Characteristics
SILICA GEL is a neutral or acid synthetic desiccantproduced by coagulating a colloidal solution of silicic acid. SILICA GEL has micropores of approximately 20 A in diameter and physically adsorbs water vapor. SILICA GEL conforms to JIS-Z-0701, which standardizes theperformance including moisture-adsorbing capacity, and is effective for moisture-resistant packages of a wide variety of products from foods to electronic parts. |

Safety
Indicating blue silica gel is colored by organic pigment,cobalt chloride is not used in our silica gel.
Moreover,SILICA GEL is a chemically stable substance expressed as SiO2. It is extremely safe and approved as a food additive by the FDA. It is not hazardous to the human body even if ingested by mistake. SILICA GEL is not deliquescent (liquefiable by absorption) nor does it change its form, as it physically adsorbs water vapor in its micropores.
※)Cobalt chloride (CAS No.7646-79-9) is classified into following regulation.
IARC(International Agency for Research on Cancer):2B(May cause cancer by inhalation)
Directive67/548/EEC(regulations and administrative provisions relating to the classification, packaging and labeling of dangerous substances):AnnexⅠ
REACH: SVHC(Substance of Very High concern):Annex XIV (candidate list)
