Description
Panthenyl ethyl ether (CAS 667-83-4) is the ethyl ether derivative of panthenol, also referenced under the trade names Pantyl and D-Panthenylethylether. It belongs to the provitamin B5 family and carries no assigned E-code. It is catalogued under EC number 211-569-1 with the molecular formula C11H23NO4.
In personal care formulations, panthenyl ethyl ether functions as a humectant by binding water within the stratum corneum, improving skin elasticity and reducing transepidermal water loss. Its increased lipophilicity compared to panthenol enhances penetration into hair fibres, making it a functional conditioning agent in rinse-off hair care products. Pharmaceutical topical preparations use it as a stabilising co-ingredient to support active delivery systems.
Panthenyl ethyl ether is supplied in cosmetic and pharmaceutical grades and falls under REACH registration obligations within the EU. Suppliers typically offer it in drum and intermediate bulk container formats. Procurement teams should confirm grade specification against Ph.Eur. or internal quality standards prior to sourcing.
