  • Anhydrous antiperspirant compositions formulated as nonaerosol, stick, cream, gel, suspension or solution, usually contain at least one cosmetic oil as a carrier for the particulate sweat-reducing active ingredient, in addition to the sweat-reducing active ingredients, so that the antiperspirant active suspended in the oil does not settle on storage
  • commercially available suspensions, gels, creams and sticks contain a suspending or thickening agent, for gels B hydrophobically modified Hectonte, as they are available, for example, under the trade name Bentone gel from the companies Rheox and Elementis Specialties, in thickening thickening agents such as fatty alcohols and / or waxes
