Say that I want to measure the rheological properties of a cream after 7 days, 24 days, and 75days at 3 temperature degrees and I noticed that the shelf life is decreasing rapidly, what can be done to improve the stability of the formulation?
The factors affecting the shelf life of a cream are the possible interactions between the components, microbial growth, storage condition,choice and use of the type and quantity of preservative etc. So shelf life can be increased by modifying the factors concerned.
