[0111] The alcohol-in-oil emulsions of the present invention are unique in that they are stable despite high levels of ions and / or electrolytes. Therefore, the alcohol-in-oil type emulsions of the present invention have utility whenever a stable emulsion containing high levels of ions is desired. Therefore, alcohol-in-oil emulsions containing high levels of ions can find applications in paint or cosmetic products such as antiperspirants, shampoos or body lotions.

[0112] Generally it is understood from the above description that alcohol-in-oil emulsions can be used as antiperspirants.

[0113] That is, in one embodiment, a alcohol-in-oil emulsion can be used as an antiperspirant for reducing perspiration.

[0114] This reduction in perspiration can be obtained under the arms, hands, under or on the feet of a person.

[0115] As a result of their use as antiperspirants, alcohol-in-oil emulsions can be used to reduce undesirable body odor.

[0116] In particular, alcohol-in-...

Embodiment 1

[0120] Alcohol-in-oil emulsions containing active aluminum salts and aluminum buffer salts were prepared.

[0121] Amount, wt%

[0122] A weighed amount of excipient 1) is placed in the container. Excipient 2) was added with brief stirring for 40 seconds at 23°C. Excipient 3) was added with brief stirring for 40 seconds at 27°C. Excipient 4) was added with brief stirring for 30 seconds at 28°C. Excipient 5) was added with stirring for 3 minutes and 40 seconds while increasing the temperature to 39° C., when the desired temperature was reached, stirring was stopped. Keeping the mixture for a short time, the mixture of excipients 1) to 5) has consistency between cream and lotion. The metal salt 6) and the solvent 7) were mixed for 3 minutes at 20° C. to obtain a suspension of the metal salt in the solvent. The mixture of excipients 1)-5) was carefully added to the suspension of 6) and 7) with stirring at 22°C for 3 minutes to provide the final mixture of excipi...

Embodiment 2

[0124] pH value and conductivity of alcohol-in-oil emulsion containing active aluminum salt and aluminum buffer salt

[0125] A mixture of alcohol-in-oil emulsion and water was provided, and the pH and conductivity of the resulting mixture were tested.

[0126] The results obtained are listed in the table below:

Abstract

The present invention relates to emulsion science, especially within the area of alcohol-in-oil type emulsion, where the level of ions comprised in the alcohol-in-oil type emulsion is relatively high. In particular, the invention relates to a stable alcohol-in-oil type emulsion comprising a multivalent metal salt that may act as an antiperspirant.

Description

technical field [0001] This invention relates to the field of emulsion science, and in particular to providing stable alcohol-in-oil emulsions containing substances that provide high levels of electrolytes. Typically, high levels of electrolytes are obtained by adding polyvalent metal salts to alcohol-in-oil emulsions. Background technique [0002] Perspiration, or sweating, is a completely natural physiological process that an animal's body goes through, and many people sweat more than they realize. Surprisingly for most people, the average person produces 1 / 2 to 1 liter of sweat per day. [0003] Human sweat itself is largely odorless. The main cause of body odor is that microorganisms reproduce in a hot, humid environment, such as in the human armpit, which has a high density of sweat glands and is relatively closed, which may be caused by excessive sweating. On the body surface of the human body, the armpits are always the hottest areas, and the sweat glands provide m...
