DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high water-in-oil type water-in-oil type emulsified cosmetic which is excellent in usability and stability, especially excellent in phase inversion. More specifically, it is excellent in usability, that is, when applied to hair or skin, it instantly reverses its phase, has an excellent feeling of overflowing water, and gives moisture to hair or skin,
Moisture-free, non-sticky, and stable, that is, excellent in stability over time, and also excellent in stability against physical stimuli, the content of the aqueous phase component is 50.0% by weight.
The present invention relates to the high internal water phase water-in-oil emulsion cosmetic composition described above.

[0002]

2. Description of the Related Art An emulsifier is generally used to form a water-in-oil (W / O) emulsified cosmetic in which water is dispersed in oil of a continuous phase. Conventionally, polyhydric alcohol fatty acid ester-based activators such as glycerin fatty acid ester and sorbitan fatty acid ester or polyoxyalkylene-modified organosiloxane-based activators have been generally used.

[0003] However, generally 50% of water is present in the composition.
In a high internal water phase type W / O emulsion containing at least 10% by weight, the oil phase, which is a continuous phase, tends to separate at low temperatures due to the aggregation of water droplets, and conversely, at high temperatures, the totality of water droplets increases. First, the particles are increased and settle, and oil phase separation in which the upper layer contains only oil tends to occur. Therefore, although it has already been proposed to increase the viscosity by blending a large amount of wax in order to improve such instability due to temperature, it is not perfect in terms of stability at high temperatures. Was inadequate. Further, the W / O emulsion has advantages such as protection of the skin and imparting flexibility since the external phase is oily, but it has poor usability such as stickiness, elongation and hardness during use. There was a problem.

[0004] In order to improve such usability and stability problems, when applied to the skin or hair with a high internal aqueous phase ratio, the emulsified particles are instantaneously broken at the same time as the application, and the internal phase water is removed. It is required that the surfactant overflows and has good stability over time. However, in the case of polyhydric alcohol fatty acid ester-based activators and polyoxyalkylene-modified organopolysiloxane-based activators which have been conventionally used as W / O type emulsifiers, high Although it is possible to prepare an internal aqueous phase type W / O-type emulsified cosmetic, at present it is not possible to solve the problem of stability over time.

[0005] Under such circumstances, the crosslinked polyether-modified silicone of the structural formula (I) used in the present invention has recently been developed into a paste-like polyether-modified silicone composition treated with a silicone oil under a shearing force. Techniques for developing a water-in-oil emulsion composition which has been developed and which is excellent in stability over time and feeling in use using the composition have already been proposed. Further, for the water-in-oil emulsion composition,
In order to further improve the usability, a composition containing a large amount of water has been proposed. At that time, it has already been proposed to incorporate silicic anhydride or hydrophobic silica so as not to impair the stability over time ( JP-A-6-40847).

This water-in-oil emulsion composition has the above-mentioned properties, ie, the above-mentioned usability and stability, and the stability at the time of pipe transfer required for continuous production or the like, or the repeated use. It is desirable to have stability over time, but if a physical stimulus such as a vibration test or tube fir test is used to confirm this, the emulsification will be broken even by the composition manufactured by these proposed methods. However, there is a drawback that an aqueous phase component of the internal phase comes out.

[0007]

The present inventor has also conducted research and development of a high internal water phase water-in-oil type emulsified cosmetic, and under such circumstances, the above-mentioned crosslinked polyether-modified silicone or Focusing on the properties of the paste-like polyether-modified silicone composition, they are used for excellent usability, that is, when applied to hair or skin, they instantaneously phase-change and have an excellent feeling of overflowing water and are stable The production of a high water-in-oil type water-in-oil emulsified cosmetic having excellent stability, especially stability over time, and stability against physical stimuli such as a tube rub test was attempted.

As a result, by blending the above-mentioned crosslinked polyether-modified silicone or paste-like polyether-modified silicone composition and blending the above-mentioned specific polyether-modified silicone, when applied to hair or skin, High inland water that instantaneously changes phase, exudes a feeling of water overflow, moisturizes hair or skin, is moist and non-sticky, and has excellent stability over time and stability against physical stimuli. It has been found that a water-in-oil type emulsion cosmetic can be produced, and the present invention has been completed.

Therefore, the present invention is excellent in usability, that is, when applied to hair or skin, it instantly reverses its phase, has an excellent feeling of overflowing water, moisturizes hair or skin, moisturizes, To provide a high-in-water-in-oil type oil-in-water type emulsified cosmetic which is free of stickiness, has excellent stability over time, and is particularly excellent in stability when a physical stimulus such as a tube rub test is applied. It is the purpose.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the high internal water phase water-in-oil type emulsified cosmetic of the present invention will be specifically described. However, the present invention is not limited thereto, and Of course, it is understood by the range of. The high internal water phase water-in-oil emulsified cosmetic of the present invention is such that the content of the water phase component is 50.0% by weight or more of all components, and the water phase component is dispersed in the oil phase component of the continuous phase. Water-in-oil type (W / O type) emulsified cosmetic.

Specific forms (formulations) of the cosmetic include, for example, milky lotions, skin creams, hair creams, liquid foundations, eyeliners, mascaras, eye shadows, and other milky or creamy products. The cosmetic of the present invention is not limited to those exemplified above, but falls under the cosmetic of the present invention as long as it is the above-mentioned water-in-oil emulsion cosmetic.

The cross-linked polyether-modified silicone used in the present invention is a polymer obtained by cross-linking methyl hydrogen polysiloxane with diallyl polyether at both ends, and its production is described in, for example, JP-A-4-272932 or The method can be carried out according to the method described in, for example, Japanese Unexamined Patent Publication No. 5-140320. In the present invention, a product produced thereby can be used, or a commercially available product may be used.

As the crosslinked polyether-modified silicone, it is preferable to use a paste-like polyether-modified silicone composition previously kneaded with a silicone oil under a shearing force. And silicone oil or the like as a cosmetic ingredient. For example, the kneading treatment can be performed after blending a crosslinked polyether-modified silicone oil and a silicone oil, and if necessary, other cosmetic ingredients.

In using the crosslinked polyether-modified silicone of the structural formula (I) in the present invention, 1 is 3
~ 20 is preferred. If it is less than 3 and deviates from this range, the paste composition obtained by kneading the crosslinked polyether-modified silicone and silicone oil under a shearing force has poor emulsifiability of water. Swelling property is not sufficient, which is not preferable. Also, m is 10
When it is more than 200, the paste-like polyether-modified silicone composition obtained by kneading with the silicone oil under a shearing force is not water. Becomes poor in emulsifiability.

Further, n is preferably from 1.0 to 10.0, and if n is less than 1.0, a three-dimensional structure cannot be formed, and the mixture does not become a paste-like substance even if it is kneaded with silicone oil. Is also inferior in emulsifiability. Conversely, if it exceeds 10, the crosslink density of the three-dimensional structure becomes too high.
Even if it is kneaded with the silicone oil, the silicone oil cannot be retained, and the paste does not become stable, which is not preferable.

In the present invention, the silicone oil to be kneaded with the crosslinked polyether-modified silicone is not particularly limited, and may be linear or branched. Although possible, a low-viscosity silicone oil having a viscosity at 25 ° C. of 100 mPa · s or less can be preferably used.

Specific silicone oils that can be used include:
Cyclic dimethylpolysiloxane such as methylpolysiloxane, methylphenylpolysiloxane, ethylpolysiloxane, ethylmethylpolysiloxane, ethylphenylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and the like. You may mix and use more than one kind.

The mixing ratio of the crosslinked polyether-modified silicone and silicone oil in the present invention is based on 100 parts by weight of the crosslinked polyether-modified silicone.
The amount of the silicone oil is preferably 10 to 1000 parts by weight, more preferably 20 to 500 parts by weight. If the amount of the cross-linked polyether-modified silicone is less than the above range, a stable and good gel structure cannot be maintained, and if the amount exceeds the above range, weight is felt on the skin (that is, the Lack of extensibility)
Or, it is not preferable because the usability (feel of use) deteriorates.

The amount of the crosslinked polyether-modified silicone used in the present invention to be added to the cosmetic is preferably 0.1 to 10.0% by weight based on the total amount of the cosmetic. If it is less than 0.1% by weight, the aqueous phase component of 50.0% by weight or more of the internal phase cannot be emulsified. Conversely, if it exceeds 10.0% by weight, the elongation is poor and the feeling of use becomes poor. Also becomes heavy, which is not preferable.

When the cross-linked polyether-modified silicone is blended as a paste-like polyether-modified silicone composition, the amount of the cross-linked polyether-modified silicone is adjusted so that the amount of the cross-linked polyether-modified silicone is within the above range. Good to choose. The kneading treatment used for forming the paste-like polyether-modified silicone composition under shearing force is not particularly limited, and a commonly used device can be used. A three-roll mill can be preferably used.

In the emulsified cosmetic of the present invention, in addition to the above-mentioned essential components, oils usually mixed with the emulsified cosmetic can be naturally added within a range not to impair the uniformity of the oil phase. It includes natural animal and vegetable oils in addition to the component (A),
Any of the synthetic oils can be used. As this oil agent,
Specific examples include liquid, pasty or solid hydrocarbons such as liquid paraffin and squalane, waxes, higher fatty acids, higher alcohols, esters, glycerides, silicone oils and the like.

In the emulsified cosmetic, the oil phase component is contained in the cosmetic in an amount of 10% by weight to 5% by weight based on the total amount of the cosmetic.
It is blended in a range of less than 0% by weight. If the amount is less than 10% by weight, it is difficult to make the water-in-oil type cosmetic. If the amount is more than 50% by weight, the amount of water in the internal phase becomes too small, and it is not preferable because it lacks moisture in terms of usability. In addition, as the component corresponding to "O" in the W / O type emulsified cosmetic, there are all oily components such as natural animal / vegetable oil, synthetic oil and the like contained in the cosmetic, and are essential in the present invention. The cross-linked polyether-modified silicone composition and diesters and triesters which are liquid at normal temperature, which are components, are also oil phase components corresponding to “O”.

The aqueous phase component such as water mixed with the oil phase component in the high internal aqueous phase water-in-oil type emulsified cosmetic of the present invention, that is, "W" means a water-soluble component such as water, ethanol and a thickener. Compounds are applicable. In the present invention, the amount of the aqueous phase component is 50% by weight based on the total amount of the cosmetic.
It is blended in a range of less than 90% by weight. The blending amount is preferably 60% by weight or more in water itself, and by doing so, a moist feeling can be imparted, which is preferable. If the amount of the aqueous phase component is less than 50% by weight, the characteristic of water is hardly exhibited and lacks moist feeling. Conversely, if the content is 90% by weight or more, it is difficult to obtain a water-in-oil type.

Next, another one of the emulsified cosmetics of the present invention.
Reference is made to the two essential components, the polyether-modified silicones of component (B). The polyether-modified silicone used in the present invention is represented by the above structural formula (II), and one kind or two or more kinds are used.

Examples of the acyl group represented by R ′ in the structural formula (II) include a formyl group, an acetyl group, a propionyl group, a butyryl group, an acryloyl group,
Examples include a benzoyl group and a toluoyl group, and have 1 to 1 carbon atoms.
As the alkyl group of 4, specifically, a methyl group, an ethyl group, an i-propyl group, an n-propyl group, a t-butyl group,
Examples thereof include an n-butyl group.

In the above polyoxyalkylene group of the structural formula (II), when a or b is less than 5,
If the polyether-modified silicone does not show a sufficient surface active effect, and if it exceeds 50, the resulting composition will have a sticky feeling. Its structural formula (II)
The content of the polyoxyalkylene group in the molecule represented by the formula (that is, the polyether-modified silicone represented by the structural formula (II)) is not particularly limited, but the content of the polyoxyalkylene group is determined by the total molecular weight. 20% by weight
Is desirable. This is because when the content of the polyoxyalkylene group is 20% by weight or less, the emulsifiability of the polyether-modified silicone is significantly reduced.

M is from 301 to 1000, and n is from 1 to 40. This is because when m is 300 or less and n is less than 1, emulsification stability is poor, and m
Is more than 50 and 300 or less, and n is 1 to 40, on the contrary, the emulsification stability becomes too good, and the phase inversion feeling characteristic of the present invention cannot be obtained. If m exceeds 1000 and n exceeds 40, the resulting composition will have a sticky feeling. Also, m: n is preferably 200: 1 to 5: 1, and 60: 1 to 60: 1.
A ratio of 15: 1 is particularly preferred.

Although the molecular weight and the viscosity at 25 ° C. of the polyether-modified silicone used in the present invention are not particularly limited, the polyether-modified silicone is formed from a stable emulsion and has a dry feeling. When the viscosity of a 50% by weight solution of octamethyltetrasiloxane or isoparaffin is 1000-1.
It is particularly desirable to be in the range of 00000 mPa · s.

The blending amount of the polyether-modified silicone used in the present invention is 0.01 to less than 5.0% by weight, and more preferably 0.05 to 3.0% by weight. If the amount of the polyether-modified silicone in the composition of the present invention is less than 0.01% by weight, stable emulsification is difficult, and the emulsification is broken in a vibration test or a fir test of a tube product. That is, the stability at the time of pipe transfer during mass production or the stability at the time of repeated extrusion use cannot be expected. On the other hand, when the content exceeds 5.0% by weight, the emulsion stability becomes too good, and the phase inversion of the cream, which is a feature of the present invention, into water is lost, and the composition becomes sticky. It is.

In the emulsified cosmetic of the present invention, in addition to the above-mentioned essential components, an aqueous component and an oily component which are usually blended in the emulsified cosmetic can of course be contained, such as a humectant and a preservative. , Antioxidants, UV absorbers,
There are beauty ingredients, fragrances, fragrances, thickeners, color pigments, photovoltaic pigments, organic powders, hydrophobized pigments, tar pigments, etc.
They can be blended within a range that does not impair the effects of the present invention.

The specific form (dosage form) of the high internal water phase water-in-oil type emulsified cosmetic of the present invention is, as described above, an emulsion, a skin cream, a hair cream, a liquid foundation, an eyeliner, a mascara, and an eye shadow. And the like, and the preparation of these products can be carried out by a conventional method using the above-mentioned essential components and the components usually blended in cosmetics.
