Abstract
A stick shaped lipstick composition which comprises a higher loading of cosmetic powders than those available in prior art compositions is disclosed. The composition includes between about 10% and about 65% of at least one cosmetic powder. At least one low viscosity liquid carboxylic acid ester, present in a concentration of between about 10% and about 65%, is also included. A third component of the composition is at least one high viscosity surface oil included in an amount of between about 1% and about 18%. The composition additionally comprises between about 2% and about 15% of at least one plasticizing agent. All of the above mentioned percentages are by weight, based on the total weight of the composition. The high concentration of cosmetic powder provides a unique finish, texture and feel lipstick heretofore unavailable in convenient stick shape.
