Hello,
I see that my soap formulation lost 0.6% of total non-volatile solids over 6 months while it was stored at the stability chamber. Chamber holds the temp. between 24 - 25 degrees Celsius and R.H. between 59 - 62%. The other parameters of the soap like pH, viscosity, specific gravity are stable over time. Mass loss is appr. 1% over the time of 6 months, so why low % of total non-volatile solids? Does anybody have any suggestions?
Thank you,
