relative to the total weight of the emulsion.

[0075] Furthermore, an emulsion advantageous according to the invention has a viscosity of 8000 mPa·s to 30000 mPa·s 24 hours after production. If viscosity is mentioned in the present disclosure, all values ​​refer to measurements made at 25° C. in a 150 ml crimped glass using a Rheomat R 123 from proRheo GmbH. The Rheomat R 123 from proRheo GmbH is a rotational viscometer, i.e. a measuring body that rotates in the substance to be measured. The force required to rotate the measuring body in the sample at a given rotational speed is measured. The viscosity is calculated from this torque, the rotational speed of the measuring body and the geometric dimensions of the measuring system used. Measuring body No. 2 (article number 2000192) was used as the measuring body with a rotational speed range of 62.5 min -1 All viscosity measurements were always performed 24 hours after emulsion production. DETAILED DESCRIPTION

[0076] Comparative Tests and Examples

[0077] The following examples are intended to illustrate the present invention without limiting it. Unless otherwise indicated, all amounts, ratios and percentages are based on weight and total amount or the total weight of the preparation.

[0078] The following table with Examples 1 to 11 shows different formulations. Example 1 is an example not according to the invention and represents a common formulation with an acrylate-based polymer carbomer. The formulation of Example 1 was investigated after storage for 30 days at -10°C and subsequent thawing to 20°C. The formulation has low viscosity. In addition, after thawing, there are few lumps and it is correspondingly homogeneous, smooth and soft. The formulation does not have a liquid crystal structure.

[0079] Example 2 is an example not according to the invention in which the polymer addition was omitted. The same storage and thawing process was adopted as in Example 1. The formulation is characterized by low viscosity, but a significant increase in caking after thawing.

[0080] Examples 3 to 7 are also reference examples not according to the invention which tend to intensify agglomeration after thawing. Different polymers were used here.

[0081] Examples 8 to 10 are exemplary formulations according to the invention. They have a spherical liquid crystal structure that can be detected by a polarized light optical microscope. Surprisingly, it was found that the presence of a liquid crystal structure in combination with the polymer according to the invention leads to a stabilization of the formulation in terms of agglomeration after thawing. In addition, it was surprisingly found that there was a low viscosity. Therefore, the disadvantages of abandoning acrylate-containing polymers are alleviated by the present invention.

[0082] Example 11 is an example not according to the invention which shows that the addition of a glycol (such as butanediol) can achieve freeze stability at -10°C, but a significant, undesirable increase in viscosity occurs.

[0083] Sensory evaluation method for the viscosity of this emulsion:

[0084] 1. Divide the inner side of the forearm into two test areas

[0085] 2. Wash the corresponding parts of the arms and hands (not the entire forearm)

[0086] 3. After waiting for 3 minutes, apply 200μl of lotion to the center of your palm

[0087] 4. The lotion was then distributed over the test surface using circular motions (one circle per second) across the palm of the hand.

[0088] 5. Disperse the emulsion until the product is absorbed (up to 90 seconds)

[0089] 6. Then press the palm of your hand once on the test site (the area between the inner and outer sides of the forearm) and evaluate the stickiness attribute (0 not sticky, 5 very sticky)

[0090] The subjects underwent six measurements for each formulation.
