D-Panthenol is regarded as multi-active ingredient for cosmetics thanks to its physio-chemical properties in: *Penetrating relatively deep into the skin *Water binding and/or water retention *Being transformed to pantothenic acid in skin and hair after topical administration creating pro-vitamin B5 activities.  D-Panthenol may be regarded as ideal cosmetic ingredient which may improve skin and hair care as well as protect against   environmental stress. The cosmetological actions of  D-Panthenol are based on following findings: *Improvement of the mitotic activity (cell regeneration) *Acceleration of epithelisation and granulation after burns, eczemas ulcerations, radiotherapy and plastic surgery. *Improving symptoms of inflammations . *Strengthening of hair roots and hair shafts. *Protection against ammonia produced napkin rash.
