Our Silver Sparkle is a gorgeous reflective silver mica that adds an amazing sparkle to bath bombs and soap. This is larger sized particles so almost resembles glitter. We recommend using polysorbate 80 if using in bath bombs. We use 1tsp per 1kg of baking soda. Effects may vary it seems depending on light in bathroom. Our bathroom has a lot of light so shimmer is easily seen.
Usage rate for soap: 1 tsp per pound of oils. Use less for a lighter colour, use more for a darker colour.
Cosmetic grade - safe for use on face, eyes, lips, skin.
