Abstract

PROBLEM TO BE SOLVED: To obtain a cosmetic rich in moisture retention, useful for improving dryable chopped skin, by including seawater collected from a depth >=200 meters deeper from the surface of the sea. SOLUTION: Seawater collected from a death >=200 meters deeper from the surface of the sea is treated only by filtration and formulated with a cosmetic. Consequently the cosmetic is mixed with minerals as components required for the skin and applied as it is or improves the dryness of skin by a general use method of cosmetic.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention uses seawater collected from a depth of 200 meters or less (hereinafter referred to as deep sea water).
The present invention relates to cosmetics having an excellent balance of minerals and excellent moisture retention.

[0002]

2. Description of the Related Art Normally, cosmetics are used in which tap water or ground water is sterilized by physical filtration, adsorption filtration using activated carbon, irradiation with ultraviolet rays or heat treatment through an ion exchange resin. By performing such a treatment process, halides in water or other unnecessary ions are removed, but trace metals, which are considered useful for the human body, that is, even mineral components are removed. I have.

[0003] On the other hand, deep sea water is almost sterile because there is almost no growth of living organisms because sunlight cannot enter, and no industrial wastewater or domestic wastewater flows directly into the deep ocean water. The seawater that is different from the inflow of water from the land is collected. This is seawater in composition, contains natural minerals as it is, and is clean water as described above.

However, there are no examples of blending deep sea water in cosmetics, and only a blend of dried seawater or a concentrated seabed mud by a filter press has been used so far. For dried seawater,
Some of the various ions contained as minerals in the drying step volatilize or change in ion form, and the properties are clearly different from the original properties. In addition, mud on the seabed is generally collected in Brittany, France, but it is shallow and contains a large amount of seaweeds and planktons, and therefore contains a lot of bacteria.
In addition, there are many effects of industrial wastewater or domestic wastewater.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cosmetic composition which blends necessary minerals and supplies it to the skin and has excellent moisturizing power while solving the safety of conventional cosmetic compositions. I do.

[0006]

SUMMARY OF THE INVENTION The present invention is a cosmetic composition containing water collected from the deep sea at a depth of 200 meters or less, and containing necessary mineral components in a state similar to nature.

The deep sea water used in the present invention has a depth of 2
It is seawater collected from the deep sea deeper than 00 meters and has not been subjected to any treatment other than the physical filtration process. Alternatively, the water having the required salt concentration can be obtained by using the same seawater that has been subjected to a desalination treatment with an ion-exchange resin or a reverse osmosis membrane. Combination with water is also possible. As an example, Table 1 shows the composition of seawater collected from a depth of 320 meters off Cape Muroto, Kochi Prefecture. This seawater is clearly different from surface water because it contains a larger amount of phosphate ions and silicate ions, which are ions generally called nutrients.

[Table 1]

The deep ocean water of the present invention is known to be effective in improving pathologically dry skin, and is effective as a cosmetic as well as a pharmaceutical application (Nomura et al., Pediatrics, 48, 2215, (1995)). It can be used as a skin humectant.

[0010] Cosmetics in the present invention are quasi-drugs as defined by the Pharmaceutical Affairs Law, such as hair restorer, bath agent,

Lip balms, brushes, bath cosmetics and the like.

In the cosmetic of the present invention, when deep sea water is blended, the blending amount is suitably from 0.00001 to 100% by weight. 100% by weight refers to a case where deep water is used as a lotion or the like without any particular treatment, and can be used as an aerosol product. Further, the deep water may be subjected to a concentration step as required, and may be used in a state where the salt concentration is high, and it is possible to reduce the target blending amount.

Furthermore, it can be used in combination with conventional raw materials for cosmetics, and in particular, the synergistic effect with an oil agent enhances the moisturizing effect of the cosmetic.
