Abstract

PURPOSE:A massage cosmetic,obtained by incorporating a carboxyvinyl polymer with another component and neutralizing and thickening the resultant mixture with a basic substance and incorporating a humectant with the resultant system and readily taken by fingers without stickiness and changing the extensibility between the initial and final periods of the massage. CONSTITUTION:A massage cosmetic containing >=15wt%, preferably >=80wt% humectant, e.g. ethylene glycol or glycerol, 0.2-1.0wt% carboxyvinyl polymer and a basic substance, e.g. sodium hydroxide or triethylamine, having preferably a neutralization degree so as to give 4-10pH region. The above-mentioned cosmetic becomes an oilless massage cosmetic containing no incorporated oil (a small amount may be blended).

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention comprises a moisturizing agent of 15% by weight or more (hereinafter referred to as %), a carboxyvinyl polymer of 0.2 to 1.0%, and a basic substance. It relates to a pine surge cosmetic characterized by containing the following.

[Conventional technology]

Conventional pine surge cosmetics are thickened by incorporating a large amount of oil, and the trade-off to this is that they become sticky after pine surge treatment. Also, 1 moisturizer
Summer pine surge cosmetics thickened with carboxyvinyl polymer and basic substances at 0% or less are not sticky, but the moisture evaporates during pine surge, making them difficult to spread.
Furthermore, if you put this cosmetic in a bottle, even if you try to scoop it from the bottle onto your fingertips, it will escape from your fingertips and not land on your fingers, and even if you do manage to scoop it out, it will easily slip off if you point your fingertips downwards. It had the disadvantage that it ran down (hereinafter referred to as ``good or bad adhesion to fingers'').

[Problem that the invention seeks to solve]

In view of the above circumstances, the present inventors have conducted intensive research to improve the above drawbacks, and as a result, the present inventors have made carboxyvinyl polymers 0.
．． By blending 2 to 1.0% of a moisturizing agent into a system that has been neutralized and thickened with a basic substance, the disadvantage of stickiness of conventional pine surge cosmetics, as well as carboxyvinyl polymer and base. 10 moisturizers thickened with sexual substances
% or less, the growth becomes heavy in the middle of the pine surge,
They also discovered that the drawback of poor grip on fingers can be improved, and have completed the present invention.

[Means to solve the problem]

That is, the present invention is a pine surge cosmetic characterized by containing 15% or more of a humectant, 0.2 to 1.0% of a carboxyvinyl polymer, and a basic substance.

Examples of the humectant used in the present invention include ethylene glycol, diethylene glycol, triethylene glycol, higher polyethylene glycols, propylene glycol, dipropylene glycol, and higher polypropylene glycol [, 1,3-butylene glycol, 1 , butylene glycols such as 4-butylene glycol, glycerin, diglycerin, higher voglycerins, sugar alcohols such as sorbitol, mannitol, xylitol, maltitol, glycerin ethylene oxide (hereinafter abbreviated as EO), propylene Oxide (hereinafter abbreviated as PO) adduct, E of sugar alcohols
O, PO adducts, galactose, fructose sugar monosaccharides and their EO, PO adducts, maltose, lactose sugar polysaccharides and their EO.

Examples include PO adducts.

In the present invention, one or more of the above-mentioned moisturizers are blended in a total of 15% or more of the total amount of the cosmetic,
Usually, there is no upper limit, but it is preferably 80% or less.

Carboxy vinyl polymers include Carboball (registered trademark) 934, Carboball 940, and Carboball 941 manufactured by Gutdrich, Hiviswako (registered trademark) 103, Hibiswako 104, and Hibisfuco-105 manufactured by Wako Pure Chemical Industries. . The amount of carboxyvinyl polymer blended is 0.2 to 1.0% based on the total amount of the cosmetic.

Further, basic substances include metal oxides such as hydroxide, potassium hydroxide, and lithium hydroxide, and basic amino acids such as triethanolamine, isopropanolamine, and diisopropanolamine. When neutralizing the carboxyvinyl polymer with a basic substance, it is desirable that the neutralization rate is such that the pH of the pine surge cosmetic is in the range of 4 to 10.

Further, there is no particular limit on the viscosity, but considering that the pine surge cosmetic of the present invention comes off on the finger when trying to scoop it from the container onto the fingertip as mentioned above, the viscosity is 30,000.
cps or higher is desirable.

In addition, the viscosity here is a value measured with a rotor 1117 of a BH-type viscometer manufactured by Precision Industrial Research Institute, and a rotation speed of 1 Or, p, m.

In addition to the above-mentioned essential ingredients, the cosmetic of the present invention may optionally include water, liquid oil, wax, surfactant, lower alcohol, within a qualitative and quantitative range that does not impede the effects of the present invention.
Water-soluble polymer thickeners other than carboxyvinyl polymers,
Fragrances, antioxidants, chelating agents, dyes, pigments, preservatives
In addition to ingredients commonly used in cosmetics, such as agents, medicinal ingredients, and ultraviolet absorbers, inorganic or organic powders, granules, and other ingredients can also be blended.

If an inorganic or organic powder is added, the above-mentioned stickiness on the fingers will be even worse.This effect can only be expected when the powder is added at 0.5% or more.
There is no particular upper limit, but strictly speaking it is 10% or less.

〔Effect of the invention〕

The product of the present invention is an oil-free pine surge cosmetic that does not contain any oil (a small amount is allowed), is non-sticky, does not change its application from the beginning to the end of the pine surge, is easy to spread, and easily applies to fingers. This is a pine surge cosmetic with excellent pine surge effects.

〔Example〕

Next, Examples and Comparative Examples will be given to specifically clarify the present invention. The present invention is not limited thereby. The blending amount is in weight%.

An opaque jelly-like pine surge cosmetic of No. s was obtained. In this way, for example, when organic powder (nylon powder in this example) is blended into the pine surge cosmetic, the ease with which it can be removed from the fingers is further improved. Here, Example 1.2 and Comparative Examples I, 2
The usability evaluation results are shown in Table 1. The usability was evaluated using the following method.

A practical use test was conducted by a panel of 20 beauty technicians, and a sensory evaluation was conducted. The evaluation items were 4 items: ease of removal from the container with fingertips, non-stickiness, ease of spreading and pine surge), and satisfaction with pine surge.

The evaluation results will be expressed as follows.

A: Six or more of the 20 middle school children answered that it was good.

B: Out of 20 children, 2 to 15 answered that it was good.

C: 20 to 11 respondents answered that it was good.

D: 20 people answered that the middle child name or less was good.

Table 1 As is clear from Table 1, the viscosity is 30,000 cps or more.
Example 1.2 is Comparative Example 1 with a viscosity of less than 30,000 cps.
It can be seen that it applies better to the fingers and spreads more easily than before, and there is less change in the spreadability during the pine surge.

In addition, when compared with Comparative Example 2, which is a conventional manosage cream, Example 1.2 is less sticky, has less change in spreadability during pine surge, and has an excellent feeling of satisfaction after pine surge.

A 0/8 solution was added to a portion of the mixture to neutralize and increase the viscosity, thereby obtaining a jelly-like pine surge cosmetic containing half-metal granules with a viscosity of 100,000 cps.

In this way, when granules are incorporated into pine surge cosmetics, the pine surge effect is further promoted.

However, - although the following formulation can be considered as an example of the above granules, it is not limited to this.

As for the granules that can be incorporated into this pine surge cosmetic, it is necessary to granulate them using water-insoluble bases as represented by item (2) and binder represented by item (). Furthermore, when the above-mentioned granules are blended into conventional oil-based pine surge creams, there is a problem with the long-term stability of the granules, but even when blended into the jelly-like pine surge cosmetic of the present invention, the other oils blended are non-polar. It is known that there is no problem in this case.
