Description

  The present invention relates to a shampoo composition, and more particularly, contains a specific dextrin branched fatty acid ester and a specific cationic cellulose derivative having a cationic hydrophobic group, and is easy to use with reduced squeaking during washing. The present invention relates to a shampoo composition that gives a moist film feeling to the later hair and can maintain a sense of volume as well as a soft feeling.

Conventionally, shampoos for hair are required to be effective as a cleaning agent. However, to reduce the squeaking of the hair that occurs during washing and to improve the feel of the finger, and to improve the feel after washing, the desired usability Various components are contained depending on the purpose and effect. (For example, see Non-Patent Document 1)
In particular, when a conditioning effect such as imparting smoothness, moistness, moisturization or cohesion to the hair after shampooing is required, quaternized nitrogen such as trimethylammonium chloride or dimethyldiallylammonium chloride is added to the composition. There are many methods in which a cationic polymer, an oil such as an ester oil or a silicone derivative, a cationic surfactant such as a quaternary ammonium salt or a tertiary amidoamine is added. (For example, see Patent Documents 1 to 3)

In recent years, shampoos tend to require a natural soft feeling and softness in the hair that has been dried after washing, and a finished effect with a voluminous feel. However, even in a shampoo having such an effect, for example, on a drizzle or rainy season, the hair may swell and spread due to the nature of the hair, resulting in poor combing, soft softness and volume. The feeling may be lost.
Therefore, it is conceivable to prevent the original properties of hair from appearing as much as possible by a method such as blending a large amount of the above-described conditioning components.

  However, in the technique using the cationic polymer of Patent Document 1, if it is contained in a large amount in the hair cosmetic for the purpose of imparting a higher conditioning effect, it will be rather stiff due to excessive adsorption of the cationic polymer to the hair. In some cases, natural soft feeling and softness may be impaired. Further, when an oil agent or a cationic surfactant as described in Patent Document 2 or Patent Document 3 is used, emollient feeling and treatment feeling can be imparted to hair, but for example, high humidity such as a relative humidity of 75% or more. In some cases, it was difficult to suppress hair undulation and maintain good combing and softness, especially volume.

  Accordingly, the object of the present invention is to suppress the squeak during washing, improve the finger passage, give the hair a moist film feeling after washing, and have a soft feel and volume even under high humidity conditions. It is to provide a shampoo composition capable of sustaining a feeling and making hair having a good feel.

Next, the average substitution degree of the cationic hydrophobic group with respect to the water-soluble cellulose derivative is not particularly limited, but is preferably 0.0001 to 0.1 mol per mol of anhydroglucose unit constituting the cellulose. Further, the average degree of substitution of the trimethylammonium-containing group in the water-soluble cellulose derivative is not particularly limited, but is preferably 0.01 to 1 mol per mol of anhydroglucose unit.

  In the present invention, the component (C) is particularly preferably a cationic cellulose derivative having two kinds of a lauryldimethylammonium-containing group and a trimethylammonium-containing group. Such compounds are listed as “POLYQUATERNIUM-67” (Polyquaternium-67) in “International Nomenclature of Cosmetic Ingredients” (INCI), which can be used as a preferred example of the component (C) of the present invention. Polyquaternium-67 is commercially available as “SoftCAT SX-1300H”, “SoftCAT SX-400H”, etc., SoftCAT SX series, SoftCAT SL series, SoftCAT SK series (above, manufactured by Dow Chemical Co., Ltd.). It can be suitably used as the component (C) of the invention.

  In the shampoo composition of the present invention, the cationic cellulose derivative of component (C) can be used alone or in combination of two or more in the above-mentioned range. The content is not particularly limited, but is preferably 0.01 to 3%, particularly preferably 0.05 to 2%, in order to sufficiently obtain the effects of this patent. When the component (C) is contained in a preferred range, particularly in providing a moist film feeling and a soft feeling to the hair after washing by the cooperative function with the above-described component (B) dextrin fatty acid ester, An excellent effect can be obtained.

The reason for the above cooperative operation of the component (B) and the component (C) in the present invention can be considered as follows, but this is one hypothesis and the present invention is limited. is not.
In the present invention, the component (C) has an adsorption action on hair, which is a common property of cationic celluloses. In addition, this greatly increases the adsorption of the dextrin fatty acid ester of the component (B) on the hair. It is thought to promote. Due to the cooperative adsorption of these two components to the hair, the dextrin fatty acid ester of the component (B) that is dried on the surface of the hair after application, etc., does not impair the texture of the hair, even in a high humidity environment. It is thought that it gives the hair a moist film feeling that suppresses swell and spread. This cooperative function is peculiar to the combination of the component (B) and the component (C). For example, as described later, polyquaternium-10 which is a general cationic cellulose derivative instead of the component (C) is used. When (O- [2-hydroxy-3- (trimethylammonio) propyl] hydroxyethylcellulose chloride) is used, the cooperative function with the component (B) is not observed, and the effect of the present invention is I can't get it. In addition, when a dextrin fatty acid ester of a general oil gelling agent is used instead of the component (B), sufficient cooperation with the component (C) cannot be obtained, and the effects as in the present invention are obtained. It ’s difficult. In addition, dextrin fatty acid esters, which are general oil gelling agents, are different from ordinary oils, so they have a significant effect on the feel of hair cosmetics such as shampoos, and the freedom of formulation is limited in order to obtain a good feeling of use. It is often done.

This is preferable because it is possible. In particular, when the detersive surfactant of component (A) is mainly an anionic surfactant or amphoteric surfactant, component (B) becomes difficult to dissolve in the composition, so component (D) is added. Thus, the range in which the component (B) can be contained can be expanded, the range of the prescription can be expanded, and a shampoo composition with higher effect of this patent can be obtained.
