Description

  The present invention does not contain a surfactant generally used as an emulsifier in a cleansing agent, and has an excellent emulsification stability over time, safety for eyes and skin, makeup-removing effect, and a moist feeling after use. The present invention relates to an activator-free oil-in-water emulsion cleansing agent composition and a sheet-like cleansing formed by impregnating a sheet base material with this composition.

  Makeup cosmetics are required to be resistant to makeup collapse, and an oily base or a film-forming agent is used to prevent makeup collapse. Sunscreens have come to be used on a daily basis in order to prevent the adverse effects of ultraviolet rays, but oil bases are often used to improve water resistance.

However, if the makeup effect is increased or the water resistance is increased, there is a problem that it cannot be efficiently removed with a normal aqueous makeup remover, and a formulation with an excellent makeup remover effect has been developed.
For example, technology development using an oil component, surfactant and amphiphilic oil (Patent Document 1), technology development using a specific surfactant, oil component, polyhydric alcohol and water (Patent Document 2, 3 and 4), but all the techniques are used to enhance the makeup-removing effect of the surfactant.
However, non-ionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants that have been used as cleansing ingredients are not only safe for the skin, but are also used as makeup removers around the eyes. Since it is often used, it is a well-known fact that it is preferable not to use it as much as possible from the viewpoint of safety for eyes.

In view of these circumstances, cleansing agents that do not use surfactants have been developed.
For example, a sheet-type cleansing agent using an oil-in-water emulsion formulation in which a low-boiling oil component is emulsified with a water-soluble thickener has been disclosed (Patent Document 5), but it must be separated at a high temperature. In addition, there is a poor impression as cosmetics due to separation and non-uniformity of the makeup removal effect, and there is little moist feeling of the skin after makeup removal, and there are disadvantages as the commercial value of cosmetics.

Was added to the diluted aqueous liquid phase and homogeneously mixed to obtain a surfactant-free oil-in-water cleansing composition. The obtained cleansing composition was evaluated by the method described above. A commercially available oily mascara was used as the cleansing product.

  All of the cleansing compositions of Reference Example 2 and Examples 4 to 6 in Table 2 formed a good oil-in-water emulsion composition and had good long-term stability. Moreover, in Examples 4-6, it was confirmed in sensory evaluation that it can be suitably used as a cleansing agent excellent in cleansing effect and excellent in moist feeling after use.

Sheet cleansing The oil-in-water emulsified cleansing composition of Example 5 shown in Table 2 was impregnated with a nonwoven fabric of 60 g / m ² of 100% cotton by impregnating the nonwoven fabric with a weight ratio of 3 times to give a sheet cleansing. Obtained. The obtained sheet-like cleansing was evaluated by the method described above. A commercially available oily sunscreen was used as the cleansing product.

As shown in Table 3, the sheet-like cleansing of Example 7 formed a good oil-in-water emulsion composition and had good long-term stability. In addition, Example 7 was confirmed by sensory evaluation that it can be suitably used as a sheet-like cleansing that has an excellent cleansing effect and an excellent moist feeling after use.
