Descrizione generale
12-Hydroxy-octadecanoicacid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl), a pH-independent non-ionic surfactant, is an effective solubilizer and emulsifying agent. It is soluble in aqueous media and polar organic solvents however it is not soluble in apolar solvents. Its structure has 12-hydroxystearic acid (lipophilic moiety) and polyethylene glycol (hydrophilic moiety).
Applicazioni
- 12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) has been used:
- in dissolving dexamethasone (DEX) to intraperitoneally inject the mice to test its grip strength to measure the muscle force
- in roflumilast preparation to treat rabbits and guinea pigs to study the mechanisms and pharmacological sensitivity of ozone-induced hypertussive responses
- to dissolve finerenone for oral application in in vivo-studies
Azioni biochim/fisiol
12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) is mainly used as a solubilizer in parenteral and oral formulations. It is preferred for in vitro screening and in vivo efficacy studies of compounds. 12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) is also used in ophthalmic, macromolecule, suppository, and protein formulations due to its solubilization characteristics and safety profiles. It can form micelles typically ranging from 10-15 nm. 12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) can be used to develop micro-emulsion IV formulations.
Altre note
12-Hydroxy-octadecanoic acid polymer with α-hydro-ω-hydroxypoly(oxy-1,2-ethanediyl) is a non-ionic detergent obtained by reacting 15 moles of ethylene oxide with 1 mole of 12-hydroxy stearic acid.

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

Hi, What is the recommended storage condition for Kolliphor HS 15 and what is the expected shelf life corresponding the storage condition? Thank you!
1 answer-
This product can be stored at room temperature. Products that are robust in nature and extremely stable, in the original unopened container, are not assigned an expiration date or retest schedule. These products will have no dating reported on either the label or the Certificate of Analysis.
Products that are not assigned an expiration or retest date are covered by a warranty period of 1 year from the date of product shipment.
