Description

Refill for eye-line and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to an eye-line pen refill and a preparation method thereof.

Background

The eyeliner is a kind of colour cosmetics, and the eyeliner is a long and thin line drawn by eyeliner at the bottom of upper and lower eyelashes, and the eyeliner or eyeliner powder drawn by friction can be naturally and uniformly filled in the pores between eyeliner hairs to emphasize the outline of eyes, raise stereoscopic visual effect and raise aesthetic feeling. However, the oil and fat secreted from the skin or the liquid secreted from the lacrimal gland interact with the ointment of the eyeliner, and after long-term makeup, the eyeliner has the defect of poor adhesion, and particularly, the eyeliner with weak water and oil resistance is easy to remove makeup, faint and stain and the like, thereby affecting the aesthetic feeling. Therefore, the requirement of the eyeliner refill on the ductility, uniformity, durability and product hardness of smearing is certain.

Chinese patent CN109431923A discloses a durable non-fading eyeliner refill and a preparation method thereof, which adopts three film forming agents consisting of three compounds, namely three composite film forming agents of trimethylsiloxy acid ester/dimethiconol cross-linked copolymer/isododecane, trimethylsiloxysilicate/polypropylsilsesquioxane/isododecane, trimethylsiloxysilicate/cyclopentadecyldimethylsiloxane which are added in the specification [0005], and has excellent film forming property, durability, softness and waterproofness. However, the film forming agent added into the eyeliner refill is complex in component and large in addition amount, is not easy to remove makeup, and has large damage to skin around eyes.
