Description

Foaming type bicontinuous-phase makeup-removing cleansing liquid

Technical Field

The invention belongs to the field of daily chemicals, and particularly relates to a foaming type bicontinuous phase makeup removing cleansing liquid.

Background

The makeup remover oil has limited removing capability for color makeup containing aqueous film forming agents, such as eyeliner mascara and the like, and only oil-soluble oil can be used for removing oil-based color makeup. The makeup remover can not achieve good makeup removing effect on the oil-based color makeup. In addition, the makeup remover has weaker makeup removing capability, can achieve the effect of removing by rubbing for many times or wiping with a makeup removing towel, and is not friendly to the healthy environment of the skin surface due to excessive rubbing.

The bicontinuous phase is between the vesicular oil and the water-in-oil micelles, with the water and oil in a continuous state, as shown in FIG. 1. In the double-continuous-phase makeup removing product in the current market, the addition amount of the emulsifier is high, the degreasing capability is strong, and the problem of dry skin after washing can be brought to people who dry the skin; although the double-continuous-phase products in the market claim that the water-based color cosmetics and the oil-based color cosmetics can be removed simultaneously and the water and oil can be removed simultaneously, the instant and rapid removal effect cannot be achieved, and the water and oil can be removed only by wiping for a period of time. The foam system consists of an aqueous foam stabilized by an emulsifier. The surface emulsifier layer was adsorbed on the liquid film between the bubbles (right). The polar part (head) of the surfactant is in contact with water, while the hydrophobic chains are directed towards the air, and the emulsifier molecules are also present in the water film, as shown in figure 2. In the traditional oil-in-water system, although foaming can be realized, the polyalcohol and the oil ester play a defoaming role, and the water-in-oil system cannot be foamed. Due to the technical difficulty, the dosage form of the prior bicontinuous phase product is single, and the report of a foam type bicontinuous phase product does not exist. Although the existing market cleansing foam has dense foaming, the foam only can provide skin feeling and texture in use and has no effect on cleaning because of a water-based system.
