Product Description of Potassium phosphate
Product Description of Potassium phosphate CAS#778-53-21-Ethyl-2-pyrrolidone is a compound capable of boosting transdermal absorption, and its effects on multilamellar liposomes formed by stratum corneum lipids have been researched.
N-Ethyl-2-pyrrolidone is extensively adopted as a solvent. Its low boiling point renders it fit for use under low-illumination and constant-pressure environments. Additionally, it acts as an intermediate for polycarboxylic acid synthesis and takes part in processes concerning viscosity regulation and hydrogen bonding interactions.
N-Ethyl-2-pyrrolidone (NEP) is a transparent, colorless liquid. It serves as a low-volatility aprotic solvent and is categorized as a reproductive toxicant. It exhibits powerful solvency capacity, low vapor pressure and a low dielectric constant.
Neurotoxin – Linked to Acute Solvent Syndrome.Occupational hepatotoxin – Recognized as a secondary hepatotoxin; potential toxic impacts have been detected via occupational exposure or animal tests involving ingestion and experimental intoxication.
Reproductive toxicant – A substance hazardous to the reproductive system, which may trigger developmental disorders or compromise reproductive functions in both males and females.
