Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lotion containing polyvinyl alcohol and having an excellent feel upon use.

[0002]

2. Description of the Related Art Conventionally, lotions have been blended with polyhydric alcohols such as glycerin and sorbitol, amino acids such as serine, and organic acids such as lactic acid and citric acid as humectants.

[0003] However, these humectants cannot exert a moisturizing effect when used in a small amount, and may become sticky on the skin when used in a large amount. The feeling of stickiness is often disliked as the feel of lotion, and it is necessary to develop a product that moisturizes the skin without stickiness. As one means, attempts have been made to mix oil-soluble components that suppress stickiness, but in order to stably mix many oil-soluble components, it is necessary to increase the amount of surfactant in proportion thereto, Surfactants, like moisturizers, become sticky on the skin and could not be an effective means.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lotion which is excellent in use feeling (no moist feeling, no emollient feeling, no sticky feeling).

[0005]

The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found that polyvinyl alcohol, a specific nonionic surfactant (polyoxyethylene hydrogenated castor oil), and an oil-soluble component. The present invention has been found that a lotion containing water and water does not stick on the skin, and that a lotion giving a moist feeling and an emollient feeling to the skin can be obtained.

That is, the present invention provides the following component (a):
(B), (c), (d), (a) polyvinyl alcohol (b) polyoxyethylene hydrogenated castor oil (c) oil-soluble component (d) water-containing lotion.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below. The polyvinyl alcohol as the component (a) used in the present invention is obtained by hydrolyzing polyvinyl acetate, and includes a completely saponified type and a partially saponified type in which an acetic acid group is left. In the present invention, the degree of polymerization and the degree of saponification are not particularly limited, but the degree of polymerization is 500 to 3000, and the degree of saponification is 80 to
If it is 99.5, it is easy to mix it into a lotion and it is preferable.

[0008] The amount of the polyvinyl alcohol as the component (a) used in the present invention is preferably 0.01 to 1% by mass (hereinafter, mass% is abbreviated as%), more preferably 0.05 to 0.3%. %, It is easy to mix into a lotion and is excellent in further non-stickiness.

The polyoxyethylene (hereinafter abbreviated as POE) hydrogenated castor oil of component (b) used in the present invention is a nonionic surfactant generally used in cosmetics, and the number of moles of ethylene oxide added However, in the present invention, the number of moles of ethylene oxide added is not particularly limited, and is usually 20 to 100.
It is preferable to add a mole of ethylene oxide, since it can be easily incorporated into a lotion.

The POE-hardened castor oil of the component (b) used in the present invention is not particularly limited, but is preferably 0.01 to 5%, more preferably 0.05%, in lotion.
If it is 0.5%, the emulsifying power is further improved.

The oil-soluble component (c) used in the present invention is not particularly limited as long as it is generally used as an oil-soluble component, but is not particularly limited. Liquid paraffin, hydrocarbons such as squalane, olive oil, jojoba oil, perilla oil, grape seed oil, rapeseed oil, vegetable oil such as tsubaki oil, eucalyptus oil, and other oils, fats, waxes, and hardened oils , Ester oils, fatty acids, higher alcohols, silicone oils, fluorine oils, lanolin derivatives, and vitamin A oil, vitamin A palmitate, vitamin A acetate, riboflavin, vitamin C dipalmitate, ergocalciferol, vitamin E, vitamin E acetate, vitamin E
Oil-soluble vitamins such as nicotinate, beta-carotene,
Astaxanthin, cholesterol, phytosterol, ceramide, eicosapentaenoic acid, docosahexaenoic acid, guaiazulene, benzyl nicotinate, dibutylhydroxytoluene and butylhydroxyanisole. Above all, from the viewpoint of easy incorporation into a lotion and good stability can be obtained, a liquid to paste at room temperature can be preferred.

[0012] The amount of the oil-soluble component (c) used in the present invention is not particularly limited as long as a lotion can be obtained. Is preferable because an emollient effect can be easily obtained.

Although the lotion of the present invention is not particularly limited, its appearance is preferably transparent to translucent, and if the properties are from liquid to viscous liquid, the feeling of use is further improved. The term “transparent to translucent” as used in the present invention means that the average transmittance of the transparent purified water in the visible light region is 1 unit.
When it is set to 00, it means about 15 to 100, and the term from liquid to viscous liquid means about 1 to 10000 mPa · s.

The polyvinyl alcohol of the component (a) used in the present invention is contained in the lotion of the present invention for the purpose of obtaining a moist and non-sticky effect, and is a film-forming agent. It is different from a pack charge or the like which is blended as The oil-soluble component (c) is contained for the purpose of emollient effect, and the component (b) POE-hardened castor oil is used in order to stably blend the oil-soluble component. In the case of a cosmetic containing an emulsion, the polyvinyl alcohol as the component (a) may have an effect such as agglomeration of the emulsion, but by using the combination of the present invention, the polyvinyl alcohol is stable and has excellent feeling in use. This made it possible to obtain lotion.

The lotion of the present invention contains a humectant other than the above essential components, a surfactant, a water-soluble polymer, an antioxidant,
A pH adjuster, a fragrance, an antibacterial agent, a preservative, a cosmetic ingredient, and the like can be blended within a range that does not impair the effects of the present invention.

The method for producing a lotion according to the present invention is not particularly limited, and may be produced by a usual apparatus capable of emulsification and mixing, if necessary, through steps such as heating and cooling. is there. If the production method is specifically exemplified, a method in which the components (b) and (c) are uniformly mixed and then added to (d) in which (a) is dissolved can be exemplified.
