thigmo-, thigm-, thixo- +

An irrational dread of touching or of being touched: Rebecca who suffered from thixophobia had difficulties in having relationships with boyfriends because she had problems with getting very close, kissing, and being caressed, and so she went to a doctor for help!

A reference to or characterized by thixotropy.

Many gels and colloids are thixotropic materials, exhibiting a stable form at rest but becoming fluid when agitated.

A clay that weakens or changes from a semisolid state to a more liquid state when disturbed, and that strengthens or changes to a semisolid state when left standing.

Thixotropy or the property exhibited by certain gels of becoming fluid when stirred or shaken and returning to the semisolid state upon standing.

1. The property, exhibited by certain gels, of becoming fluid when shaken or otherwise agitated and then becoming semi-solid again at rest or resuming the gel state when standing.
2. In physical chemistry, a structural property that causes certain gels to liquefy when subjected to vibratory forces; such as, ultrasonic waves or even simple shaking, then to solidify again when left standing.
3. The property of certain gels of becoming less viscous when shaken or subjected to shearing forces and returning to the original viscosity upon standing.

Viscosity refers to the property of a fluid or semi-fluid that causes it to resist flowing as a thick and sticky consistency or quality.

4. Etymology: from Greek thigma, thixis, "touch" plus trope, "turning".

Thixotropy literally means, "turning through touch".
