Description

Hair cosmetic composition having a lamellar liquid crystal structure by using glucose-based surfactants by using a lecithin-based surfactant

The present invention relates to a cosmetic composition for hair with increased durability of hair softness, and more particularly, by forming a lamellar liquid crystal structure using a lecithin-based surfactant, it is easy to adsorb to the hair surface, and the durability of hair softness is increased, It relates to a cosmetic composition for hair with enhanced scent persistence.

In order to make the hair softer, silicone oil with excellent spreadability is applied to the existing hair products. However, since damaged hair is in a state of charge, a non-polar material such as silicone is not well adsorbed to the damaged hair, and thus, satisfactory results in imparting desired properties to the hair have not been achieved.

On the other hand, in the cosmetic field, when a composition for forming a multi-layered lamellar structure is prepared and used, it is known that such a composition plays an important role in skin moisturizing and barrier function. This is an emulsified form of a valve structure composed of phospholipids, and is due to the structural characteristics of the lamellar structure in which the oil layer and the aqueous layer are sequentially stacked blocks.

When the liquid crystal phase is formed, the viscosity of the emulsified particles increases and the structure becomes stable, and the lamellar structure thus formed acts as a barrier with high moisturizing power due to the characteristics of the lamellar structure compared to the general O/W and W/O structures.

Usually, the emulsion structure is an O/W type where the trauma is water, and when applied, the moisture that is the trauma is evaporated, the balance of the emulsion is broken and its function is significantly reduced. In addition, the W/O phase is suitable to solve this problem, but has a disadvantage in that the feeling of use is poor. On the other hand, the lamellar structure has a good structure that can solve all of these because the oil layer and the aqueous layer are multi-layered.

The present invention relates to a higher aliphatic alcohol; and a lecithin-based surfactant, and provides a cosmetic composition for hair in which the entire structure forms a lamellar liquid crystal structure by self-association of the surfactant used.

Hereinafter, the present invention will be described in more detail.

Because damaged hair has an electric charge unlike normal hair, it has a property of attracting polar substances such as moisture, while non-polar substances such as silicone do not adhere well.

However, the composition for hair provided in the present invention has a lamellar liquid crystal structure, and due to its structural feature, the hydrophobic polymer film promotes adsorption to the hair surface, thereby increasing the lipophilicity of the hair, and thus increasing the adsorption of silicone. do.

The higher aliphatic alcohol that can be used to form the lamellar liquid crystal structure in the composition of the present invention is cetyl alcohol, stearyl alcohol, cetearyl alcohol, and behenyl alcohol. It may be one or more selected from the group, but is not limited thereto.

In addition, in the present invention, the higher aliphatic alcohol is preferably used in an amount of 0.1 to 10% by weight, preferably 2 to 10% by weight, based on the total weight of the composition. This is because if the content is less than 0.1% by weight, the emulsification is structurally unstable, and if it exceeds 10% by weight, the viscosity is too high and the spreadability is poor, which is inconvenient to use.

The surfactant that can be used to form a lamellar liquid crystal structure in the composition of the present invention is a lecithin series. More specifically, as a lecithin-based surfactant, hydrogenated lecithin * C12-16 alcohol * palmitic acid (INCI name: hydrogenated lecithin (and) C12-16 alcohol (and) palmitic acid (Hydrogenated Lecithin (and) ) C12-16 Alcohols (and) Palmitic Acid), Hydrogenated Lecithin (Cosmetic Raw Material Standard (Jang Won-Ki); Hydrogenated Lecithin (Quasi-Drug Standards and Test Methods (KQC))), Lecithin (International Cosmetic Ingredients) ICID)), soybean phospholipid (Korea Science and Technology Citation Index (KSCI), KQC), etc. may be used.

In addition, in the present invention, the surfactant is preferably used in an amount of 0.1 to 15% by weight, preferably 2 to 10% by weight, based on the total weight of the composition. This is because if the content is less than 0.1% by weight, the stability of the liquid crystal structure is lowered or crystals are formed by aliphatic alcohol, and if it is more than 15% by weight, crystals of the surfactant start to form and start to mix with the lamellar structure.

In addition, the composition of the present invention may additionally be used commercially as a liquid crystal forming complex, for example, NIKKOL Nikkomulese LC (manufacturer: NIKKO CHEMICALS CO., LTD) products such as may be used.

In addition, the lamellar liquid crystal structure used in the present invention may be formed by a homomixer or an azimixer commonly used in the industry.

The hair cosmetic composition of the present invention has good applicability to the hair, can impart softness and smoothness to the hair, and in particular, the adsorption force to the hair surface is increased so that the imparted properties can be maintained for a long time. In particular, the lamellar liquid crystal structure facilitates adsorption to the hair surface, thereby enhancing the durability of the fragrance, which is an oil in the formulation.

There is no particular limitation in formulating the hair cosmetic composition of the present invention, but having a formulation such as hair tonic, hair nourishing lotion, hair essence, hair serum scalp treatment, hair treatment, hair conditioner, hair shampoo or hair lotion It may be a cosmetic composition.

In addition, in each formulation, other components other than the above-mentioned essential components can be suitably selected and formulated by those skilled in the art without difficulty depending on the type or purpose of use of other external preparations.

Hereinafter, the present invention will be described in more detail through the following examples and test examples, but the present invention is not limited to these examples.

<Production method>

1. Mix raw materials 1 to 5 uniformly and heat to 75℃.

2. Mix the raw materials 6~8 evenly and heat to 75℃.

3. While adding the mixture of 1 to the mixture of 2, mix with a mixing mixer.

4. After cooling the mixture of 3 above to 40°C, mix the raw material 9 and cool to 30°C.

[Test Example 1] Observation of liquid crystal formation

For Examples 1 to 6 and Comparative Examples 1 to 5 prepared in Reference Example 1, using a polarizing microscope NIKON ECLIPSE 80i (Nikon, Japan) was used to observe whether the liquid crystal having a lamellar structure was formed. In particular, the observation results for Examples 3 and 6 and Comparative Examples 2, 4 and 5 are shown in FIGS. 1 to 5 .

In the case of the Example prepared in Reference Example 1, it can be confirmed that a maltese cross shape is generally observed when observed with a polarization microscope.

On the other hand, when the lecithin-based surfactant was not used, the Maltese cross shape was not observed at all, and it can be seen that there is no significant difference in the presence or absence of liquid crystal formation depending on the type and ratio of the higher aliphatic alcohol.

[Test Example 2] Sensory evaluation

For the hair treatments of Examples 1 to 6 and Comparative Examples 1 to 5, sensory evaluation was performed in the following manner.

After having 10 professional evaluators use the hair treatments of Examples 1 to 6 and Comparative Examples 1 to 5, a comparative test was performed on the evaluation items shown in Table 3 below, and the lowest score was 1 and the highest score was 7, and the test was conducted. Durability was evaluated 24 hours after use.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 soft/smooth 4.1 4.3 4.3 3.8 3.8 3.9 vitality 4.5 5.2 5.4 4.3 4.5 4.6 spreadability 5.3 5.4 5.4 4.1 4.3 4.6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 soft/smooth 3.7 3.7 3.8 3.7 3.9 vitality 3.8 3.8 3.6 3.4 3.6 spreadability 3.7 3.6 4 3.9 4.1

Referring to Table 3, it can be seen that, in the case of the hair cosmetic composition according to the present invention, the Example has a similar softness as compared to the Comparative Example having a general formulation structure, but the durability and spreadability are remarkably increased.

From this, the composition according to the present invention has a lamellar liquid crystal structure, so that it is easily adsorbed to the hair surface and improves the spreadability, thereby increasing the lasting power to provide the effect that the softness of the hair can be maintained for a long time. Able to know.

[Test Example 3] Persistence test of scent

The following method was evaluated for odor lasting power when using the composition having a lamellar liquid crystal structure according to the present invention.

Five hair tresses (about 35 g) were bundled and prepared, and shampoo was applied once. After that, 5 g of the treatment of Example 3 and Comparative Example 5 was applied and maintained for 3 minutes. After rinsing the hair tress 5 times in running water, it was dried with a dryer.

Then, 400 ml of ethyl ether (HPLC grade) was added to a 500 ml glass bottle, and the dried hair tress was immersed for 90 minutes. Thereafter, impurities were removed using filter paper (Whatman No. 2), and the mixture was placed in a constant temperature water bath (30° C.) and concentrated 100 times. This was analyzed by gas chromatography (GC) (injection volume: 1 μl), and the measurement results are shown in FIG. 6 .

analysis conditions

. Analyzer: HP 5890 II GC . Detector: HP 5972 MSD

. Column: DB-1 (60m X 0.25mm X 0.25um) . Mobile phase gas: He

. Inlet temperature: 250 °C . Detecting part temperature: 280 ℃

. Oven temperature: 70℃~220℃(3℃/min) . Ionization voltage: 70eV

6, in the case of Example 3 having a lamellar structure according to the present invention, it can be seen that the fragrance persistence is high.

In addition, the odor test was performed together with the GC analysis. When the adsorption to the hair is increased by the lamellar liquid crystal structure, more conditioning components remain, and more fragrance (oil) should remain inside the lamellar liquid crystal structure than in the existing formulation. It was tested for odor power.

For the evaluation, 10 professional evaluation personnel were asked to perform a comparative test on the odor power of the hairdresser applied with the treatment after shampooing once as described above. The lowest score was 1 and the highest score was 10, and the test was conducted in such a way that a professional evaluator gave the score based on the absolute evaluation standard.

The results are shown in Table 4 and Figure 7 below.

Example 3 Comparative Example 5 0 hours 2.4 3.0 4 hours 2.7 2.7 24 hours 2.1 1.4

Referring to Table 4 and FIG. 7, it can be seen that the fragrance persistence is higher in Example 3 having a lamellar structure compared to Comparative Example 5 having a general formulation structure. This seems to be because the adsorption to hair is advantageous due to the lamellar structure and the residual amount of fragrance is increased by the block-type lamellar structure in which the oil layer and the aqueous layer are sequentially stacked.

Therefore, the use of the lamellar structure as in the present invention can be an effective method for increasing reverberation in hair.

[Test Example 4] Evaluation of adsorption amount and durability of the composition (wool swatch test)

For the hair treatments of Example 3 and Comparative Example 5, the adsorption amount and holding power were evaluated in the following manner.

1 g each of the treatment composition of Example 3 or Comparative Example 5 was treated on a wool cloth having a size of 5 cm * 5 cm, left for 3 minutes, and then washed with running water for 30 seconds. At this time, for comparison, a wool cloth not treated with the treatment composition was used as a control. Then, it was further washed 0 to 3 times with shampoo (Amos Beauty Shampoo, Amorepacific Co., Ltd.), and the wool cloth was immersed in 0.5% Rubine dye solution to develop color (Rubine dye test) . Then, the degree of colored color was measured with a colorimeter (CHROMA METER CR-100, MINOLTA CAMERA CO., LTD. Japan), and the residual amount of the composition remaining on the wool cloth was evaluated according to the number of washings. The measurement results are shown in FIG. 8 .

8, when the composition having a lamellar liquid crystal structure (Example 3) according to the present invention is applied and when the composition without a lamellar liquid crystal structure (general formulation, Comparative Example 5) is applied, one additional washing with shampoo It can be seen that the adsorption amount to the fabric is similar. However, when a composition having no lamellar liquid crystal structure is applied during additional washing with shampoo, most of the components are removed and there is little adsorption amount of the composition, whereas when a composition having a liquid crystal structure is applied, additional washing with shampoo 3 times It can be seen that a considerable amount of the composition is also adsorbed.

From this, it can be seen that the composition according to the present invention forms a lamellar liquid crystal structure to easily adsorb to the hair, and the adsorbed component is maintained for a longer period of time to increase the durability of hair softness.
