The present application claims the priority of Korean Patent Application No. 10-2022-0171830, filed on Dec. 9, 2022, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure is directed to an additive composition for improving bubble density and bubble elasticity, and a composition for skin cleansing.
In the case of a weakly acidic face cleanser, an amino acid-based surfactant is commonly used in consideration of harmful ingredients and irritation, but has a disadvantage in that its bubble is generally thin to lack elasticity. This is because a size of the hydrophilic group in the amino acid-based surfactant is larger compared to a soap which has dense and elastic bubble, thereby making a interfacial membrane weak and bubble quality relatively poor.
Herein, the bubble quality can be subdivided into bubble quantity, bubble density, and bubble elasticity. In previous studies, there were only cases of enriching the bubble quantity or increasing the bubble density, but there were no cases of improving the bubble elasticity. For example, even though the face cleanser is satisfactory in terms of the overall feeling of use, there are cases where satisfaction for the bubble is relatively low. This is because when the bubble elasticity is low, the overall bubble power is felt to be weak even if an amount of the bubbles is large.
Therefore, since the bubble elasticity contributes to improving the overall bubble satisfaction, it is important to improve the overall bubble satisfaction by increasing both the bubble density and bubble elasticity.
An aspect of the present disclosure is to provide an additive composition for improving bubble density and bubble elasticity of a weakly acidic skin cleanser, which can enhance not only an amount of the bubbles, but also the bubble density and the bubble elasticity.
An aspect of the present disclosure is to provide a composition for skin cleansing that can objectively quantify the bubble density and the bubble elasticity and has excellent overall bubble satisfaction.
In an aspect, the present disclosure provides an additive composition for improving the bubble density and the bubble elasticity of a weakly acidic skin cleanser, comprising a diutan gum.
In another aspect, the present disclosure provides a composition for skin cleansing, comprising the diutan gum.
In an aspect, an additive composition for improving the bubble density and the bubble elasticity of the weakly acidic skin cleanser disclosed in the present disclosure can simultaneously improve the bubble density and the bubble elasticity of the skin cleanser, thereby enhancing overall bubble satisfaction with the skin cleanser.
In another aspect, a composition for skin cleansing disclosed in the present disclosure comprises the diutan gum, thereby enabling to improve an amount of the bubbles, the bubble density and the bubble elasticity while maintaining weak acidity.
Hereinafter, the present disclosure will be described in more detail through the following Examples. However, the Examples are provided only for illustrative purposes to aid understanding of the present disclosure, and the category and scope of the present disclosure are not limited thereto.
Exemplary embodiments of the present disclosure provide an additive composition for improving bubble density and bubble elasticity of a weakly acidic skin cleanser, comprising a diutan gum.
Referring to
In an embodiment, the weakly acidic skin cleanser may be a weakly acidic amino acid-based skin cleanser.
In an embodiment, the composition of the present disclosure may further comprise an amino acid-based surfactant.
In an embodiment, the composition may further comprise a cationic polymer. According to an embodiment of the present disclosure, a repulsion force of the amino acid-based surfactant head, which is an anionic surfactant, can be reduced by using the cationic polymer to strengthen interfacial membranes and help improve a bubble power.
Conventionally, due to a slippery nature of the cationic polymer with a high degree of substitution, there was no choice but to use the cationic polymer with a low degree of substitution. In this case, there was a problem that the bubble elasticity could not be sufficiently maintained. Specifically, if the degree of substitution of the cationic polymer is high or a structure is not well packed in a straight line, the interfacial membranes widen and the bubble can be easily dissipated, whereby the conventional skin cleanser could not use a gua polymer with the high degree of substitution due to its slippery feeling of use. Therefore, a polymer is needed to act as a bridge that can hold the water layer between the interfacial membranes. According to an embodiment of the present disclosure, a diutan gum plays that role to improve both of the bubble density and the bubble elasticity.
In an embodiment, the cationic polymer may be a guar gum. Unlike the other cationic polymers that only have an effect on the bubble density, the guar gum can improve the bubble elasticity more than the other cationic polymers.
In an embodiment, the composition further comprises the cationic polymer, and a weight ratio of the cationic polymer and the diutan gum may be 1:0.5 to 2.
For example, the weight ratio of the cationic polymer and the diutan gum may be 1:0.5 or more, 1:0.6 or more, 1:0.7 or more, 1:0.8 or more, 1:0.9 or more, 1:1 or more, 1:1.1 or more, 1:1.2, or more, 1:1.3 or more, 1:1.4 or more, 1:1.5 or more, 1:1.6 or more, 1:1.7 or more, 1:1.8 or more, or 1:1.9 or more, and may be 1:2 or less, 1:1.9 or less, 1:1.8 or less, 1:1.7 or less, 1:1.6 or less, 1:1.5 or less, 1:1.4 or less, 1:1.3 or less, 1:1.2 or less, 1:1.1 or less, 1:1 or less, 1:0.9 or less, 1:0.8 or less, 1:0.7 or less, or 1:0.6 or less.
If the weight ratio of the cationic polymer and the diutan gum is less than 1:0.5, both the bubble density and/or bubble elasticity may be reduced, especially the bubble elasticity may be reduced, and if it is more than 1:2, both the bubble density and/or bubble elasticity may be reduced.
In an embodiment, the composition further comprises the cationic polymer, and a total weight of the cationic polymer and the diutan gum may be 0.05 to 1% by weight based on the total weight of the composition.
For example, the total weight of the cationic polymer and the diutan gum may be 0.05% by weight or more, 0.1% by weight or more, 0.15% by weight or more, 0.2% by weight or more, 0.25% by weight or more, 0.3% by weight or more, 0.35% by weight or more, or 0.4% by weight or more, and may be 1% by weight or less, 0.5% by weight or less, 0.45% by weight or less, 0.4% by weight or less, 0.35% by weight or less, 0.3% by weight or less, 0.25% by weight or less, 0.2% by weight or less, 0.15% by weight or less, or 0.1% by weight or less.
If the total weight of the cationic polymer and the diutan gum is less than 0.05% by weight, there is no effect on the bubble, and if it is more than 1% by weight, a formulation is not slippery and lumpy, which may provide an unpleasant touch feeling to a consumer.
In an embodiment, a pH of the composition may be 4 to 7.
For example, the pH of the composition may be 4 or higher, 4.5 or higher, 4.7 or higher, 4.9 or higher, 5.1 or higher, 5.3 or higher, 5.5 or higher, 5.7 or higher, 5.9 or higher, 6.1 or higher, or 6.3 or higher, and may be 7 or lower, 6.5 or lower, 6.3 or lower, 6.1 or lower, 5.9 or lower, 5.7 or lower, 5.5 or lower, 5.3 or lower, 5.1 or lower, 4.9 or lower, or 4.7 or lower.
The composition can maintain excellent overall bubble quality by improving not only the bubble density but also the bubble elasticity while maintaining weak acidity at the above pH.
In an embodiment, the bubble elasticity of the composition may be 11,000 cps or more as measured by a BROOKFIELD LV viscometer.
In an embodiment, the viscosity may be measured using the BROOKFIELD LV viscometer at a room temperature while rotating at 3 rpm using spindle number 3.
For example, the bubble elasticity may be 11,000 cps or more, 11,500 cps or more, 12,000 cps or more, 12,500 cps or more, 13,000 cps or more, or 13,500 cps or more.
If the bubble elasticity is less than 11,000 cps, the overall bubble satisfaction may be low even if an amount of the bubbles is large.
In an embodiment, the weakly acidic skin cleanser may be a hair cleanser, a body cleanser, a hand cleanser, or a face cleanser.

Hereinafter, the present disclosure will be described in more detail through the following Examples. However, the Examples are intended to be provided only for illustrative purposes to aid understanding of the present disclosure, and the category and scope of the present disclosure are not limited thereto.
In the following Examples and Comparative Examples, the properties of bubbles were subdivided to measure an amount of the bubbles, bubble density, and bubble elasticity.
An amount of the bubbles was determined by dropping 2 ml of a composition according to Example or Comparative Example into 50 ml of tap water, mixing the solution without separate dilution, repeating 10 times a process of mixing at 2500 rpm for 10 seconds and stopping for 3 seconds by a DFA (Dynamic Foam Analyzer, KRUSS), and then measuring a height of the bubbles (Unit: mm).
The bubble density was determined by dropping 2 ml of a composition according to Example or Comparative Example into 50 ml of tap water, mixing the solution without separate dilution, repeating 10 times a process of mixing at 2500 rpm for 10 seconds and stopping for 3 seconds by the DFA (Dynamic Foam Analyzer. KRUSS), and then measuring the number of the bubbles per unit area (number/mm).
The bubble elasticity was determined by preparing a solution containing 50 g of a composition according to Example or Comparative Example and 50 g of tap water in a 500 ml of a beaker, mixing the solution at 300 rpm for 1 minute and at 500 rpm for 2 minutes using an Azimixer (HOMO-MIXER & AGITATOR, SWI), and then measuring a viscosity of the bubbles 1 minute later (BROOKFIELD LV viscometer).
As shown in Table 1 below, a composition containing a fatty acid, a fatty alcohol, an amphoteric surfactant, and a cationic polymer in an anionic surfactant was prepared to indicate degrees of an amount of the bubbles, bubble density, and bubble elasticity according to the following standards.
As a result of the observation, it was possible to reduce repulsion force of the anionic surfactant head, but it was difficult to improve the bubble elasticity. Specifically, it was confirmed that in the formulation based on the amino acid surfactant, addition of the cationic polymer was most effective in improving the bubble power, and that addition of the polyquaternium polymer was able to increase an amount of the bubbles and the bubble density, but the bubble elasticity was no significant effect.
As shown in Table 2, Table 3, and
As a result of the observation, it was confirmed that an effect of improving the bubble density and the bubble elasticity of the diutan gum was superior to that of the other gums.
As shown in Table 4. Table 5, and
As a result of the observation, it could be confirmed that when the guar gum and the diutan gum were combined in a ratio of 1:1, the bubble density (
As a result, it could be confirmed that the natural gums alone did not have a significant effect on the bubble power, whereas when the cationic polymer was combined with the polysaccharide polymer that has a slippery feeling of use but can thicken the water phase, it was possible to increase both of the bubble density and the bubble elasticity while maintaining an amount of the bubbles.
