General description
Calcium hydroxide is commonly used in wastewater treatment plants (WWTPs) to adjust pH. Calcium hydroxide has numerous applications due to its strong basic characteristics. Uses include flocculants in water and sewage treatment, a whitewash ingredient, soil improvement, as a lye substitute in non-lye hair relaxers, and in the liming industry to neutralize the acid.
Application
Calcium hydroxide can be used:
- In the pretreatment of technical lignin during the pyrolysis in a fluidized bed reactor to overcome the agglomeration to produce phenolic-rich bio-oil.
- As a catalyst in the pyrolysis of pinewood in a fixed bed reactor.

How can I determine the shelf life / expiration / retest date of this product?
1 answer-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
