Description

Silicon-system eyebrow pencil lead without whitening and preparation method thereof

Technical Field

The application relates to the technical field of cosmetics, in particular to a silicon system eyebrow pencil lead without whitening and a preparation method thereof.

Background

Eyebrow penciling is a decoration technique, which makes women's eyebrows beautiful and glowing, and plays an important role in makeup cosmetics. The products for eyebrow parts in the cosmetic market are various in types, such as eyebrow pencils, eyebrow powder, eyebrow cream and the like, wherein the product most popular with consumers is the eyebrow pencils. The primary reasons why eyebrow pencil products are preferred by consumers are the simplicity and ease of use and portability.

The main components of the eyebrow pencil lead are vegetable wax, beeswax, pigment and the like. The eyebrow pencil lead is made up by dispersing pigment in oil and wax with different melting points and making it into pencil by pouring or extruding, and is usually a wooden pencil or propelling pencil type eyebrow pencil. The wax base in the eyebrow pencil mainly takes hydrogenated vegetable oil as a main body and is compounded with low-melting-point grease with good skin feel; for example: the invention discloses an extrusion type eyebrow pencil lead and a preparation method thereof in patent application number 202011172041.0, wherein the eyebrow pencil lead comprises hydrogenated soybean oil as a raw material. In patent application No. 202010341578.9, a solid pasty eyebrow pencil is disclosed, which comprises: hydrogenated soybean oil, hydrogenated palm oil, and hydrogenated castor oil. The patent application number 201911344541.5 discloses a preparation method of an eyebrow pencil lead, and the eyebrow pencil lead also comprises hydrogenated palm oil or hydrogenated rapeseed oil.

However, as the wax-based component of the eyebrow pencil lead contains hydrogenated vegetable oil, when the storage environment is not proper (such as too high humidity or too high or too low temperature), the eyebrow pencil lead is easy to whiten and frost, which not only affects the appearance quality, but also affects the make-up effect, and the whitening is an unsolved industrial problem. Therefore, in order to overcome the defects of the conventional eyebrow pencil lead, the inventor considers that the eyebrow pencil lead which is not easy to whiten and frost is needed to be developed.

Disclosure of Invention

In order to solve the problem that the refill of the eyebrow pencil is easy to whiten and bloom, the application provides a refill of a silicon eyebrow pencil without whitening and a preparation method thereof.
