Description

Oil-dispersed stick cosmetic composition comprising vegetable butter

The present invention relates to an oil-dispersible stick-type cosmetic composition comprising vegetable butter having excellent spreadability and stickiness improvement.

The oil-dispersion stick-type cosmetic composition is not using a separate product such as a puff, and can be easily applied to the skin, so it is convenient and has excellent moisturizing feeling, and thus has been widely spotlighted by consumers.

In general, the stick-type cosmetic composition is prepared to increase the stability of the product by containing a vegetable wax or synthetic wax having a high melting point (eg, 70 to 80 ℃) due to the characteristics of the product prepared in a solid state. However, the stick cosmetic composition has high stability in high-temperature molding, but has disadvantages in that the application is stiff by using 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, when vegetable butter has the form of a solid or a solid analogue depending on the temperature, it improves the spreadability of cosmetics due to the property of being easily pushed even with a small force according to the change in hardness according to the temperature. Vegetable butter not only has a unique fragrance as a vegetable fat, but also has a low melting point of 25 to 45° C., so it is mainly used in cream-type cosmetic compositions rather than solid cosmetic compositions. Vegetable butter has a problem of precipitation from the product over time when manufactured as a stick-type cosmetic composition due to its low melting point.

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

Accordingly, the present inventors have developed an oil-dispersion stick-type cosmetic composition that can improve the feeling of application and stickiness, which are disadvantages of the existing oil-dispersion stick-type cosmetic composition, including vegetable butter, and improve the precipitation phenomenon due to the low melting point of vegetable butter. We have worked diligently 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 oil and fatty alcohol in an appropriate weight ratio does not precipitate vegetable butter from the product, and the vegetable butter is not sticky and fresh. It was confirmed that the feeling of use was shown.

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.

Experimental Example 1. Formulation stability evaluation

The stability of the formulations of Examples 1 to 3 and Comparative Examples 1 to 5 was evaluated. Each cosmetic composition was subjected to the conditions of 4 ℃, room temperature, 37 ℃, 45 ℃ and Cycle (change the storage temperature to -4 ℃ and 45 ℃ every 24 hours and carry out 3 times). After 1 day, 5 days, 1 week, 2 weeks and 4 weeks, the stability of the formulation was evaluated, and the results are shown in Table 3 below. In addition, the evaluation criteria are as follows.

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

Example 2. Sensory evaluation

After dividing into two groups for 30 professional female panelists aged 25 to 45, Examples 1 to 3 and Comparative Examples 1 to 4 were appropriately adjusted in each group to be used on the face and back of the hand, according to the following evaluation criteria The spreadability and stickiness were evaluated. Comparative Example 5 was excluded from the sensory evaluation because the formulation stability was unstable and the stick was not formed.

Applicability among the evaluation criteria was evaluated by gently applying the prepared oil-dispersed stick-type cosmetic composition to the face and back of the hand. The stickiness was evaluated by applying the prepared oil-dispersible stick-type cosmetic composition to the face and back of the hand, and then whether the cosmetic composition was absorbed and there was a stickiness felt in the hand.

Each item was evaluated according to the blot method 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.

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