Combine sweet almond oil, rosehip seed oil, cocoa butter and emulsifying wax in a heat-proof medium-sized bowl. Place the bowl over a pot of simmering water, and melt the cocoa butter and emulsifying wax. Set aside and cool to slightly above room temperature.
Combine distilled water, hydrosol, aloe, and glycerin into a separate container. While blending in a regular blender or using a stick blender, slowly pour the water mixture into the oil mixture until perfectly emulsified.
Add vitamin E oil, optional essential oils, and preservative, blending again to combine.
Before bottling, make sure that your lotion is completely cooled. Using a funnel and some patience, slowly pour into sterilized bottles and top with a pump. You may find that it is necessary to gently tap the funnel to encourage the lotion into the bottle.
