As far as the SubChem cases are concerned, this theory is cortfirmed in the case of cooling lubricants, mould release agents and metal cleaning. 

Loss of torque against time has been well documented with plastic caps on plastic bottles. This does not necessarily mean that the closure becomes ineffective, but there are occasions when a low torque only needs the vibration effects of transportation to become an unsatisfactory (loose/leaking) closure. Certain tamper-evident/resistant features such as sealed diaphragms and ratchet-type closure systems are likely to overcome such problems. Having the right combination of plastics may also eliminate or reduce this loss of torque. However, there is the converse where the use of the incorrect combination of plastics, or plastics with undesirable constituents such as lubricants, mould release agents, internal release agents, may actually exacerbate the loss of closure torque. This loss may be associated with thread forms, area of thread contacts, cold flow or creep of plastics involved, lubricants, etc. 

Sustainable external lubricants (mould release agents) are mainly waxes, such as bee wax, Carnauba wax and rapeseed oil, where boiling points are critical [35]. As long as the boiling point of the sustainable external lubricant is not lower than the processing temperature of the melt, it can be considered to be a good candidate.
