Description

TECHNICAL FIELD The present invention relates to a scalp and a hair-containing pseudoceramide composition containing pseudoceramide,

The present invention relates to a composition for scalp and hair moisturizing comprising pseudoceramide and peony root extract, and provides a composition for scalp and hair moisturizing which has a low stimulus and high moisture-holding power.

The scalp and hair of the human body are susceptible to damage not only by ordinary stimuli such as shampoos and dryers but also by physicochemical stimuli such as dyeing, perming and ultraviolet rays aiming at the beauty of hair. The damaged scalp and hair are more easily removed from the scalp by the shampoo, which causes the hair to become dry and unglamorous and become more sensitive to external stimuli.

The barrier function of the stratum corneum is severely deteriorated by the dried scalp, and when the barrier function of the scalp deteriorates, scalp troubles such as itchiness, dandruff and flare become more likely to occur. Scalp trouble is directly linked to the health of the hair. If the scalp is not healthy, the hair may lose its elasticity and gloss, and furthermore may cause hair loss, structural deformations of the hair, and the like. Conventionally, it has been attempted to improve the scalp trouble by directly applying the composition for scalp moisturizing on the scalp. However, since the scalp has a lot of thick and long hair and has a high density of hair as compared with the skin of other areas, , There is a problem that troubles are caused in the scalp by cosmetics which are put on the hair or are not evenly applied due to the hair. In addition, since the scalp has a lot of sebum and a wide pore, it is difficult for the moisturizing component to penetrate sufficiently as compared with the skin of other areas, and the hair is easily greased and bundled by the cosmetic for scalp.

Conventional scalp compositions have little viscosity or cream type, and when the viscosity is too low, it is difficult to apply the composition uniformly to the scalp due to the inconvenience that the product flows down along the scalp. If the viscosity is too high, It is difficult to apply uniformly, and it may give a feeling of unfavorable feeling to the scalp or cause troubles. In order to solve such problems, a spray type low viscosity scalp composition has been proposed. However, there has been a problem that the hair is wetted or the moisturizing feeling is not given at the time of coating, and since the low viscosity formulations contain various moisturizing ingredients, And the like.

The recently developed pseudoceramide PC-AKS (International Patent Publication No. WO2016-076520) has a greatly improved solubility and thus can be used relatively freely in a cosmetic composition. However, when applied to conventional scalp moisturizing compositions, pseudoceramide is unstable in the formulation , There is a feeling of use feeling such as not being neat and easily greasy.

The present invention provides hypo hypodermic scalp and hair moisturizing composition excellent in scalp moisturizing and exfoliation improvement, including pseudoceramide and peony root extract, and is useful as a cosmetic composition suitable for use in scalp and hair including polysorbate and ethylhexyl stearate To provide a composition for scalp and hair moisturizing.

[Chemical Formula 1]

(Wherein R < ₁ > is a single bond straight chain alkyl group having a carbon number of 18 or a straight chain alkenyl group containing at least one double bond, and R < ₂ > is a straight chain alkyl group having from 12 to 22 carbon atoms,

The pseudoceramide represented by Formula 1 is characterized in that the structure of the compound is designed asymmetrically and the solubility is greatly improved and that the compound is prepared by a one-step reaction of succinic acid derivative and alkenylamine. More specifically, it is prepared by ring-opening reaction of an anhydride-sultone derivative and alkenylamine. When such a production method is applied, a pseudoceramide having a high skin-affinity and a good moisture-holding ability is prepared can do. The pseudoceramide expressed by the above formula (1) is similar to the sphingosine-based structure of the ceramide present in the hair cuticle and has a functionally similar effect.

According to an example of the present invention, an example of the compound having a pseudoceramide structure of the above formula (1) is the compound of the formula (2).

(2)

In the above formula, the amine was obtained through ring-opening reaction with oleic amines and anhydrous succinic acid having at least one double bond having 12 carbon atoms.

The pseudoceramide may be contained in an amount of 0.01 to 1.5% by weight based on the total weight of the composition for scalp and hair moisturizing. If it is less than 0.01% by weight, it is hard to expect the effect of improving the scalp and hair by moisturizing. If it exceeds 1.5% by weight, it may not feel crispy when applied to scalp and hair, There is a problem of being uneasy.

In the composition for scalp and hair moisturizing, the total amount of nonionic monoesters composed of at least one of polysorbate 60 and polysorbate 40 may be 0.5 or more by weight relative to the pseudoceramide. When the weight ratio is less than 0.5, there is a problem that the emulsion stability of the pseudoceramide is deteriorated and the appearance stability of the composition becomes unstable.

Peony root extract

The composition for scalp and hair moisturizing according to the present invention comprises peony root extract.

Peony root extract refers to a natural ingredient extracted from the root of a peony. The peony is also called Mokan (牧 丹), and its height is 2m. The branch is thick and has no hairs. The leaves of the peony are in three layers, the small leaves are ovate, split into 2 ~ 5 pieces, the leaves have no hair, the back side has fine hairs, The extract of the peony root has antioxidative effect, anti-inflammatory effect, skin aging prevention effect, melanin formation inhibitory effect, moisturizing effect and the like.

The peony root extract contained in the composition of the present invention may be dissolved in various extraction solvents such as water, anhydrous or lower alcohol having 1 to 4 carbon atoms (methanol, ethanol, propanol, butanol), acetone, ethyl acetate, chloroform, , 3-butylene glycol, and butyl acetate. For example, the extract of the present invention may be obtained using water and ethanol.

The peony root extract may be included in an amount of 0.05 to 5% by weight based on the total weight of the composition for scalp and hair moisturizing. When the amount is less than 0.05% by weight, it is difficult to expect an effect of alleviating skin irritation and calming hair and scalp, and when the amount is more than 5% by weight, the feeling of use tends to be deteriorated.

The composition for scalp and hair moisturizing according to the present invention comprises at least one nonionic monoester selected from polysorbate 60 and polysorbate 40.

The polysorbate 60 and the polysorbate 40 are polyoxyethylene higher aliphatic alcohols having no stimuli and having ethylene oxide bonded to a sorbitan fatty acid ester, which is a kind of nonionic monoester. The polysorbate 60 and the polysorbate 40 may be contained in an amount of 0.1 to 1% by weight based on the total weight of the composition. When the amount is less than 0.1% by weight, the formulation stability may be low, and when exceeding 1% There is a problem that the feel is deteriorated.

The composition for scalp and hair moisturizing according to the present invention includes ethylhexyl stearate.
