It is delivered by saponification response between honey bees wax and borax. Borax responds with free unsaturated fats of honey bees wax and structure cleanser which goes about as emulsifier for readiness of cream.
Methodology:
1.Melt the white honey bees wax and fluid paraffin up to 70˚c on a water shower to acquire a liquefied mass.
2.Dissolve the borax in cleansed water and warmth it up to same temperature as that of liquefied mass.
3.Then add this fluid arrangement in softened mass drop by drop with constant mixing.
4.Stir ceaselessly until temperature comes to underneath the 30˚c or it gets cool.
