ABSTRACT

Objective To prepare the sunscreen lipstick in order to prevent UVA and UVB.Methods The ratio of bees-wax,castor oil and liquid paraffin were optimized with the orthogonal test based on viscosity and heat resistance.The spread-able ability,stability and the anti-ultraviolet effect of the optimized lipstick were investigated.Results The best ratio of bees-wax,castor oil and liquid paraffin was 8:5:4(w/w/w).The viscosity of the sunscreen lipstick was appropriate,easy to spread and stable,which was demonstrated the good prevention effect from UVA and UVB.Conclusion The advantages of the prepared sunscreen lipstick included simple preparation,low cost and stable quality.It could be a new type of sunscreen lipstick protecting from UVA and UVB.
