Description

Composition for nail care and nail care products using the same

The present invention relates to a composition for nail care, and more particularly, to a composition for nail care, including a sulfur source, vitamins, vegetable extract, cationic protein and oil, so that the nail can be cared for, and a nail care product using the same will be.

In general, a composition for nail care can be classified into a product that gives gloss to nails or toenails, and a product that gives a strengthening function depending on the effect and effect.

Nails and toenails are hard and thin pieces attached to the tips of fingers and toes, respectively, and the stratum corneum of the skin has changed. Since the main component of nails and toenails is a protein called keratin, it is known that increasing the protein intake speeds up the growth of nails and toenails.

Nails, including toenails and fingernails, are composed primarily of the protein keratin. Nails and toenails are living tissue. Nails form within pockets of inwardly grown skin, called the nail matrix. These areas give rise to the nail bed and are also called the root of the nail. The outer layer of the matrix contains specialized cells that produce keratin that grow as a nail plate.

In general, nails grow faster than toenails, and there are theories that it is because the nails are closer to the heart, so blood circulation is good, and there are theories that it is because a lot of stimulation is applied, but the exact basis has not been revealed. In addition, it is known that the growth rate of nails and toenails of modern people is faster than in the past.

Healthy looking nails should be smooth, curved, spotless, and free from hollows or bumps. Nails in unhealthy conditions can be very detrimental to an individual's image and, if left untreated, can lead to long-term embarrassment and pain-related chronic infections. In particular, they may be regarded as social problems and/or occupational diseases.

Repetitive and prolonged wetting and drying of nails is the single most common cause of cracking and bumps in nails. Cracking of nails is rarely caused by an internal medical disease or vitamin deficiency, nail polish removers cause onychoblastia (stratified fission), and ultimately, trauma to the fingers contributes to onycholysis.

Among the cosmetic damage to nails are breaking, splitting, fracturing, brittleness, white spots or ridges, sluggish nail growth, color and shape changes. things may be included.

As a conventional technique related to the care of nails and toenails, there is disclosed a "composition for nail care" in Korean Patent No. 10-2006949, which includes a carbodiimide-based compound; and a nail care material having a functional group capable of covalent bonding with a protein residue on the nail or toenail surface to form a covalent bond without damage to the nail or toenail to provide a semi-permanent desired nail care effect will be.

However, the conventional composition for nail care has insignificant effects, and there is a growing need for a novel composition having a higher effect.
