Description

Sulfate-free cosmetic composition for improving hair or scalp {SULFATE-FREE COSMETIC COMPOSITION FOR IMPROVING CONDITION OF HAIR OR SCALP}

The present invention relates to a sulfate-free cosmetic composition for improving hair or scalp.

Specifically, the present invention is sulfate-free, including functional substances including lemon peel powder, gardenia peel powder, green tea extract, pomegranate extract, Eoseongcho extract, mulberry extract, and burdock extract, while being mild to the skin, to reduce scalp itchiness and dandruff. By reducing, it relates to a cosmetic composition that improves the condition of the hair or scalp.

In the modern society that values beauty, hair dyes and perm agents are used for cosmetic purposes or individuality expressions, and thus damage to the hair and scalp is emerging as a serious problem. In addition, various harmful substances are attached to or absorbed by the hair or scalp due to pollution such as factories and automobiles, thereby further intensifying damage to the hair and scalp.

In this case, itching of the scalp is intensified, and dandruff of the scalp is intensified due to water imbalance, decreased antibacterial ability, etc., and the overall scalp condition is deteriorated. In addition, as the scalp is not healthy, the hair growing from the scalp becomes thinner or easily damaged, and in severe cases, it leads to hair loss, causing serious mental pain.

Accordingly, in recent years, in order to improve the condition of the hair or scalp, the development of cosmetic compositions such as shampoos, rinses, treatments, and scalp tonic (hair tonic) including various extracts and functional ingredients has been actively developed.

For example, in Korean Patent Registration No. 10-2080412, a shampoo for improving scalp and inhibiting hair loss, including a mixed extract of graviola, rhubarb, seokchangpo, manhyeongja and wolfberry, silk amino acid, essential oil, surfactant, etc. It is starting. In addition, Korean Patent Laid-Open No. 10-2007-0103341 discloses a shampoo composition for scalp protection, including a mushroom, an extract of health, and a sulfate-based surfactant.

On the other hand, as in the prior art disclosed in the above patent, in the case of including a natural substance itself, or including an extract or powder of a natural substance, the ingredients are not stably dispersed or dissolved in the cosmetic composition formulation, and over time Accordingly, there was a problem of forming a precipitate or discoloration in the formulation.

Typically, in order to solve the above problems, a sulfate-based surfactant and various preservatives are added, but the sulfate-based surfactant severely irritates the hair and scalp, causing scalp inflammation, itchiness, and dandruff. In severe cases, there is a problem of causing hair loss along with hair damage.

Accordingly, a cosmetic composition for improving hair or scalp that contains a natural substance itself or contains an extract or powder of a natural substance, which has excellent scalp condition improvement effect, and can maintain a stable formulation for a long time without including a sulfate-based surfactant. Development is required.
