Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a lotion. More specifically, you can get a soft and moist feel during use, and you don't feel sticky or slimy.
The present invention relates to a lotion having a unique feeling of use.

[0002]

2. Description of the Related Art Lotion is applied to the skin to
By giving moisture and moisturizing ingredients to the skin, it has the effect of keeping healthy skin by maintaining a moisture balance, and by adding ingredients according to the purpose,
It is possible to have effects such as flexibility, convergence, and cleaning.

[0003] At the same time as such effects and effects, the lotion gives the user a pleasant feeling of use.
It is important that psychological satisfaction is obtained by using it. A pleasant feeling when using a lotion includes a refreshing feeling, a richness, and familiarity. To improve the feeling of use, a refreshing agent such as alcohol or menthol is used to improve the refreshing feeling. To improve the blending, richness and familiarity, moisturizers and thickeners (mucus),
The emollient agent (oil content) is mixed.

[Problems to be Solved by the Invention]

Of these feelings of use, a thickener has been conventionally blended in order to improve the richness during use.
Even if a thickening agent is added in a larger amount in order to further improve the richness, it may cause an unpleasant slimy feeling during use and increase stickiness after use, which is a factor that adversely affects the feeling of use. , I couldn't fully improve the body.

In view of the above situation, the inventors of the present invention have conducted earnest studies to improve the richness during use, and at the same time, to obtain a lotion that does not feel sticky or slimy.
By blending polyethylene glycol having an average molecular weight of 1,000,000 to 5,000,000 with a water-soluble polysaccharide, it is possible to obtain a soft and moist feel during use, and yet not feel sticky or slimy.
They have found that a lotion having a pleasant feeling of use can be obtained, and completed the present invention.

[0006] An object of the present invention is to provide a lotion which gives a soft and moisturizing feel during use and which does not feel sticky or slimy and has a pleasant feel during use.

[0007]

That is, the present invention provides a lotion containing a polyethylene glycol having an average molecular weight of 1,000,000 to 5,000,000 and a water-soluble polysaccharide.

The present invention also has an average molecular weight of 1,000,000.
The content of polyethylene glycol is ~ 5,000,000
0.001-0.1%, the content of water-soluble polysaccharide is 0.005-
It provides 0.5% of the lotion described above.

Furthermore, the present invention provides the above-mentioned lotion, wherein the water-soluble polysaccharide is alginate.

The present invention also provides the above-mentioned lotion, wherein the water-soluble polysaccharide is xanthan gum.

Hereinafter, the configuration of the present invention will be described in detail. Polyethylene glycol is a water-soluble polymer composed of a homopolymer of ethylene oxide, and generally has an average molecular weight.
Up to 5,000,000 are known. Polyethylene glycol is known to be used in cosmetics, and examples of its disclosure include JP-A-61-4760.

The polyethylene glycol used in the present invention has an average molecular weight of 1,000,000 to 5,000,000, and a commercially available product corresponding to this is Polyox W
SR-301 (Union Carbide) has an average molecular weight of 4,000,000, Pol
yox Coagulant (Union Carbide) average molecular weight 5,000,0
At 00, these can be used.

Examples of the water-soluble polysaccharides used in the present invention include gum arabic, xanthan gum, guar gum, karaya gum, tragacanth gum, carrageenan,
Examples include dextran, amylose, amylopectin, pullulan, agarose, sodium pectate, sodium alginate, methyl cellulose, ethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, sodium chondroitin sulfate and the like. One or more of these water-soluble polysaccharides can be arbitrarily selected and used.

Among these water-soluble polysaccharides, alginate or xanthan gum is particularly preferable.

In the present invention, the content of polyethylene glycol is in the range of 0.001 to 0.1% by weight. A blending amount of less than 0.001% by weight does not give a sufficient rich feeling on use, while a blending amount of more than 0.1% by weight causes a slimy feel during use, pulling a thread, and the likeness is reversed. In any case, the result is not satisfactory because it becomes worse.

Further, in the present invention, the blending amount of the water-soluble polysaccharide is 0.005 to 0.5% by weight. A blending amount of less than 0.005% by weight does not give a sufficient rich feeling on use, while a blending amount of more than 0.5% by weight gives a slimy feeling during use and causes a sticky feeling after use. In any case, the result is not satisfactory because it becomes worse.

In the lotion according to the present invention, in addition to the above-mentioned essential constituent components, if necessary, components generally contained in cosmetics can be blended. As those components, lower alcohols such as ethanol and isopropyl alcohol, polyhydric alcohols such as glycerin, propylene glycol, dipropylene glycol, 1,3-butanediol, sorbitol and maltitol, liquid paraffin, higher alcohols, ester oils, Oil such as methylpolysiloxane, powder of talc, kaolin, silicic acid anhydride, etc.
Examples thereof include anionic surfactants, amphoteric surfactants, nonionic surfactants, preservatives, bactericides, ultraviolet absorbers, chelating agents, antioxidants, and fragrances.

The method of using the lotion of the present invention is the same as that of a normal lotion, and an appropriate amount is taken on a hand or cotton and applied to the face. It can also be used by putting it in an inner stopper container with a sponge, a spray type dispenser container, or the like.
It can be used not only on the face but also on the whole body such as arms and legs.

[0019]

The present invention will be specifically described below with reference to examples, but the present invention is not limited to these examples. Prior to the examples, the evaluation method used in each example will be described.

[Sensory Evaluation Test] Sensory evaluation was carried out by 10 female panelists in their 20s. The test method was to apply about 1.5 ml of the sample to the entire face after washing the face and to feel the feeling during and after use.
A score was assigned according to each of the following items, and the average score was evaluated as follows. Score (Item 1) Rich 2: Feels rich 1: Feels slightly rich 0: Does not feel rich (Item 2) Feels slimy 2: Does not feel slimy 1: Feels slimy 0: Feels slimy (Item 3) Stickiness 2: Not sticky 1: Slightly sticky 0: Sticky (Item 4) Thread pull 2: Do not pull thread 1: Slight pull thread 0: Thread pull is annoying Rating ○: Score average 1.0 or more △: Score Average 0.5 or more x: Score average less than 0.5

A lotion having the composition shown in the following Tables 1 and 2 was prepared, and its sensory evaluation test was conducted.
