Description

Vanishing cream composition with less stickiness and its manufacturing method {VANISHING CREAM COMPOSITION HAVING LOW TACKINESS AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a vanishing cream composition with less stickiness and a method for preparing the same.

The emulsifying cream has a disadvantage of being sticky when applied to the skin by using a large amount of thickener. Accordingly, the present inventors tried to develop a cream with less stickiness that forms viscosity and hardness without a thickener by preparing a vanishing cream using saponification. Vanishing cream is widely used as a cream or ointment as a basic cosmetic product, and plays a big role in protecting the skin from external contamination and microbial invasion, as well as smoothing the skin's function as well as beautifying the skin.

Experimental Example 1: Evaluation of stickiness

An experiment was conducted to evaluate the stickiness of the cosmetic compositions prepared according to Example 1 and Comparative Examples 1 to 3.

Specifically, in order to evaluate the stickiness of the cosmetic composition, 25 adult males and females (age 30±5) were selected, prepared according to Example 1 and Comparative Examples 1 to 3, and then the cosmetic composition was applied to the back of the hand. Then, the degree of stickiness felt on the back of both hands was sensory evaluated.

After absorbing it sufficiently, sprinkle with colored sand and shake off the unattached sand.

The result analysis was to evaluate the degree of stickiness by visually evaluating the amount of colored sand remaining in the cream application area. Measurement images were obtained using a Sony A7R camera before and after brushing off the colored sand and 1 minute later, and the degree of stickiness was compared and analyzed.

As can be seen from the results of FIG. 1, it was found that the amount of residual colored sand at the application site of the test product was significantly lower than in Comparative Examples 1 to 3 in Example 1. Therefore, it can be seen that in the feeling of use, Example 1 according to the present invention has less stickiness than Comparative Examples 1 to 3.
