3. A hair conditioning formulation according to claim 2 , comprising from 0.1% to 8% by weight of the at least one aminofunctional polyorganosiloxane of formula (I), based on the total amount of the hair conditioning formulation.
4. A hair conditioning formulation according to claim 2 , comprising from 0.1% to 5% by weight of the at least one aminofunctional polyorganosiloxane of formula (I), based on the total amount of the hair conditioning formulation.
5. A conditioning shampoo comprising
a) 0.05 to 10 wt-%, based on the total weight of the formulation, of at least one aminofunctional polyorganopolysiloxane of formula (I),

R, R 1 , R 2 and R 3 independently from each other are CH 3 , OH or OC 1 -C 4 alkyl,
which contains 0.1% by weight or less of hexamethylcyclotrisiloxane, less than 0.5% by weight of octamethylcyclotetrasiloxane and less than 1.0% by weight of decamethylcyclopentasiloxane
b) 5 to 30 wt-%, based on the total weight of the formulation, of at least one non-ionic, and/or an anionic and/or an amphoteric surfactant,
c) 0.2 to 5 wt-% of at least one thickener,
d) 0-5 wt-% of at least one further additive, and
e) water up to 100 wt-%.
