This patent application claims priority to Korean Patent Application No. 10-2021-0073244, filed with the Korean Intellectual Property Office on June 07, 2021, the disclosure of which is incorporated herein by reference.

The present invention relates to a shampoo composition having a lamellar structure comprising an anionic surfactant, a nonionic surfactant, a higher alcohol and a conditioning agent.

The hair of modern people is polluted due to exposure to ultraviolet rays, contact with the surrounding environment such as dust, and sebum secreted from the hair follicles, and frequent perming, hair drying, dyeing, combing, etc. cause considerable damage. Damaged hair, when wet or dry, is difficult to handle, such as hard to comb due to severe tangles and stiffness, and shows an unsightly appearance due to lack of luster. Accordingly, consumers' demand and preference for conditioning products that improve the appearance and feel of hair and make it easier to handle are increasing day by day.

Conditioning shampoo refers to a product that has a cleansing effect that removes contamination from the hair and scalp and a conditioning effect that makes damaged hair easy to handle and shiny and soft. Accordingly, the conditioning shampoo composition is used for the purpose of improving the texture and visual benefits of hair, for example, softness, flexibility, gloss, anti-static, ease of combing, and the like, in addition to an appropriate cleaning effect.

Recently, in domestic and overseas markets, the demand for shampoos having excellent conditioning using high-grade alcohols and oils, etc. is increasing. However, when a conditioning agent such as high alcohol is applied to a general shampoo, it does not penetrate into the hair effectively and remains on the hair surface and accumulates, resulting in a sticky and stiff feeling of use.

Recent shampoos contain cationic surfactants, hydrocarbon oils, fatty alcohols or silicones as conditioning agents to impart a conditioning effect. However, while cationic surfactants reduce friction during rinsing to make hair smooth, and increase hair adsorption of other water-insoluble conditioning substances, they also stimulate the scalp and are complexes with anionic polymers used as stabilizers. tends to form and precipitate.

In addition, hydrocarbon oils and fatty alcohols are known to provide softness to the hair and prevent static electricity, but have a disadvantage of inhibiting air bubbles by forming a complex with an anionic surfactant used for washing.

In addition, non-volatile silicone oil and polymer silicone gum (Gum) commonly used in hair conditioning agents give shine and flexibility to the hair and provide softness to the hair after drying, while lacking moisturizing properties and poor compatibility with other ingredients. Due to its compatibility, there is a limitation in its utility, and when used repeatedly for a long period of time, it accumulates on the hair, reducing softness and accelerating recontamination by dust and sebum.

In addition, the silicone oil acts as an antifoaming agent such as oil in the shampoo composition, remarkably lowering the cleaning ability of the anionic surfactant.

In order to improve this, the development of a shampoo composition capable of providing excellent conditioning benefits to hair while maintaining excellent washing performance while using anionic surfactants is required.

Accordingly, the present inventors made an effort to form a lamellar structure by mixing an anionic surfactant, a nonionic surfactant, a higher alcohol, and a conditioning agent in an appropriate amount, thereby making a shampoo composition having an excellent hair conditioning effect.

In particular, it was confirmed that, when an anionic surfactant, an amide-based nonionic surfactant, a higher alcohol, and a conditioning agent were mixed in an appropriate ratio, a lamellar structure was effectively formed and the hair conditioning feeling was improved.

Accordingly, it is an object of the present invention to provide a conditioning shampoo composition having a lamellar structure comprising an anionic surfactant, a nonionic surfactant, a higher alcohol, and a conditioning agent.

The present invention relates to a conditioning shampoo composition having a lamellar structure comprising an anionic surfactant, a nonionic surfactant, a higher alcohol and a conditioning agent, and the present inventors provide an anionic surfactant, a nonionic surfactant, a higher alcohol, and a conditioning agent was formulated in an appropriate amount to form a lamellar structure, and through this, it was confirmed that an excellent hair conditioning effect was exhibited and the hair feeling was improved.

Purified water, anionic surfactant, and pH adjuster among the components listed in Table 2 were weighed in a beaker and then uniformly mixed at a temperature of 80 to 85° C. at 500 rpm for 5 minutes using an Agimixer to prepare an aqueous phase. After weighing the higher alcohol, nonionic surfactant, and oil as the oil phase in a beaker, the mixture was mixed with the aqueous phase at a temperature of 80 to 85° C. and uniformly mixed for 5 minutes using a homomixer. Then, after cooling to 30 °C, the bubbles were removed to prepare Comparative Examples 1 to 5.

In Comparative Example 6, all the raw materials were weighed in a beaker and then uniformly mixed for 10 minutes at 500 rpm at room temperature using an Agi-mixer, and then bubbles were removed to prepare the contents.

Comparative Example 7 is after measuring 5% of the total weight % of the components 1 to 5 described in Table 1 of Example 1 (32 wt%: x = 100: 5, x = 1.6 wt%), the remainder The raw materials were measured and prepared by uniformly mixing.

Experimental Example 1. Confirmation of lamellar structure formation

The ratio of (anionic surfactant)/(oil phase) of the prepared Examples 1 to 3 and Comparative Examples 1 to 5 and 7 is shown in Table 3 below.

	Example 1	Example 2	Example 3	Comparative Example 1	Comparative Example 2	Comparative Example 3	Comparative Example 4	Comparative Example 5	Comparative Example 7
Ratio of (anionic surfactant)/(oil phase)	5.56	5.56	5.56	7.5	6.25	12.5	12.5	12.5	5.56

In order to confirm the formation of the lamellar structure according to the (anionic surfactant)/(oil phase) ratio of Examples and Comparative Examples, the interfacial area was calculated using a Small Angle X-ray Scattering (SAXS) device. . The small-angle X-ray scattering device uses a scattering phenomenon that occurs at a very small angle in proportion to the interfacial area between the structure and the particles, and can calculate the interfacial area by analyzing the scattering curve. When the q-value of the first peak in the q-value corresponding to the x-axis is 1, when the ratio of the small-angle X-ray scattering peak is 1: 2: 3, the lamellar structure, 1:

:

When it appears as a cubic structure, 1:

: When it appears as 2, it is interpreted as a hexagonal structure. A small-angle X-ray scattering device was measured under a condition of measuring distance = 2 m, and the results are shown in FIGS. 1 to 5 .

As shown in FIG. 1 , in Example 1, the q-value (x-axis) ratio was observed to be 1:2:3:4, confirming that a lamellar structure was formed. In addition, as shown in FIG. 2, in Example 2, the q-value (x-axis) ratio was observed to be 1: 2, and a lamellar structure was formed, and as shown in FIG. 3, Example 3 had a q-value (x-axis) A ratio of 1: 2 was observed to confirm that a lamellar structure was formed.

As shown in FIG. 4 , in Comparative Examples 1 and 2, the q-value (x-axis) ratio was observed to be 1:2, thereby confirming that a lamellar structure was formed. On the other hand, in Comparative Examples 3 to 5, the measurement peak did not appear, so a lamellar structure was not formed. In particular, in Comparative Example 4, different types of anionic surfactants were prepared, but different types of anionic surfactants did not help to form a lamellar structure. And Comparative Example 5 additionally contains a nonionic surfactant, but the addition of the nonionic surfactant did not help much when forming the lamellar structure, so the main factor in forming the lamellar structure is (anionic surfactant phase) / It is the ratio of (oil phase), and the higher this ratio, the more it means that the formation of the lamellar structure is hindered.

In addition, as shown in FIG. 5 , in Comparative Example 7, the ratio of anionic surfactant: oil phase was 5.56:1, which was the same as in Examples 1 to 3, but a lamellar structure was obtained by including 1.6% by weight of the lamellar structure composition compared to the total cosmetic composition. It was confirmed that it did not form.

Through this, it was confirmed that the weight ratio of the anionic surfactant to the oil phase and the content of the lamellar structure composition were important to form the lamellar structure. However, the weight ratio of the anionic surfactant to the oil phase is not limited to 5.56:1, and since the amount of the anionic surfactant activated due to the combination of the anionic surfactant and the cationic polymer decreases, even at a weight ratio other than 5.56:1, the lamellar structure could be observed.

Experimental Example 2. Confirmation of hair conditioning effect

In order to evaluate the conditioning efficacy of Examples 1 to 3 and Comparative Examples 6 and 7 prepared by Preparation Example of the present invention, Dia-stron's Fibra-one was used for wet hair and dry hair A comb texture evaluation experiment was conducted.

2-1. Comb texture evaluation of wet hair

To evaluate the comb texture of wet hair, purchase a hair tress of natural black hair (3 g, 180 to 200 mm), rinse with plenty of water, apply 0.35 g of the composition, massage for 30 seconds, and then run under running water without massaging for 30 seconds. rinsed off The wet hair bundle was hung on the load cell ring of the Fibra-one, the comb was fixed using a jig, and the load value taken when combing using the Fibra-one was measured and shown in Table 4 and FIG. 6 .

In this experiment, the Work (J) value is a value indicating the degree of force applied to combing, that is, the goodness of brushing. The smaller the Work (J) value, the better the combing texture is.

Unit: Work (J)	Comparative Example 6	Comparative Example 7	Example 1	Example 2	Example 3
comb texture	0.02985	0.02301	0.04869	0.03089	0.03149

As can be seen in Tables 4 and 6, Examples 2 and 3 and Comparative Examples 6 and 7 containing the same amount of the cationic polymer and the worst rain feeling in Example 1 without the cationic polymer were It showed a value lower than Example 1.

When the hair is wet, the cationic polymer and the surfactant work together to form a (+) charged complex called coacervate on the hair surface. This is because it coats and softens it.

2-2. Evaluation of comb texture for dry hair

To evaluate the comb texture of dry hair, purchase a hair tress of natural black hair (3 g, 180 to 200 mm), rinse with sufficient water, apply 0.35 g of the composition, massage for 30 seconds, and then massage in running water for 30 seconds rinsed without After drying the wet hair bundle for 3 minutes using a hair dryer, hang the dry hair bundle on the load cell hook of the Fibra-one, fix the comb using a jig, and then use the Fibra-one to comb the load. The values were measured and shown in Table 5 and FIG. 7 .

In this experiment, the Work (J) value is a value indicating the degree of force applied to combing, that is, the goodness of brushing. The smaller the Work (J) value, the better the combing texture is.

Unit: Work (J)	Comparative Example 6	Comparative Example 7	Example 1	Example 2	Example 3
comb texture	0.03978	0.04558	0.01730	0.02355	0.01531

As can be seen in Table 5 and Figure 7, in Comparative Examples 6 and 7, which do not form a lamellar structure, the most force was applied to the comb, so the texture was not good, but anionic surfactants, nonionic surfactants, higher alcohols and conditioning In the case of Examples 1 to 3 containing the agent in a certain ratio, it was shown that the lamellar structure was formed so that the penetration of the lipid component into the skin and hair was easier, and thus excellent in comb texture. Through this, it was confirmed that, when a shampoo composition having a lamellar structure was used, an excellent hair conditioning effect was exhibited.

The present invention relates to a shampoo composition having a lamellar structure comprising an anionic surfactant, a nonionic surfactant, a higher alcohol and a conditioning agent.
