I think the uneven repulsion is because milk is a mixture which contains many different substances with different chemical properties. Non polar substances which has the geometry to pile up easily, form hydrogen bonds with themselves easily and doesn't interact with polar substances are hydrophilic. Milk is a mixture of substances of different polarities and masses. Due to different substances in the mixture having different mass each molecule will respond differently to the same force. Because of difference in polarities some substances may interact with the substance brought into milk differently which causes further disturbance
