Description

Gel type cosmetic compositions for spraying

The present invention uses a gellan gum and metal ions or salts, while having a gel form, feels fresh and easy to spray, and does not flow down when spraying on the skin, which can impart moisture and beauty effects to the skin by simple usage. It relates to a cosmetic composition used.

Unlike the past, where rich and nutritious lotions were preferred, consumers have increased their preference for lotions with moderate moisturizing and nutritious, fresh feeling and convenient usage. Accordingly, there is an increasing trend in the product range of simply spraying and using, such as mist type or aerosol.

When the type of spraying is high, the spray angle is narrowed when the viscosity of the content is high, because it is not easy to use, it is generally limited only to the content of the liquid form almost no viscosity, there is a disadvantage that the flow occurs when using .

Gellan gum is obtained by purifying polymer polysaccharide gum material obtained by pure culture and fermentation of microorganism (Pseuudomonas dlodea) in carbohydrate with isopropyl alcohol, drying and grinding. Rhamnose, glucuronic acid and glucose are heteropolysaccharides consisting of 1: 1: 2. Glucuronic acid is neutralized by mixing potassium, sodium, calcium and magnesium salts. Gellan gum is an off-white powder that dissolves in deionized hot or cold water, forms gels in small amounts, and is produced by microbial fermentation to maintain a constant quality. In addition, it is excellent in stability of various structures such as brittleness and elasticity, heat, pH, enzymes, etc., and its applicability is good because of its transparency.

When gellan gum is dispersed and hydrated in water at a high temperature and cooled without physical stress, an excellent gel is formed.

However, when shear is applied during cooling, a weak gel is formed in which the bond inside the gel is weakened, and even if a small force is applied to the weak gel, the viscosity becomes very low, resulting in a fluid-like flowability. Gels (fluide gel) have a strong dispersion capacity with little increase in viscosity. Therefore, by appropriately adjusting such a fluid property, it is possible to provide a gel type cosmetic composition for spraying easy to use and fun appearance.

Accordingly, the inventors of the present invention have invented a gel-type spray cosmetic having a neat feel while maintaining a gel form while spraying evenly using a spray mist and aerosol container for easy use.

The present invention is a gel having a slight viscosity by dissolving purified water and sodium citrate and then gelling the gellan gum by adding and cooling the metal ion or metal salt while heating, and applying high pressure shear to the gelled contents. A gel-type spraying cosmetic composition to which gellan gum is added, which is made through a step of pulverizing into a type, is shown.

In the step of gelling, 0.1 to 10.0% by weight of sodium citrate and 0.01 to 10.0% by weight of gellan gum powder, preferably 0.01 to 0.8% by weight, are sufficiently stirred and then heated to 80 to 120 ° C with 10 to 20% by weight of the composition. Stir for minutes.

In addition, during gelation, a 1,2-valent metal ion or a metal salt (for example, calcium lactate or calcium chloride) may be added in an amount of 0.001 to 1.0 wt% based on the total weight of the composition.

In the grinding step, a high pressure shear force can be applied by a roller mill or an agitator, and it is preferable to grind at 4000 to 5000 rpm using a homogenizer.

Referring to the present invention in more detail as follows.

In the present invention, 0.1-10.0% by weight of sodium citrate and a moisturizer, etc., are added to purified water, and after completely dissolving, gellan gum powder is added and stirred for 10-20 minutes while heating to 80-120 ° C. Gellan gum powder used in the present invention is used 0.01 to 10.0% by weight of the total weight of the composition, preferably 0.01 to 0.8% by weight. If the gellan gum powder is 0.01% by weight or less it is difficult to expect the proper viscosity is formed, when containing more than 10.0% by weight it is difficult to spray the contents because the viscosity is formed too high. Since 1,2-valent metal ions or metal salts are dissolved separately in purified water, and then stirred for 3 to 10 minutes. Metal ions or metal salts used in the present invention include K +, Na +, Ca + +, Mg + +, calcium lactate, calcium chloride, and the like, preferably calcium chloride.

The viscosity, gelation point, and melting point of the gel formed when the gellan gum is applied are all affected by ions, and the gelation point and melting point are both increased as the amount of ions increases.

Below, gellan gum and the effects of calcium ions on the gel strength at 1.2 wt% and 1.5 wt% concentrations were indicated.

After cooling to 40 ~ 50 ℃ begins to form a gel, at this time by adding ethanol, flavoring, moisturizers, etc. by grinding homogenizer at 4000 ~ 5000 rpm for 5 minutes and then cooled to room temperature to complete the manufacture.

In the case of simple agitation without grinding with a homogenizer, the contents are in the form of granules and the grain size is uneven.

The gel-type cosmetic composition for spraying according to the present invention has a gel form, but even when applied to a spray-type container, it is possible to use the same spray as a general liquid type, and is easy to use. In addition, it is possible to form a gel in a small amount, it is possible to impart a moisturizing effect to the skin with no stickiness and a fresh feeling. Using these formulation properties, it is possible to apply to a variety of products from products that can be easily used for topical areas to body products.

Hereinafter, the present invention will be described by the following examples. However, these are not limited to the scope of the present invention by these as an embodiment of the present invention.

Separately dissolved ethanol, fragrance, Methylparaben, pigment, etc. are added, and then pulverized at 4000 ~ 5000 rpm with a homogenizer, and then degassed. The prepared stock solution was put in a pressure resistant container, and filled with a propellant (dimethyl ether) to prepare the same.

Comparative Example 3: Comparative Example 3 was prepared in a conventional manner according to the same prescription as in Example 3, except that gellan gum was not used.

Experimental Example: Sensory Test

Examples 1 to 3 and Comparative Examples 1 to 3 were prepared and tested in 20 healthy male / female subjects as being filled in a mist container and a pressure vessel (aerosol).

In the test method, after spraying a sample on the tester's cheek-maxillary area after washing the face, the sample was left for 30 seconds to observe the degree of flow. Afterwards, the sensor was rubbed for 1 minute and subjected to a sensory test for feeling. The results are shown in Table 7.

5 points: Very good (evenly sprayed, no dripping, no sticky)

4 points: good

3 points: normal

2 points: defective

1 point: very bad

As shown in Table 4, the gellan gum was more excellent than the comparative example using the same amount of other thickeners such as carbomer and xanthan gum. In addition, despite the relatively high degree of increase in gellan gum, even when spraying was found to be more even and spread.
