Potassium Hydroxide KOH for liquid soap making and demanding biodiesel manufacture. High quality, food grade. 90% Pure Flakes. Synonyms: Caustic potash; potassium hydrate.

Per Container: 1 lb of Potassium Hydroxide (KOH) Flakes packaged in a safety-sealed, HDPE bottle with a resealable lid.

Manufactured by the electrolysis of a potassium chloride (KCI) solution using membrane electrolytic cells (but non mercury based). Chlorine and Hydrogen are formed from the electrolytic production as co-products.

U.S. Consumer Product Safety Commission tested and approved: KOH, container, cap, label, plastic bag, shipping packaging, and transportation.

ODOR/AROMA: Odorless in its dry state.
NUTRITION: No nutritional value.
SOLUBILITY: freely dissolves in water with agitation under proper conditions. Without agitation, the flakes will fall to the bottom and form a layer of hydrate, which will dissolve but very slowly
pH: Not Applicable, will form a significant amount of salt when neutralized
Hygroscopic: yes
Explosive - not explosive
Flammability - not flammable
KOSHER: Kosher Certified product re-packed into containers.

HALAL: Not certified, however, it does not contain alcohol, natural L-cysteine extracted from hair or feathers, animal fats/extracts, blood, blood plasma, or meat. Alcohol is not used as processing aid. May be acceptable for Halal consideration.

BEFORE HANDLING, it is important that engineering controls are operating and protective equipment requirements and personal hygiene measures are being followed. People working with this chemical should be properly trained regarding its hazards and its safe use.

WHEN HANDLING, refer to the Safety Data Sheet and Product Warning Label and follow all instructions and warnings. The creation and dilution of solutions produces considerable heat and may cause boiling, spattering, or violent eruption. Workers should be properly instructed in dilution procedures and exercise caution. Incompatibilities: Flammable liquids, Water, Acids, halogenated compounds, certain metals including aluminum, brass, bronze, copper, lead, tin, zinc, and their alloys and other alkali sensitive metals. Therefore, containers or tools of those materials are NOT suitable for handling or storing Potassium Hydroxide. Aluminum will quickly corrode generating flammable hydrogen gas. Plastics, such as polyethylene, polypropylene, PVC, and CPVC, can be used (without silica) as they are chemically compatible if you adhere to the plastics maximum temperature limitations.

The United States Occupational Safety and Health Administration (OSHA) and the American Conference of Governmental Industrial Hygienists (ACGIH) have established or recommended occupational airborne exposure limits. The established Ceiling Limit should not be exceeded during any part of the working exposure.

STORAGE: Recommend use of the air tight shipping container to minimize any product agglomeration in the package.
