Description

Transparent hair cosmetic composition

The present invention relates to a hair cosmetic composition containing a high content of oil to improve hair conditioning while maintaining a transparent image.

Shampoo is a cosmetic used to keep hair clean and beautiful by removing contamination from the scalp and hair. In addition to cleaning purposes, shampoo is easy to comb, soft, smooth, shiny, reduces friction on the hair surface, prevents static electricity, protects hair It is also used for additional purposes.

Existing shampoos contain cationic polymers, cationic surfactants, silicones, etc. as conditioning agents in order to impart a conditioning effect.

In particular, the silicone component is a representative hair conditioning component widely used worldwide because of its excellent hair conditioning effect even in a small amount. There are many examples of using silicone by dispersing it in a hair cosmetic composition, and it has been mainly developed as an opaque composition. However, recently, consumers' preference for transparent products is increasing, and technologies for maintaining a transparent formulation while using silicone as in Patent Documents 1 and 2 are being developed to reflect this market trend. To make a transparent formulation containing silicone, either micro-emulsion type silicone is used or silicone with ionicity added such as silicone quaternium is used. There is a disadvantage with

In addition, in recent years, as the number of consumers who prefer products that do not contain silicone is increasing, products that provide conditioning and nutrition to hair with oil ingredients instead of silicone are increasing. The type of oil with excellent conditioning for hair has a lot of influence on the stability of the product, and there is a limit to its content in maintaining transparent properties. In the case of containing a small amount of oil in order to maintain a transparent image, there is a disadvantage in that the hair conditioning effect is lowered and the feeling of use is inhibited.

Therefore, there is an urgent need to develop a hair cosmetic that does not contain silicone and has excellent conditioning and nutrition, and which can maintain a transparent image.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hair cosmetic composition that has excellent hair conditioning and nutrition while maintaining transparency.

Accordingly, the present inventors have been conducting various studies on a silicone-free hair cosmetic composition that has been used as a conventional conditioning agent, and in a hair cosmetic composition containing a large amount of oil, a surfactant of a triester structure is included. In this case, the present invention was completed by confirming that the transparency and long-term stability of the formulation were improved.

Therefore, the present invention

at least one surfactant selected from the group consisting of anionic surfactants, amphoteric surfactants, nonionic surfactants and cationic surfactants;

Provided is a hair cosmetic composition of a transparent formulation comprising a triester-based auxiliary surfactant as an auxiliary surfactant and an oil.

Hereinafter, the configuration of the present invention will be described in detail.

The hair cosmetic composition of the present invention includes a triester-based surfactant.

In the present invention, the term "triester-based surfactant" means a surfactant containing three esters, and the triester-based surfactant includes PEG-20 glyceryltriisostearate, PEG-10 glyceryltriisostearate, polyglyceryl-2 triisostearate and sorbitan triisostearate, PEG-160 sorbitan It may be one or more surfactants selected from the group consisting of triisostearate (PEG-160 sorbitan triisostearate), trimethylolpropane triisostearate and isopropyl titanium triisostearate, Any surfactant having a triester structure may be included.

In the present invention, a triester-based surfactant may be used as an auxiliary surfactant. The auxiliary surfactant may solubilize an oil component that cannot be solubilized by the main surfactant, thereby imparting transparency to the formulation. The triester-based surfactant may be included in an amount of 5 to 350 parts by weight based on 100% by weight of the total oil, preferably 10 to 300 parts by weight, more preferably 50 to 250 parts by weight, even more preferably 100 to 200 parts by weight. , more preferably 130 to 180 parts by weight may be included.

In addition, the triester-based surfactant may be included in an amount of 0.1 to 30% by weight relative to 100% by weight of the total composition, preferably 0.1 to 20% by weight, 0.2 to 15% by weight, 0.5 to 10% by weight, 1 to 5% by weight may be included as When the content of the triester-based surfactant is less than 0.1% by weight, oil solubilization power is lowered, and when the content exceeds 30% by weight, transparency is impaired due to the low HLB characteristics of the surfactant itself. Therefore, it is possible to provide a hair cosmetic composition capable of maintaining a transparent phase even if the composition contains a large amount of oil in the content range of the triester-based surfactant as described above.

The composition according to the present invention contains at least one surfactant selected from the group consisting of an anionic surfactant, an amphoteric surfactant, a nonionic surfactant, and a cationic surfactant as the main surfactant, as well as a triester-based surfactant as an auxiliary surfactant. includes

The anionic surfactant is, for example, sodium lauryl sulfate, ammonium lauryl sulfate, magnesium lauryl sulfate, triethanolamine lauryl sulfate, sodium polyoxyethylene lauryl sulfate, polyoxyethylene lauryl ammonium sulfate, disodium laureth sulfosuccinate nate and potassium cocoyl glycinate may include at least one selected from the group consisting of, preferably polyoxyethylene lauryl sodium sulfate. The anionic surfactant may be used for cleaning various wastes in the composition.

The amphoteric surfactant may include, for example, at least one selected from the group consisting of cocamide propyl betaine, lauryl hydroxy sultaine and lauramido propyl betaine, but is not limited thereto. The amphoteric surfactant may be included in the composition and used for a softening effect on hair, an antistatic effect, and the like.

The nonionic surfactant is, for example, lauryldimethylamine oxide, palm oil alkyldimethylamine oxide, lauryl acid diethanolamide, palm oil fatty acid diethanolamide, palm oil fatty acid monoethanolamide, polyoxyethylene lauryl ether, and polyoxyethylene nonylphenyl. It may include one or more selected from the group consisting of ether, but is not limited thereto. The nonionic surfactant may be included for increasing the viscosity of the composition, an auxiliary effect of cleaning, and solubilizing the oil.

The cationic surfactant may include at least one selected from the group consisting of behentrimonium chloride, steatrimonium chloride, ceteatrimonium chloride and stearamidopropyldimethylamine, but is not limited thereto. The cationic surfactant has excellent adsorption to hair, and thus may be used to prevent static electricity.

In the present invention, the type and content of the main surfactant is not particularly limited, and those skilled in the art can appropriately adjust the type and content of the surfactant commonly used. For example, when the composition of the present invention is used as a shampoo or conditioner (rinse), which is the most common product, the commonly used surfactants as described above may be included alone or in combination, and 5 to 50% by weight relative to 100% by weight of the total composition % may be included.

In addition, the composition according to the invention comprises a large amount of oil.

In the present invention, the oil can reduce the stiffness of the hair in wet and dry conditions to facilitate combing, provide a conditioning effect to the hair, and can be used to improve damage by supplying nutrients to damaged hair. . The oil may include one or more oils selected from the group consisting of natural oils, ester oils, and ether oils, but is not limited thereto.

The natural oil may be, for example, olive oil, macadamia seed oil, jojoba seed oil, argan tree kernel oil or camellia oil, preferably olive oil. Examples of the ester-based oil and the ether-based oil include dicaprylryl ether, PPG-3 caprylryl ether, and PPG-3 myristyl ether. ), di-C12-13-alkyl malate or caprylic/capric triglyceride, preferably di-C12-13-alkyl It may be a di-C12-13-alkyl malate.

In the present invention, the oil may be included in an amount of 0.5 to 10% by weight relative to 100% by weight of the total composition, preferably 1 to 7% by weight, more preferably 1.5 to 6% by weight, even more preferably 2 to 5% by weight may be included. When the content of the oil is less than 0.5% by weight, the hair conditioning effect from the oil may be insufficient, and when the content of the oil exceeds 10% by weight, the foaming power of the surfactant is lowered to decrease the cleaning power and the transparency of the composition There is a problem in that it is difficult to maintain the award. The composition according to the present invention contains oil in the above content range so that the hair conditioning effect and nutritional feeling are excellent while maintaining the transparent phase.

The composition may additionally include a cationic polymer in order to impart a conditioning effect, preferably polyquaternium-10.

Accordingly, the present invention can provide a hair cosmetic composition that contains a large amount of oil to have excellent hair conditioning effect and nutritional feeling while maintaining transparency.
