Are all single phase homogeneous transparent liquids. With the continuous pursuit of consumers for the appearance and individualization of volatile liquid, a few air freshener companies have developed two-phase volatile liquid with double-layer appearance, but the two-phase volatile speeds are extremely inconsistent, that is, when the product is not unsealed, the appearance of the liquid is an even double-layer structure, and when the product is used in an unsealed state and gradually volatilizes, the double-layer structure is gradually destroyed to become single-phase volatile liquid. Therefore, there is a need to develop a volatile liquid formulation that can maintain a bilayer structure and volatilize at a constant rate during use.
