Physiological coolants have been around for decades, the most well-known being menthol. The GREEN SPRING® line offers unique odorless and flavorless cooling sensations which can be used alone or as a complement to menthol to help extend the cool fresh feeling in the final application, or in fruit flavors to enhance juiciness perception. The low volatility of these compounds allows for skin contact without a burning sensation in the eyes. In order to satisfy today's customers who demand specific sensory experiences, the need exists for physiological coolants to provide intense and memorable sensations.

WS-3

Cyclohexanecarboxamide,N-Ethyl-5-Methyl-2-(1-Methylethyl)-

 

WS-3 is a menthol derivative. But unlike menthol, WS-3 is virtually nonvolatile, odorless and tasteless. WS-3 is one of the most used cooling agents in the market and it's known for its clean immediate cooling impact and has been found to cool primarily at the roof of the mouth, the back of the mouth and the back of the tongue.

WS-5

N-(Ethoxycarbonylmethyl)-3-p-menthanecarboxamide

 

WS-5 is a menthol derivative that was developed in the 1970s by Wilkinson Sword, but was not commercialized due to a bitter aftertaste associated with the product. However, we have developed a patented process to offer substantially pure WS-5 that does not possess the bitter aftertaste present in previous forms of the product. WS-5 has been found to have approximately two and one-half times the cooling intensity of WS-3, it is one of the strongest commercially available coolants, yet exhibits a smooth and round flavor profile. WS-5 has been found to cool primarily at the roof of the mouth and the back of the tongue.

WS-12

(1R,2S,5R)-N-(4-Methoxyphenyl)-5-methyl-2-(1-methylethyl)cyclohexanecarboxamide

 

WS-12 is a menthol derivative. But unlike menthol, WS-12 is virtually nonvolatile, odorless and tasteless. WS-12 offers one of the strongest initial cooling impacts and a significantly longer lasting effect comparing with such conventional coolants such as WS-3, WS-5, and WS-23. It has potential for use in mint flavors in oral care applications as well as confectionary and chewing gum depending on dosage levels. In addition it can be used at low levels to impart freshness into berry, citrus and other fruit flavors in a variety of applications. WS-12 has been found to cool primarily at the front of the tongue.

WS-23

Butanamide, N,2,3-trimethyl-2-(1-methylethyl)-

 

WS-23 is not derived from menthol. But like WS-3, it exhibits little or no odor or taste and has a low volatility. Sensory evaluations of WS-23 indicate that the product cools more in the front of the tongue and mouth. While the product has somewhat less cooling impact than that of WS-3, the cooling profile is more round and smooth in character.

WSE-500

WSE-500 is a proprietary, liquid blend of cooling agents. This easy to incorporate material allows for manufacturers to avoid issues that result from insufficient mixing of solids.

Menthyl Lactate

Propanoic acid, 2-Hydroxy-,5-methyl-2-(1-methylethyl) cyclohexyl ester

 

Menthyl Lactate is also a menthol derivative. The product has a mild mint-like character, with a fresh and invigorating profile. In addition to use in flavor applications, the product is also widely used in cosmetics and personal care applications. Our product is offered in fused form.

Cooling Intensity
 

We have evaluated two basic attributes of cooling agents: cooling at onset and cooling longevity. Sensory attributes of coolants were evaluated at 20 ppm in ethanol. Menthol was used as a reference in measuring the overall cooling intensity. WS-5 has been found to have approximately four times the cooling intensity of menthol. The desired intensity of sensory perception and duration will depend on factors such as coolant concentration, flavor interactions and other formula attributes.
