Description

Technical Field [0001] The present invention relates to a cosmetic composition for enhancing skin moisturizing effect containing a natural plant extract and PHA,

The present invention (Disclosure) relates to a cosmetic composition which simultaneously contains a natural plant extract and PHA to enhance skin moisturizing power.

Herein, the background art relating to the present invention is provided, and they are not necessarily referred to as known arts.

Human skin contains about 15-20% moisture, and the human body contains about 70-75% water. The skin protects our body from various external stimuli and also acts as a barrier to the moisture inside our bodies not coming out.

In the field of cosmetics, studies have been carried out for a long time to prevent and improve skin aging by preventing moisture loss from the skin and compensating for lost skin moisture, and many related materials have been applied to the products.

A variety of moisturizers, such as polyol, sugar, and polymer ingredients, have been applied to cosmetics as typical ingredients of cosmetic ingredients. By strengthening the function of skin barrier by using ceramide, fatty acid, and cholesterol, which are skin components, Materials have also been applied to cosmetics.

In addition, natural plant extracts are also used as cosmetic raw materials to enhance skin moisturizing or skin barrier function.

Experimental Example  1: Moisturizing effect of formulations containing plant extracts and PHA

The clinical moisturizing effect and the sustaining ability of the cosmetic composition of the present invention were measured as follows. Through the questionnaire, each of the formulations was applied to the upper arm and upper thigh of 30 healthy adult men and women who feel dry skin twice a day for 2 weeks. The moisturizing effect was evaluated by evaluating the improvement rate (%) of the skin electrical conductivity according to the moisture amount of the skin using a Corneometer CM 820 (Corage + Khazaka, Germany) after the start and end of the actual use test. The experimental results are shown in Table 2 below.
