Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a detergent composition, particularly a detergent composition having excellent detergency against dirt such as silicone oil and dirt adhering to contact lenses and having low irritation. Regarding things.

[0002]

2. Description of the Related Art Hair, face and body cleaners are used for the purpose of cleaning dirt on hair and skin and keeping them clean. The main function of these cleaners is surfactants. It is no exaggeration to say that the choice of surfactant governs the quality of the detergent. The main functions that a cleansing agent should have are to suppress excessive degreasing, to have a good cleansing property, to have fine and rich foaming, to be easy to rinse, to be mild without any irritation to eyes and skin. , And the like. Conventionally, anionic, amphoteric and nonionic surfactants have been used as detergents conventionally used in accordance with the intended use. Among them, anionic surfactants are preferred from the viewpoints of detergency and foaming. Has been widely used as the main component.

As the anionic surfactant used as the main component of the detergent, alkyl sulfate salt,
There are various structures such as alkyl ether sulfate ester salt, alkyloylalkyl taurine salt, and acyl amino acid salt, and in particular, alkyloyl alkyl taurine salt and acyl amino acid salt have been widely used in recent years because of their mildness to eyes and skin. Further, these anionic surfactants are often used in the form of sodium salt, and may be used as triethanolamine salt or ammonium salt in order to improve solubility.

[0004]

However, although the anionic surfactants composed of these monovalent counterions show good detergency against dirt such as sebum, hair cosmetics such as hair mousses and foundations. It is not suitable for cleaning silicone oil, which has been widely used in makeup cosmetics such as the above and body cosmetics such as sun oil, and does not have a detergency that can be completely removed. Further, regarding foaming, there is a drawback that it is extremely bad in a situation where dirt such as hydrocarbon oil or silicone oil is present.
As a countermeasure against these, it has been attempted to increase the concentration of the active agent, but it may cause thickening of the system, deterioration of usability, and even irritation to the skin. Although there are some examples in which other surfactants such as nonionic agents are combined, foaming and detergency may be reduced.

This also relates to contact lens cleaners. The stains attached to the contact lens are intrinsic and extrinsic, and the intrinsic stains are lipids and proteins derived from tears. On the other hand, examples of extrinsic stains include cosmetics and hand stains, and removal of silicone oil, which has been widely used in cosmetics in recent years, is an important problem for contact lens cleaning agents.

Further, conventionally, there has been a demand for the development of a contact lens cleaning agent capable of simultaneously satisfactorily removing these endogenous stains and extrinsic stains, and recently, a sodium salt of an anionic surfactant and a non-ionic detergent have been developed. Those which improve the cleaning effect by the combined use of an ionic surfactant (JP-A-57-18).
6733), or a combination of a neutralized product of alkyl ether sulfonic acid or a neutralized product of alkyl ether carboxylic acid with a nonionic surfactant to stably blend an abrasive (Japanese Patent Laid-Open No. Hei 1
No. 172815), a cleaning agent that can remove stains attached to a contact lens when used alone is being studied.

However, JP-A-57-186733
Since the cleaning agent of (1) uses a sodium salt of an anionic surfactant, the wetting on the lens surface was not sufficient and the cleaning effect was slightly low. In addition, JP-A-1-
In 172815, when an alkyl ether sulfonic acid neutralized product is used, there is concern about irritation to the eyes, and its concentration must be limited as much as possible. Also, since it contains an abrasive, rub it with your fingers. There was a risk of damaging the lens surface during the cleaning operation.

The present invention has been made in view of the above problems of the prior art, and one of the objects thereof is an excellent cleaning power against dirt such as silicone oil which is difficult to remove with conventional cleaning agents. And a remarkably low irritant detergent composition. Another purpose is
It is an object of the present invention to provide a contact lens cleaning agent which has excellent cleaning power against intrinsic and extrinsic stains on a contact lens, has extremely low irritation, and does not damage the lens.
