Shaving foam

For making the shaving foam I use:

15g stearic acid,
4g rasped handmade soap which creates a good foam
2g shea butter,
2g cocos butter,
2g borax,
75 g hot water,
4 drops vitamin E
1g rose clay
15 drops of EO Grapefruit and Sweet Orange

This recipe is already tested by my boyfriend and his feedback is very positive. As an improvment I use rasped handmade soap instead of liquid soap and vitamin E. I find this recipe is much better than the recipe in my previous post (Shaving cream For my Son) because PH is neutral: PH=7.
