Yoshida Shirasu is rare and valuable

Shirasu in general: 

Most of Shiras, volcanic ash soil, is easily found in South Kyushu Island with many volcanoes and some products are made from such Shirasu.

Applications:  heat insulating material, abrasive, roof tile, shirasu ballooon as water cleaning material or as abrasive, block, crystal craft, concret spacer, P-type zeolite as antimicrobial use,

 

Yoshida Shirasu:

Huge volcano eruptions took place repeatedly 300K to 800K years ago and laid thick layers of ashes. Yoshida Shirasu is found only in Yoshida area in Kagoshima city, making it rare and valuable. Tuff bed with off-white in color, is made of fine-grained volcanic glass with even size of particle size. You will not find such in any other place other than Yoshida area.

Impurities have been removed thoroughly by subterranean water for 300K to 800K years and only pure mineral ingredients remain.

“Yoshida Shirasu” with 30-40μm in median size, pure off-white in color, and about 2.4 in specific gravity, making it an environmentally preferable material and is now expected to take place of microbeads, causing enviromental problems.

Applications: Abrasive, absorbent and bulking agent for cosmetic products,

 

 

 

 

 

Tuff bed as found in our company land:

There are volcanic ashes all over Japan and we have extremely rare ashes found only in an area called “Yoshida” in Kagoshima-prefecture located in southern tip of Japan.  Such is called “Yoshida Shirasu” and works as abrasive, absorbent and bulking agent as listed in International Cosmetic Ingredient Dictionary and Handbook, INCI Monograph ID:15535

Huge volcano eruptions took place repeatedly 300K to 800K years ago and laid thick layers of ashes. Impurities have been removed thoroughly by subterranean water since then and only pure mineral ingredients remain.   Nature has accomplished such amazing and extreme refinement.

“Yoshida Shirasu” works as abrasive, absorbent and bulking agent as listed in International Cosmetic Ingredient Dictionary and Handbook, INCI Monograph ID:15535.

Yoshida Shirasu is rich in minerals and eon effect helps to clean off and remove waste in pore and smegma in skin.

Yoshida shirasu is the one of the volcano ash soil for elements, purity, particle size in the world.

Specially treated Yoshida Shirasu carry negative ion to draw waste as well as dead skin cells, both with posive ion.

We have developed a state of art technology to sort, extract and divide particle range size and willing to work with you to provide “Yoshida Shirasu”  that meets your specific requirements.

Processing Sirasu ash soil

We have developed the world best sirasu related proccessing method by using the very special processing machines and equipments.  Besides we have registered our sirasu as Yoshida Sirasu in ICID (International Cosmetic Ingredient Dictionary) for the first time in the world and developed the technology capable to add to all liquid type cosmetics beyond the application limit of sirasu by means of the mineral extracted water obtained from sirasu. The classifying process of sirasu takes approximately 2 hours and it is also possible to get the finer micron sirasu according to the operating time of the pulverizer.

 

The Characteristics Of Sirasu

  1. As it is full of minerals, sirasu promotes the nutrition for the skin and keeps it moisturized
  2. As it has superior adsorptive strength, sirasu shows excellent capabilities to eliminate the bodily wastes in pores and the dead skin cells.

3.The fine particles of sirasu keep the skin bright by means of eliminating dead skin cells.

4.Sirasu makes it possible to expand capillaries and promote the blood circulation. In addition to that, it has the heavy metals detoxifying, purifying, and deodorizying effects.

As much as 71% of Yoshida Shirasu is SiO₂

 

SiO₂ is believed to be an essential component to maintain healthy body.

A lot of attention is recently drawn to SiO₂, as a mineral is believed to support life activity.

SiO₂ is found in every human cell, as many as 60 trillion cells,  in skin, blood vessel, bone, combination organization, hair, lymph gland, lung, muscle, nail, tooth, bronchi and they decreas in the number as we get older.

Recent study indicates that the component makes a strong contribution to human health and more and more research has been done in Europe. Clinical study reveals lack of the compoment is the cause of malady as well as premature senescence.

 

 

 

Please refer to one example of Particle Size by Volume Analysis of Yoshida Shirasu before any processing.

Median particle size is within a range between 30-40μm.

We, meanwhile, have developed a state of art technology to sort, extract and divide particle range size and willing to work with you to provide “Yoshida Shirasu”  that meets your specific requirements.
