Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to improvements in oil-based beauty cosmetics (eg pomades, hair creams, etc.). Furthermore, the present invention relates to an oil-based hair styling cosmetic that has a small temperature dependence of hardness, is easy to remove during use, has a soft, light and mild feel, and is stable even after long-term storage.

111! Rice, Pomade Kano, is generally a cosmetic whose hardness is highly dependent on temperature, and in the 4th season it tends to be hard, flaky, flaky, etc., and the hardness of the kit in the summer season decreases significantly, making it difficult to use. be. Therefore, there is a demand for products that can be applied throughout the year, and various improvement methods have been proposed. Many problems remain, such as a decrease in stability and transparency.

The inventors of the present invention have studied the current situation and have made their own research.
% Kiguchi Rito and mustard oil emulsion material in a homogeneous mixture system to produce a homogeneous dispersion agent),
This product is stable and has low hardness even after long-term storage.
A turtle whose temperature dependence is also small.

It was discovered that the peeling, groaning, and sensation @buttocks were also better during use, and the present invention was completed. A cream (milky white) oil-based hair styling cosmetic that is easy to apply, gives a soft and mild feeling, and has excellent storage stability and spreadability.
I have something to offer. Namely.

The main constituent components of the present invention essentially consist of wood grain, castor oil, and an inert gas, and the inert gas is uniformly dispersed in the system of the homogeneous mixture of the oil-based substances, The entire system is characterized by the formation of a milky white cream. Oil-based hair styling cosmetics. In addition, after melting and mixing an oily substance consisting essentially of wood grain and castor oil, this oily substance mixture is held at 40 to 70°C and vigorously stirred for 1 hour to remove inert gas from the atmosphere and convert it into an oily substance mixture. and/or blowing pressurized inert gas into the oily product, thereby
It is characterized by uniform dispersion and subsequent cooling.

This is a method for producing a milky white creamy oil-based hair styling cosmetic.

Skin transformation! L: Forms a milky white cream-like appearance like a skin cream, and contains wood wax,
It is also significantly different in appearance from the conventional (ordinary) pomade (transparent and does not contain air bubbles) made of Castor M (takashi Klf-formed Castor 111I).

6- In addition, the milky white cream-like color of the hair styling cosmetic of the present invention is similar to that described in the previous article.
This is due to the homogeneous dispersion of an inert gas into an oily substance mixture consisting of the following ingredients, and is not an emulsion like a skin cream.

It is non-aqueous (oil-based) and does not emulsify with water. Therefore, such oil-based makeup 1i of the present invention
! For example, non-aqueous creamy pomade.

You can call it a non-aqueous hair cream.

Examples of the inert gas that is uniformly dispersed in the oil-based product system of the present invention to form an emulsified cream-like color include air and nitrogen gas.

carbon dioxide gas, etc., and its content is determined by the cosmetic (II).
5 to 50% by weight (Kjt) *
11. < 7 to 25% by weight. When the amount is less than 5% by weight, the non-foaming gas bubbles become large and form a milky white cream, which not only becomes a normal transparent to translucent bomber, but also becomes noticeably #'i at low temperatures. The temperature dependence of the so-called hardness, which is hard and soft at high temperatures, becomes large, giving an undesirable 7J-ring with a feel similar to that of ordinary pomade. When it increases by 500% by weight,
The stability against temperature decreases, and the hardness and viscosity decrease over time, making it easy to become flowproof.

The oily substance 11 in Kozuchimei is substantially composed of a wood grain and a castor phase, a wood grain, a castor oil, and a hydrogenated castor oil. If necessary, the #oil-distributing substance and other oily substances with good solubility may be added to IaI that does not reduce the above properties.
A small amount may be blended within PII. Contains wood, 5 to +511% by weight based on the weight of the cosmetic, ul
% by weight.

The content of castor oil is 5% based on the weight of the cosmetic.
The content is 0 to 951% by weight, preferably 55 to 92% by weight. The content of hardened mustard oil is at most 6% by weight, preferably R1 to 4% by weight, based on the amount of cosmetic oil. Other ingredients include antioxidant IE91! However, with the above-mentioned components, the objectives described in IIIJ can be fully achieved,
In the presence of an inert gas, the uniform dispersibility and stability of the above-mentioned IQ inert gas can be made good, and the hair washing process becomes easier by 8%, which is preferable. In this case as well, there is no sweating phenomenon that tends to occur with conventional pomades, and this drawback has also been improved.

Examples of surfactants include 1, for example, Nrubitan monofatty acid ester M, polyoxyethylene sorbitan monofatty acid ester, higher fatty acid sialkannylamide, polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkylphenyl ether% Meri. Oxyethylene hardened castor a high aii fatty acid monoester gauze, polyoxyethylene-polyoxypropylene-iI & Minea wo Ki-ete M, polyoxyethylene seven-higher fatty acid ester/L'4F nonionic surfactant + aL distearyl t
Examples include cationic surfactants such as ammonium chloride.

91 The hardness of the milky white cream hair styling cosmetic of the present invention is:
4 hours considerably lower than conventional pomades containing castor m (also hydrogenated castor oil) as a constituent component 1 For example, the hardness at 25°C measured with a card tension meter is 1 usually 10 to 50% preferable. 17-45. Furthermore, the temperature dependence of hardness is very small compared to the conventional pomades mentioned above, and it is soft.
The viscoelastic properties of conventional pomades of the same hardness are also severely different. It is soft even in the 4th season, can be used in the same way over the whole season, is not hard during long-term storage, and has a sharp release when used.
It does not have the drawbacks of Cong Song pomade, such as giving a slightly sticky feeling, and has been improved. E, it has better long-term stability and applicability, and it is easy to remove during use, and it is easy to use. The effects of using inert gases are unique and useful.

10- According to the present invention, an oil-based hair styling cosmetic having the excellent features # and # is prepared by the above-mentioned method! ll can be built.

In the method of the present invention, melt mixing of the oily substance, introduction of inert gas, straddle blowing percentage and subsequent cooling are as follows:
Usually a strong stirring sound, an inert gas introduction pipe, a heating device,
This is carried out using an M mixer or homogenizer equipped with a cooling device and a strong stirring force. #' in manufacturing! ,
First, the required amount of wood chips is stirred and mixed, and then heated and melted. This brewing temperature is usually 75 to 85°C. The mixed and melted horse mackerel compound 11-hydrate is cooled to a temperature of 40 to 70℃.
51°C (preferably 45-65°C)! Stirring with a force of 1gI will result in homogenization by introducing an inert gas in the surrounding atmosphere into the oily substance mixture and/or by blowing an inert gas into the oily substance mixture. It can be dispersed.

Introducing an inert gas into the atmosphere by vigorously stirring the oil-based substance mixture is performed by stirring the oil-based substance mixture (40 to 70°C) at a high speed of usually 2000 times/min or more while stirring the oil-based substance mixture (40 to 70°C) into the tank space of the mixer. This is done in such a way that the chamber is constantly filled with IFs consisting of an inert gas. When agitating with K11i force in this way, K (natural k) flows in and disperses so that the inert gas forms a surrounding atmosphere and gets caught up in the oily substance.

This method is preferable because the inert gas is more uniformly dispersed than in the above introduction method. The trowel is a method (a combination of the IIIJε double-edged method) in which a pressurized inert gas O1* is introduced into the system while vigorously stirring the oily substance hydrate under an inert gas atmosphere. Inert gas (air, nitrogen gas, #
I! Introducing or blowing inert gas (or a combination thereof) is carried out until the content of inert gas reaches 5 to 50% by weight (preferably 7 to 5% by weight) based on the weight of the final set (product). It will be done.

As the inert gas is uniformly dispersed into the oily substance mixture system, the entire surface of X changes from transparent or translucent to milky white. After the inert gas content has exceeded the required amount, it is cooled to about 15-50°C in the tank of the mixer, or it is cooled in another cooler (for example, an aurator) using the Fi-men 7'. After cooling to about 15 to 50° C., the product is filled into containers as appropriate.

Further, if necessary, it is also possible to further uniformly disperse the inert gas by bringing it into contact with the inert gas while flowing through the cooler.

Examples will be described below. In the examples, % means % by weight, and 1 part means part by weight.

The hardness shown in the examples is the result of measurement using a card tensile meter.

In addition, the quality characteristics of sample cosmetics and the results of practical tests are the results of five specialized inspectors. Also, this is the result of 50 (Netesteteto no Yu*#1 boys).

Pressurized air (5.5 Kt/aj) was blown into this while stirring at a stirring speed of 5,000 times/min.
The mixture is then injected into the system to homogeneously disperse it into the system of the oily substance conjugate. Thereafter, the product was cooled to 25°C and taken out. The obtained oily hair styling product P+ had a milky white cream-like appearance, and its air content was 16.1%. The hardness is 55 at 5°C, 25 at 25°C, and 12 at 45°C.
