Every product that Aesop offers has benefited from the discoveries of agronomists, botanists, chemical scientists and biophysicists. Each of the 2011-2012 science-themed kits is dedicated to a particular theory that captivates Aesop's imagination and has laid the foundations for countless achievements that have followed. Aesop pays homage to the men and many unacknowledged women who have applied themselves to disciplined inquiry. States of Matter contains fine formulations for hand and body plus our portable facial hydrosol. In the fields of chemistry and physics, the expression States of Matter refers to the description of the physical form different phases of matter adopt. Solid, liquid, and gas are the most common states of matter on earth. Plasma, a highly ionised gas occurring at high temperatures, is widely cited as the fourth state of matter.
