Cosmetics Particle Size
Project Description
Cosmetics Physical Chemistry Laboratory needed to verify labeling claims for the ingredients and particle size of 2 water based products claims to have nano-sized the ingredients.
Product #1 -
Ingredients are: Helicoll Collagen, Elastin, Methylsulfonylmethane (organic sulfur), Silver, and Hyaluronic Acid.
Particle size is listed at an average of 1.175 d.nm with a standard deviation of 0.2002.
Product #2 -
Ingredient is: Hydrated Clinoptilolite Zeolite
Particle Size: no documentation provided, but claimed to be <10 nanometers
I would like to verify that the ingredient list and particle size is accurate.
