Technical Field

The invention relates to the field of cosmetics, in particular to a glue-free adhesive and glue-free artificial eyelashes containing the glue-free adhesive.

Background

False eyelashes are usually connected to real eyelashes via an adhesive, but during makeup removal, the adhesive is often present on the remaining real eyelashes, thus requiring the use of an adhesive remover to remove these residues. Because the eyelashes are located close to the eyes, the use of an adhesive remover is not easy to handle, and it is also easy for the remover to get into the eyes, causing damage to the eyes.

To avoid this, the hair magnet connecting part is opened to connect the false eyelashes with the upper and lower eyelashes, and the false eyelashes are attached to the real eyelashes using, for example, a magnetic eyeliner. However, a small amount of adhesive is also required in this process, and the adhesive-free magnet connecting portion has insufficient viscosity and is likely to shift or fall off during wearing.

In this regard, the present invention provides a glue-free adhesive in an attempt to solve one or more problems in the art.

Experimental example 1

Samples 1 to 9 were uniformly applied on an artificial eyelash a at the same weight, and then the artificial eyelash a was pressed to another artificial eyelash B, and the resulting eyelash was left for 8 hours on an eye simulator. The artificial eyelashes a were then directly pulled out of the artificial eyelashes B, and the remaining condition of the samples 1 to 8 on the artificial eyelashes B was visually observed.

It was observed that the samples 1 to 6 and 8 did not remain on the artificial eyelashes B, while the samples 7 and 9 had significant residue on the artificial eyelashes B.

Experimental example 2

Samples 1-9 were evenly applied to an artificial eyelash a at the same weight, and then the artificial eyelash a was pressed to another artificial eyelash B, and the resulting eyelash was moved on an eye simulator in a manner simulating opening and closing of the eyelash for 6 hours. During the run, it was found that the artificial eyelashes a bound by the sample 6 were peeled off, and the artificial eyelashes a bound by the sample 8 were misaligned, while the artificial eyelashes a bound by the remaining samples maintained their original positions.

The artificial eyelashes a were then directly pulled out from the artificial eyelashes B, and the remaining condition of the samples 1-5 on the artificial eyelashes B was visually observed. It was observed that samples 1 to 5 did not remain on the artificial eyelashes B, while samples 7 and 9 remained significantly on the artificial eyelashes B.

From the above, it can be seen that the glue-free adhesive of the present invention can secure sufficient adhesiveness to enable the artificial eyelashes to be firmly coupled to the true eyelashes, and can be simply removed in an extraction manner without significant residue, thereby eliminating the need for any adhesive remover. In addition, the glue-free adhesive is composed of components safe to human bodies, and even if a small amount of adhesive is mistakenly inserted into eyes, the adhesive can be removed only by washing with clear water.
