• the preparations impart such a high viscosity that the microcapsules remain stably dispersed, i.e. do not sediment over time.
• the term increased viscosity is therefore a to understand such rheology which stabilizes the microcapsules in the aqueous (surfactant) phase ensures.
• Such viscosities are usually (determined according to Brookfield, RVT viscometer, 20 ° C, spindle 1, 10 rpm) above 100 and preferably above 500 mPas, preferably in the range from 200 to 2,000 and in particular 500 to 1,000 mPas.
• Suitable thickeners are all the substances that make up the formulations give correspondingly high viscosity.
• polymeric Compounds are preferably polymeric Compounds, since these are able to form a three-dimensional in the aqueous preparations To build a network in which the microcapsules are stabilized.
• Typical examples are Aerosil types (hydrophilic silicas), polysaccharides, especially xanthan gum, Guar guar, agar agar, alginates and tyloses, carboxymethyl cellulose and hydroxyethyl and Hydroxypropyl cellulose, also higher molecular weight polyethylene glycol mono- and diesters of fatty acids, polyacrylates, (e.g.
