What is N-Stearoyl-phytosphingosine?
Description
N-Stearoyl-phytosphingosine (SPS), sphingolipids frequently found in mammalian skin, plants, and yeast, have been used in cosmetics. In mice, treatment with SPS inhibited histamine-induced scratching behavior and vascular permeability. This agent inhibited the expression of the allergic cytokines IL-4 and TNF-a and the activation of the transcription factors NF-jB and c-jun in histamine-stimulated skin tissues[1].
The Uses of N-Stearoyl-phytosphingosine
An intercellular lipid that benefits skin hydration and protects against SLS irritation.
What are the applications of Application
N-Stearoyl Phytosphingosine is an intercellular lipid
Definition
ChEBI: N-octadecanoyl-4-hydroxysphinganine is a phytoceramide in which the ceramide N-acyl group is specified as octadecanoyl (stearoyl). It is a N-acylphytosphingosine and a N-stearoyl-sphingoid base.
