Thank-you everybody for the feedback, has been really helpful. I am going to reduce the glycerine. In terms of the some of the questions raised. 
Perry - I have done some homemade stability testing, one jar has been in a hot water cupboard for around 10 weeks and still looks and feels good. If I did lower the glycerine, what acid and percentage should I use? (I’m about to get a pH meter which will help)? 
Bleassi:  agree, there are some who like the luxurious richness of the current formula and others that find it too rich to use as a day cream … will make a lighter one for them.
Again thanks - has been a great first-time experience so far
