Description

  The present invention relates to a detergent composition that has good hair feel after foaming and washing / drying, has good storage stability, and suppresses excessive adsorption of blended components to the background.

  The most common cleaning component of a hair cleaning composition is polyoxyalkylene alkyl ether sulfate. This cleaning component is a low-cost cleaning component with good foaming and less skin irritation. When this surfactant and cationic polymer are used together in the composition and the foamed hair cleansing composition is rinsed, a complex of both is formed and adsorbed to the hair, giving a good feel to the fingers and between the hair Prevents tangling. Further, this composite improves the smoothness of the hair after the silicone compound blended in the cleaning composition is adsorbed to the hair together with the composite and dried with a dryer.

  However, this complex adsorbs not only on hair but also on the ground. When cationized cellulose or cationized guar gum, which is a commonly used cationic polymer, is used in combination, the composite tends to form a film, and if it is excessively adsorbed, the surface may become sticky or feel sticky. Moreover, it may become easy to feel a light itch for a person with weak skin.

In addition, since these cationic polymers are poor in the effect of stabilizing the dispersion of the silicone compound, when the cleaning composition is stored in a place where the storage conditions are poor, for example, at a high temperature such as directly under the roof of a warehouse in the summer, A particle diameter becomes large and a silicone compound may adhere excessively to the ground. Furthermore, since the composite also adsorbs the preservative coexisting in the cleaning composition to the background, some people may feel itching or the like.
From the above, the feel of the hair after foaming, washing and drying is good, the storage stability is good, excessive adsorption of the complex and preservative to the background is suppressed, the background is not sticky, A cleaning composition that suppresses itching has been desired. In addition, the following is mentioned as a prior art document relevant to this invention.

Japanese Patent Laid-Open No. 1-128914 JP 11-79956 A JP 2000-290148 A JP 2002-187819 A

  The present invention has been made in view of the above circumstances, has a good feel of the hair after foaming and washing / drying, has good storage stability, and suppresses excessive adsorption of the complex or preservative to the background, An object of the present invention is to provide a cleaning composition that does not cause the skin to become sticky and suppresses itching of the skin.

  As a result of diligent studies to achieve the above object, the present inventor has used a polyoxyalkylene alkyl ether sulfate as a cleaning component, a cationic polymer as a rinsing performance imparting agent, and a cleaning compound containing a silicone compound as a hair feel improving agent. Using the base, we have intensively studied the technology to prevent adsorption to the background. As a result, as a cationic polymer, (D) cationized cellulose or cationized guar gum and (E) dimethyldiallylammonium chloride / acrylamide copolymer are used in combination, and the total content thereof is 0.1 to 1% by mass, And the above-mentioned mass ratio (D) / (E) = 1/9 to 9/1, the aromatic carboxylic acid represented by the general formula (1) or a salt thereof is blended in an amount of 0.01 to 0.5% by mass, And it was discovered that by adjusting the pH of the cleaning composition to 3.0 to 5.5, the composite and the preservative are prevented from excessively adsorbing to the background, and the storage stability is improved. More specifically, (1) since a composite having a physical property that is difficult to form a film and is difficult to stick can be deposited, it is possible to suppress the composite and the preservative from being excessively adsorbed on the ground. (2) The stable dispersion force of the silicone compound is improved, and it can be suppressed that the silicone compound has a large particle size and is excessively adsorbed on the background. (3) By using the aromatic carboxylic acid represented by the general formula (1) or a salt thereof, which is highly effective in a small amount for these detergent compositions, the amount of the preservative can be set as small as possible.

When the cation degree is less than 0.1 meq / g, the finger passage when the foam is rinsed may be poor, and the hair after drying may feel dry. On the other hand, when the cation degree exceeds 3.0 meq / g, the storage stability of the cleaning composition may be inferior.

  The molecular weight of the cationized cellulose is preferably in the range of 100,000 to 3,000,000, more preferably 300,000 to 2,000,000. If it is less than 100,000, the finger passage when rinsing the foam may worsen, and the hair after drying may feel dry. On the other hand, if it exceeds 3 million, the storage stability of the cleaning composition may be inferior and dissolution in the cleaning composition may be difficult.

  As specific examples, Leo Guard LP, GP, MGP, XE-511K (trade name, manufactured by Lion Corporation), UCARE LR-30M, JR-400, JR-30M (trade name, Dow Chemical Japan Co., Ltd.) Product), Kachinal HC-100 (trade name, manufactured by Toho Chemical Co., Ltd.), and the like.

As the cationized cellulose and / or cationized guar gum, raw materials obtained by evaporating water to form powders or granules can be used, and raw materials liquefied with a solvent such as water can also be used.

  The component (E) of the present invention is a copolymer of dimethyldiallylammonium chloride and (meth) acrylamide, and can be used singly or in appropriate combination of two or more. In addition, (meth) acrylamide shows acrylamide or methacrylamide. It is a copolymer using dimethyldiallylammonium chloride having a cationic functional group and acrylamide or methacrylamide as monomers, and a binary copolymer of dimethyldiallylammonium chloride and acrylamide or methacrylamide is preferable. As long as dimethyldiallylammonium and acrylamide or methacrylamide monomers are contained in an amount of 70% by mass or more based on the total amount of monomers, other monomers may be included in the constituent units. The ratio of dimethyldiallylammonium chloride: acrylamide or methacrylamide is preferably 1: 9 to 9: 1 by mass ratio, and most preferably 2: 8 to 6: 4. As a cation degree, the range of 0.5 meq / g-3.0 meq / g is preferable, and 1.2 meq / g-3.0 meq / g is more preferable. When the cation degree is less than 0.5 meq / g, the stable dispersion force of the silicone compound may be inferior, and the touch when the foam is rinsed may be inferior. On the other hand, if it exceeds 3.0 meq / g, the stable dispersion of the silicone compound may be inferior.

  The molecular weight is preferably in the range of 100,000 to 3,000,000, more preferably 500,000 to 2,000,000. If the molecular weight is less than 100,000, the stable dispersion force of the silicone compound may be inferior, the finger passage when rinsing the foam may be poor, and the hair after drying may feel dry. On the other hand, if it exceeds 3 million, the storage stability of the cleaning composition may be inferior and dissolution in the cleaning composition may be difficult.

  The cationic degree of the cationic polymer of the components (D) and (E) can be easily calculated if the chemical structure is clear, but even when the structure such as the monomer ratio is unknown, the Kjeldahl method or the like It can be calculated from the measured value of N content. In addition, the cation degree shown by this invention is computed based on the value measured by the nitrogen determination method 2nd method of the general test method of the cosmetic raw material reference | standard which is a Kjeldahl method. In addition, meq / g which is a unit of cation degree indicates the number of milliequivalents of N cation groups per 1 g of a sample.

  The molecular weights of the components (D) and (E) can be measured by a liquid chromatography using a general GPC column by a method for comparison with a polymer having a known molecular weight. The molecular weight of the polymer shown in the present invention is a value measured using GPC-MALLS, and a sample solution diluted with a mobile phase having a pure polymer concentration of about 1,000 ppm was prepared using a TSK-GELA column (Tosoh Corporation).

As a standard product, polyethylene glycol having a known molecular weight was used.

  The total content of the components (D) and (E) is 0.1 to 1% by mass, more preferably 0.2 to 0.8% by mass, based on the total amount of the cleaning composition. When the total content is less than 0.1% by mass, the finger passage during rinsing becomes poor and the amount of the silicone compound adsorbed on the hair is insufficient, and the hair feels after drying is not good. On the other hand, if it exceeds 1% by mass, the silicone compound or the cationic polymer is excessively adsorbed on the hair or the background and gives a sticky feel to those who like a refreshing feeling. For humans, itching may occur due to components adsorbed on the background.

  The mass ratio of component (D) / component (E) needs to be (D) / (E) = 1/9 to 9/1, and preferably 3/7 to 7/3. If the ratio of the component (D) is too low, the fingering of the hair when rinsing the foam is inferior, and if the ratio of the component (E) is too low, the hair feels after drying or the cleaning agent It becomes difficult to keep the dispersed particle size of the silicone compound coexisting in the composition small, and the silicone compound may be excessively and non-uniformly adsorbed on the hair or the background.

The cleaning composition of the present invention can be prepared on the basis of a conventional method, and the pH is 3.0 to 5.5, preferably 3.0 to 5.0. The cleaning composition pH of 3.0 to 5.5 is essential for the component (C) to effectively exhibit antibacterial properties. When the pH is less than 3.0, the stability of the polyoxyalkylene alkyl ether sulfate (A) component is deteriorated, and the cleaning composition is separated. When the pH exceeds 5.5, an effective antibacterial activity cannot be exhibited when the blending amount of component (C) is 0.01 to 0.5% by mass, and a surfactant formed during hair washing Since it is difficult to form a complex with the cationic polymer, it is inferior to the finger of the hair when the foam is rinsed.
In addition, pH can be measured by inserting the electrode of a pH meter into the stock solution of the detergent composition and reading the pH value after stabilization using a method defined in the general test method for cosmetic raw material standards. The liquid temperature is set to 25 ° C.

Sulfuric acid was added to each of the hair cleansing compositions of Examples 1 and 3, and the pH was adjusted to the values shown in Table 3 below to obtain the hair cleansing compositions of Example 11 and Comparative Examples 11-13. About the obtained hair cleaning composition, the external appearance of the liquid when preserve | saved at 50 degreeC for 1 or 2 weeks was evaluated. The results are also shown in Table 3. The container used was 100 mL PET (polyethylene terephthalate) or HDPE (high density polyethylene).

  Separation was observed in all hair cleansing compositions having a pH of less than 3. Since the pH of the liquid after the separation shows a value near 1, hydrolysis of sodium polyoxyethylene lauryl ether sulfate occurs when the pH is less than 3, and the hydrolysis is further accelerated by liberating the acid. Probably separated.

[Test Example 2]
In the hair cleaning composition of Examples 4 and 6, the amount of the component (C) was increased or decreased, or the hair cleaning composition added with antiseptic methyl paraoxybenzoate, the hair cleaning added with sodium hydroxide About the agent composition (Comparative Examples 14-20), the bacteria number test and the use test by three panelists who are aware that the background is sensitive were carried out.

Bacterial count test The bacteria were adjusted to 10 ⁸ to 10 ⁹ cfu / mL with sterile physiological saline containing a cryoprotectant to obtain a suspension, which was used as a test solution for bacteria.
Add 0.2 mL of the bacterial test solution to 20 g of the liquid sample (hair cleansing composition), mix well, and prepare an evaluation liquid mixture at a set temperature (25 ° C. or 40 ° C.). Stored in the dark. Next, according to the viable cell count test of the 14th revised Japanese Pharmacopoeia Microbial Limit Test Method, after passing through the predetermined storage days (after 1, 14 days), 1 g is aseptically collected from the evaluation mixture, Casein, digest, lecithin, and polysorbate 80 were each diluted and mixed in 9 mL of liquid medium. 1 mL of the solution obtained by dilution and mixing was placed in a petri dish and mixed with a soy bean, casein, digest, lecithin, polysorbate 80 agar medium to prepare a sample. The sample was cultured at 30 ° C. for 4 days, and the number of surviving bacteria in the sample was measured.

Three panelists who were aware that the test surface was sensitive were used to evaluate the itchiness of the skin from immediately after use to the next day after using the hair cleaning composition according to the following criteria.
++: Strong itching +: Weak itching −: No itching

  In the examples, the bacteria mixed in the hair cleansing composition were killed, and no itching was observed even in panelists who were aware that the background was sensitive.
