Antiperspirant compositions

Anhydrous antiperspirant compositions containing an encapsulated fragrance, in which the encapsulate shell comprises an aminoplast resin, and preferably a melamine/formaldehyde resin. The encapsulates have a weight average particle diameter in the range of 25 to 60 μm, a shell having a measured thic...

Zusammenfassung:	Anhydrous antiperspirant compositions containing an encapsulated fragrance, in which the encapsulate shell comprises an aminoplast resin, and preferably a melamine/formaldehyde resin. The encapsulates have a weight average particle diameter in the range of 25 to 60 μm, a shell having a measured thickness in the range of from 1 to 10 μm and an average in the range of from 5 to 8 μm, a ratio of the shell thickness to the average particle diameter in the range of from 1 :5 to 1 :10 and a Hysitron hardness in the range of from 2 MPa to 50 MPa, particularly 15 to 25 MPa, enabling them do be advantageously employed in the anhydrous antiperspirant compositions.
