Description

  The present invention relates to a two-component cosmetic that can uniformly cover the surface of hair or skin with an oily component.

  One of the purposes of using cosmetics is to cover the surface of hair or skin with an oily component. When the hair is covered with an oily component, the hair has a gloss, a smooth surface, and is protected from physical forces such as brushing, so that a so-called conditioning effect is obtained. When the skin is covered with an oily component, the skin can prevent excessive water evaporation from the skin surface, and a so-called emollient effect is obtained.

  Conventionally, many cosmetics used for such purposes have been in a single agent type although they are in various dosage forms such as solutions, gels, emulsions and creams.

  These one-component cosmetics for covering the surface of hair or skin with an oily component may cause unevenness even when trying to apply evenly on the hair or skin, or the amount of application may be too sticky. As a result, the effect of the oil component could not be obtained, and the use was poor.

  This invention is made | formed under such a condition, and makes it a subject to provide the cosmetics which can cover the surface of hair or skin uniformly with an oil-based component.

  The present invention comprises (1) a first agent containing a higher fatty acid salt and a second agent containing an acidic component, wherein the first agent and the second agent are sequentially applied to hair or skin. Cosmetics to do.

  The present invention is also the cosmetic according to (1) above, wherein (2) the higher fatty acid salt of the first agent is an alkaline hydrolyzate of jojoba oil.

  The present invention is also the cosmetic according to (1) and (2) above, wherein (3) the acidic component of the second agent is an organic acid.

    The present invention is also the cosmetic according to (1), (2) and (3) above, wherein (4) the first agent contains an oil component in addition to the higher fatty acid salt.

    The present invention is also the cosmetic according to (4), wherein (5) the oily component of the first agent is jojoba alcohol.

  According to the two-component cosmetic of the present invention, the oil component can be uniformly applied to the hair or skin as compared with the conventional one-component type, and can be applied to various external preparations.

Hereinafter, the present invention will be described in detail.
The cosmetic of the present invention contains a higher fatty acid salt in the first agent. In the present invention, when the higher fatty acid salt is dissolved in an aqueous medium and is on the hair or skin, it is dissociated by contact with the acidic component of the second agent to form a higher fatty acid, which is uniform on the hair or skin. It precipitates in. Since this precipitation is from the dissolved state, it becomes very uniform on the hair or skin.

  The higher fatty acid salt in the cosmetic of the present invention exhibits a conditioning effect or emollient effect on the hair or skin as a higher fatty acid by dissociation. Examples include lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, behenic acid, oleic acid, linoleic acid, linolenic acid, coconut fatty acid, jojoba fatty acid, etc. And a straight-chain saturated, unsaturated or branched fatty acid salt, and these salts can be used alone or in combination.

  The counter ion of the higher fatty acid salt is not particularly limited, and may be an alkali metal salt such as sodium hydroxide, potassium hydroxide or sodium carbonate, monoethanolamine, triethanolamine, 2-amino-2-methyl-1-propanolamine or the like. An organic amine salt can be mentioned, and it is appropriately selected depending on the system to be applied and the state of precipitation in the dosage form.

  The kind of the acidic component of the second agent in the cosmetic of the present invention is particularly limited as long as it retains the acid strength that can dissociate the higher fatty acid salt into the higher fatty acid salt when in contact with the higher fatty acid salt of the first agent. Not a thing. And although it also depends on the type and concentration of the higher fatty acid salt, organic acids such as citric acid and lactic acid are preferred for cosmetics for external use on hair or skin.

  Since the total amount of the higher fatty acid salt used in the first agent of the cosmetic composition of the present invention and the acidic component used in the second agent is determined by the degree of the targeted conditioning effect or emollient effect, it is particularly limited. However, the amount of the higher fatty acid is usually added in an amount of 0.1 to 10% by weight, preferably 1 to 5%. The weight ratio between the higher fatty acid salt and the acidic component at this time is determined by the relationship between the dissociation property of the higher fatty acid salt used and the acid strength of the acidic substance.

  In the cosmetic of the present invention, when an oil component is blended in the first agent, the following can be listed as candidates.

  When these oily components are blended in the first agent, the type and amount thereof are not particularly limited, but it is important that the oily component is emulsified with a coexisting higher fatty acid salt so that the system is uniform at least in appearance. This oily component is important because when the higher fatty acid salt is dissociated into the higher fatty acid by the second agent, the emulsification is broken at the same time and it is uniformly deposited on the hair or skin in a mixed state with the higher fatty acid. is there.

  A mixture of jojoba alcohol as the oil component and jojoba fatty acid potassium as a higher fatty acid salt is commercially available under the trade name “Flora Ester K-20W” of Flora Tech, and this can be used as the first agent. it can.

  In the cosmetic of the present invention, it is important to apply the first agent and the second agent in order to the hair or skin, and if applied after mixing in advance, the intended effect of the present invention cannot be obtained. At this time, it is usually preferable to first apply the first agent and then apply the second agent.
