Abstract

The present invention relates to a cosmetic composition stably containing a substance beneficial to the skin, and more particularly, to a water-in-oil emulsion-type cosmetic composition which contains a combination of a weak acid capable of constituting an organic modified clay mineral and a buffer system, and a salt having a conjugate base of the weak acid, or a combination of a weak base and a salt having a conjugate acid of the weak base, to effectively reduce emulsification instability, which is a problem when a substance beneficial to the skin is contained in an internal phase.

Description

Cosmetic composition stably containing skin benefit substance

The present invention relates to a cosmetic composition stably containing a skin agonist in the inner phase.

Emulsions are generally divided into two types. One is an oil in water type (O / W) emulsion in which oil is dispersed in small particles with water in a continuous phase, and the other is water in which water is dispersed in a continuous phase with oil. It is an oil of water in oil type (W / O).

The water-in-oil emulsion cosmetic composition has the effect of inhibiting the evaporation of water from the skin compared to the oil-in-water emulsion cosmetic composition, cosmetics, ointments, etc. used for the purpose of skin protection and treatment, and continuously delivers moisture and skin active substances for a long time Better skin protection and treatment This is due to the fact that the continuous phase of the water-in-oil cosmetic composition is oil, which can form a strong oil film on the skin. In addition, it has excellent water resistance compared to the oil-in-water type, and its application range is wide such as a sunscreen product for protecting skin from ultraviolet rays and diaper cream for preventing diaper rash of infants.

In general, emulsions form a thermodynamically unstable system, and the resulting system does not last forever and is separated into two phases: an oil phase and an aqueous phase. Therefore, products using emulsions such as cosmetics, medicines, and foods must maintain a stable product state at least during the distribution and use periods. However, water-in-oil type emulsions are difficult to maintain emulsification stability due to less suitable stabilizer than oil-in-water type emulsions, and thus stability problems have been raised.

In order to solve this stability problem, a method of improving stability by conventionally increasing the viscosity of the water-in-oil type emulsion or reducing the content of the aqueous phase dispersed in the oil phase has been used. However, when the agonist of the inner phase is a substance that forms a large amount of salt or lowers the pH to make the emulsion system unstable, the above method did not show a great effect.

Substances that can be beneficial to the skin must maintain their potency until applied to the skin. In addition, due to the nature of cosmetics, the potency of the active substance must be maintained even within the expiration date. Among the many skin-effect substances known to date, many of them are difficult to maintain in the formulations of cosmetics, foods, etc. due to their properties. For example, vitamin C, which is known to be a very effective whitening agonist, is rapidly oxidized and denatured when dissolved in an aqueous phase, resulting in poor efficacy or activity. It is also difficult to stabilize the formulation by dropping the pH and, by dissolving the hydrogen ions formed upon dissolution, to break down the viscosity-forming system commonly used in common oil-in-water emulsions, resulting in poor formulation stability. In addition, due to the presence of a potent substance on the trauma, it is easily exposed to water, air, and light to further promote denaturation. However, when the skin agonist is applied to the water-in-oil formulation, it is no longer necessary to consider the problem of formulation stability that may occur in the above oil-in-water formulation. In addition, it is possible to carry a skin-effect material applicable to the water phase to effectively formulate an active ingredient that can be easily deteriorated by light, moisture, or air.

However, even if you have a skin agonist loaded on the inner surface to take advantage of the water-in-oil formulation, if the emulsification stability is lowered, the benefits can be offset as the agonist loaded on the inner phase out.

Accordingly, the present inventors prepared a water-in-oil cosmetic composition using an organic modified clay mineral and a buffer solution together with the oil used in the conventional water-in-oil emulsion cosmetic composition and an emulsifier of HLB 7 or less, when a large amount of hydrogen ions when dissolved in the water phase Alternatively, the present invention has been completed by discovering that the emulsified state can be stabilized even when the salt-releasing skin agonist is supported on the inner phase.

Therefore, an object of the present invention is to effectively improve the emulsification instability which is a disadvantage of the water-in-oil emulsion cosmetic composition including a skin-effect material.

In order to achieve the above object, the present invention provides a cosmetic composition comprising an organic modified clay mineral and a buffer solution.

The water-in-oil type emulsion cosmetic composition of the present invention shows a good emulsification state while supporting the skin agonist on the inner phase, there is no change in the titer of the skin agonist over temperature or time, and has excellent stability and good use feeling.

Figure 1 shows the results of the vitamin C titer content test of Example 1 and Comparative Examples 1 to 4, it is a measure of the residual ratio of cosmetics in vitamin C over time.

A modified clay mineral, (b) a buffer solution, (c) an oil and (d) an emulsifier with an HLB of 7 or less.

In the cosmetic composition of the present invention, the first component included as an active ingredient is (a) an organic modified clay mineral. By mix | blending an organic modified clay mineral with a cosmetic composition, the coalescence between aqueous phase particles is prevented and the high temperature stability of an emulsion improves. Generally, as long as it can be used in cosmetics, etc., it can be used arbitrarily without a restriction | limiting. Preferred organic modified clay minerals for use in the cosmetic composition of the present invention are cationic modified clay minerals obtained by treating water-expandable clay minerals with quaternary ammonium salt type cationic surfactants.

As for the compounding quantity of (a) component, 0.1-20 weight% is preferable with respect to the composition total weight, More preferably, it is 0.1-10 weight%. It is difficult to obtain sufficient stability at less than 0.1% by weight, and sufficient stability can be obtained at a compounding amount of up to 20% by weight, but it is not preferable if the amount is blended at more than 20% by weight, because the formulation hardens and the stability also decreases. The component (a) may be used alone or in combination of two or more, which is included in the oil phase in the cosmetic composition.

In the cosmetic composition of the present invention, the second component included as an active ingredient is (b) a buffer solution. (b) The component is composed of a substance for adjusting the pH of the water phase in the water-in-oil formulation, a combination of a weak acid and a salt having a base salt of the weak acid or a salt having a base salt of the weak base and a weak base which may constitute a buffer system. It is not particularly limited as long as it is composed and can be generally used in cosmetics. For example, a combination of carbonic acid and sodium bicarbonate, a combination of phosphoric acid and potassium phosphate, a combination of citric acid and sodium citrate, and the like can be optionally used. It can be adjusted arbitrarily according to the pH range, so that the modification of the agonist to be used can be slowed down as much as possible and the stability is maintained, and the blending amount can also be arbitrarily adjusted.

As for the compounding quantity of (b) component, 0.01-5 weight% is preferable in the water-in-oil type emulsion cosmetic whole quantity, More preferably, it is 0.01-3 weight%. If the amount is too small, a stable buffering action cannot be expected because the absolute number of ions constituting the buffer solution is insufficient to exhibit a common ion effect. If the amount is too large, the amount of ions present in the entire aqueous phase increases, and thus formulation stability. Can drop. The component (b) may be used alone or in combination of two or more, which is included in the aqueous phase in the cosmetic composition.

In the cosmetic composition of the present invention, the third component contained in the active ingredient is (c) oil. The oil component (c) is a substance that forms the outer appearance of the water-in-oil formulation, and is not particularly limited as long as it can be generally used in cosmetics and the like. For example, liquid fats, solid fats, waxes, hydrocarbon oils, higher fatty acids, higher alcohols, synthetic ester oils, silicone oils and the like can be optionally used.

As for the compounding quantity of (c) component, 10-70 weight% is preferable with respect to the composition total weight. When the content of the oil exceeds 70% by weight, it is not preferable because the formulation stability and the feeling of use decrease. It is included in the oil phase in the cosmetic composition.

In the cosmetic composition of the present invention, the fourth component included as an active ingredient is (d) an emulsifier. The emulsifier as the component (d) uses one having a HLB of 7 or less. This is because it is difficult to obtain a stable water-in-oil emulsion composition using such an emulsifier because an emulsifier having an HLB of more than 7 has high hydrophilicity. Preferred lipophilic emulsifiers are not particularly limited to various emulsifiers in which an alkyl group containing a hydrophilic group and a lipophilic group is added to one main chain.

Emulsifiers of HLB 7 or less include sorbitan fatty acid esters such as sorbitan monolaurate, sorbitan monoisostearate, and sorbitan tristearate; Glycerin fatty acid esters such as glycerol monostearate and glycerol monooleate; Polyoxyethylene hardened castor oil; Dimethicone copolyols and cetyl dimethicone copolyols which are polyether modified silicone type surfactants; Polyethyleneglycol-9 polydimethylsiloxyethyldimethicone which is a silicone type surfactant, polyethyleneglycol-7 dimethicone, etc. are mentioned.

As for the compounding quantity of (d) component, 0.01-10 weight% is preferable with respect to the composition total weight, More preferably, it is 0.1-5 weight%. If the amount of the component is too small, a stable emulsion cannot be obtained. If the amount of the component is too large, it is sticky and there is a problem of feeling of stiff feeling. (d) The component can be used arbitrarily selecting 1 type, or 2 or more types, and it is contained in an oil phase in a cosmetic composition.

In addition, the component (d) may be included in the composition of the present invention in the state of being adsorbed to the organic modified clay mineral which is the component (a). That is, it is also possible to mix | blend an organic modified clay mineral with the surfactant of HLB7 or less which is an emulsifier which can be used by this invention, and to mix | blend the emulsifier of HLB7 or less to the organic modified clay mineral in the state adsorbed.

In addition to the above essential components, the external wound may optionally contain additional components within a range that does not impair the effects of the present invention. For example, other oily components, oil-soluble polymers, powders, polymer granules, etc. can be mix | blended as a component normally used for cosmetics, a quasi drug, etc.

In addition, the cosmetic composition of the present invention is appropriately selected by the components contained in the conventional emulsified cosmetic composition, that is, moisturizing components such as antioxidants, polyhydric alcohols and hyaluronic acid, various vitamins, preservatives, colorants, fragrances and sunscreen ingredients, etc. Can be added.
