Makeup Brush Tensile Test

1. Types of bristles of makeup brushes

The bristles of makeup brushes are generally divided into animal hair and synthetic fibers. Natural animal hair has complete scales, so the hair is soft and fluffy, the color is even and docile when saturated with powder, and it does not irritate human skin. Synthetic Fibers are harder than animal hair and are suitable for thick cream or liquid cosmetics.

2. Tensile test of synthetic fibers

Due to the different production processes and materials of synthetic fibers, the tensile strength of the bristles produced is also different. The lower tensile strength of the bristles will result in lower-quality makeup brushes. It is the best way to detect the tensile strength of The bristles with a bristle strength detection device. The camera records the values on several tensile gauges. When each bristle is stretched to break, the camera records the video to leave the detection data for later comparison.

3. Pull test of bristles

The tensile test of synthetic fibers is for a single or a certain number of synthetic fibers. Just test the tensile strength of synthetic fibers to ensure that the synthetic fibers used are of high quality and meet production requirements.
The bristle pull test is a tensile test for all synthetic fibers on the brush head. The trial aims to ensure that the bond between the bristles and the ferrule is secure. Testing the mechanical strength of this connection was critical to ensure the bristles would withstand prolonged use without falling out or deforming.

4. Pull test of the handle

The pull test of the handle is a tensile test on the connection between the handle and the ferrule. It is mainly to ensure that the link between the handle and the ferrule is firm and will not fall off or deform the brush head due to daily use .
Tensile testing is the most common method for checking the mechanical strength of cosmetic brushes. The cosmetic brushes under test are clamped between two tension grips, and a load is applied at a constant rate by a tension tester equipped with a load cell. It pulls the Makeup brush into a straight line to measure its performance of the makeup brush. There should be less than 2.5 lbs of pull between bristles and ferrule and less than 3.0 lbs of force between ferrule and handle.

5. What are the necessary tests in OEM or ODM makeup brushes?

Many buyers of makeup brushes usually only pay attention to the price, practicality, or appearance of the product before purchasing. Of course, this is one of the rights and interests of each buyer and one of the means to expand their brand, but they often ignore many necessary test items. As a result, the quality of the makeup brushes they purchased could have been better.
To this end, we have compiled some necessary testing items for your reference:
*.Acid-base test
*.Drop test
*. Vibration test of product packaging
*.UV Weathering Test
*.Temperature And Humidity Test On Handle And Glue
*.Salt Spray Test On Ferrule
