Description

Hair cosmetic composition {HAIR COSMETIC COMPOSITION}

This description relates to hair cosmetic compositions.

Generally, human hair consists of three layers: cuticle layer, cortex, and medulla. The cuticle layer is the outermost layer that surrounds and protects the cortex. The undamaged cuticle of healthy hair has a smooth surface, refracts light, and reduces friction between hairs.

Hair is easily affected by the external environment, and is specifically damaged by factors such as cold and dry wind, indoor heating, excessive combing, stress, lack of nutrition, and lack of sleep. In addition, as modern people have recently recognized hair as a fashion, there has been an increase in the number of cases of frequent hair treatments such as dyeing, perming, and bleaching, excessive use of hair beauty products, or use of hair dryers for long periods of time, resulting in hair damage. Occurs frequently.

When hair is damaged by various physical, chemical, or environmental factors, it causes loss of the cuticle layer of the hair, and the proteins and lipids inside the hair are eluted, causing the hair to become rough, lose luster, and increase friction, causing the hair to easily tangle. Easily cut or split ends occur. In addition, problems such as loss of volume or thinning of hair as hair sags due to loss of elasticity also occur. In addition, damaged hair is difficult to repair, so it needs to be carefully managed on a daily basis.

Therefore, consumers' demands and preferences for conditioning (hair condition improvement) products that can maintain shiny and elastic hair are increasing day by day.

Existing conditioning products contain cationic surfactants or cationic polymers to improve the appearance and feel of the hair and achieve a lasting effect. Specifically, they are adsorbed to the anionic hair surface due to damage and improve the hair surface, thereby improving the hair condition. It improves the condition and prevents future hair damage and static electricity generation, making it easier to manage both wet and dry hair.

However, current conditioning products using cationic substances only act on the hair surface, so they lose their effectiveness after hair washing. In particular, in the case of thinned or rough hair, the strength inside the hair is greatly reduced, so it is difficult to obtain a sufficient effect through hair surface modification alone.

Accordingly, there have been several attempts to improve hair condition and durability by varying the composition of cationic surfactants, higher alcohols, oils, etc. or developing new compounds.

For example, an attempt is made to maximize sustainability while providing the characteristics of healthy hair by hydrophobicizing the hair surface by including a compound with a reactive moiety capable of forming a covalent bond with a specific moiety of the hair in the treatment composition. There was.

In this case, it may have some efficacy in improving hair condition, but the effect is not sufficient, and its application is limited or the manufacturing process is difficult due to concerns about human safety, processing stability, etc.

As another example, there was an attempt to develop a mousse-type hair conditioner, but the sprayed foam did not break down easily, so the spreadability on the hair was reduced, and the elasticity of the foam was weak, so it had the disadvantage of leaving a damp feeling after applying it to the hair. .

Therefore, there is a greater need for the development of new hair care compositions that exhibit excellent conditioning effects and durability while also providing excellent applicability to hair and feeling of use.

One embodiment is intended to provide a leave-on type aerosol hair cosmetic composition in the form of a foam that has a refreshing feel and excellent spreadability, leaving hair soft and shiny for a long time.

The amine compound may be included in an amount of 1% by weight or more based on the total amount of the hair cosmetic composition.

The C16 alcohol compound may be included in an amount of 100 to 300 parts by weight based on 100 parts by weight of the amine compound.

The C2 to C6 alcohol compound may be included in an amount of 500 to 1000 parts by weight based on 100 parts by weight of the amine compound.

The amine compound, C16 alcohol compound, and C2 to C6 alcohol compound may be included in a weight ratio of 1:1 to 3:5 to 10.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

In this specification, “conditioning effect” refers to recovery of damaged hair or prevention of damage to healthy hair. Specifically, it strengthens hair by thickening hair or improving tensile strength, and adds softness, moisture, smoothness, and elasticity to hair. , which means maintaining healthy hair by adding volume.

In this specification, when a part of a layer, membrane, region, plate, etc. is said to be “on” another part, this includes not only the case where it is “right on” the other part, but also the case where there is another part in between. Conversely, when a part is said to be “right on top” of another part, it means that there is no other part in between.

Hereinafter, a hair cosmetic composition according to one embodiment will be described.

Hair treatments, oils, creams, etc. are generally used to give softness and shine to damaged hair. However, since hair treatments are washed off, the softness and shine do not last long, and oils and creams have excellent softness and shine, but have the disadvantage of leaving a damp and sticky feeling on the hands and hair for a long time. In addition, similar types of products developed previously (mousse-type hair conditioner; aerosol cosmetic composition) have the disadvantage that the foam does not break down easily, so they do not spread well on the hair, and a wet, wet feeling is felt after being applied to the hair.

However, one embodiment is a foam-type leave-on hair containing as essential components an amine compound containing an amide linkage and an amine group at either end, a monobasic acid compound containing a hydroxy group, a C16 alcohol compound, and a C2 to C6 alcohol compound. It is a care composition (hair cosmetic composition) that maintains hair softness and shine for a long time with a refreshing feeling of use and excellent spreadability compared to leave-on products such as existing oils or creams and similar types developed previously (mousse-type hair conditioner; aerosol cosmetic composition). There is a characteristic.

The amine compound containing the amide linkage group and an amine group at either end may be included in an amount of 1% by weight or more, for example, 1% by weight to 3% by weight, based on the total amount of the hair cosmetic composition according to one embodiment.

If the amine compound is included in less than 1% by weight based on the total amount of the hair cosmetic composition according to one embodiment, the amount of the amine compound is relatively too small, so the sustainability of hair softness is reduced and it is difficult to feel a refreshing feeling after use. In addition, if the amine compound is included in more than 3% by weight based on the total amount of the hair cosmetic composition according to one embodiment, it is undesirable because skin irritation problems may occur.

For example, the amine compound, C16 alcohol compound, and C2 to C6 alcohol compound may be included in a weight ratio of 1:1 to 3:5 to 10. When the amine compound, C16 alcohol compound, and C2 to C6 alcohol compound have the above weight ratio range, it is possible to maintain softness on the hair while maintaining excellent spreadability, foam retention, and refreshing sensation on the hair.

For example, the amine compound may be represented by the following formula (1).

[Formula 1]

In Formula 1,

R ¹ to R ³ are each independently a substituted or unsubstituted C1 to C20 alkyl group,

L ¹ is a substituted or unsubstituted C1 to C20 alkylene group,

n is an integer from 1 to 20.

For example, in Formula 1, R ¹ may be a substituted or unsubstituted C11 to C20 alkyl group, R ² and R ³ may each independently be a substituted or unsubstituted C1 to C10 alkyl group, and L ¹ may be a substituted or unsubstituted C1 to C10 alkyl group. It may be a ringed C1 to C10 alkylene group, and n may be an integer of 1 to 10.

When using the compound represented by Formula 1 as the amine compound, the sustainability of hair softness, the spreadability of the composition on the hair, the elasticity of the foam produced from the composition, and the freshness (sensory) are improved compared to the case of using amine compounds of other structures. Everyone can be excellent.

The hydroxy group-containing monobasic acid compound may be represented, for example, by the following formula (2).

[Formula 2]

In Formula 2,

R ⁴ is an unsubstituted C1 to C20 alkyl group.

For example, in Formula 2, R ⁴ may be an unsubstituted C1 to C10 alkyl group, such as an unsubstituted C1 to C5 alkyl group.

In Formula 2, the carbon atom directly bonded to the hydroxy group (excluding the hydroxy group constituting the carboxyl group) may have an R configuration or an S configuration. That is, Chemical Formula 2 may exist as an optical isomer, in a racemic mixture, or in any one configuration.

When the compound represented by Formula 2 is used as the monobasic acid, both the sustainability of hair softness and the elasticity of the foam produced from the composition can be superior to those when monobasic acid compounds of other structures are used.

The amine compound and monobasic acid compound may be included in a molar ratio of 1:1. The amine compound and the monobasic acid compound must be included in the molar ratio so that the amine compound can be neutralized by the monobasic acid compound and be more soluble in solvents such as deionized water, and further serve as a surfactant and hair conditioning agent. can do.

The C16 alcohol compound may be included in an amount of 100 to 300 parts by weight based on 100 parts by weight of the amine compound. If the C16 alcohol compound is included in an amount of less than 100 parts by weight compared to 100 parts by weight of the amine compound, the sustainability of hair softness and the spreadability of the composition on the hair may be reduced, which may be undesirable. If it is included in more than 300 parts by weight, the elasticity and freshness (sensory) of the foam produced from the composition may be reduced, which may be undesirable.

For example, the C16 alcohol compound may be represented by the following formula (3).

[Formula 3]

In Formula 3 above,

R ⁵ is an unsubstituted C16 alkyl group.

When the compound represented by Chemical Formula 3 is used as the C16 alcohol compound, both the sustainability of hair softness and the spreadability of the composition on hair may be superior to those when C16 alcohol compounds of other structures are used.

The C2 to C6 alcohol compound may be included in an amount of 500 to 1000 parts by weight based on 100 parts by weight of the amine compound. If the C2 to C6 alcohol compound is included in an amount of less than 500 parts by weight compared to 100 parts by weight of the amine compound, the spreadability and freshness (sensory) of the composition on the hair may be reduced, which may be undesirable, and the C2 to C6 alcohol compound may be undesirable due to the amine compound. If it is included in more than 1000 parts by weight compared to 100 parts by weight of the compound, it may be undesirable because the sustainability of hair softness and the elasticity of the foam produced from the composition may decrease.

For example, the C2 to C6 alcohol compound may be represented by the following formula (4).

[Formula 4]

In Formula 4 above,

R ⁶ is an unsubstituted C2 to C6 alkyl group.
