This product is a colorless transparent liquid to a white paste, almost odorless and tasteless, and dissolves in water. This oil-soluble azone has been modified to become a highly efficient water-soluble product. It has obvious penetration-assisting effects on lipophilic and hydrophilic active ingredients, allowing the stratum corneum of the skin to interact with lipids and reducing the distribution of effective substances. The phase transition temperature of lipids in the stratum corneum gap increases the fluidity and reduces the diffusion resistance of the active additives in the stratum corneum, so it plays a strong role in promoting penetration. This product is a turbid liquid at room temperature, please heat and shake it well before use. This product is relatively stable to heat and unstable to acid and alkali, and other functional ingredients in the formula may cause its oil and water to separate.
