Abstract

The present invention relates to a cosmetic composition of a pump spray type. The cosmetic composition of a pump spray type is mixed with a fixed quantity of surfactants with low HLB values and has an increased spray angle even if a commonly used spray-type container is used, thereby being capable of being uniformly sprayed to a wide area. So, the composition is uniformly applied to the skin even if a little amount of the composition is used and does not flow down to give fresh sense of use. In addition, water-resisting qualities of products are increased with a hydrophobic surfactant, thereby having improved fixing abilities when being used as a make-up fixer.

Description

[0001] Cosmetic composition of pump spray type [0002]

The present invention relates to a transparent pump type cosmetic composition for cosmetics having a spray angle enhancement and a makeup picking ability.

Mist type or easy spraying method such as aerosol can be easily used anytime and anywhere, there is less concern about contamination of the product, and the preference is getting higher because of being able to care for skin dryness with refreshing feeling.

When the viscosity of the contents is high, the minute spray angle is narrowed and the use thereof is not easy, so that the viscosity is limited to the liquid content which is almost free of viscosity, which causes the down stream to occur during use (Patent Document 1). In addition, the purpose of use of the cosmetics using the lotion is to emphasize only the function for replenishing the moisture on the face, and since the skin dryness can not be fundamentally solved except the convenience of the product, the consumer can not satisfy the taste. In order to solve these problems, it is effective not only to replenish moisture but also to moisturize moisture when it is prepared by containing a large amount of moisturizing agent. However, the spray angle which is one of the main factors for determining the quality of cosmetic products for use, There was a problem that it did not.

Therefore, in order to expect a sufficient moisturizing effect without flowing down during use in the quality of the liquid cosmetic composition, development of cosmetics for spraying the particles uniformly at the spraying angle is required.

The present invention relates to a pump-type cosmetic composition containing a surfactant having a low hydrophile-lipophile balance (HLB) value.

In one embodiment of the present invention, the surfactant has an HLB value of 5.5 or less (2.0 to 5.5) and is in a liquid state at room temperature. For example, the surfactant may be selected from the group consisting of SORBITAN SESQUIOLEATE [HLB value: 3.7], sorbitan stearate [HLB value: 4.7], sorbitan isostearate [ HLB value: 4.7], and GLYCERYL STEARATE [HLB value: 3.8].

In the present invention, the surfactant may be included in an amount of 0.1 part by weight to 1 part by weight based on 100 parts by weight of the total weight of the cosmetic composition. If it is contained in an amount of less than 0.1 part by weight, the effect of spray angle enhancement can not be expected as a cosmetic composition to be used, and a cosmetic composition having a fixability has a disadvantage that it is difficult to ensure water resistance. When the amount is more than 1 part by weight, .

The pump type cosmetic composition for poultices according to the present invention may further comprise an aqueous phase, a humectant, a solubilizing agent and an alcohol in addition to the above surfactant.

In the present invention, the water phase includes purified water, and may further include at least one selected from the group consisting of water-dispersed polymers and plant-derived extracts in addition to purified water.

The aqueous phase may contain 70 to 93 parts by weight or 75 to 90 parts by weight based on 100 parts by weight of the entire cosmetic composition. When the amount is less than 70 parts by weight, the spraying power is not good and there is a feeling of stickiness. When the amount is more than 93 parts by weight, the stability of the composition is poor, which is not preferable.

In the present invention, the humectant refers to a hygroscopic material that is water-soluble among the raw materials used in cosmetics, and the kind thereof is not particularly limited, and one or two or more conventional humectants usable in the cosmetic composition may be used. , Polyols such as propylene glycol, butylene glycol and polyethylene glycol, and polysaccharides, organic acids, amino acids, and proteins. The moisturizing agent may be included in an amount of 5 to 20 parts by weight based on 100 parts by weight of the total cosmetic composition. If the amount is less than 5 parts by weight, the composition may have poor stability and may have a problem in stability. If the amount is more than 20 parts by weight, the composition is too sticky and the spray angle is poor.

In the present invention, the solubilizing agent is a raw material which plays an important role in realizing a transparent appearance of the composition and securing the stability over time, and its kind is not particularly limited, and one or two or more conventional solubilizing agents usable in cosmetic compositions may be used PEG-60 HYDROGENATED CASTOR OIL [HLB value: 14.7], POLYSORBATE 20 [HLB value: 16.7], and OCTYLDODECETH-16 [HLB value: 12] can be used in various ways. 0.1 part by weight to 1 part by weight based on 100 parts by weight of the whole cosmetic composition. If the amount is less than 0.1 part by weight, there is a problem in securing the stability of the formulation. If the amount is more than 1 part by weight, skin irritation and stickiness may be caused.

The alcohol may be used in an amount of 1 to 10 parts by weight based on 100 parts by weight of the cosmetic composition in order to dissolve the solvent and the composition for increasing the solubility of the other components. If it is contained in an amount of less than 1 part by weight, there may be a problem in stability, jetting power and preservative ability of the composition, and if it exceeds 10 parts by weight, there is a problem in skin irritation and stability of the composition. The alcohol may be a lower alcohol having 1 to 5 carbon atoms or an alcohol having 6 or more carbon atoms, preferably a lower alcohol having 1 to 5 carbon atoms, more preferably ethyl alcohol.

As can be seen from FIG. 1, the pump type cosmetic composition according to the present invention can exhibit the widest spray angle and superior quality.

According to the present invention, there is provided a method of preparing a cosmetic composition for a personal care, comprising the steps of mixing a water and a humectant to obtain a continuous phase; And a step of adding and stirring a surfactant, a solubilizing agent and an alcohol having a low HLB value to the continuous phase.
