Vegetable butter, hydrocarbon-based oil and wax, vegetable oil and wax, and ester-based oil are mixed at a proper mixing ratio to embody a stable solid formulation which has the excellent effects of showing a high sensation of spreadability, and reducing a sticky sensation, and also preventing vegetable butter from being deposited thereon.

Description

Oil-dispersed stick-type cosmetic composition containing vegetable butter

This patent application claims priority to Korean Patent Application No. 10-2021-0120420 filed with the Korean Intellectual Property Office on September 9, 2021, the disclosure of which is incorporated herein by reference.

The present invention relates to an oil-dispersed stick-type cosmetic composition containing vegetable butter, which is excellent in improving spreadability and stickiness.

Oil-dispersion stick-type cosmetic compositions have recently been widely spotlighted by consumers because they can be easily applied to the skin without using a separate product such as a puff, and are convenient and have an excellent moisturizing effect.

In general, stick-type cosmetic compositions contain vegetable wax or synthetic wax having a high melting point (eg, 70 to 80 ° C.) due to the characteristics of products manufactured in solid form to increase product safety. However, the stick cosmetic composition has a high stability in high temperature molding, but has a disadvantage in that application is stiff due to the use of a large amount of vegetable wax or synthetic wax, and the feeling of use is sticky due to a lot of oily feeling.

On the other hand, if vegetable butter has a solid or solid analogue form depending on temperature, it improves the application of cosmetics due to its property of being easily pushed even with a small force according to the change in hardness according to temperature. Vegetable butter not only has a unique fragrance as a vegetable fat, but also has a low melting point of 25 to 45 ℃, so it is mainly used in cream-type cosmetic compositions rather than solid-type cosmetic compositions. Vegetable butter has a problem in that it precipitates out of the product over time when manufactured as a stick-type cosmetic composition due to its low melting point.

Therefore, the development of an oil-dispersed stick-type cosmetic composition that can improve the application feeling and stickiness, which are disadvantages of existing oil-dispersed stick-type cosmetic compositions including vegetable butter, and improve the precipitation phenomenon due to the low melting point of vegetable butter It is an urgent situation.

Therefore, the inventors of the present invention developed an oil-dispersed stick-type cosmetic composition that can improve the application feeling and stickiness, which are disadvantages of existing oil-dispersed stick-type cosmetic compositions, including vegetable butter, and improve the precipitation phenomenon due to the low melting point of vegetable butter. Efforts were made to develop it. As a result, the oil-dispersed stick-type cosmetic composition containing vegetable butter, hydrocarbon-based oil and wax, vegetable oil and wax, ester-based oil and fatty alcohol in an appropriate weight ratio does not precipitate vegetable butter from the product, and is not sticky and refreshing. It was confirmed that it shows a feeling of use.

Accordingly, an object of the present invention relates to an oil-dispersed stick-type cosmetic composition comprising vegetable butter, hydrocarbon-based oil and wax, vegetable oil and wax, and ester-based oil.

As can be seen from Table 3, Examples 1 to 3 and Comparative Examples 1 and 3 had good formulation stability even after 4 weeks after manufacture. On the other hand, in Comparative Examples 2 and 4, the formulation was observed to be unstable after 5 days of manufacture, and in Comparative Example 5, the stability of the formulation was evaluated so low that stick formation was impossible.

Example 2. Sensory evaluation

30 professional female panels aged 25 to 45 were divided into two groups, and Examples 1 to 3 and Comparative Examples 1 to 4 were appropriately adjusted for each group to be used on the face and back of the hand, according to the following evaluation criteria Spreadability and stickiness were evaluated. Comparative Example 5 was excluded from the sensory evaluation because the formulation stability was unstable and no stick was formed.

Among the above evaluation criteria, applicability was evaluated for smooth application of the prepared oil-dispersion stick-type cosmetic composition on the face and back of the hand. For stickiness, after applying the prepared oil-dispersed stick-type cosmetic composition to the face and back of the hand, whether or not there was stickiness felt in the hand after the cosmetic composition was absorbed was evaluated.

Evaluation of each item was performed according to the five-point standard of very high (5 points), high (4 points), normal (3 points), low (2 points), and very low (1 point). The higher the score, the better the spreadability, and in the case of stickiness, the lower the score, the less stickiness. And the evaluation results are shown in Table 4 below.

division	Example 1	Example 2	Example 3	Comparative Example 1	Comparative Example 2	Comparative Example 3	Comparative Example 4
spreadability	3.4	4.0	3.6	2.5	1.6	1.5	1.8
stickiness	2.1	1.5	1.3	4.2	1.5	2.5	2.5

As can be seen in Table 4 below, Examples 1 to 3 showed higher evaluations in the evaluation of spreadability and stickiness than Comparative Examples 1 to 4. In particular, Example 2 showed the best application and non-sticky feeling. On the other hand, it was confirmed that all of Comparative Examples 1 to 4 had a low spreadability of 3.0 or less.

The present invention relates to an oil-dispersed stick-type cosmetic composition containing vegetable butter, which is excellent in improving spreadability and stickiness.
