Description

  The present invention relates to a cleaning material, and more particularly, to a cleaning material that does not contain a thickener and has an appropriate viscosity and improves stickiness.

In order to keep the whole body clean, the sweat and sebum are generally washed away by a shower during bathing. At that time, in many cases, a hair washing agent and a body washing agent are used. For these cleaning agents, fatty acid soap has been used for a long time. However, in recent years, anionic surfactants, particularly sulfate-based anionic surfactants, are widely used as cleaning main components, and particularly sodium lauryl sulfate or the like. POE adducts are often used. This is because 1) it can be used as a cleaning agent in a weakly acidic region, and 2) it does not form a paired ion with calcium ions, and does not form a calcium-paired ion film on the hair. is there.

Many detergents using anionic surfactants or amphoteric surfactants such as amino acid-based or betaine-based surfactants are commercially available, but these are slightly inferior in terms of detergency and foaming, but they are mild. Therefore, it is useful for users who are highly sensitive to stimuli such as sensitive skin (see, for example, Patent Documents 1 and 2).

On the other hand, weakly acidic detergents are used as less irritating detergents (see, for example, Patent Document 3), and in addition, paraoxybenzoic acid esters used as preservatives for ordinary detergents are not blended, It has also been reported that a mildly acidic detergent having a preservative effect can be prepared by blending an acylamino acid and an imidazolinium betaine type surfactant, and less stimulating can be prepared by not blending a preservative (for example, Patent Document 4). reference).

In general, when used in a large amount, the cleaning agent may remain on the skin and cause problems such as dermatitis caused by the remaining fatty acid. It was desired. As another problem, there is a problem of dripping at the time of use, and a problem that the washing agent spreads to a part unrelated to the washing action due to dripping, for example, a problem that flows into the eyes and presents eye mucous membrane irritation. In order to prevent such problems from occurring, it has been a common practice to set the viscosity high to prevent dripping. Usually, to prevent sagging of the cleaning agent during use, the viscosity of the system is adjusted to 1500 to 3000 mPa · s. As a means for such adjustment, use of a thickener is generally used, but a weakly acidic region is used. However, it is very difficult to realize a viscosity sufficient to improve usability. For this reason, there existed a case where solid fat and semi-solid fat were used in combination. However, the use of such solid fats and semi-solid fats often impairs the detergency, and the use of thickeners or the formation of a complex with an anionic surfactant may impair the detergency. That is, it can be said that the development of a means for realizing an appropriate viscosity without impairing the detergency has been desired. Cationized polymers such as cationized guar gum, cationized cellulose, and cationized locust bean hydroxypropyltriammonium salt have high affinity with hair, and the repulsion of the quaternary ammonium structure of the side chain improves combing, The effect | action which gives suppleness to hair is known (for example, refer patent document 5). However, there is no known technique for incorporating an anionic surfactant and an amphoteric surfactant into a cleaning agent.

It is.

The mass ratio of the aforementioned anionic surfactant and amphoteric surfactant is preferably from 3: 7 to 7: 3. Whether it is above or below the upper limit of this ratio, the cleaning ability as a cleaning agent may be reduced. In particular, when the content of the anionic surfactant is the upper limit of the allowable amount, the feeling of use is bad and a sticky feeling is felt. The viscosity can be measured with a commonly used B-type viscometer, and a viscosity of 1000 to 10000 mPa · s (No. 3 rotor, 12 rotations / min) is preferable from the viewpoint of easy handling during use.
