Description

Waterless shampoo {Waterless shampoo}

The present invention relates to a waterless shampoo.

In general, hair is contaminated by sweat and various sebum secreted through human metabolism. And more polluted by the pollutants generated by the pollution of the atmospheric environment.

Conventional shampoos are in the form of a gel or paste with high viscosity. In the usage method, 1) wet the hair with water, 2) put the shampoo on the hair, 3) rinse, bubble out, 4) rinse with water 5) Dry the hair with a dry towel or towel.

In addition, the main ingredient of the existing shampoo is the basic prescription consisting of anionic surfactant with surfactant and cleaning power and bubble power, amphoteric surfactant, amphoteric surfactant to solubilize auxiliary and fragrance, pH adjusting agent, thickener, preservative and water In recent years, a treatment effect has been added, and it contains a moisturizing agent, a conditioning agent and a hair protecting agent. Surfactants account for 40-50% of the total shampoo composition. These surfactant ingredients are non-volatile materials, and the hair remaining on the head is build-up as well as skin irritation, resulting in hair loss and slow drying speed.

This is why existing shampoos must be thoroughly rinsed with water. Conventional shampoos require rinsing with water, so it is difficult to use for long-term hospitalized patients, inconvenient behavior, soldiers, fishing, mountain climbers, and long-distance travelers.

Waterless shampoo has been introduced, however, since it does not rinse the foam after use, components remaining on the scalp or hair cause skin irritation, and waterless shampoo usually contains ethanol for volatilization, There is a problem that can induce.

Korean Patent Laid-Open Publication No. 2013-114986 discloses a dry shampoo which can be used without water.

The present invention includes 2 to 6% by weight of sodium cocoyl glutamate, 0.5 to 5% by weight of cocamidopropyl betaine and 0.1 to 1% by weight of tocolol, thereby eliminating components causing scalp irritation, The present invention also relates to a waterless shampoo having detergency.

Hereinafter, the present invention will be described in detail.

The waterless shampoo of the present invention comprises 2 to 6% by weight of sodium cocoyl glutamate, 0.5 to 5% by weight of cocamidopropyl betaine and 0.1 to 1% by weight of totalol.

Sodium cocoyl glutamate is an anionic surfactant, and anionic surfactant is usually used because sulfate surfactant is excellent in detergency, but it has a problem that stimulation occurs when it is present in scalp or hair.

However, the present invention includes sodium cocoyl glutamate having a small irritation and excellent washing power as an anionic surfactant. Therefore, do not wash the foam with water and wipe it with a towel so that the foam does not cause irritation even if it remains on the scalp or hair.

Sodium cocoyl glutamate is included in 2 to 6 wt%. When the content is less than 2% by weight, foam generation is insignificant. When the content is more than 6% by weight, the foam uniformity is lowered, and moisture of hair or scalp can be excessively removed by strong washing force. Preferably from 3 to 5% by weight, from the standpoint of simultaneously exhibiting excellent washing power, foam uniformity and water retention effect.

Cocamidopropyl betaine is a cationic surfactant which, together with sodium cocoyl glutamate, shows excellent detergency without irritation, has low detergency as compared to sodium cocoyl glutamate, and uses only sodium cocoyl glutamate alone It is possible to prevent excess moisture from being removed from the scalp or hair.

The content of cocamidopropyl betaine is in the range of 0.5 to 5% by weight, and the content thereof can be adjusted according to the content of sodium cocoyl glutamate within the above content range. For example, as the content of sodium cocoyl glutamate decreases, the detergency becomes insufficient, so that the content of cocamidopropyl betaine can be increased to supplement the detergency. If the content is less than 0.5% by weight, the detergency and moisture preservation effect may be insignificant. If the content is more than 5% by weight, the content of sodium cocoyl glutamate may be decreased and the detergency may be insufficient. Preferably 1.5 to 2.5% by weight.

The mixing ratio of the sodium cocoyl glutamate and the cocamidopropyl betaine is not particularly limited and may be, for example, in a weight ratio of 1: 0.4 to 0.8. If the weight ratio is less than 1: 0.4 and the content of cocamidopropyl betaine is small, sodium cocoyl glutamate may be added in order to achieve detergency, so that the foam uniformity may be lowered and the moisture of the scalp or hair may become insufficient. If the weight ratio is more than 1: 0.8 and the content of cocamidopropyl betaine is large, the washing power may be somewhat insufficient. Preferably in a weight ratio of 1: 0.4 to 0.6.

According to another embodiment of the present invention, the waterless shampoo of the present invention comprises sodium cocoyl glutamate and cocamidopropyl betaine in a total weight of 4.5 to 9% by weight and a weight ratio of 1: 0.4 to 0.8, Is in the range of 1: 0.5 to 0.7. It can exhibit excellent cleaning power and foam uniformity within the total content and content ratio, and at the same time, can preserve moisture.

In the case of waterless shampoo, it is not rinsed with water, and often contains ethanol for volatilization after use, whereby the scalp may be irritated. However, the waterless shampoo of the present invention can minimize irritation to hair and scalp without volatilization due to the addition of ethanol using the above-mentioned low-magnetic surface active agents.

Totorol is a natural preservative, and shampoos usually contain chemical preservatives such as methyl paraben, which can cause irritation when remaining on the scalp or scalp.

However, the waterless shampoo of the present invention, together with the above-mentioned low-magnetic-field surfactant, contains totally natural preservative, which is not a chemical preservative, so that the stimulation can be minimized even if the bubble remains in the hair or the hair.

Totalol is included in 0.1 to 1% by weight. When the content is less than 0.1% by weight, the preservative effect is insignificant. When the content is more than 1% by weight, the degree of improvement of the effect is insufficient.

The waterless shampoo of the present invention may further comprise 1 to 3% by weight of glycerin and 1 to 5% by weight of dipropylene glycol.

Glycerin and dipropyleneglycol are moisturizing ingredients, and they help prevent frizziness and dryness of the scalp.

Glycerin is a hypoallergenic ingredient that is also used as a raw material for foods and medicines. Dipropylene glycol has less penetration into the skin and is hypoallergenic and has excellent moisturizing effect. Dipropylene glycol additionally serves to dissolve menthol, which will be described later.

Glycerin is contained in an amount of 1 to 3% by weight, and dipropylene glycol is contained in an amount of 1 to 5% by weight. If the content is less than the above range, the moisturizing effect may be insufficient. If the content exceeds the above range, the content of the other components may be lowered.

Although the content ratio of glycerin and dipropylene glycol is not particularly limited, glycerin may be contained in a weight ratio of 1: 1.2 to 2.5, preferably in a range of 1: 1.2 to 2.5 in view of reducing sticky heavy feeling and increasing softness of hair because of slight stickiness. If the weight ratio of dipropylene glycol is less than 1: 1.2, it may give a feeling of stickiness. If the weight ratio is more than 1: 2.5, the moisture resistance will be lowered. . More preferably in a weight ratio of 1: 1.5 to 2 in view of the above aspect.

In another embodiment of the present invention, the total content of glycerin and dipropylene glycol according to the present invention is 2 wt% to 8 wt%, the weight ratio is 1: 1.2 to 2.5, preferably 1: 1.5 to 2 Lt; / RTI > In such a case, deterioration of the detergency can be minimized, and moisture retention and light feeling can be exhibited.

The waterless shampoo of the present invention may further comprise 0.1 to 1% by weight of menthol.

In normal shampoo, when the foam is rinsed with water, the water evaporates and the temperature of the scalp is lowered so that the user can feel coolness, so-called refreshing feeling.

However, since the waterless shampoo is not rinsed with water, the waterless shampoo of the present invention includes a menthol so that the user can feel a refreshing feeling.

In addition, menthol is a natural ingredient extracted from peppermint, and there is little skin irritation caused by its addition.

Menthol is included in the amount of 0.1 to 1% by weight. If the content is less than 0.1% by weight, the effect of imparting a refreshing sensation is insignificant. If the content is more than 1% by weight, the degree of irritation may be excessive and the preference degree may be lowered.

Menthol is preferably used together with dipropylene glycol which can dissolve it, since it melts when it melts and does not mix with water.

In addition to the above components, the waterless shampoo of the present invention may further comprise a plant extract such as a pH adjusting agent, a flavoring agent, a solubilizing agent, a whitening water, aloe vera gel, green tea extract, and chamomile flower extract.

Most healthy when human hair is slightly acidic (pH is about 5.5), the waterless shampoo of the present invention may have a pH of, for example, about 4.5 to 6.0 including a pH adjusting agent.

Examples of usable pH adjusting agents include glutaric acid, citric acid, glycolic acid, oxalic acid, and latic acid.

The pH adjusting agent may be, for example, 0.01 to 1% by weight, but is not limited thereto.

Natural fragrances such as rosemary, lavender, peppermint, eucalyptus, lemon and orange oil can be used as the fragrance, and the solubilizing agent can be added to dissolve the fragrance, and a polysorbate-based material as a vegetable raw material can be used have.

The waterless shampoo of the present invention may appropriately adopt the above-mentioned components according to specific needs, and then add water to adjust the overall composition, so that the remaining amount of the entire composition is occupied by water. Preferably, the components are adjusted to have the aforementioned content ranges.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to examples.

Experimental Example

1. Evaluation of bubble generation and air bubble uniformity

In order to confirm the degree of foaming, 50 g of the waterless shampoo of Examples and Comparative Examples was placed in a 200 ml container and shaken up and down 15 times under the same conditions. After one minute, the height of foam was measured.

The uniformity of the air bubbles was measured by pumping the waterless shampoo into the bubble container and pumping the air bubble five times from 11th to 15th times.

Second, pour the contents into the bubble container, pour the contents until the contents are released, discard the first 10 times, and observe and record the uniformity of the bubbles with respect to the pumped parts from 11 to 15 times in total. (With drawing)

○: When pumping, only small and uniform bubbles were observed and no large bubbles were observed

B: 1 or 2 large bubbles were observed when pumping

X: 3 large bubbles were observed when pumping

2. Moisture power Test

The moisturizing power of the waterless shampoo of Examples and Comparative Examples was evaluated on the panels of 10 to 3 persons, 20 to 11 persons, 30 to 9 persons, and 40 to 7 persons.

The panels were shampooed with waterless shampoos of Examples and Comparative Examples. After 1 hour, the degree of softness of the hair according to the ease of combing and the degree of moisturizing of the scalp after 2 hours were evaluated. The evaluation was carried out on a clear day at a temperature of 22 to 26 DEG C and a humidity of 60 to 65%.

The scalp moisturizing and hair softness were evaluated by a minimum of 1 point and a maximum of 5 points.

3. Scalp stimulation test

The panels were shampooed with waterless shampoos of the Examples and Comparative Examples once a day for two weeks, and the degree of scalp stimulation was measured with a scalpel diagnostic device to determine whether the skin was horny or not, and whether the scalp elasticity was maintained .

4. Cool feeling test

Referring to Table 2, it was confirmed that the waterless shampoo of the present example produced a lot of bubbles and was excellent in washing power, and foam of uniform size was generated, and thus it could be preferably used in a bubble container. In addition, it was confirmed that the scalp moisturizing effect and the softness effect of the hair were excellent, and a refreshing feeling was imparted with less skin irritation.

Specifically, the examples showed generally excellent effects, and Examples 1 and 4, which were outside the preferred weight ratio of glycerin and dipropylene glycol, showed somewhat reduced scalp moisturizing and softness of the hair, but still excellent.

Example 5 was slightly better than Example 3, except that the preferred weight ratio of sodium cocoyl glutamate to cocamidopropyl betaine was lowered, but the scalp moisturizing and hair softness were somewhat lowered, but still excellent.

In Example 6, the feeling of refreshing was increased by including ethanol, but skin irritation was somewhat generated.

However, the waterless shampoo of the comparative example was poor in detergency or difficult to obtain even-sized foam. Or the scalp moisturizing effect, the softness of the hair, and the skin irritation.

Specifically, in Comparative Examples 1 to 5 using only a small amount of surfactant, overall performance such as cleaning power and foam uniformity were all poor.

In Comparative Example 6, sodium cocoyl glutamate was used in an excess amount and the washing power was excellent, but the foam uniformity and the scalp moisturizing ability were lowered.

In Comparative Example 7, the cocamidopropyl betaine was used in excess and the detergency was lowered.

In Comparative Example 8, only the sodium cocoyl glutamate was used, the foam uniformity was low, and large bubbles were easily blown off, causing a problem of flowing down on the scalp or hair. Also, the moisturizing and softening effect of the hair decreased.

In Comparative Example 9, detergency was lowered by using only cocamidopropyl betaine.

In Comparative Example 10, a sulfate anionic surfactant was used in place of sodium cocoyl glutamate, the scalp moisturizing condition deteriorated and the scalp keratinized easily.

In Comparative Example 11, sodium myristoyl sarcosinate was used in place of sodium cocoyl glutamate. In Comparative Example 12, lauryl betaine was used instead of cocamidopropyl betaine to reduce washing, scalp moisturizing and hair softness.

In Comparative Example 13, methylparaben, a chemical preservative, was used to induce skin irritation.
