Benefits of technology

[0009] Accordingly, the objects of the present invention are to obviate the problems in the prior art and to provide a novel hair tonic composition having superior hair care actions.

Problems solved by technology

In contemporary society, where the percentage of senior citizens in the population is growing and stress is high, there are increasing chances of people being exposed to the danger of hair loss.
While various attempts have been made as explained above, conventional hair tonics have not necessarily had sufficient hair care actions such as prevention of hair loss and promotion of hair growth.
This is probably due to the fact that there are various causes for hair loss or the mechanism of hair growth is extremely complicated.

[0036] Method of Production

[0037] Adenosine was mixed and stirred with 70% ethanol, hydrogenated castor oil ethylene oxide (40 mol) adduct and a part of the ion exchanged water to obtain a solution. The remainder of the ion exchanged water was added to the solution obtained which was again stirred whereby a liquid hair tonic composition 1 was obtained.

Abstract

A hair tonic composition containing adenosine, adenosine 5′-phosphate, and / or an adenosine 5′-phosphate salt as an active ingredient.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is an invention belonging to the field of hair tonics. More particularly, it relates to a hair tonic composition having hair care actions such as a superior hair loss preventing action, hair growth promoting action. The hair tonic composition of the present invention is specifically utilized in the pharmaceutical, quasi-pharmaceutical, or cosmetic fields. [0003] 2. Description of the Related Art [0004] In contemporary society, where the percentage of senior citizens in the population is growing and stress is high, there are increasing chances of people being exposed to the danger of hair loss. [0005] In general, hair loss is believed to be caused by the activation of male hormones in the hair follicles, sebaceous glands, and other parts of the body, the decrease in the flow of blood to the hair papilla and hair follicles, hypersteatosis, abnormalities on the scalp due to production of peroxides...
