Description

Non-blushing silicon system eyebrow pencil lead and preparation method thereof

Technical Field

The application relates to the technical field of cosmetics, in particular to a non-whitening silicon system eyebrow pencil lead and a preparation method thereof.

Background

Eyebrow drawing is a decoration technique which makes the female's eyebrows fresh and beautiful, and plays an important role in make-up cosmetics. The products for eyebrow parts on the cosmetic market are various, such as eyebrow pencil, eyebrow powder, eyebrow cream, etc., wherein the most popular product for consumers is eyebrow pencil. The most important reason why the eyebrow pencil products are favored by consumers is that the using method is simple and easy to operate and the eyebrow pencil products are convenient to carry.

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 grease and wax with different melting points, and pouring or extruding the pigment into pencil, usually wood pencil type or mechanical pencil type. In the prior automatic pencil type eyebrow pencil, most of wax base takes hydrogenated vegetable oil as a main body and is compounded with grease with good skin feel and low melting point; for example: an extrusion type eyebrow pencil lead and a preparation method thereof are disclosed in patent application number 202011172041.0, wherein hydrogenated soybean oil is contained in the raw material of the eyebrow pencil lead. The patent application number 202010341578.9 discloses a solid pasty eyebrow pencil, which comprises: hydrogenated soybean oil, hydrogenated palm oil, and hydrogenated castor oil. In patent application No. 201911344541.5, a method for producing an eyebrow pencil lead is disclosed, wherein the composition of the eyebrow pencil lead also comprises hydrogenated palm oil or hydrogenated rapeseed oil.

However, since the wax-based component of the eyebrow pencil lead contains hydrogenated vegetable oil, when the storage environment is improper (for example, the humidity is too high or the temperature is too high or too low), the eyebrow pencil lead is easy to generate blushing and frosting, so that the appearance quality is affected, the make-up effect is also affected, and blushing is an industry problem which is not solved up to the present. Thus, in view of the drawbacks of the current eyebrow pencil leads, the inventor considers that it is necessary to develop an eyebrow pencil lead which is not easy to whiten and bloom.

As can be seen from fig. 3 and 4, in example 4 and example 5, neither blushing nor frosting occurred at 50 ℃ nor 0 ℃. In comparative examples 1 and 2, a relatively pronounced blushing and frosting occurred, and in comparative example 3 the surface layer was substantially entirely covered by the blushing. From the above, it can be stated that the use of silicone waxes and siliconizing colorants and fillers in the present application can jointly improve the blushing problem of the eyebrow pencil lead.

Physical and chemical properties of examples 4 and 5 and comparative examples 1 to 3 were measured, and the results are shown in Table 4.
