Description

Scrubbing agent and skin cleansing composition containing said scrubbing agent

The present invention relates to a skin cleansing composition containing the scrubbing agent and the scrubbing agent.

During skin cleansing compositions, and the viewpoint of enhancing the effect of removing dirt on the skin, from the viewpoint of imparting a massage effect to moderately irritating to the skin, various scrubbing agent are blended. Such scrubbing agent, polyethylene beads, walnut shell grains, crystalline cellulose hard scrubbing agent is a hard material scrubbing agent such as a powder is used, among others, polyethylene beads excellent remarkably in the effect is the most commonly .

However, the hard scrubbing agent, although superior effects of massaging and stimulating effect and skin for removing the dirt on the skin, sometimes feel uncomfortable skin irritation or foreign body sensation during use. In addition, there is also a risk of damage to the eyes and the eye at the time of cleaning. Furthermore, in recent years there within the cosmetic industry, a move to shy away from the use of hard scrubbing agents, such as biodegradable no polyethylene beads in consideration of environmental pollution.

On the other hand, the conventional skin cleansing compositions, are also used soft scrubbing agent is a soft material of the scrubbing agent as compared to the hard scrubbing agent. Specifically, agar, polyacrylate, alginic acid salt is used. Such soft scrubbing agent, although excellent in use feeling without uncomfortable skin irritation or foreign body sensation in use, there is a problem poor scrubbing effect.

Up to now, as a form of soft scrubbing agent, paraffin wax, a mixture of candelilla wax, and a plurality of oil base of carnauba wax, techniques using wax capsule encasing an enzyme has been proposed (e.g., see Patent documents 1 and 2). However, in order to prepare such a wax capsule will cause longer time and cost.

In view of the technical background and prior art described above, excellent use feeling without unpleasant skin irritation or foreign body sensation in use, and to thereby exhibit proper scrubbing effect, new scrubbing agent in consideration of the influence on the environment pollution It was an urgent need development of.

JP-8-073344 discloses JP-9-249529 discloses

An object of the present invention is excellent in feeling of use without unpleasant skin irritation or foreign body sensation in use, and to thereby exhibit proper scrubbing effect, containing a scrubbing agent and the scrubbing agent in consideration of the influence on the environment pollution and to provide a skin cleansing composition.

That is, the present invention provides a scrubbing agent which is a hydrocarbon wax particles.

The average particle size of the hydrocarbon wax particles is preferably 100 ~ 1,000 .mu.m.

The hydrocarbon wax particles are preferably selected from the group consisting of petroleum derived hydrocarbon wax particles and synthetic hydrocarbon wax particles.

Further, the present invention provides a skin cleansing composition characterized by containing the scrubbing agent.

The content of the scrubbing agent of the skin cleansing composition in is preferably 0.1 to 30 mass%.

Furthermore, the skin cleansing composition preferably contains a higher fatty acid salt.

Scrubbing agent of the present invention, since it has a biodegradability, but there are no adverse effects on the environment pollution. Also, skin cleansing compositions of the present invention containing the scrubbing agent, as well as excellent scrubbing effect is exhibited an excellent effect to use without feeling unpleasant skin irritation or foreign body sensation during use.

The following describes scrubbing agent and skin cleansing composition containing the scrubbing agent of the present invention.

[Scrub agent]
Scrubbing agent of the present invention is a hydrocarbon wax particles. The hydrocarbon wax particle, linear hydrocarbon (normal paraffin), branched hydrocarbon (isoparaffin), saturated cyclic hydrocarbon (cycloparaffin) is a particle and hydrocarbon waxes major components such as, biodegradable have. That is, that there is no adverse effect on the environment pollution. Incidentally, scrubbing agent of the present invention means that a scrubbing agent consisting only of the hydrocarbon wax particles is characterized by the use of hydrocarbon wax particles as the use of scrubbing agent.

Particle size of the hydrocarbon wax particles is not particularly limited, from the viewpoint of excellent scrubbing effect without unpleasant skin irritation, the average particle diameter is preferably used in the range of 100 ~ 1,000 .mu.m , more preferably 200 ~ 900 .mu.m.

As the hydrocarbon wax particles, for example, petroleum-derived hydrocarbon wax particles, synthetic such as a hydrocarbon wax particles. In the present invention, it is preferable to use at least one selected from the group consisting of petroleum derived hydrocarbon wax particles and synthetic hydrocarbon wax particles. In the present specification, the "petroleum derived hydrocarbon wax particles" may be referred to as "component a1".
