Melt/Freeze Pt:=169.C, 336.2F
Spec Gravity:1.44 (H*2O=1 @ 4C)
pH:OTHER INFO
Solubility in Water:4.7% @ 20C; 27.5% @ 100C
Appearance and Odor:WHITE GRANULAR OR POWDER SOLID; ODORLESS.

Stability Indicator/Materials to Avoid:YES
BORIC ACID REACTS AS A WEAK ACID WHICH MAY CAUSE CORROSION OF BASE
METALS. REACTION WITH STRONG REDUCING AGENTS SUCH AS METAL HYDRIDES
OR ALKALI METALS WILL GENERATE HYDROGEN GAS WHICH COULD CREATE AN
EXPLOSIVE HAZARD.
Stability Condition to Avoid:FORMS PARTIAL HYDRATE IN MOIST AIR. WHEN
HEATED, WATER IS LOST FORMING METABORIC ACID (HBO*2). ON FURTHER
HEATING, THE MATERIAL IS CONVERTED BORIC ACID (B*2O*2).
Hazardous Decomposition Products:NONE KNOWN.

Waste Disposal Methods:SML AMTS OF BORIC ACID CAN USUALLY BE DISPOSED
OF AT MUNICIPAL LANDFILL SITES, & REQUIRES NO SPECIAL TREATMENT.
TONNAGE QTYS ARE NOT HOWEVER, REC FOR LANDFILL, & IF POSS SHOULD BE
REUSED FOR APPROP AP PLICATION. REFER TO STATE & LOC REGS FOR
APPLIC SITE-SPECIFIC REQS. BORIC ACID IS NOT CURRENTLY LIST ED
UNDER ANY SECTIONS OF U.S. (TRANSPORT INFO)

Toxicological Information:EYES: BORIC ACID, WHEN APPLIED TO EYES OF
ALBINO RABBITS (DRAIZE TEST), PRDCED EFTS OF MILD ERYTHEMA, & MILD
TO MOD DISCHARGE IN 5 OF 6 RABBITS. ALL SIGNS SUBSIDED BY 4TH DAY
AFTER APPLICATION. FIFTY YRS OF OCCUP EXPOS HISTORY INDICATES NO
HUMAN EYE INJURY FROM EXPOS TO BORIC ACID. SKIN: BORIC ACID WAS
APPLIED TO SKIN OF ALBINO RABBITS. SLIGHT TO NO IRRIT PERSISTED 72
HRS AFTER APPLICATION. NO EVI DENCE OF TISS DMG WAS FOUND. LOW
