Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel cosmetic, and more particularly, to a cosmetic which is excellent in warm feeling and blood circulation promoting effect. 2. Description of the Related Art In recent years, awareness of health has been increasing in Japan as well, and there is a tendency to seek health and beauty by performing shape-ups by aerobics and various sports. Also, awareness of body care such as esthetics for the purpose of weight loss and trimming proportions has been increasing. Conventionally, such cosmetics for body care have been aimed at maintaining the moisture balance of the body skin and maintaining and improving the homeostasis of the skin. There is an increasing demand for a shape-up effect and a slimming effect. [0003] Various massage cosmetics have been proposed for the purpose of aggressive shape-up and slimming effects. Conventional massage cosmetics are mainly oily creams and lotions, and are used after use. Sticky,
There was a disadvantage in terms of difficulty in washing off. In addition, the massage method includes treatments such as light rubbing, kneading, and grasping. For facials,
Light rubbing and kneading are the main components.On the other hand, for the body, the feeling of use for grasping treatment is important, but when applying to the body, it is also important to feel the warmth during use. Becomes [0004] Examples of cosmetics which improve the above-mentioned drawbacks such as the stickiness of creams and lotions, and which obtain a slimming effect by temporarily increasing the skin temperature and improving blood circulation, include: Japanese Patent Application Laid-Open No. Hei 2-31408 discloses that when applied to a dry body, a feeling of warmth is felt. However, there was a defect that it did not exist at all, and it was not always satisfactory. The inventors of the present invention have conducted intensive studies on conventional cosmetics in order to improve the above-mentioned drawbacks particularly related to the feeling of warmth during use. As a result, polyethylene glycol having a molecular weight of 200 to 20,000 and polyvalent polyvalent Polyoxyethylene of alcohol (hereinafter referred to as POE) and / or polyoxypropylene addition polymer {hereinafter referred to as (POP)}
And one or more kinds selected from the group consisting of polyoxy compounds having an IOB value of 3.5 or less.
(However, except for those containing only polyethylene glycol)
In addition , it has been found that when the water content is 10% by weight or less, it is possible to obtain a cosmetic excellent in a warming feeling and a blood circulation promoting effect even when used for a wet body, and completed the present invention. Means for Solving the Problems That is, the present invention provides the following:
In cosmetics containing 0% by weight or less of water, the following i)
And ii) one or more selected from the group consisting of 3
Weight% or more (however, excluding those containing only i)
The present invention provides a cosmetic characterized by the following.
i) Polyethylene glycol having a molecular weight of 200 to 20,000. ii) A polyoxy compound which is a polyoxyethylene and / or polyoxypropylene addition polymer of a polyhydric alcohol and has an IOB value of 3.5 or less. Hereinafter, the configuration of the present invention will be described in detail. As the polyethylene glycol used in the present invention, those having a molecular weight of 200 to 20,000 are optionally used. Generally, polyethylene glycol 300, 400, 150
0, 6000, 20000, etc. are commercially available. [0008] PO of the polyhydric alcohol used in the present invention
The addition polymer of E and / or POP refers to the addition of POE and / or POP to a polyhydric alcohol nucleus such as glycerin in an amount of 0 to 5
It is one obtained by addition polymerization of 0 mol and having an IOB value of 3.5 or less. The blending amount is the polyethylene glycol and POE of the polyhydric alcohol,
One or more selected from the group consisting of POP addition polymers are combined in an amount of 3% by weight or more based on the weight of the product.
(However, except for those containing only polyethylene glycol)
H) . If the content is less than 3% by weight, the effect of warmth sense in the present invention is undesirably reduced. It should be noted that the IOB (inorganic or
ganic balance) refers to the inorganic and organic properties calculated according to the calculation method by Fujita shown in “Region of Chemistry”, Vol. 11, No. 10, pp. 719 to 725, 1957. It is a value ratio, that is, a numerical value represented by the following equation. IOB value = {inorganic /} organic As a result, the diglycerin (PO
P) 7 mol IOB value of 1.04, Example 4 and Example
6 in 1 mol of diglycerin (POE) (POP) 6
The molar IOB value was 1.18, and the diglycer
Phosphorus (POP) 8 mol has a unique IOB value of 0.967
Is determined. [0010] In the cosmetic of the present invention, it is essential that the water content is 10% by weight or less in order to obtain a warm feeling. If it is 10% by weight or more, sufficient warm feeling and its sustainability cannot be obtained. In the present invention, other humectants can be used. Specifically, glycerin, 1,3-butylene glycol, diglycerin, dipropylene glycol, polyoxyethylene methyl glucoside and the like are used, and one or more of these may be used in combination.
It is particularly desirable from the viewpoint of the effects of the present invention that the blending amount is 80% by weight or more in combination with the above-mentioned POE and POP adducts of polyethylene glycol and polyhydric alcohol. In the present invention, a water-soluble polymer compound can be blended as another component. Specifically, carboxymethylcellulose, carboxyethylcellulose, carboxyvinyl polymer, sodium pectate, polyacrylic acid,
Gelatin and the like, and particularly, a carboxyvinyl polymer is suitably used. Specifically, Hibiswako 10
3, 104, 105 (manufactured by Wako Pure Chemical Industries), Carbopol 93
4, 940, 941, 1342 (manufactured by Goodrich) and the like are arbitrarily used. The amount of the compound is 0.1 in the cosmetic.
3-5% by weight is blended. If it is more than 5% by weight, it is not preferable in terms of stickiness, and if it is less than 0.3%, the thickening effect is not sufficiently exhibited. The cosmetic of the present invention may further contain saccharides, pigments, fragrances, bactericides, inflammatory agents, chelating agents, and viscosity modifiers, depending on the purpose of use. The cosmetic thus obtained can be used on a wet body after bathing,
It has excellent warmth and blood circulation promoting effects. The present invention will be described in detail with reference to the following examples. Note that the present invention is not limited to these examples. The compounding amount is% by weight. Examples 1, 3 and Comparative Examples 1 to 5 The cosmetics of the present invention were prepared, and their organoleptic feeling and warmth were evaluated based on the following evaluation methods.
