WS-23 Safety Information

WS-23 Usage And Synthesis

Chemical Properties	N,2,3-Trimethyl-2-isopropylbutanamide is a white, crystalline powder,which gives a physiological cooling sensation on skin or mucosa. It is mainly used to create cooling and freshness in oral care preparations. The material can be prepared by a Ritter reaction using N,2,3-trimethyl-2- isopropylbutyronitrile as the starting material and alkylating agents such as, for example, borates, carbonates, or phosphates.
Chemical Properties	2-Isopropyl-N-2,3-trimethylbutyramide has a cool, mint–menthol-type odor
Uses	Physiological coolant in foods, beverages, tobacco products, toiletries, cosmetics and pharmaceuticals.
Aroma threshold values	Aroma characteristics at 5.0%: slight cooling impact with little character.
Taste threshold values	Taste characteristics at 20 ppm: high-impacting cooling that lasts on the tongue and palate.
Trade name	Winsense WS-23 (Renessenz).
