Description

Cosmetic composition
Technical Field
The invention relates to a cosmetic composition, a preparation method and application thereof.
Background
Mascara is an important part of daily make-up. Mascara can be classified into washable and anhydrous dosage forms. In terms of safety, the washable type mascara can replace volatile solvents in anhydrous dosage forms with water, so that the irritation of mascara is greatly reduced, and the safety is improved. In the aspect of anti-halation, the anhydrous dosage form generally needs to be added with high proportion of solid grease, so that halation is easy to generate, and the film forming agent in the washable type can form a hydrophobic and oleophobic solid film, so that halation is improved. In terms of easy removability, the water-washable formulation can be easily removed with warm water, eliminating the need for the use of oil-soluble make-up removers for anhydrous formulations. Therefore, the water washable type clothes are popular with consumers.
In order to ensure high consistency of eyelashes, more film forming agent or wax needs to be added into the washable mascara, which can lead to poor curling degree of the brush-coated eyelashes, meanwhile, adhesion is easy to occur between the eyelashes in the brushing process, and particularly, visible caking phenomenon, commonly known as 'fly legs', is caused at the tips of the eyelashes. Therefore, it is desirable to develop a washable mascara that not only provides good curl of eyelashes, but also does not cause clumping of the eyelashes.
US9072686B2 discloses a mascara composition comprising at least one polyurethane composition and at least one hard wax, wherein the hard wax content is at least 12% by weight or more, providing a brush comfort, an improved thickening and curling.
CN 104994837A discloses a composition comprising a latex film former comprising a wax dispersion and a thermoreversible gel polymer.
CN101039719a discloses an emulsion mascara containing an imide polymer with film-forming properties, wax, water and pigment or colorant.
