3.1

accelerated stability evaluation

study designed to speed up naturally occurring destabilization processes due to intrinsic or extrinsic factors and which predicts the behaviour over the long term

Note 1 to entry: Typically, physico-chemical, mechanical or thermal procedures are employed.

3.2

real time stability evaluation

study that monitors the state of a product to determine the time course of any alteration to it under reasonably expected conditions of storage and use

Note 1 to entry: Often called “long term test” or “standard stability test”.

3.3

stability

ability of a cosmetic product to resist change or variation of its initial properties over time under stated or reasonably foreseeable conditions of storage and use

Note 1 to entry: See Reference [1].

3.4

stability criteria

deviations from initial properties or behaviour at production state, which are acceptable

Note 1 to entry: See Reference [1].

3.5

stability metrics

properties/parameters of the state or behaviour of a cosmetic product which should be monitored according to demanded, specific product qualities

Note 1 to entry: See Reference [1].

3.6

shelf life

recommended time period that a cosmetic product can be kept after its production, during which the defined quality of the product remains acceptable under expected conditions of distribution, storage, display and usage

Note 1 to entry: See Reference [1].
