Abstract
Description
[Technical Field]
[0001] The present invention relates to a composition for external use on the skin, and more specifically to a composition for external use on the skin that can form a coating film with high contractile force. [Background technology]
[0002] Aging and other factors cause the skin to lose firmness and elasticity, resulting in wrinkles and sagging. Various methods have been proposed to eliminate wrinkles and sagging skin, one of which is the use of an external skin preparation containing a film-forming agent that has the effect of lifting (lifting) the skin (Patent Document 1). Furthermore, oat kernel extract is known to have adhesive properties to the skin (Patent Document 2). [Prior art documents] [Patent documents]

[7] The composition according to any one of [1] to [6], which is a cosmetic. [Effects of the Invention]
[0007] The composition of the present invention can form a coating film that has high adhesion to the skin, high contractile force, and strength, and is therefore expected to have a skin lifting effect, making it suitable for treating wrinkles, sagging, and other skin problems associated with aging. DETAILED DESCRIPTION OF THE INVENTION
[0008] The composition for external use on skin of the present invention contains hydroxypropyl methylcellulose, oat kernel extract, and polyethylene glycol.
[0009] Hydroxypropyl methylcellulose that is usually incorporated into cosmetics can be used, and for example, one having a weight average molecular weight of 60,000 to 100,000 can be used. By using hydroxypropyl methylcellulose in combination with oat kernel extract, the cosmetic film becomes thicker and stronger. The content of hydroxypropylmethylcellulose in the composition of the present invention is preferably 0.01 to 0.2% by weight, more preferably 0.01 to 0.1% by weight, and even more preferably 0.01 to 0.05% by weight of the total composition.
[0010] Avena Sativa (Oat) Kernel Extract is a plant-derived extract containing the active ingredient Avena sativa (Oat) Kernel Extract. Sativa (Oat) seed extract. Commercially available oat kernel extracts can be used, for example, OSILIFT (containing 10% by weight of oat kernel extract) manufactured by Silab. The content of the oat grain extract in the composition of the present invention is preferably 0.008 to 0.02 wt %, more preferably 0.008 to 0.015 wt %, and even more preferably 0.01 to 0.0125 wt %, in dry weight, of the total composition.
[0011] The polyethylene glycol may be one that is typically incorporated into cosmetics, for example, one having a degree of polyoxyethylene polymerization of 6 to 400. The polyethylene glycol is preferably one or more selected from the group consisting of PEG-6, PEG-32, and PEG400, and more preferably a mixture of these three, but is not particularly limited thereto. The content of polyethylene glycol in the composition of the present invention is preferably 0.1 to 3 wt %, more preferably 0.5 to 2.5 wt %, and even more preferably 1 to 2 wt % of the total composition.
[0012] The three components of the composition of the present invention work together to form a coating film (cosmetic film) that has high adhesion to the skin, high contractile force, and strength. In particular, the three-dimensional sugar chain structure contained in the oat kernel extract molecule contributes to adhesion to the skin, and hydroxypropyl methylcellulose and polyethylene glycol form a strong film, to which the oat kernel extract imparts high contractile force. Therefore, when the composition of the present invention is applied to skin, the coating film that adheres to the skin has high contractile force and can lift the skin and reduce displacement in response to stress, so a lifting effect can be expected. Furthermore, such a coating film does not feel sticky and is comfortable to use.
[0013] Therefore, the composition of the present invention can be preferably applied to external skin preparations. The topical skin preparation is preferably in the form of a cosmetic or quasi-drug, and more preferably a skin care cosmetic, a sunscreen cosmetic, or a makeup cosmetic. The area to which the topical skin composition of the present invention is applied is not particularly limited, but is usually the face, limbs, neck, or décolleté.
[0014] Examples of dosage forms of the external skin composition include, but are not limited to, lotion dosage forms, emulsion dosage forms such as lotions and creams, oil dosage forms, gel dosage forms, packs, cleansers, and the like. The external skin composition may be either a leave-on type or a leave-off type.
