Description

Shampoo composition

Technical Field

The present invention relates to shampoo compositions containing a particular cationised polymer and a particular surfactant.

Background

In general, in a shampoo composition, a sulfuric acid-based anionic surfactant is contained in order to wash off dirt of hair. However, although sufficient cleansing power can be ensured, there is a problem that hair is coarse and easily tangled, and finger-pass ability is deteriorated. Therefore, an amino acid type surfactant is blended to improve the cleaning property and the rough feeling during cleaning. However, the foaming property of the shampoo composition using the amino acid type surfactant may be deteriorated as compared with the shampoo composition using other anionic surfactants.

Conventionally, a shampoo composition disclosed in patent document 1 is well known. Patent document 1 discloses a shampoo composition containing sodium cocoyl methyl taurate as an amino acid type surfactant, an N-acyl amino acid salt, and polyquaternium-10 (polyquaternium-10) as a cationized polymer. The shampoo composition improves lathering by cationizing the polymer.

In addition, shampoo compositions containing a cationized polymer and an oily component for improving the feel during shampooing are well known. For example, patent document 2 discloses a shampoo composition containing an ionic surfactant, cationized cellulose as a cationized polymer, a high-molecular silicone resin, and the like.

Disclosure of Invention

Problems to be solved by the invention

However, in the shampoo composition of patent document 1, the cationic polymer contained in the shampoo excessively adsorbs to the hair, so that excessive conditioning (over conditioning) occurs in which the conditioning (conditioning) component in the conditioning agent applied thereafter does not adhere to the hair, and the hair may become hard and poor in touch after the conditioning. Therefore, the shampoo compositions up to now have not been able to achieve both the effect of improving lather and the effect of improving excessive conditioning. In addition, the touch after the care and the touch during the hair washing are independent of each other.

Further, when the content of the cationized polymer is increased, clouding is liable to occur, and when the appearance of the formulation is made transparent for improving the appearance, it is difficult to improve the stability of the transparent formulation at low temperature and room temperature while blending a predetermined amount of the cationized polymer. Here, the stability of the transparent preparation means that the preparation maintains a transparent state. Even if the stability of the transparent preparation is improved by selecting the kind of the surfactant, it is difficult to improve the stability of the transparent preparation while maintaining the effects of touch and foam quality due to the cationized polymer, and it is very difficult to achieve both the stability of the transparent preparation and touch and foam quality. In addition, the effect of improving the feel of an oily component is weaker than that of a cationized polymer, and turbidity is likely to occur due to the combination with a surfactant, and therefore it is difficult to improve the feel and to make the appearance of a preparation transparent.

The problem to be solved by the present invention is to provide: (i) a shampoo composition which can improve foaming property and improve excessive conditioning; or (ii) a shampoo composition which can achieve both the stability of a transparent preparation and the touch and foam quality at the time of shampooing.

In order to solve the above-mentioned problem (ii), a shampoo composition according to embodiment 2 is characterized by containing 0.2 mass% or more of (a2) O- [ 2-hydroxy-3- (trimethylammonio) propyl ] hydroxyethyl cellulose chloride, (B2) triethanolamine salt of amino acid type surfactant, and (C2) coconut oil fatty acid PEG-7 glyceride, and by containing 0.3 mass% or less of oily component and substantially not containing an anionic surfactant to which a sulfate salt is added.

The shampoo composition may further comprise (D2) at least one solvent selected from the group consisting of 1, 3-butylene glycol, dipropylene glycol, propylene glycol, glycerin, and monohydric alcohols having a main chain carbon number of less than 4.

In the shampoo composition, the mass ratio (C2+ D2)/(a2) of the total of the content of the component (C2) and the content of the component (D2) to the content of the component (a2) may be 20 or less.

In addition, the cleansing property and the feeling of touch of the hair can be improved. Therefore, the shampoo composition may contain a surfactant other than the above-described surfactants within a range not to impair the effects of the present invention. Examples of the surfactant include anionic surfactants, cationic surfactants, amphoteric surfactants, and nonionic surfactants other than those mentioned above.

Therefore, the stability of the transparent preparation, the touch and the foam quality can be achieved at the same time.

(2) In the case where the shampoo composition further contains a solvent of the (D2) component, the stability of the transparent preparation particularly at low temperature can be improved.

The above embodiment 2 can be modified as follows. Embodiment 2 and the following modifications can be implemented in combination with each other within a range not technically contradictory.

The 5 panelists determined the touch feeling at the time of hair washing using the same criteria as the evaluation of the touch feeling at the time of hair washing in the example of embodiment 1. The results are shown in the columns of "feel" in tables 3 and 4.

(bubble quality)

The foam quality of the shampoo composition was evaluated in the form of feeling when the foam was touched with a hand and feeling of elasticity judged from the appearance. Specifically, about 3g of each shampoo composition was placed on a flat plate at 25 ℃ and the shape of the foam and the elasticity when touched with a hand were observed by 5 panelists (sensory evaluation) and evaluated according to the following criteria. The scores were made on the following 5 scales: the foam was excellent (5 minutes) in both of shape retention and elasticity; good shape retention and high elasticity (4 min); the case where the shape is maintained but the elasticity cannot be said to be high is normal (3 min); a slightly poor shape retention property and a slightly low elasticity (2 min); the shape was not retained and the elasticity was very low, which was poor (score 1). The average value was calculated for the scoring results of each panelist, and an average value of 4.6 points or more was regarded as "excellent: 5 ", 3.6 points or more and less than 4.6 points are scored as" good: 4 ", scores of 2.6 or more and less than 3.6 are recorded as" general: 3 "; scores of 1.6 or more and less than 2.6 were recorded as "slightly poor: 2 "; and less than 1.6 is scored as "poor: 1 "as a result of the foam quality evaluation 1. The results are shown in the columns of "bubble quality" in tables 3 and 4.

[ Table 3]

[ Table 4]

As shown in table 3, it was confirmed that the evaluation items of the examples were generally the same or higher results.

As shown in Table 4, it was confirmed that the evaluation of the touch feeling was inferior to that of each example in comparative example 2-1 containing no component (C2). It was confirmed that, in comparative example 2-2 containing (C2) steareth-2 in place of the (C2) component, the evaluation of the stability of the transparent preparation was inferior to that of each example. It was confirmed that in comparative examples 2 to 3 containing (B2) lauroyl sarcosine Na and cocoyl glutamic acid Na in place of the component (B2), the stability of the transparent preparation, the touch and the foam quality were not compatible with each other, as compared with the respective examples. It was confirmed that in comparative examples 2 to 4 containing (B2) lauroylsarcosine Na in place of the component (B2), the stability, touch and foam quality of the transparent preparation were not compatible with those of the examples. It was confirmed that in comparative examples 2 to 5 containing (B2) cocoyl glutamic acid Na in place of the component (B2), the stability of the transparent preparation, the touch and the foam quality were not compatible with each other, as compared with the respective examples. It was confirmed that comparative examples 2 to 6 containing an anionic surfactant to which a sulfate was added had inferior touch evaluation to the examples. It was confirmed that comparative examples 2 to 7 containing a predetermined amount of an oily component had inferior stability and feeling of touch to the transparent preparations in each example. It was confirmed that, in comparative examples 2 to 8 containing no component (A2), the evaluation of touch and foam quality was inferior to that of each example. It was confirmed that, in comparative examples 2 to 9 in which the content of the component (A2) was less than 0.2% by mass, the evaluation of the touch and the foam quality was inferior to those of the examples. It was confirmed that in comparative examples 2 to 10 in which the content of component (A2) was less than 0.2% by mass and component (b2) contained lauroyl sarcosine Na and cocoyl glutamic acid Na, the stability of the transparent preparation, the touch and the foam quality could not be simultaneously achieved as compared with the respective examples.
