It is clear from the results that after one month of storage and mimicking typical consumer use, the ascorbic acid concentration in bottles A and B decreased only very minimally.
It was concluded that the stability of the lipolife® liposomal solution is very good.
In addition it was also concluded from the test results that opening and using the bottle does not influence Vitamin C content. This means that the product does not easily absorb oxygen from the air when exposed due to the specific way lipolife® is formulated.
In conclusion we establish from this test that it is not necessary to store liposomal products in sachets to maintain stability.
It is more cost effective and easier to dispense with a bottled product such as lipolife® whilst still maintaining quality, stability and efficacy.
In this test we replicated consumer use over one month.
Two different bottles were prepared:
One bottle (A) stored at 20°C and one bottle (B) stored at 4°C.
The bottled products were opened and 50% of the product was poured out.
