Abstract
A composition for preventing hair loss and promoting hair growth includes: 100 parts by weight of an aqueous colloid solution containing nonionic copper nanoparticles having an average particle diameter (D50) of about 2 nm to about 10 nm; about 1 part by weight to about 10 parts by weight of glycerin; and about 1 part by weight to about 10 parts by weight of a co-solvent, wherein the nonionic copper nanoparticles are present in a concentration of about 2,000 ppm to about 3,000 ppm. The composition has the advantages of not only preventing hair loss but also promoting hair growth.
Claims8
A composition for preventing hair loss and promoting hair growth, comprising:
- 100 parts by weight of an aqueous colloid solution containing non-ionic copper nanoparticles having an average particle diameter (D50) of about 2 nm to about 10 nm;
- about 1 part by weight to about 10 parts by weight of glycerin;
- and
- about 1 part by weight to about 10 parts by weight of a co-solvent,
- wherein the non-ionic copper nanoparticles are present in a concentration of about 1,500 ppm to about 2,500 ppm in the aqueous colloid solution.
A method for preparing a composition for preventing hair loss and promoting hair growth, the method comprising:
- preparing an aqueous colloid solution containing non-ionic copper nanoparticles having an average particle diameter (D50) of about 2 nm to about 10 nm;
- and
- adding glycerin and a co-solvent to the prepared aqueous colloid solution, followed by uniformly mixing the glycerin and the co-solvent with the aqueous colloid solution,
- wherein the aqueous colloid solution is prepared by adding sodium hydroxide (NaOH) to an aqueous copper chloride (CuCl2) solution to generate copper oxide and copper hydroxide in the aqueous solution, and adding hydrazine (N2H4) to the aqueous solution to reduce the copper oxide and the copper hydroxide into non-ionic copper nanoparticles.
