Description

Face Cleansing Composition containing Amino Acid Surfactants Technical field
The present invention describes a cosmetic cleansing composition, particularly a face cleansing composition based on an amino acid surfactant system. The composition may smoothly be dispensed from the packaging device, particularly a tube. Upon foaming the composition builds up a dense and creamy foam. Moreover, the skin is cleansed in an effective way without being irritated.
Background art
In general, cleansing products are supposed to cleanse the skin and hair. Cleansing products for the skin are primarily used to remove dirt from the skin surface. External solid or liquid components, which came into contact with the skin and were deposited thereupon, or components applied to the skin, are part of the dirt on the skin, which is to be removed. Furthermore, the dirt on the skin also includes excess skin lipids and dead cells. By the aid of surfactants in the cleansing compositions, the components of the dirt are solubilized and removed from the surface of the skin during rinsing off.
Cleansing compositions intended for face cleansing have to meet special requirements. As the skin of the face is a very sensitive part of the skin, the eye area and the eyes being even more sensitive, cleansing compositions for face cleansing have to be compatible to the skin of the face and the eyes. Furthermore, the compositions have to be distributed on the skin easily, without the necessity of intense rubbing, which may lead to skin irritations.
Additionally, cleansing compositions, which are intended to be used by men, have to be efficient in cleansing while easy to handle. Analyzing consumer tests and questionnaires, it became apparent that men preferred cleansing compositions provided in a tube.
Hence, there was a need to provide mild cleansing compositions, which are made available in tubes. For this purpose, the composition must have a texture and consistency, which allows an easy dispensing from said packaging device. Moreover, the compositions have to be stable, at least over the shelf storage time.
To meet the criterion of mildness amino acid surfactants may be incorporated in the cleansing compositions.
The use of amino acid surfactants in cleansing compositions is described in prior art.
WO 2019/114274 A1 describes a shaving cream, which may be used for cleansing as well. This composition contains an amino acid surfactant system consisting of sodium lauroyl glutamate and sodium cocoyl glycinate and glycerol in an amount 2 to 10 parts.
CN 107773456 A discloses a facial cleanser also containing sodium lauroyl glutamate and sodium cocoyl glycinate and glycerin in an amount of 5 %.
CN 111671659 A describes a cleansing cream comprising sodium cocoyl glycinate and 10 to 20%glycerin.
CN 111467290 A discloses an amino acid facial cleanser containing octyldodecanol lauroyl glutamate and potassium cocoyl glycinate.
The problem to be solved by the present invention is to provide a cleansing composition, particularly for face cleansing, which has a consistency being adapted to an easy dispensing from a tube, has a good cleansing efficiency and foam performance, and is still mild to the skin.
Surprisingly, the problem was solved by a cosmetic cleansing composition containing
- an amino acid surfactant system consisting of sodium alkyl glycinate and potassium alkyl glycinate,
- glycerol in an amount greater than 25 %by weight, referring to the total weight of the composition.
Likewise, preferably, no further amino acid surfactants are contained, even more preferably no further anionic surfactants are contained in the composition of the present invention.
In the composition of the present invention the amino acid surfactant system consisting of sodium alkyl glycinate and potassium alkyl glycinate is contained in an amount of 10 to 30%by weight, preferably 12 to 20%by weight, referring to the total weight of the composition and referring to the active content of each surfactant. Sodium alkyl glycinate is contained in an amount of 1 to 5%by weight, preferably 3 to 4%by weight, referring to the total weight of the composition and referring to the active content. Potassium alkyl glycinate is contained in an  amount of 8 to 25%by weight, preferably 10 to 20%by weight, referring to the total weight of the composition and referring to the active content.
The alkyl residue of sodium alkyl glycinate and potassium alkyl glycinate may comprise 6 to 22 carbon atoms. The alkyl residue may consist of a definite number of carbon atoms or may be a mixture, which may be obtained from natural oils or fats, like palm oil, soybean oil and coconut oil. According to the present invention it is preferred, if the alkyl residues are derived from fatty acids contained in the triglycerides of coconut oil. Hence, it is preferred, if sodium cocoyl glycinate and potassium cocoyl glycinate are contained in the composition of the present invention.
Advantageously, sodium alkyl glycinate and potassium alkyl glycinate are contained in specific weight ratio, namely a weight ratio between sodium alkyl glycinate and potassium alkyl glycinate in the range of 3: 1 to 1: 10, preferably 2: 1 to 1: 4, and more preferably 1: 1 to 1: 2.3.
The composition of the present invention is an aqueous composition, preferably containing 5 to 35%by weight, more preferably 10 to 30%by weight water, referring to the total weight of the composition.
According to the present invention glycerol has to be present in an amount greater than 25 %by weight, referring to the total weight of the composition. Preferably, glycerol is contained in an amount of 25 to 40%by weight, more preferably 30 to 39%by weight, referring to the total weight of the composition. In the composition according to the present invention the high amount of glycerol contributes to build up a structure in the composition and thereby helps to provide a suitable consistency, which allows a smooth dispensing out of the tube.
Additionally, one or more thickening agent (s) may be contained in the composition according to the present invention. Thickening agents may also be referred to as hydrocolloids". Hydrocolloids are macromolecules being build up in a largely linear manner; however intramolecular and intermolecular interactions enable the formation of a network-like structure. Hydrocolloids are partially water-soluble natural or synthetic polymers that form gels or viscous solutions in aqueous systems. They increase the viscosity of the water either by binding water molecules (hydration) or by absorbing water in spaces in the interacting macromolecules, thereby restricting the mobility of the water. Such water-soluble polymers represent a large group of chemically very different natural and synthetic polymers, the common feature of which is their solubility or swellability in water or aqueous media. This property is due to a sufficient number of hydrophilic groups and only a limited crosslinking. The hydrophilic groups can be nonionic, anionic or cationic in nature.
The group of cosmetically and dermatologically relevant hydrocolloids can be divided into:
- organic, natural compounds such as agar-agar, carrageenan, tragacanth, gum arabic, alginates, pectins, polyoses, guar flour, carob gum, starch, dextrins, gelatine, casein,
- organic, modified natural substances, such as carboxymethyl cellulose and other cellulose ethers, hydroxyethyl and -propyl cellulose and the like,
- organic, fully synthetic compounds, such as polyacrylic and polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides,
- inorganic compounds, such as polysilicic acids, clay minerals such as montmorillonites, zeolites, silicas.
According to the present invention it is preferred, if hydrocolloids are contained, which are fully synthetic compounds, in particular polyacrylic and/or polymethacrylic compounds. Polyacrylates may be homopolymers of acrylic acid, which are then referred to as carbomers. An advantageous carbomer may be obtained from Lubrizol Advanced Materials under the trade name Carbopol 980, for example.
It is preferred, if copolymers containing (meth-) acrylic acid and further monomers are contained in the composition of the present invention. It is more preferred, if the further monomers are alkyl acrylates and/or alkyl methacrylates, even more preferred having alkyl radicals with 10 to 30 carbon atoms (C10-C30) . For example, such a polymer is an Acrylates/C10-C30 Alkylacrylate Crosspolymer (INCI name) , which is available from Lubrizol Advanced Materials under the trade name Carbopol ETD 2020.
The copolymers containing (meth-) acrylic acid and further monomers, especially those where the further monomers are chosen from C10-30 alkyl acrylates, contribute to the building of a network structure, particularly in combination with the relatively high amounts of glycerol. In said combination the amount needed of the additional thickening agent can be reduced.
If in the composition of the present invention at least one thickening agent is contained, the at least one thickening agent is contained in a total amount of 0.05 to 1.5%by weight, preferably 0.3 to 0.7%by weight, referring to the total weight of the composition and referring to the active content.
Likewise, advantageously at least one organic acid is contained in the composition of the present invention. It is preferred, if the organic acid is citric acid. If at least one organic acid is contained, the at least one organic acid is contained in a total amount of 0.1 to 2.0%by weight, preferably 0.2 to 1.5 %by weight, referring to the total weight of the composition.
By adding the at least one organic acid a specific pH value is adjusted. The pH values are in the range of 6.20 to 7.00, preferably 6.50 to 6.90.
The addition of the at least one organic acid, particularly citric acid, has an effect on the amino acid surfactants, namely sodium alkyl glycinate and potassium alkyl glycinate. Without being bound to theory, it may be assumed that at pH values around the pK a half of alkyl glycinate molecules are present in a protonated form and the other half in dissociated form, both of which are interacting through hydrogen bonding. Moreover, the alkyl residues are also interacting thereby establishing a kind of double layer structure. If these structures are assembling a lamellar structure is built up.
If the pH value increases micellar structures may form or if sufficient cations are present, the acidic groups will interact via the cations building up a similar structure as at a pH value around the pK a value. Hence, flat lamellar structures may form and stabilize the composition and contribute to a suitable consistency. Besides, spherical crystalline structures may also be generated. Aphoto of a composition according to the invention (Example 1) showing lamellar structures (indicated by long arrows) and spherical crystalline structures (indicated by short arrows) is shown in Figure 1. The photo was taken using a polarizing microscope of the company Nikon, type ECLIPSE Ci-POL; the magnification was 550 x.
In the composition of the present invention at least one further surfactant chosen from amphoteric surfactants may be contained.
Amphoteric surfactants may be classified in the following groups:
1. Acyl/dialkyl ethylenediamine, for example sodium acylamphodiacetate, disodium acylamphodipropionate, disodium alkylamphodiacetate, sodium acylamphohydroxypropylsulfonate, disodium acylamphodiacetate and sodium acylamphopropionate,

According to the present invention it is preferred, if at least one amphoteric surfactant, chosen from the group of betaines, particularly from alkyl amidopropylbetaines, is contained. It is more preferred, if Cocamidopropyl betaine is contained.
If at least one amphoteric surfactant is contained in the composition of the present invention, the at least one amphoteric surfactant is contained in a total amount of 1 to 6%by weight, preferably 3 to 5%by weight, referring to the total weight of the composition and referring to the active content.
Additionally, in the composition of the present invention at least one emollient may be contained. Emollients are known to act on the skin by softening and smoothing the skin. Frequently, emollients are chosen from lipophilic compounds, such as lanolin, mineral oil and petroleum jelly, further fats and waxes.
According to the present invention the emollient is chosen from
