Natural sunscreen compositions and processes for producing the same

Abstract

Disclosed is a natural sunscreen composition comprising extracts of Hedychium spicatum and/or Alpinia galanga containing active sunscreen agents, the sunscreen composition devised to protect the skin from the harmful effects of short wavelength UV B rays and long wavelength UV A rays.

1 . A method of producing a natural sunscreen composition, the method comprising: 
 extracting plant extracts from  Hedychium spicatum  by percolation;    filtering the plant extract, concentrating the plant extract to form a dried mass on a rotatory evaporator under vacuum at optimum temperature; and    combining the dried mass with a cosmetically acceptable carrier to produce a natural sunscreen composition.    
     
     
         2 . A delivery system for topical application, comprising the natural sunscreen composition produced according to the method of  claim 1 , the delivery system comprising creams, shampoos, gels, lotions, soaps, oils, sticks or sprays.  
     
     
         3 . A method of producing a natural sunscreen composition, the method comprising: 
 extracting plant extracts from  Hedychium spicatum  by hot-soxhalation;    filtering the plant extract, concentrating the plant extract to form a dried mass on a rotatory evaporator under vacuum; and    combining the dried mass with a cosmetically acceptable carrier to produce a natural sunscreen composition.    
     
     
         4 . A delivery system for topical application, comprising the natural sunscreen composition produced according to the method of  claim 3 , the delivery system comprising creams, shampoos, gels, lotions, soaps, oils, sticks or sprays.  
     
     
         5 . A method of producing a natural sunscreen composition, the method comprising: 
 extracting plant extracts from  Alpinia galanga  by percolation;    filtering the plant extract, concentrating the plant extract to form a dried mass on a rotatory evaporator under vacuum; and    combining the dried mass with a cosmetically acceptable carrier to produce a natural sunscreen composition.    
     
     
         6 . A delivery system for topical application, comprising the natural sunscreen composition produced according to the method of  claim 5 , the delivery system comprising creams, shampoos, gels, lotions, soaps, oils, sticks or sprays.  
     
     
         7 . A method of producing a natural sunscreen composition, the method comprising: 
 extracting plant extracts from  Alpinia galanga  by hot-soxhalation;    filtering the plant extract, concentrating the plant extract to form a dried mass on a rotatory evaporator under vacuum; and    combining the dried mass with a cosmetically acceptable carrier to produce a natural sunscreen composition.    
     
     
         8 . A delivery system for topical application, comprising the natural sunscreen composition produced according to the method of  claim 7 , the delivery system comprising creams, shampoos, gels, lotions, soaps, oils, sticks or sprays.  
     
     
         9 . A method of producing a natural sunscreen composition, the method comprising 
 extracting plant extracts from  Hedychium spicatum  or  Alpinia galanga  by percolation or hot-soxhalation,    filtering the plant extract,    purifying the extract by crystallization to obtain pure cinnamic acid esters; and    combining the pure cinnamic acid esters thus produced with a cosmetically acceptable carrier to produce a natural sunscreen composition.    
     
     
         10 . A delivery system for topical application, comprising the natural sunscreen composition produced according to the method of  claim 9 , the delivery system comprising creams, shampoos, gels, lotions, soaps, oils, sticks or sprays.
