Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 266-047-6 | CAS number: 65997-18-4 Frit is a mixture of inorganic chemical substances produced by rapidly quenching a molten, complex combination of materials, confining the chemical substances thus manufactured as nonmigratory components of glassy solid flakes or granules. This category includes all of the chemical substances specified below when they are intentionally manufactured in the production of frit. The primary members of this category are oxides of some or all of the elements listed below. Fluorides of these elements may also be included in combination with these primary substances.@Aluminum@Manganese@Antimony@Molybdenum@Arsenic@Neodymium@Barium@Nickel@Bismuth@Niobium@Boron@Phosphorus@Cadmium@Potassium@Calcium@Silicon@Cerium@Silver@Chromium@Sodium@Cobalt@Strontium@Copper@Tin@Gold@Titanium@Iron@Tungsten@Lanthanum@Vanadium@Lead@Zinc@Lithium@Zirconium@Magnesium

Description of key information
Studies were performed according to UN Transport of Dangerous Goods Recommendations, Fourth Revised Edition (Class 8, Packing 8, Packing group III, test C1) on corrosivity to metals; and according to UN Recommendation on the Transportation of Dangerous Goods, Manual of Tests and Criteria for substances of Class 4, Division 4.3, on the emission of flammable gases on contact with water were conducted.
The percentage mass losses on steel and aluminium were found to be < 13.5 % over 7 days, however the maximum pit depth on the aluminium coupns was > 120 μm. The saturated solution of boric acid was therefore a candidate for classification as a corrosive substance of UN Class 8, Packing group III ( according to the UN Transport of Dangerous Goods Recommendations).
Studies on dustiness were performed according to CIPAC method MT 171 and showed that boric acid granular was dust category 1 - nearly dust free; boric acid TP was dust category 2 - essentially non-dusty and boric acid powder was dust category 3 - dusty.
Additional information
A study performed according to UN Transport of Dangerous Goods Recommendations, Fourth Revised Edition (Class 8, Packing 8, Packing group III, test C1) on corrisivity to metals showed that the percentage mass losses on steel and aluminium were found to be < 13.5 % over 7 days, however the maximum pit depth on the aluminium coupons was > 120 μm. The saturated solution of boric acid was therefore a candidate for classification as a corrosive substance of UN Class 8, Packing group III ( according to the UN Boric acid did not emit flammable gases on contact with water. Transport of Dangerous Goods Recommendations).
It was determined that a fully saturated solution of boric acid in water should be classified as not a material of Class 4.3 according to the UN recommendations on the Transportation of Dangerous Goods.
Studies on dustiness were performed according to CIPAC method MT 171 and showed that boric acid granular which has a particles size (d50 mm) of 0.608 was dust category 1 - nearly dust free. This sample represents the most representative of those placed on the market.Boric acid TP, which has a particle size (d50) of 119 μm was dust category 2 - essentially non-dusty.
Boric acid powder, which has a particle size (d50 mm) of 0.051 was dust category 3 - dusty. This sample represents the finest grade placed on the market.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
