THERMOCHROMIC CONTAINER FOR DEPILATORY COMPOSITIONS

摘要

The invention relates to a container for depilatory compositions, which is made from a plastic material and is characterised in that its composition includes at least one thermochromic material containing two or more reversible thermochromic compositions, the first in a concentration of 0.1-8% and the second in a concentration of 0.05-8% by weight of the thermochromic material, both being heat-sensitive at a temperature above 40 °C but at different temperatures from one another, such that the first is heat-sensitive in a lower temperature range than the second. Owing to the thermochromic properties of the container of the invention, the container is able to change colour according to the temperature applied to it, once heated, indicating the suitable moment of use and the moment for non-use.
