Process for applying a cosmetic composition comprising a rotary applicator

Abstract

The invention relates to a process for applying a coating composition on keratin fibers, comprising the following steps: a) application of a base composition on the keratin fibers; then b) application of a coating composition of the base composition on the keratin fibers, the application of the coating composition comprising the driving in rotation of an application member with respect to a gripping member, by displacing the application member on said keratin fibers, the application member being impregnated with said coating composition of the base composition.

 a) application of a base composition on the keratin fibers; then   b) application of a coating composition of the base composition on the keratin fibers, the application of the coating composition comprising the driving in rotation of an application member with respect to a gripping member, by displacing the application member on said keratin fibers, the application member being impregnated with said coating composition of the base composition.   
     
     
         2 . The process according to  claim 1 , wherein the driving in rotation of the application organ is carried out about a longitudinal axis (A) with respect to the gripping member. 
     
     
         3 . The process according to  claim 2 , wherein the application member comprises at least one first row of pins and at least one second row of pins, at least one picot of the second row being arranged axially along the longitudinal axis (A) between two adjacent pins of the first row. 
     
     
         4 . The process according to  claim 3 , wherein the application member comprises a third row of pins, each pin of the first row being axially positioned, along the longitudinal axis (A), at the same position as a pin of the third row. 
     
     
         5 . The process according to  claim 4 , wherein, in projection in a plane perpendicular to the longitudinal axis, each pin of the second row of pins is arranged between pins of the first row and pins on the third row, preferably in the middle of the pins of the first row and pins of the third row. 
     
     
         6 . The process according to  claim 2 , wherein the application member comprises a plurality of rows of pins, each row having at least one axially positioned pin, along the longitudinal axis (A), at the same position as a pin of each one of the other rows of pins. 
     
     
         7 . The process according to  claim 6 , wherein each pin of at least one row of pins is axially positioned, along the longitudinal axis (A), at the same position as a pin of each one of the other rows of pins. 
     
     
         8 . The process according to  claim 3 , wherein the rows of pins extend parallel to the longitudinal axis (A). 
     
     
         9 . The process according to  claim 1 , wherein the application member is made of elastomer. 
     
     
         10 . The process according to  claim 1 , wherein the base composition has a content in dry extract greater than or equal to 35%. 
     
     
         11 . The process according to  claim 1 , wherein the coating composition has a content in dry extract greater than or equal to 40%. 
     
     
         12 . The process according to  claim 1 , wherein the base composition according to the invention and the coating composition according to the invention comprise an aqueous phase, preferably each one comprising at least 30% by weight of water with respect to the total weight of the composition. 
     
     
         13 . The process according to  claim 1 , wherein the base composition and the coating composition comprise at least one surfactant and/or at least one fatty phase. 
     
     
         14 . The process according to  claim 1 , wherein the base composition and the coating composition according to the invention comprise at least one dye. 
     
     
         15 . The process according to  claim 1 , wherein the base composition and the coating composition comprise at least one dye chosen from powder materials, liposoluble dyes and water-soluble dyes. 
     
     
         16 . The process according to  claim 4 , wherein the rows of pins extend parallel to the longitudinal axis (A). 
     
     
         17 . The process according to  claim 5 , wherein the rows of pins extend parallel to the longitudinal axis (A). 
     
     
         18 . The process according to  claim 6 , wherein the rows of pins extend parallel to the longitudinal axis (A). 
     
     
         19 . The process according to  claim 7 , wherein the rows of pins extend parallel to the longitudinal axis (A). 
     
     
         20 . The process according to  claim 2 , wherein the application member is made of elastomer
