(28) Procedure:

(29) The cyclopentasiloxane is heated to 65° C. The other ingredients are added (one by one) with the temperature remaining at 65-70° C. The whole (transparent solution) is homogenized for 15 minutes. The perlite is added. The mixture is cooled to approximately 55° C. (a few ° C. above thickening of the mixture) and is cast in sticks. The resulting sticks are placed at 4° C. for 30 minutes. The stick of Example 10 exhibits some white strata. It is observed that the combination of the two polyethylene waxes Performalene 500-L polyethylene and Performalene 400 polyethylene from New Phase Technologies makes it possible to obtain a stratum-free stick containing perlite (Example 11).

(32) Procedure:

(33) The cyclopentasiloxane is heated to 65° C. The other ingredients are added (one by one) with the temperature remaining at 65-70° C. The whole (transparent solution) is homogenized for 15 minutes. The perlite or the superabsorbent polymer is added. The mixture is cooled to approximately 55° C. (a few ° C. above thickening of the mixture) and is cast in sticks. The resulting sticks are placed at 4° C. for 30 minutes.

(34) Effectiveness Test

(35) The stick containing the perlite was compared with the stick containing a superabsorbent, Luquasorb 1003, by 9 individuals. The test was carried out on 5 women and 4 men. Each product was applied to the armpits for 5 days, at a rate of one application per day.

(36) For the men, the perlite stick was preferred since it does not form dry pellets under the arms, unlike the stick containing the Luquasorb 1003 superabsorbent. For the women, it is the perlite stick which emerges as the most effective. It appears that the stick containing the perlite is more effective or more cosmetic than that containing the superabsorbent.

(41) The test is carried out on a panel of 30 women between the ages of 18 and 50 who regularly (every day) use a fragranced, opaque white antiperspirant stick.

(42) The following criteria were evaluated:

(43) Effectiveness against wetness

(44) Effectiveness against perspiration odours
