Embodiment 1

[0046] The aerosol stock solution was prepared according to the ratio listed in Table 1, and the propellant was liquefied petroleum gas, which was packed into an aerosol container according to the weight ratio shown in Table 1 to obtain an aerosol composition. In addition, the polyoxyethylene hydrogenated castor oil used the product of the trade name Nitsukoll HCO-50 (POE50) produced by Nikko Chemicals.

Abstract

The invention provides aerosol-type refrigerant which has a good cooling effect and a long duration. The refrigerant is a aerosol combination, which includes 50-99.9 wt.% water, 0-40% wt. lower alcohol, 0.05-5 wt.% surfactant, a mixture of 0.05-5 wt.% aerosol stock solution (A) and a gas ejecting agent (B) selecting at least a component from a set of matter consisting of LPG and dimethyl ether, wherein (A):(B)=15:85-50:50 wt.%.

Description

technical field [0001] The present invention relates to aerosol compositions producing a sustained cooling effect. Background technique [0002] When injuries such as bruises and sprains occur after sports, in order to achieve the purpose of cooling the injured parts of the body, aerosol coolants are used. [0003] As such coolants for the body, for example, liquefied gas or liquefied gas and a low-boiling coolant are packaged in an aerosol container and sprayed onto a certain part of the body to volatilize the volatile components. The part of the body is cooled by virtue of the latent heat of vaporization at this time. However, in such coolants, since the retention time of the volatile components on the body is short and the effect duration is short, there is a disadvantage that the cooling effect is small. [0004] It is also known that a cooling agent with a longer cooling time, containing an aqueous stock solution for aerosols and a propellant for aerosols with a boili...
