[0002] Thickening of cleaning preparations containing opacifying agents

[0003] The present invention relates to cosmetic cleansing preparations containing benzyl acetate (INCI: Benzyl Acetate) and / or dimethylbenzylcarbinyl acetate (INCI: Dimethyl Phenethyl Acetate).

[0004] A person's outward appearance can be influenced and enhanced through the use of cosmetic products. Regular use of cleansing and care products ensures that people feel attractive, beautiful, and comfortable in their surroundings, and radiate this outwards.

[0005] The cleansing process serves the purpose of loosening and rinsing away dirt such as sweat residue or accumulated skin cells. For this purpose, shower gels and cleansing products typically contain anionic, non-ionic, or amphoteric surfactants. Surfactants enable, among other things, the dissolution of organic, particularly nonpolar, substances in water. Since, in addition to removing external dirt particles from the skin, they can also dissolve the skin's own particles, leading to dry skin or skin irritation. Therefore, it is important that a shower gel also cares for the skin. This can be achieved by using mild cleansing products and adding agents to replenish the skin's natural oils or moisturize it.

[0006] For a consumer to use a cleansing preparation as a shower gel, the water-based mixture must be thickened. Thickening a cleansing preparation results in a gel-like consistency with a characteristic viscosity. A product's viscosity influences its ability to be spread and lathered. Viscosity also affects product dispensing and dosage. If a shower gel has too low a viscosity, it is difficult to apply evenly, whereas too high a viscosity makes it harder to spread. One way to thicken a cleansing preparation is by increasing the surfactant content. However, this should be avoided, as it reduces the gentleness of the cleansing preparation, which can lead to skin irritation or dryness.Consequently, shower gels are formulated with thickening agents that can bind unbound water and thus increase viscosity. Macromolecules such as polysaccharides, silicones, or acrylate-containing polymers are often used as thickening agents to adjust viscosity.

[0007] For environmental reasons, there is a growing effort to avoid using homo- or copolymers of acrylic acid in cleaning products. The biodegradability of these substances is not sufficiently established, and consumers desire products free of homo- or copolymers of acrylic acid or their derivatives. Consequently, salt thickeners are increasingly being used, and there is a fundamental need for additional thickening options for shower gels. This is because, in cleaning products containing anionic surfactants, an excessively high salt content, particularly sodium chloride, can lead to a loss of viscosity.

[0008] The viscosity of a shower gel can be determined by measuring it with a Rheomat (model R 123 from proRheo). The measuring element used in the device measures the viscosity of a specific quantity of the cleansing preparation. A cleansing preparation exhibits increased viscosity if it exceeds 3000 mPa*s. This ensures that the cleansing preparation spreads easily on the skin and can be easily dispensed from its packaging.

[0009] Besides the feel of a cleansing product, its appearance also plays a significant role for consumers. Cleansing products with a light color are particularly appealing to consumers, as this color is associated with purity and cleanliness. For this reason, cleansing products are often manufactured in white or opaque form, as this also creates the impression that the cleansing product is particularly creamy and nourishing for the skin. Opaque cleansing products, in particular, are not transparent to the consumer and have a milky texture, which conveys a luxurious impression. To give a cleansing product this appearance, opacifiers are used. These substances are present as crystalline platelets or rods and reflect and scatter incident light, resulting in the cleansing product appearing cloudy.To achieve a uniform opacity in the shower gel, the opacifier in the cleansing preparation must be stabilized. Therefore, there is a particular need for thickening agents in cosmetic cleansing preparations that also stabilize the opacifiers used. Consequently, the object of the present invention was to provide cosmetic cleansing preparations containing anionic surfactants and at least one opacifying agent, and exhibiting increased viscosity without the use of acrylate-containing homopolymers or copolymers.

[0010] Conventional cosmetic cleansing preparations are known, among others, from EP1647591 A1 or EP2768474 A2. These cleansing preparations typically contain anionic and amphoteric surfactants. However, the disclosed preparations did not provide any indication of the present invention.

[0011] Surprisingly for those skilled in the art, it has now been found that the problem of increasing the viscosity of a cosmetic cleaning preparation containing opacifiers could be solved by the present invention without the use of homo- or copolymers of acrylic acid.

[0012] The present invention relates to a cosmetic cleansing preparation comprising, based on the total weight of the cleansing preparation, a) at least one anionic surfactant; b) glycol distearate; c) at least one substance selected from the group consisting of benzyl acetate and / or dimethyl phenethyl acetate, characterized in that it does not contain any homo- or copolymers of acrylic acid.

[0013] Another object of the invention is the use of a combination of at least one anionic surfactant, glycol distearate and at least one substance selected from the group consisting of benzyl acetate and / or dimethyl phenethyl acetate to increase the viscosity of a cosmetic cleansing preparation.

[0014] Surprisingly, the combination of the invention, or rather the cleaning preparation according to the invention, showed a significant increase in viscosity. As the comparative tests demonstrate, a surprising synergy appears to occur between the components according to the invention. It was found that the simple use of the components resulted in a less viscous cleaning preparation, while the combinations surprisingly increased the viscosity. Consequently, the viscosity of the cleaning preparations could be increased without using acrylate-containing homo- or copolymers or increasing the surfactant content. Where viscosity values ​​are given in this disclosure, all values ​​refer to a measurement at 25°C in a 150 ml wide-mouth bottle (VWR No.: 807-001) using the Rheomat R 123 from proRheo GmbH. The Rheomat R 123 from proRheo GmbH is a rotational viscometer, i.e.,A measuring element rotates within the substance being measured in a stationary measuring container. The force required to rotate the measuring element at a predetermined speed within the sample is measured. The viscosity is calculated from this torque, the rotational speed of the measuring element, and the geometric dimensions of the measuring system. The measuring element used is No. 1 (article no. 200 0191), suitable for a viscosity range up to 10,000 mPa s, with a rotational speed range of 62.5 rpm. -1 , used. Viscosity was always measured 24 hours after preparation.

[0015] Where weight percentages (wt%) are given below without reference to a specific composition or mixture, these percentages always refer to the total weight of the cosmetic cleansing preparation. Where ratios of components / substances / groups of substances are disclosed below, these ratios refer to the weight ratios of the components / substances / groups of substances mentioned.

[0016] The terms “according to the invention”, “advantageous according to the invention”, “advantageous in the sense of the present invention”, etc., always refer within the scope of the present disclosure to the preparation according to the invention, the use according to the invention and the method according to the invention.

[0017] Unless otherwise stated, all tests were conducted under standard conditions. "Standard conditions" means 20°C, 1013 hPa, and a relative humidity of 50%.

From the above group, Cocamidopropyl Betaine is selected as the most preferred amphoteric and / or zwitterionic surfactant.

[0052] Advantageously, the proportion of amphoteric and / or zwitterionic surfactants, in particular the amphoteric and / or zwitterionic surfactants previously listed as particularly advantageous, in the cosmetic cleaning preparation according to the invention is 0.5 to 5.0 wt.%, preferably 1.0 wt.% to 4.5 wt.% and particularly preferably 2.0 wt.% to 4.0 wt.%, based on the total weight of the cleaning preparation.

Within these embodiments, it is further particularly preferred if no other amphoteric and / or zwitterionic surfactants are included besides cocamidopropyl betaine.

[0054] According to the invention, the cleaning preparation advantageously comprises dimethylbenzylcarbinyl acetate (INCI: Dimethyl Phenethyl Acetate). If dimethylbenzylcarbinyl acetate (INCI: Dimethyl Phenethyl Acetate) is included, it is advantageous if the proportion of dimethylbenzylcarbinyl acetate (INCI: Dimethyl Phenethyl Acetate) is from 0.0001 wt.% to 3.0 wt.%, preferably from 0.01 wt.% to 2.0 wt.%, and particularly preferably from 0.1 wt.% to 1.1 wt.% based on the total weight of the preparation.

It is also advantageous within the meaning of the present invention if the preparation is free of silicone oils.

[0060] The cosmetic cleansing preparations in question can be preserved using preservatives commonly employed in cosmetics. These include, for example, parabens such as methylparaben, propylparaben, ethylparaben, and butylparaben. However, the use of acid-based preservatives commonly used in the food industry is also advantageous. These include, for example, benzoic acid and / or salicylic acid and / or their salts. The inclusion of sodium benzoate is particularly preferred, with the proportion of sodium benzoate preferably being in the range of 0.2 to 0.65 wt.%, more preferably 0.3 to 0.55 wt.%, and most preferably 0.4 to 0.5 wt.% based on the total weight of the preparation.

[0062] The cosmetic cleansing preparation according to the invention is characterized in that it contains at least one opacifier selected from the group consisting of glycol distearate, glyceryl stearate, and / or PEG-3 distearate. Opacifiers are water-insoluble, mostly microparticulate substances that are suspended in the air and reflect light particularly well, giving the cleansing preparation a milky or cloudy appearance. Glycol distearate is selected as the preferred opacifier from the aforementioned group. If glycol distearate is included, it is advantageous if the total proportion of glycol distearate is from 0.1% to 1.0% by weight, preferably from 0.3% to 0.8% by weight, and particularly preferably from 0.5% to 0.7% by weight, based on the total weight of the preparation.

[0063] Furthermore, the cleaning preparations according to the invention may contain further substances selected from the group consisting of glycerin, benzoic acid and sodium hydroxide.

[0064] If glycerin is included, it is advantageous if the total glycerin content is 0.01 to 1.0 wt.%, preferably 0.05 to 0.5 wt.%, and particularly preferably 0.07 to 0.1 wt.%, based on the total weight of the preparation. The cleaning preparation of the invention is advantageously characterized in that it has a viscosity of less than 10,000 mPa s under normal conditions, more preferably less than 8,000 mPa s, more preferably less than 6,000 mPa s, and particularly preferably less than 5,000 mPa s. Furthermore, it is advantageous if the cosmetic preparation has a viscosity of at least 2,000 mPa s, more preferably at least 3,000 mPa s, more preferably at least 3,500 mPa s, and particularly preferably at least 4,000 mPa s.Accordingly, the viscosity of the cosmetic preparation is advantageously 2000 to 10000 mPa s, preferably 3000 to 8000 mPa s, more preferably 3500 to 6000 mPa s and particularly preferably 4000 mPa s to 5000 mPa s.

[0065] It was surprisingly found that the invention yields preparations that exhibit an increase in viscosity, as described above. The use of the cleaning preparation according to the invention can improve the appearance and feel of a cleaning preparation for the consumer.

[0066] Comparative experiments and examples

[0067] The following examples are intended to illustrate the present invention without limiting it. Unless otherwise stated, all quantities, proportions, and percentages are based on the weight and total quantity or total weight of the preparations.

[0068] The following formulations were prepared for the comparative tests. Formulations Cf. 1 to Cf. 5 are not according to the invention, while Ex. 1 to Ex. 2 are according to the invention.

[0069]

[0070] The cleaning preparations listed above were produced and their properties were investigated in a comparative test. The viscosity of the cleaning preparations was measured 24 hours after their production.

[0071] The viscosity measurements show that the use of a combination of glycol distearate and benzyl acetate and / or dimethyl phenethyl acetate (Examples 1 and 2) leads to a surprising increase in the thickening of the respective cleaning preparation. If a cleaning preparation contains neither glycol distearate nor benzyl acetate and / or dimethyl phenethyl acetate (see 1), only a slight increase in thickening is observed. For the comparison preparations containing either glycol distearate or a compound from the group consisting of benzyl acetate and / or dimethyl phenethyl acetate (see 2 to 4), only a slight increase in thickening can be observed. Surprisingly, comparison preparations containing glycol distearate and α-phellandrene (see 5) do not show the thickening effect of the cleaning preparation.

[0072] The following examples are intended to further illustrate the invention:
