SDS/hazardous substance information

Information such as SDS (Chemical Substance Safety Data Sheet) related to products handled by our company, inspection results of harmful substances complying with regulations such as RoHS, CPSC, EN71, etc. is released at any time.
Regarding our approach to the problem of hazardous substances including lead,hereto see the available categories of products and services.
SDS Information Eco Cairo
This is an SDS (in English) regarding the sodium acetate aqueous solution that is the content of the eco-warmer.
Hazardous substance inspection result information by material of our products and by product (mainly for vendors)

Note) Click the blue letters in the table to see the details.
*1:
In the analysis of EN71 Part3, it is the result of the elution inspection of the plated products.
(Please note that it is not a cloth)
In other words, it was found that even products that contain a lot of lead can meet the EN71 Part 3 standard, which is assumed to be swallowed, even for products that are plated on the surface, which are normally sold in the market.
*2:
CPSC's CPSIA (Consumer Product Safety Improvement Act) regulates lead content for children under 12 years of age.
Paint and surface coating90ppm or less
Other than paint and surface coating100ppm or less

The unit of the numbers in the table is ppm (1000ppm=0.1%)
"ND" in the table indicates less than the lower limit of quantitative measurement
"---" in the table indicates that it is not subject to inspection (since metals theoretically do not include PBBs and PBDEs)
*1:
In the analysis of EN71 Part3, it is the result of conducting a lead elution test for products with plating.
(Please note that it is not all 8 elements and it is not the fabric)
In other words, it was found that even products that contain a lot of lead can meet the EN71 Part 3 standard, which is assumed to be swallowed, even for products that are plated on the surface, which are normally sold in the market.

Rubber cast product group (handling warning)
We will publish the analysis results of heavy metals including lead in rubber cast products.
Rubber casting is a method in which a lead alloy of tin is melted, poured into a rubber mold that rotates at high speed, and centrifugally cast.
Since it uses rubber, it is an alloy that can be handled at low temperature at low cost and has been widely used since ancient times.
However, since the raw material is an alloy of tin and lead, the corresponding raw material contains lead.
In the accessories and metal miscellaneous goods industry, even the same alloys are roughly classified into two according to their mixing ratio and used properly.
- High meta:
- High tin content and low lead content...
It is light and durable, and it is easy to express detailed details, but the unit price is high - Low meta:
- Low tin content and high lead content...
It is heavy and fragile, and it can not produce detailed details, but the unit price is cheap
From the above characteristics, low metal tends to be used for inexpensive metal miscellaneous goods and high metal for expensive accessories.
We have received an analysis table of the raw materials currently used from our cooperating factories.
Cast metal analysis table
Even high-metal contains 5% lead, and low-metal contains more than 50% lead.Do not let infants lick, put in mouth, swallow, etc.Adults should handle with care.
Used by usRubber cast product example
Normally, it is not sold in the form of cloth, and since the surface is plated (nickel plating, etc.), it is unlikely that it will come into direct contact with lead. It seems that you need to be careful.
Machined product group of ground products (handling)
Among the sawed parts used in our company, about the mobile strap parts (pine needles) that we surveyed this time, improve the machinability to brass (brass: alloy of copper and zinc) that is the raw material of the metal part (saved parts) Therefore, it was found that the lead contained 1.869%.
Mobile phone strap parts Analysis result 1 Analysis result 2 Analysis result 3
Since the surface is plated (nickel plating or gold plating), it is unlikely that it will come into direct contact with lead.Do not let infants lick, put in mouth, swallow, etc.Adults should be careful in handling.
Bead Netsuke Series (Handling Caution)
Of the bead netsuke series sold by our company, we received a report that we detected a trace amount of lead when we asked a manufacturer overseas to analyze and analyze cat's eye style beads.
In response to this, we conducted a domestic analysis and research on the following bead roots (cellular straps) that we handle, and confirmed that all of the lead contents are below the standard value except for cat's eye bead roots. ..
Regarding cat's eye bead netsuke,Do not let infants lick, put in mouth, swallow, etc.Please be careful when handling by adults.

The amount of lead contained in the materials used in the product is extremely small and is within a range that does not pose a problem.
Zinc die casting is a method in which a zinc alloy is melted and poured into a mold at high pressure for casting.
Zinc alloy is an alloy whose main raw material is zinc, and casting means casting.
