Description

Technical Field

[0001] The present invention relates to a composition suitable for cosmetic use, particularly suitable for hair styling or skin care purposes, comprising at least two of the components konjac gum, xanthan gum, and algin, wherein the weight ratio of these components is within a specific range. Furthermore, the present invention relates to a raw material composition consisting of at least two of the above components, which can be used in the production of the composition according to the present invention. Furthermore, the present invention relates to the use of a composition for hair styling or skin care.

Background Art

[0002] Konjac gum and glucomannan are used synonymously herein and are both abbreviated as Glu or K. Algin is abbreviated as Alg or A, and xanthan gum is abbreviated as Xan or X.

[0003] In the cosmetics industry, the importance of sustainability and natural aspects is increasing. A major factor influencing this is the discussion regarding microplastics. Therefore, the demand for providing sustainable products has become a major market requirement. This has led to problems in cosmetic formulations where polymers play an important role in either the thickening and stability or texture of the formulation.

[0004] Synthetic polymers are widely used in cosmetic formulations for these aspects. The texture of synthetic polymers is well-known and preferred by consumers. Natural biopolymers obtained from plants can be alternatives to these synthetic polymers. Although these polymers have the advantage of being natural products, they are accompanied by drawbacks regarding compatibility. One of the main drawbacks recognized by consumers is the texture of the product, which is often either thin or watery.

[0005] It is necessary to overcome the problems in the blending of biopolymers. It is necessary to achieve an attractive, soft, and pleasant texture without compromising other goals regarding performance parameters.

[0006] Publications posted online on the IP.com platform with IP.com number IPCOM000268678D disclose hair mousses containing natural polymers. Formulations containing xanthan gum and algin are disclosed.

Example

[0022] In this experimental section and all other parts of this specification, unless otherwise specified, % means % by weight.

[0023] A ternary system composed of a combination of three different bio-based polymers was examined to determine the range of ternary systems having advantageous properties for cosmetic use, particularly for hair styling use.

[0024] The following ternary systems were examined. · Konjac gum, xanthan gum and algin

[0025] The following commercially available products obtainable from BASF SE in Germany were used. The following abbreviations are used in this specification. · Konjac gum (Glu) Verdessence® Glucomannan · Xanthan gum (Xan) Verdesssence® Xanthan · Algin (Alg) Verdessence® Alginate

[0026] The following properties of this ternary system were investigated. · Texture · Bending rigidity · Flaking property (including the number of flakes, particle size and area ratio) · Curl retention

[0027] As a result of examining these four properties, six parameters were determined: three parameters (number of flakes, particle size, and area ratio) that characterize flaking property, one parameter that characterizes texture, one parameter that characterizes bending stiffness, and one parameter that characterizes curl retention.

[0028] The experimental design (DoE) method was used to examine the properties of the ternary system, which will be described in more detail in the following paragraphs.

[0029] The experimental design method (DoE) was used to conduct experiments on mixtures of three polymers A, B, and C. DoE was implemented using Minitab® 20.3, software available from Minitab Inc. To create the experimental map, a matrix based on the simplex method for 2 - 10 components was selected. The measurement points of the matrix based on the simplex method are evenly arranged within a triangular chart, and the measurement point with equal amounts of each polymer is placed at the center of the chart. In this case, there were three components, which were the three polymers of the polymer ternary mixture.

[0030] The experimental map placed within the triangular chart included 19 measurement points where each mixture contained different amounts of each polymer. In Minitab® 20.3, inputs at these 19 measurement points were required. These 19 measurement points were placed at the following positions within the triangular chart: · Three measurement points were placed at the corners of the triangular chart (representing pure polymers). · Nine measurement points were placed on the sides of the triangular chart. Therefore, these represent mixtures of two polymers. · One measurement point was placed at the center of the triangular chart representing a mixture of three polymers where the amounts of all three polymers were equal. · Six measurement points were placed symmetrically with respect to this central point.

[0031] This experimental plan was randomly given to the experimenter without repetition.

[0032] After the experiment was completed (i.e., after the investigation of the four characteristics to be investigated for each of the 19 measurement points) and the corresponding results were obtained, Minitab® 20.3 was used again to fit the experimental data to the optimal mathematical model available for each of the six parameters. For each parameter, a mathematical model that best represents the results was selected from those listed below. · Linear model: characteristic = c1 * A + c2 * B + c3 * C · Quadratic model: characteristic = c4(A * B) + c5(A * C) + c6(B * C) · Special cubic model: characteristic = c7(A * B * C) · Full cubic model: characteristic = c8[A * B(A - B)] + c9[A * C(A - C)] + c 10 [B * C(B - C)] · Special quartic model: characteristic = c 11 (A * A * B * C) + c 12 (A * B * B * C) + c 13 (A * B * C * C) · Full quartic model: characteristic = c 14 (A * B * (A - B) 2 ) + c 15 (A * C * (A - C) 2 ) + c 16 (B * C * (B - C) 2 ) (The coefficients c1, c2,... c 16is obtained by data modeling; if the coefficient is zero, this term does not apply).

[0033] Users of Minitab (registered trademark) 20.3 were also able to select combinations from among these various models. In order to select the optimal mathematical model for each characteristic of each ternary system, the p-value of each model was set not to exceed 0.05. Furthermore, the R 2 value was set to not exceed 65%.

[0034] The meaning of the p-value is well known in the art. The p-value is used to determine whether a pattern of measurement results is statistically significant. If the p-value is 0.05 or less, the result is said to be significant. If the p-value exceeds 0.05, the model is not statistically significant, and thus the result will be overfitted. In that case, the coefficients (c1, c2,... c 16 ) of that specific model are set to zero.

[0035] R 2 The meaning of the value is well known in the art. The R 2 value is a statistical indicator of goodness of fit that indicates to what extent the independent variable in a regression model explains the variation of the dependent variable. R 2 If it is 100%, the experimental data and the mathematical model completely match, but this is impossible. Based on the inventors' experience, if this value is 65% or more, it becomes a reliable model.

[0036] If that (the p-value is 0.05 or less and the R 2 value exceeds 65%) does not hold, two or three models were compared with each other, and a more appropriate model was determined by comparing the PRESS value and the R 2 (predicted) value.

[0037] PRESS is a parameter well-known in the art and means "predicted residual sum of squares". To demonstrate the fitness of the model, observation samples not used for the estimation of the model were used. The smaller this value is, the better the prediction ability of the mathematical model.

[0038] R 2 R (prediction) is a parameter well-known in the art. 2 When calculating R (prediction), each measurement point is systematically removed from the dataset to estimate the regression equation and determine how well the model predicts the removed measurement points. If the model is overfitting, R 2 (prediction) will be lower.

[0039] By conducting the described DoE experiments and model creation, it is possible to determine in which regions of the triangular diagram (diagram) representing the composition of the ternary polymer system investigated, the six characteristics studied exceed (or fall below) the selected threshold values.

[0040] To find the optimal regions within the diagram corresponding to the best mixtures, minimum requirements were set for each characteristic. These minimum requirements were set considering commercially available standard hair polymers.

[0041] Regarding the texture characteristic, it is currently targeted to be more perceptually acceptable than the current biopolymer for a reference commercially available hair gel, which is xanthan gum.

[0042] Regarding the characteristics of bending rigidity and curl retention, minimum and maximum values were set considering various commercially available synthetic polymers that impart different bending rigidities, such as PVP, VP / VA copolymer, and VP / methacrylamide / vinylimidazole copolymer. The goal was to approach or further improve as closely as possible to the standard of this composition, that is, to make it as high as possible.

[0043] Regarding the flaking property, the minimum and maximum values were set considering various commercially available synthetic polymers that impart various flaking values, such as PVP, VP / VA copolymers, and VP / methacrylamide / vinylimidazole copolymers. The goal was to get as close as possible or even better to the standard of this composition, that is, to make it as low as possible.

[0044] In the triangular diagram (diagram), the optimal region representing the optimal mixture for hair styling / gel formulations is defined as the overlapping part of the minimum requirements of all four properties in these diagrams.

[0045] In the following paragraphs, the methods for determining texture, bending rigidity, flaking property, and curl retention will be described in detail.

[0046] Texture A sensory evaluation was conducted to evaluate the soft and creamy texture of the sample to be evaluated. The evaluation was carried out by three trained volunteers. The results were calculated as the median of the three evaluations.

[0047] The goal was to make it different from the watery and thin texture of common natural solutions in the prior art, which is not strongly preferred by consumers. The texture was evaluated in 0.5-step increments from grade 1 to grade 4 (grade 1 was the highest grade and 4 was the lowest grade). The texture of xanthan gum as a standard was set to 3 as a reference value. The texture of alginate as a standard was set to 1.5 as a reference value.

[0048] Bending Rigidity Test Flat-shaped white ethnic dark brown hair bundles with a weight of 1.8 g, a width of 2 cm, a length of 8 cm, and a free end, with a 2 cm × 2 cm length adhered to a soft cloth piece, were used. As samples, seven clean and dry hair bundles were used each.

[0049] For use in the test, the hair gel was diluted with deionized water at a ratio of 1:4. An amount of 1.4 g per bundle was applied. This hair bundle was combed with the fine side of the comb until it became homogeneous. The separated parts were gathered by pinching with two fingers without pressing. The hair bundle was processed with a special groove type to create a flat and uniform shape.

[0050] Next, the formed hair bundle was vertically suspended on a rack, and the hair bundle was dried for at least 1 hour under normal laboratory conditions. After drying, this rack and the hair bundle were placed in an artificial weather chamber at a relative humidity of 65% and 21°C overnight.

[0051] Next, the maximum load in cN units required to break the hair bundle was measured using an apparatus such as a texture analyzer equipped with a three-point bending stiffness test mechanism that can measure the force required up to the breaking point, for example, Diastron. The processed hair bundle was bent up to the breaking point by a probe connected to a force measurement cell. This measurement was repeated with 7 hair bundles, and the average value of the maximum force before breaking was obtained. The bending stiffness value is given in cN units as the maximum force.

[0052] Flaking property After measuring the bending stiffness, the dried hair bundle was flaked by combing it with a comb using a material testing machine (supplier: Zwick / Z005). An image of the hair bundle was taken using a circular light and a polarizing filter in an imaging box to adjust the lighting conditions and avoid reflection. The photograph was evaluated with a software package (open platform: ImageJ) to determine the number of flakes on the hair bundle and the average particle size of the flakes. The area ratio was calculated from the number of flakes, the average particle size of the flakes, and the surface area of the hair bundle.

[0053] The strength of the flaking property was determined using the following three parameters: the number of flakes, the particle size of the flakes, and the area ratio representing the area covered by the particles. The lower the value of any of the three parameters, the lower the flaking property.

[0054] Curling retention A 2 g dark brown hair bundle with a free end of 15 cm in length and a circular shape was used. The hair bundle was used after being bleached with 5% hydrogen peroxide. The gel was diluted with deionized water at a ratio of 1:2. An amount of 1.5 g per bundle was applied. Five bundles of this hair were combed evenly on the fine side of the comb teeth until homogeneous. The separated parts were gathered together by pinching with two fingers without pressing.

[0055] The hair bundle was wrapped around a Teflon curler with a guide to ensure that the entire bundle was curled evenly. Then the hair bundle was dried overnight at 40 °C together with the curler and then allowed to cool for 1 hour. It was hung on a rack with graduations in an artificial weather chamber at 25 °C and 90% rh, and accordingly, the initial length of the hair bundle and the lengths after 5 hours and 24 hours were recorded.

[0056] The curl retention (CR) was calculated using the following formula: CR (%) = [(L - Lt) / (L - L0)] × 100 (where L = the length of the hair (15 cm) L0 = the length of the curled hair at the start Lt = the length of the curled hair after a given period (5 hours / 24 hours)) was used for the calculation.

[0057] Using formulations containing a ternary system, the texture, bending rigidity, flaking property, and curl retention of this ternary system were investigated. Initial tests were conducted to determine the total polymer content in the formulations from which useful hair styling preparations could be obtained. This was carried out based on a series of concentrations from 0.5% to 5%. In this configuration, the synthetic polymer concentrations in commonly used formulations were considered. Surprisingly, it was found that the target texture and performance could be obtained at a concentration half that of the commonly used concentration of synthetic polymers.

[0058] The following formulations were used for the DoE measurements described.

[0062] The four characteristics described above were determined by 19 points of each system described in the above table. As described above, based on these 19 points, a mathematical model regarding these four characteristics was constructed.

[0063] As described above, the optimal region within the triangular diagram (diagram) representing the ternary system under consideration is defined by overlaying the minimum requirements of all four characteristics within this diagram.

[0064]

Table 3

[0065] It was possible to achieve a texture score higher than the texture score achieved only with xanthan gum (set to 3.0 as a standard), and at the same time, it was possible to achieve high curl retention (CR), high bending stiffness (BS), and low flaking property. It was possible to achieve a texture score of 1.75 or less.
