Description

Oil cosmetic composition {Oil cosmetic composition}

The present invention relates to an oil cosmetic composition that can be applied to oil products such as body oil, facial oil, and hair oil, and can be molded into various shapes.

Oil for skin application is a complex of various oils and is used to create smooth skin by providing moisture and shine to the skin.

In particular, oils are widely used in fall and winter when the skin is prone to dryness. Looking at the use of body oil, it is usually applied to the entire body after bathing and after wiping off the moisture. Usually, a certain amount of oil is applied to the palm of the hand before use. During this process, due to the low viscosity of the oil, the oil may flow between the fingers, etc., and there is a risk that the user may fall due to the slippery floor. Additionally, the oil flows out during the process of applying it to the skin, making it difficult to apply it evenly.

Due to these inconveniences in using oil, research is continuing to manufacture oil into various formulations using additives in order to be able to manufacture oil into various formulations other than the conventional liquid formulation.

However, when additional additives are added to the oil, the formulation of the oil can be diversified, but the unique properties of the oil as a cosmetic, such as spreadability, feeling of use, and moisturizing power, may be reduced.

For example, Korean Patent Publication No. 2010-0028355 is a transparent stick-type sunscreen cosmetic composition using oil ingredients, and the oil ingredients are manufactured in stick form, but are manufactured as skin care products such as body oil, facial oil, and hair oil. Nothing happened.

In addition, Korean Patent No. 1081195 relates to a body oil that does not flow when applied to the skin, and there was a problem in that the inherent properties of the cosmetic composition, such as feeling of use and spreadability, were deteriorated because an excessive amount of dextrin-based thickener had to be used.

Therefore, there is an urgent need to develop an oil cosmetic composition that has physical properties that can be molded into various formulations while maintaining its unique properties as a cosmetic.

Korean Patent Publication No. 2010-0028355, “Transparent stick type cosmetic composition for sun protection” Korean Patent No. 1081195, “Transparent body oil that does not drip when applied to the skin”

The present inventors conducted various studies to solve the above problems and found that when using an amino acid-based oil thickener when manufacturing an oil cosmetic composition, the viscosity of the oil cosmetic composition increases even if only a small amount of the amino acid-based oil thickener is used. It was confirmed that it can be molded into various forms such as gels, sticks, and cubes, and that it can secure spreadability, feeling of use, and moisturizing power at an equivalent level compared to conventional liquid oil cosmetic compositions.

Therefore, the purpose of the present invention is to provide a moldable oil cosmetic composition.

To achieve the above object, the present invention provides an oil cosmetic composition comprising oil and an amino acid-based oil thickener.

At this time, the amino acid-based oil thickener may be one selected from the group consisting of dibutyllauroylglutamide, dibutylethylhexanoylglutamide, and mixtures thereof.

The amino acid-based oil thickener may be included in an amount of 0.5 to 4% by weight, preferably 0.5 to 2% by weight, based on the total weight of the composition.

Additionally, the oil may include one selected from the group consisting of ester oil, mineral oil, hydrocarbon oil, natural oil, and mixtures thereof.

Additionally, the oil cosmetic composition may be formulated with one or more types selected from the group consisting of gels, sticks, and cubes.

The oil cosmetic composition of the present invention can be molded into various formulations, including gel, stick, and cube, and can meet the various preferences of consumers.

In addition, since the oil cosmetic composition is manufactured using a small amount of an amino acid-based oil thickener, it can provide spreadability, feeling of use, and moisturizing power at an equivalent level or higher compared to conventional liquid oil cosmetic compositions.

In addition, the oil cosmetic composition has a hardness that allows it to be molded into various formulations as described above, making it possible to ensure high temperature stability of the oil cosmetic composition.

Additionally, the oil cosmetic composition can be widely applied as a raw material for oil products such as body oil, facial oil, and hair oil.

For the oil cosmetic compositions prepared in Examples and Comparative Examples, hardness, stability, and feeling of use were measured in the following manner, and the results are listed in Table 3.

(1) Hardness

After preparing the oil cosmetic composition, it was stored at 30°C and the hardness was measured the next day using a rheometer device (CR-500DX-L(S)).

(2) Stability

Stability was evaluated by visually checking the extent to which oil was released from the oil cosmetic composition after storage at -15 ℃, room temperature (25 ℃), 30 ℃, 45 ℃, and 60 ℃ for 4 weeks. The less oil was released, the higher the stability. was judged to be good.

◎: Good, ○: Average, △: Insufficient

(3) Sensory evaluation

After manufacturing the stick-type body oil by molding the oil cosmetic composition into a stick form, a sensory evaluation was conducted on the spreadability, feeling of use, and moisturizing power of the stick-type body oil. It was judged that the better the spreadability, feeling of use, and moisturizing power, the better.

As shown in Table 3, the oil cosmetic compositions of Examples 1 to 6 prepared using an appropriate amount of an amino acid-based oil thickener exhibit moldable hardness, excellent stability, and sensory properties for spreadability, feeling of use, and moisturizing power. It can be seen that all evaluations showed good results.

On the other hand, Comparative Example 1 was a composition that did not contain an amino acid-based thickener, and was manufactured in liquid form, making hardness measurement impossible.

Comparative Example 2 is an oil cosmetic composition prepared using a larger amount of amino acid-based oil thickener than Examples 1 to 6, and the hardness was excessively high, and the sensory evaluation results were also found to be insufficient.

Comparative Examples 3 and 4 were beyond the upper limit of hardness that can be measured using a rheometer device, so hardness measurement was not possible.

Comparative Example 5 is an oil cosmetic composition prepared using a dextrin-based oil thickener instead of an amino acid-based oil thickener, and was found to exhibit hardness sufficient for molding even when 4% by weight of the dextrin-based oil thickener was used. However, Comparative Example 5 had poor stability and usability, so it may be difficult to manufacture it into dosage forms such as gels, sticks, and cubes.

In this way, the oil cosmetic compositions of Examples 1 to 6, which were prepared by using 0.5 to 4% by weight of an amino acid-based thickener as a thickener when manufacturing the oil cosmetic composition, showed excellent results in sensory evaluation including spreadability, feeling of use, and moisturizing power. Since it exhibits excellent stability and hardness enough to be molded into a desired shape, it can be seen that it is possible to manufacture an oil cosmetic composition that can satisfy various tastes of consumers.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims are also possible. falls within the scope of rights.
