Description

Technical Field

[0001] The present invention relates to an oil-dispersed stick cosmetic composition containing a vegetable butter having improved spreadability and excellent sticky feel. Background Art

[0002] Oil-dispersed stick cosmetic compositions are attracting much attention from consumers recently because they can be easily applied to the skin without the use of additional products such as a puff, are convenient, and have excellent moisturizing properties.

[0003] Generally, due to the characteristics of the product prepared in a solid form, a stick-shaped cosmetic composition is prepared by including a plant wax or a synthetic wax having a high melting point (e.g., 70° C. to 80° C.) in order to improve the stability of the product. However, the stick-shaped cosmetic composition has high molding stability at high temperatures, but has the following disadvantages, namely, poor spreadability due to the large amount of plant wax or synthetic wax used, and is viscous when used due to the high oil content.

[0004] On the other hand, when vegetable butter has a solid or solid-like form depending on the temperature, the hardness changes with the temperature, and the cosmetic spreadability is improved due to the property that it is easily pushed even with a small force. Vegetable butter is a vegetable fat that not only has a unique aroma, but also has a low melting point of between 25°C and 45°C, so it is mainly used in cream-form cosmetic compositions rather than solid-form cosmetic compositions. Vegetable butter has a problem that, due to the low melting point, it precipitates from the product over time when preparing a stick-shaped cosmetic composition.

[0005] Therefore, there is an urgent need to develop a cosmetic composition that contains vegetable butter to improve the feeling of application and stickiness, which are the disadvantages of existing oil-dispersed stick-shaped cosmetic compositions, and to improve the precipitation phenomenon caused by the low melting point of vegetable butter. Summary of the invention

[0006] Therefore, the present inventors conducted intensive research to develop an oil-dispersed stick cosmetic composition, and improved the feeling of application and stickiness, which are the disadvantages of the existing oil-dispersed stick cosmetic composition, by including vegetable butter, and improved the precipitation phenomenon caused by the low melting point of vegetable butter. As a result, it was confirmed that the oil-dispersed stick cosmetic composition containing vegetable butter, hydrocarbon 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 presents a non-sticky and refreshing feeling during use.

[0007] Therefore, an object of the present invention is to provide an oil-dispersed stick cosmetic composition comprising vegetable butter, hydrocarbon oil and wax, vegetable oil and wax, and ester oil.

DETAILED DESCRIPTION

[0024] Hereinafter, the present invention will be described in more detail with reference to the following examples. However, these examples are only used to illustrate the present invention, and the scope of the present invention is not limited by these examples.

[0025] Preparation Example 1: Preparation of Example

[0026] Examples 1 to 3 were prepared according to the components and contents described in Table 1 below.

[0027] Table 1

[0028]

[0029] All raw materials were weighed into a beaker according to the ingredients and contents listed in Table 1, and then uniformly mixed at 25 rpm for 5 minutes using a vacuum emulsifier (Agi-Mixer) while heating at 75° C. to 85° C. Next, the cosmetic compositions of Examples 1 to 3 were prepared by removing bubbles and cooling.

[0030] Preparation Example 1: Preparation of Comparative Example

[0031] Comparative Examples 1 to 5 were prepared according to the components and contents described in Table 2 below.

[0032] Table 2

[0033]

[0034] All raw materials were weighed into a beaker according to the components and contents listed in Table 2, and then uniformly mixed at 25 rpm for 5 minutes using a vacuum emulsifier (Agi-Mixer) while heating at 75° C. to 85° C. Next, the cosmetic compositions of Comparative Examples 1 to 5 were prepared by removing bubbles and cooling.

[0035] Experimental Example 1: Evaluation of dosage form stability

[0036] The stability of the formulations of Examples 1 to 3 and Comparative Examples 1 to 5 was evaluated. Each cosmetic composition was placed at 4°C, room temperature, 37°C, 45°C, and cycle (the storage temperature was changed to -4°C and 45°C three times every 24 hours) for 1 day, 5 days, 1 week, 2 weeks, and 4 weeks to evaluate the stability of the formulation. The results are shown in Table 3 below. The evaluation criteria are as follows.

[0037] Evaluation Criteria

[0038] ◎: stable;

[0039] △: slightly unstable;

[0040] X: Unstable.

[0041] Table 3

[0042]

[0043]

[0044] From Table 3, it can be confirmed that the dosage forms of Examples 1 to 3 and Comparative Examples 1 and 3 still have good stability 4 weeks after preparation. However, the dosage forms of Comparative Examples 2 and 4 were unstable 5 days after preparation, and the stability of the dosage form of Comparative Example 5 was evaluated to be so low that it could not be formed into a rod shape.

[0045] Example 2: Sensory Evaluation

[0046] Thirty professional female panelists aged 25 to 45 were divided into two groups, and each group appropriately adjusted Examples 1 to 3 and Comparative Examples 1 to 4 for use on the face and back of the hand, and then evaluated for spreadability and stickiness according to the following evaluation. Comparative Example 5 was excluded from the sensory evaluation because the formulation stability was unstable and could not be formed into a stick shape.

[0047] In the above evaluation criteria, spreadability is to evaluate whether the prepared oil-dispersed stick cosmetic composition can be smoothly applied to the face and back of the hand. Stickiness is to evaluate whether the prepared oil-dispersed stick cosmetic composition is applied to the face and back of the hand and whether a sticky feeling is felt on the hand after the cosmetic composition is absorbed.

[0048] Each item was evaluated based on a five-point scale of extremely high (5 points), high (4 points), average (3 points), low (2 points), and extremely low (1 point). For spreadability, a higher score indicates better spreadability, and for stickiness, a lower score indicates lower stickiness. The evaluation results are shown in Table 4 below.

[0049] Table 4

[0050] Classification 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 Sticky feeling 2.1 1.5 1.3 4.2 1.5 2.5 2.5

[0051] As can be seen from Table 4 above, Examples 1 to 3 all showed higher evaluations in the spreadability and stickiness evaluations than Comparative Examples 1 to 4. In particular, Example 2 showed the most excellent spreadability and non-sticky feel during use. However, the spreadability of Comparative Examples 1 to 4 was all lower than 3.0, indicating that the spreadability evaluation was low.
