Cooling agent WS-23, chemical name N,2,3-trimethyl-2-isopropylbutyramide, is a highly effective and safe synthetic cooling agent. It has the following characteristics:
Cooling effect: WS-23 provides a cooling effect similar to menthol, but without side effects such as burning, numbness and irritation.
Physical form: It is a white crystalline powder.
Solubility: WS-23 is almost insoluble in water, but soluble in alcohol and oil.
Application areas: Widely used in food, beverages, candy, cosmetics, tobacco products, medicine and other industries.
Synergistic effect: When used with flavors, WS-23 can produce good compatibility synergy and significantly enhance the flavoring effect.
Safety: In GB 2760, WS-23 is listed as a food flavoring, which is allowed to be used in food, and there are clear maximum allowable usage and residual standards.
Production and sales: WS-23 is produced and sold by many companies, such as Jiangxi Yuanshangcao Spice Co., Ltd., Ningbo Kunjue Pharmaceutical Technology Co., Ltd., etc., providing products with different purity and packaging specifications.
Market situation: According to market research, the global cooling agent WS-23 market sales reached RMB 610 million in 2023 and is expected to reach RMB 870 million by 2030, showing a steady growth in market demand.
Chemical properties: The molecular formula of WS-23 is C10H21NO, the molecular weight is 171.28, the CAS number is 51115-67-4, and the EINECS number is 256-974-4.
Preparation method: There are many preparation methods. A simple method is to generate an intermediate through the alkylation reaction of propionitrile and 2-bromopropane, and then synthesize WS-23 through an amidation reaction.

The efficacy and role of the cooling agent WS-23 in toothpaste are mainly reflected in the following aspects:
Cool taste: WS-23 has extremely high cooling activity, can provide a refreshing and lasting cooling feeling, and does not have the bitterness and spiciness of menthol.
Long-lasting effect: Compared with other cooling agents, the cooling effect of WS-23 can last longer, such as more than 30 minutes, providing a long-lasting cooling feeling to the mouth.
High temperature stability: WS-23 can still maintain a cooling effect at high temperatures (such as 200°C) and is not affected by high temperatures, which makes it suitable for products that may undergo high-temperature processes such as toothpaste.
Improved taste: WS-23 can solve the problem of bad taste in toothpaste and give the product a more pleasant cooling feeling.
Low dosage: The dosage of WS-23 is low, and the generally recommended dosage is 30-100ppm to achieve the ideal cooling effect.
Synergistic enhancement: It is recommended to use WS-23 with flavors, which can produce good compatibility synergy and enhance the aroma of toothpaste.
Safety: WS-23 has no irritating effect on the oral mucosa and throat, and is suitable for oral care products.
Solubility: WS-23 is almost insoluble in water, but soluble in alcohol and oil, which helps to mix the ingredients in the toothpaste formula.
Scope of application: In addition to toothpaste, WS-23 is also suitable for other oral care products, such as mouthwash, oral spray, etc.
Product form: WS-23 is usually provided in the form of white crystalline powder, which is convenient for mixing and use in the toothpaste production process.
