Problems solved by technology

The disadvantage of this is that menthol and menthol lactate must be heated to 50-60°C to melt, or dissolved in perfume oil, cosmetic oil, alcohol solvent, before they can be easily added to the formula
The disadvantage of amorphous products is that it is inconvenient to handle, because the product must be poured from the packaging drum and must be heated together with the packaging drum until the product melts
While crystalline products are easy to handle, but there are additional additives in them, which may cause compatibility problems with formula raw materials

Embodiment 1

[0035] Under the condition that the room temperature is 23° C., 50 g of solid menthol and 50 g of solid menthol lactate were put into a beaker, stirred with a stirrer at a low speed for 20 minutes, and the composition became a completely clear liquid. The freezing point of the composition was detected and found to be 8.2°C.

Embodiment 2

[0037] Under the condition that the room temperature is 23° C., 25 g of solid menthol and 75 g of solid menthol lactate were put into the flask, stirred with a stirrer at a low speed, and after 20 minutes, the composition became a completely clear liquid. The freezing point of the composition was found to be 20.5°C.

Embodiment 3

[0039] Under the condition that the room temperature is 23° C., 75 g of solid menthol and 25 g of solid menthol lactate were put into the flask, stirred with a stirrer at a low speed, and after 20 minutes, the composition became a completely clear liquid. The freezing point of the composition was found to be 21.1°C.

Under the condition of room temp. is a liquid form, can be used as freshener, smell regualting agent and perfume in the various products of toothpaste, gargle, perfume, lotion, shave cream, shampoo, deodorant, beverage, chewing gum, tobacco product and medicine product, etc.

Description

technical field [0001] The present invention relates to the application of a kind of menthol and its ester as cooling agent, odor regulator, fragrance, specifically the composition of menthol and menthol lactate, the freezing point of this composition is lower than room temperature, and is liquid form. Background technique [0002] Menthol is a well-known physiological cooling agent that has analgesic, refreshing, and odor-regulating effects when applied to the skin and mouth. As the main component of peppermint oil, menthol has been widely used in food, beverages, toothpaste, mouthwash, cosmetics, detergents, candies, tobacco products and medicinal products. However, menthol has a strong minty taste and a harsh feel that limits its use. [0003] Therefore, there is a need for a cooling agent which has a long-lasting cooling effect without the harsh and unpleasant smell of menthol. [0004] In order to improve these disadvantages of menthol, many esters of menthol have be...
