Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-in-oil type emulsified cosmetic which contains a large amount of water, has a cool feeling upon application, has no stickiness, and is excellent in stability and long-lasting. Further, the present invention relates to a water-in-oil type emulsified cosmetic which can be made into a solid form so as to be provided in a compact container which is easy to carry. More specifically, water-in-oil containing lipophilic long-chain alkyl, polyoxyalkylene co-modified organopolysiloxane, hydrophilic alkyl group-containing polyoxyalkylene-added nonionic surfactant, silicone oil and water The present invention relates to a water-in-oil type emulsified cosmetic comprising a cationic surfactant or a cationic surfactant.

2. Description of the Related Art Oil-in-water emulsified cosmetics can contain a large amount of water, have a unique refreshing sensation, have excellent moisture retention, and have many desirable properties such as a natural finish. . However, they have the disadvantage that they are easily re-emulsified and lack water resistance, and their makeup is easily disintegrated by sweat. In addition, they are generally unsuitable for being provided in a compact container which has fluidity and is convenient to carry. Therefore, the water resistance is improved by including a large amount of a film forming agent such as a silicone resin, or a combination of io-carrageenan and xanthan gum and / or locust bean gum (Japanese Unexamined Patent Publication No.
279509), water-soluble solidifying agents such as agar, gelatin, and sodium magnesium silicate; and natural polymers such as cellulose derivatives, sodium alginate, carrageenan, and xanthan gum; and synthetic polymers such as polyvinyl alcohol, carboxyvinyl polymer, and sodium polyacrylate. Attempts have also been made to solidify such oil-in-water emulsions by using a water-soluble binder in combination (JP-A-5-178723).

[0003] However, in the above-mentioned technology, even if water resistance is obtained, the elongation is heavy and the usability is deteriorated, and it is necessary to use two or more types of water-soluble binders or solidifying agents at the time of solidification. In addition, it has been necessary to strengthen the control in the manufacturing process in order to impart an appropriate and stable hardness, including the quality control of the water-soluble binder and the solidifying agent. In addition, the oil-in-water emulsion obtained by solidifying the outer aqueous phase with a water-soluble binder is inferior in water resistance, and further requires the container to be airtight during storage to prevent evaporation of water from the outer aqueous phase. There was also.

On the other hand, water-in-oil type emulsified cosmetics are excellent in affinity for skin, maintenance of skin flexibility, water resistance, etc., and may be made into a solid form for storage in a compact container. It was easy, but had a poor refreshing sensation, and also had unfavorable properties such as stickiness and oiliness in terms of usability. When the content of the internal aqueous phase is increased to provide a refreshing feeling, it is difficult to ensure the storage stability of the emulsion. In addition, volatile silicone oils are often included in order to suppress stickiness during use and obtain a feeling of use with low elongation.However, such silicone oils have poor compatibility with other oily components, and also have stable emulsification. It was difficult to maintain.

[0005]

Therefore, in the present invention, the present invention is excellent in water resistance and cosmetic durability, contains a large amount of water, has a refreshing feeling, has good stability, has good elongation, and has no stickiness. It was intended to obtain a water-in-oil type emulsified cosmetic which is also excellent in usability.

[0006]

In order to solve the above-mentioned problems, a stable water-in-oil type emulsion system containing a large amount of an internal aqueous phase was studied. As a result, the outer oil phase contains silicone oil, and as an emulsifier, a lipophilic long-chain alkyl / polyoxyalkylene co-modified organopolysiloxane and a hydrophilic polyoxyalkylene-added nonionic surfactant having an alkyl group are used. By using in combination with the agent,
By obtaining an emulsified system having good stability and feeling of use, and further adding a cationic surfactant,
The inventors have found that the emulsion stability and the pigment dispersibility are further improved, and have completed the present invention.

That is, the water-in-oil type emulsified cosmetic according to the present invention comprises (a) one or more selected from long-chain alkyl and polyoxyalkylene co-modified organopolysiloxanes having an HLB value of 8 or less; b) HL having alkyl group
One or more polyoxyalkylene-added nonionic surfactants having a B value of 12 or more, (c) silicone oil,
And (d) water, or (e) one or more cationic surfactants.

First, the formulations of Examples 1 and 2 used as a skin cream as the water-in-oil type emulsified cosmetic according to the present invention are shown in Table 1 together with the formulations of Comparative Examples 1 to 4. In Table 1, the oil phase components (1) to (5) in Table 1 were uniformly mixed and dissolved by heating to 75 ° C., which was previously mixed and dissolved by heating to 75 ° C. (6) to (9). The aqueous phase component is gradually added with stirring to emulsify and then cooled to prepare. As the cetyl-polyoxyalkylene co-modified methyl polysiloxane (5), methyl polysiloxane / cetyl methyl polysiloxane / poly (oxyethylene / oxypropylene) sold by Goldschmidt under the trade name of ABILEM90 A methylpolysiloxane copolymer (HLB value = 4.5) was used.

[Table 1]

For the examples and comparative examples shown in Table 1,
The state of the emulsion particles was observed with a microscope, and the temperature stability was further evaluated. The temperature stability is such that when each of Example and Comparative Example is stored at -5 ° C, 25 ° C and 40 ° C for 3 months, the temperature is changed at a constant cycle in the range of 40 ° C to -10 ° C. It was observed and evaluated by observing a change in the state when stored while storing and when the freeze-thaw was repeated. The evaluation results were as follows: Regarding the state of the emulsion particles, “○: particle size is small and uniform”, “△: particle size is relatively large but relatively uniform”, “×: particle size and shape are non-uniform”, temperature stability About "○; no change in state is recognized",
"△: Slight change in state of separation, precipitation, etc. of components such as water separation, oil separation, etc.", "X: State change of separation, separation, etc. of constituents such as water separation, oil separation, etc. are clearly recognized" And are summarized in Table 2.

On the other hand, Comparative Example 1, which contained no hydrophilic nonionic surfactant and was emulsified only with cetyl / polyoxyalkylene co-modified methyl polysiloxane, was used in combination with cetyl / polyoxyalkylene co-modified methyl polysiloxane. In Comparative Examples 2 and 3 in which the HLB values of the nonionic surfactants were 7 and 10, respectively, and in Comparative Example 4 in which an anionic surfactant was used in combination, the obtained emulsion particles were slightly larger. Comparative Example 1, Comparative Example 2 and Comparative Example 4 had poor temperature stability.
The stability when stored at 5 ° C. and stored at -10 ° C. to 40 ° C. while changing the temperature was slightly deteriorated.
