Constant temperature & humidity detection of cosmetic brushes

Makeup brushes are beauty tools we often use daily, but their service life is often a concern for you and me. We spend a lot of money on products that we hope will last longer in our lives. Since the handles of cosmetic brushes are usually made of wood and have painted surfaces, the alternation of seasons, the hot weather in Africa, and the cold weather in Russia are severe tests for the quality of cosmetic brushes. Therefore, it is indispensable for cosmetic brush wholesalers or brand owners to require cosmetic brush manufacturers to test the constant temperature and humidity durability of cosmetic brushes before shipment.

1. The effect of high temperature or severe cold on cosmetic brushes

Cold weather can cause cracking of the painted surface of the brush handle, a potential problem that cannot be detected by manual inspection. In addition, if the handle and ferrule are assembled with hot melt glue, cold weather will also cause the brush head to fall off. The hot melt adhesive is fragile under severe cold, and the shock during transportation or drop during use will increase the risk of the brush head falling off.

High-temperature weather or direct sunlight will also increase the risk of the makeup brush head falling off, and the hot melt adhesive will melt under high temperatures. The handle of the same makeup brush will also accelerate the risk of aging or cracking.

2. Put it into the instrument for detection

Put the makeup brush into the temperature humidity chamber, which is a test chamber that simulates long-term exposure to a specific environment for brush handle and glue testing, and select the desired temperature and condition from the digital display. Then hot or cold air (-70℃~+150℃), humid air, or dry air (20~98%R.H.) is introduced into the chamber to meet these conditions. The test chamber can quickly and accurately test the performance of cosmetic brushes under different temperatures and humidity and determine the ability of cosmetic brushes to withstand years of exposure

3. Cosmetic brush UV aging test

The simulated product is placed outdoors for the short or long term. The damage caused by ultraviolet rays in the sun only takes a few days or weeks, and the equipment can reproduce the damage that takes months or years outdoors. See if the product has fading, discoloration, brightness drop, chalking, cracking, blurring, embrittlement, strength loss, and oxidation. At the same time, it can reproduce the damage caused by rain and dew.

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

Many makeup brush buyers usually only pay attention to the product’s price, practicality, or appearance before purchasing. Of course, this is 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

*.Cosmetics brush pull-out testing

*.Temperature And Humidity Test On Handle And Glue

*.Salt Spray Test On Ferrule
