Chitosan for Cosmetic Use

Cosmetics It is possible to produce chitosans as well as chitosan derivatives with varying chain lengths and diferentiated properties for applications in cosmetics, hygiene, and personal care. The molecular weight of most chitosan products is so high that they cannot penetrate the skin and this is an important advantage that makes it suitable for skin care. These materials include chitosan hydrochloride, chitosan acetate, chitosan lactate, carboxymethyl chitosan, quaternized derivatives, oligosaccharides, and also chitin sulfate and carboxymethyl chitin. They can be dissolved in aqueous solutions or used in solid form. In cosmetics, the specifc properties employed are: cationic (chitosan and hair carry opposite electrical charges), bacteriostatic, fungistatic, antistatic, flm-forming, moisture-retaining (chitosan retains moisture in low humidity and maintains hair’s style in high humidity), and controlled release of bioactive agents. Chitosan is also of great interest in cosmetic formulations because it is compatible with other ingredients such as starch, glucose, saccharose, polyols, oils, fats, waxes, acids, nonionic emulsifers and nonionic water-soluble gums. However, chitosan is incompatible with ionic gums, sulfonated surface-active agents, alkalis, and sulfuric acids. Chitosan and its derivatives can be combined with other hydrating agents, solar flters, and other bioactive products used in the formulations.

Chitosan used in skin care products is currently the senior medicine ingredient used in the makeup, used in pulse light, rf, lattice, fruit acid, such as medical cosmetic surgery, have the effect of natural antibiotic resistance to sensitive and anti-inflammatory, the fast repair basal thermal damage, fast healing, repair skin barrier, and metabolism of chitosan to protect skin to taste with the effect of heavy metals.

The most important is that chitosan is one of the world's most potent compounds for absorbing heavy metals, skin toxins and hormones! Effective metabolism due to long-term makeup residue in the bottom of the skin due to heavy metals, hormones and haze. These wonderful effects make it a mythical status in cosmetic skin repair.

Chitosan used in skin care products is currently the senior medicine ingredient used in the makeup, with in the light, radio frequency (rf) pulse, lattice, acidity and other medical cosmetic surgery have the effect of natural antibiotic resistance to sensitive and anti-inflammatory, the fast repair basal thermal damage, fast healing, repair skin barrier, and metabolism of chitosan to protect skin to taste with the effect of heavy metals.By 2013,there are many skin care product contains chitosan like MedSpa, Channel, estee lauder etc.
