[0001] Transparent conditioning shampoo composition [0002]

The present invention relates to a transparent conditioning shampoo composition, and more particularly, to a transparent conditioning shampoo composition which is excellent in washing power and bubble power, which is the original function of shampoo, and which maintains transparency stably and is excellent in a hair conditioning condition in a wet state and a dry state.

Transparent shampoo is a clean and mild image that is preferred as an infant or shampoo for children. It provides aesthetic merits with its beautiful appearance. However, since the formulation is opaque when using a conventional hair conditioning agent, the conditioning components to be added are limited, and the product performance is also unsatisfactory And the amount of foam is insufficient, so that the function as a shampoo is insufficient.

Conditioning of hair is primarily provided through the use of raw materials such as cationic surfactants, cationic polymers, silicone conditioning agents, hydrocarbon oils and fatty alcohols. However, oil and silicone components are opaque and thus not applicable to transparent formulations. In addition, cationic surfactants, cationic polymers, hydrocarbon oils and fatty alcohols also form complexes with anionic surfactants used for cleaning, which makes the appearance opaque and hinders bubbles, making it difficult to use as a main conditioning agent in transparent formulations.

Korean Patent No. 1990-006825 discloses a technique for providing a conditioning effect by microemulsifying silicone oil with lanolin alcohol and an emulsifier. However, when these components are used, the foaming power is largely lowered and the conditioning effect is insignificant. U.S. Patent No. 5,145,607 proposes a transparent conditioning shampoo as a technique of excluding oil, silicone and the like and adding a cationic polymer and a cationic surfactant to the anionic surfactant prescription, but the cationic polymer is sticky or build- And the cationic surfactant is still inadequate in terms of conditioning effect because of its low temperature stability, transparency and irritation, which makes it difficult to overuse the cationic surfactant. U.S. Patent No. 5,990,059 uses anionic surfactants and cationic guar gum derivatives and microemulsions silicone oil to achieve conditioning while maintaining a clear formulation. However, cationic guar gum derivatives do not have excellent low temperature stability, and if used excessively in order to achieve a conditioning effect, they may be sticky or build up. In addition, even in the case of silicone microemulsion, it is difficult to achieve a sufficient conditioning effect, and the consumer of severe damaged hair still has a disadvantage that the hair tends to be clogged when used. Korean Patent No. 10-0564223 proposes a transparent conditioning shampoo using a zwitterionic or nonionic surfactant and a cationic polymer as a conditioning agent. However, since an anionic surfactant is not used, the basic property of the shampoo is excellent in foamability and cleaning power Can not do it.

It is an object of the present invention to provide a transparent conditioning shampoo composition which is excellent in washing power and foaming power, which is the original function of shampoo, and which is stably maintained in transparency, and has excellent hair conditioning effect in a wet state and a dry state.

According to an aspect of the present invention,

and x, y and z are an integer of 2 to 200.)

The mass ratio of the polyethylene glycol-alkyl glyceride to the silicon microemulsion may be from 10: 1 to 1:10.

The particle size of the silicon microemulsion may be 0.05 m or less.

The anionic surfactant may be an alkylsulfate represented by the following formula 4 or an alkyl ether sulfate represented by the following formula 5:

The shampoo composition of the present invention can keep the formulation stable and transparency stably.

The shampoo composition of the present invention is transparent, so that the appearance of the shampoo composition is excellent, and a clean and mild image can be obtained.

The shampoo composition of the present invention is excellent in cleaning power and foaming power.

The shampoo composition of the present invention exhibits excellent conditioning effect on wet and dry hair.

Hereinafter, the present invention will be described in detail so as to be easily carried out by those skilled in the art.

The conditioning shampoo composition of the present invention comprises an anionic surfactant; Silicone microemulsions; And polyethylene glycol-alkyl glycerides. The shampoo composition of the present invention is excellent in cleaning power and bubble power, which are functions inherent in shampoo, and has excellent appearance and transparency.

The polyethylene glycol-alkyl glycerides serve to increase the conditioning effect of the shampoo composition of the present invention when used in combination with the silicone microemulsion while maintaining transparency stably.

The polyethylene glycol-alkyl glyceride may be contained in an amount of 0.1 to 10 parts by weight, preferably 0.1 to 5 parts by weight. If the amount is less than 0.1 part by weight, the conditioning effect may be deteriorated. If the amount is more than 10 parts by weight, the bubble strength may be lowered.

The polyethylene glycol-alkyl glycerides may be represented by any one of the following formulas (1) to (3):

[Chemical Formula 1]

(2)

(3)

In the general formulas (1) to (3), R ₁ to R ₃ are the same or different and each independently represents an alkyl group having 10 to 25 carbon atoms, and x, y and z are integers from 2 to 200.

The polyethylene glycol-alkyl glycerides which may be represented by any one of formulas (1) to (3) are structures in which glycerides represented by any one of the following formulas (a) to (c) are combined with polyethylene glycol represented by the following formula (d).

(A)

[Formula b]

(C)

In the above formulas (a) to (c), R ₁ to R ₃ may be the same or different and each independently an alkyl group having 10 to 25 carbon atoms.

[Chemical formula d]

In the above formula (d), n may be an integer of 2 to 200, preferably 10 to 60. [

Specific examples of the polyethylene glycol-alkyl glycerides include PEG-n Almond Glyceride, PEG-n Caprylic / Capric Glyceride, PEG-n Palm Kernel Glyceride, PEG-n Macadamia Glyceride, PEG-n Sunflower Glyceride, , PEG-n Palm Glyceride, and the like, but are not limited thereto.

The silicone microemulsion serves to raise the conditioning effect. The silicon microemulsion is made into a microemulsion by reducing the particle size of silicon, which is an oil component, and can maintain transparency.

The silicon microemulsion may be included in an amount of 0.1 to 2.0 parts by weight. When the amount is less than 0.1 part by weight, the increase of the conditioning effect is insignificant. When the amount is more than 2.0 parts by weight, transparency is decreased and a build-up phenomenon may occur during long-term use.

The particle size of the silicon microemulsion may be 0.05 m or less. In order to stabilize silicone in a shampoo formulation, it is used by emulsification. However, when the particle size of the silicone microemulsion is more than 0.05 mu m, it is difficult to form a transparent formulation. Therefore, it is preferable to use a material having a particle size of 0.05 mu m or less.

Specific examples of the silicone microemulsion include dimethicone or dimethicone microemulsion and amodimicicon microemulsion having a particle size of 0.05 mu m or less.

The mass ratio of the polyethylene glycol-alkyl glyceride to the silicon microemulsion may be from 10: 1 to 1:10. The polyethylene glycol-alkyl glyceride has an advantage that it can stably maintain transparency, but when it is used alone, it lacks a conditioning effect. However, when the silicone microemulsion is used together with the silicone microemulsion in the above-mentioned ratio range, it is possible to impart an excellent conditioning effect to hair while maintaining transparency stably.

The anionic surfactant serves to impart cleaning power and foaming power to the shampoo composition of the present invention.

The anionic surfactant may be contained in an amount of 3 to 50 parts by weight, and preferably 5 to 30 parts by weight. If it is contained in an amount of less than 3 parts by weight, the washing power and the foaming power are decreased. If the amount is more than 50 parts by weight, the conditioning effect may be hindered.

The anionic surfactant may be an alkylsulfate represented by the following formula 4 or an alkyl ether sulfate represented by the following formula 5:

[Chemical Formula 4]

R ₄ OSO ₃ M

(In the formula 4,

R < ₄ > is alkyl or alkenyl having 8 to 18 carbon atoms,

M is a metal cation such as ammonium, sodium or potassium and is selected from water-soluble cations.)

[Chemical Formula 5]

R ₅ O (C ₂ H ₄ O) x SO ₃ M

(In the above formula (5)

R < ₅ > is alkyl or alkenyl having 8 to 18 carbon atoms,

x is an integer of 1 to 10,

M is a metal cation such as ammonium, sodium or potassium and is selected from water-soluble cations.)

Specific examples of the anionic surfactant include, but are not limited to, ammonium lauryl sulfate, ammonium laureth sulfate, sodium lauryl sulfate, sodium laureth sulfate, and the like.

As shown in Tables 3 and 4, the shampoo compositions of Examples 1 to 9 containing both silicone microemulsion and polyethylene glycol-alkyl glyceride were prepared by using silicone microemulsion or polyethylene glycol-alkyl glyceride alone And exhibited superior foaming power and foam stability when compared with the shampoo compositions of Comparative Examples 1 to 5. In Comparative Example 8, the silicone microemulsion and the polyethylene glycol-alkyl glyceride were contained in an excessive amount and the foaming power was lowered. In addition, since the shampoo composition of Comparative Example 9 had almost the same foaming power as the example, it can be seen that the particle size of the silicone microemulsion does not greatly affect the foaming power.

< Experimental Example  2> Coaseurate Formability  evaluation

Assessment of the conditioning effect was made using a coacervate formability assessment known in the art as a method for evaluating the conditioning effect of a shampoo universally. Coacervate serves to deliver the silicone emulsion to the hair, thereby increasing the hair conditioning effect.

100 ml of the 10% dilution of the transparent shampoo compositions of Examples 1 to 9 and Comparative Examples 1 to 9 was centrifuged (3,000 rpm, 30 minutes) to measure the amount of precipitated coacervate. The results are shown in Tables 5 and 6 .

As shown in Tables 5 and 6, the shampoo compositions of Examples 1 to 9, which include both silicone microemulsion and polyethylene glycol-alkyl glyceride according to the present invention, are characterized in that silicone microemulsion and polyethylene glycol-alkyl glyceride It was confirmed that the shampoo compositions of Comparative Examples 1 to 5 alone had a superior coacervate forming ability. In Comparative Example 6, the addition amount of the silicone microemulsion was lower than that of the polyethylene glycol-alkyl glyceride, so that the formation ability of the coacervate was lowered.

< Experimental Example  3> Consumer Feeling  And conditioning effects

In order to evaluate the feel and conditioning effect of the transparent shampoo compositions prepared in the above Examples and Comparative Examples, 200 women aged 25 to 40 years with relatively damaged hair due to dyeing and perming were selected, And the evaluation items shown in Table 8 were tested.

According to Tables 7 and 8, the transparent shampoo compositions of Examples 1 to 9, in which silicon microemulsion and polyethylene glycol-alkyl glyceride were used in parallel, were evaluated for the sensation of hair, corrective sensation, smoothness, build- The shampoo compositions of Comparative Examples 1 to 8 were evaluated to be superior to the shampoo compositions. The shampoo composition of Comparative Example 9 was rated on the same level as the shampoo composition of the Examples in terms of hair feeling, straight feeling, softness, build-up phenomenon, and softness after drying. That is, the particle size of the silicone microemulsion does not appear to have a great influence on feel or conditioning.

< Experimental Example  4> Evaluation of transparency

The transparency of the shampoo prepared in Examples 1 to 9 and Comparative Examples 1 to 9 was evaluated by a turbidimeter. Turbidimeters are 75% transmittance at 600 nm using a UV spectrophotometer. The transparency measurement results are shown in Tables 9 and 10 below.

According to Tables 9 and 10, the shampoo compositions of Examples 1 to 9 using silicon microemulsion and polyethylene glycol-alkyl glyceride in combination showed excellent transparency. In addition, the shampoo compositions of Comparative Examples 1 to 7, in which silicone microemulsion or polyethylene glycol-alkyl glyceride alone or in small quantities, exhibited the same level of transparency as the examples. However, it was confirmed that the transparency was not good in Comparative Example 8 using silicone microemulsion and polyethylene glycol-alkyl glyceride in an excess amount exceeding the respective claims, and Comparative Example 9 using dimethicone emulsion having a particle size of 0.05 m or more.

As described above, the conditioning shampoo composition of the present invention is excellent in cleaning power and bubble power, which are functions inherent in shampoo, while maintaining transparency stably, and is also excellent in conditioning effect.
