How to Detect and Confirm a Mask Containing a Fluorescent Agent

I’ve been testing various masks this afternoon, and I believe two of them contain fluorescent agents that were intentionally added. Some children’s shoes might also have ingredients that cause fluorescence. But how can we be sure that the fluorescence is not natural or accidental?

The answer isn’t too hard — it just requires a cross-check test. Let me walk you through my process.

First, I used a three-in-one UV analyzer from Shanghai Jiapeng. I had a few known samples to compare with. One of the suspect products had the following ingredients:

1. Water

2. Curacao Aloe Gel

3. Soy extract

4. Witch hazel extract

5. Sodium lactate

6. Panthenol

7. Xanthan gum

8. Tocopherol (Vitamin E)

9. Diimidazolidinyl urea

10. Ureocapsule

11. Flavor

Another mask with similar ingredients didn’t show any fluorescence. Also, when I tested individual components like sodium lactate, panthenol, xanthan gum, and others separately, they didn’t fluoresce.

What’s more, many skincare products contain flavoring agents, but only two of them showed strong fluorescence. This makes me think that the fluorescence in these two masks wasn’t due to their regular ingredients.

I also did an additional test: I placed a small amount of the mask liquid on a filter paper that was free of fluorescence. After drying, the area under UV light showed a bright white spot, indicating a strong fluorescent reaction.

Comparing the fluorescence to copy paper, which also contains whitening agents, I found the color and brightness to be very similar. That further supports the idea that a fluorescent agent was added deliberately.

In conclusion, the fluorescence observed in the mask is most likely due to the intentional addition of a fluorescent whitening agent. This could be used to create a quick "whitening" effect, potentially misleading consumers.

After publishing this post, I received several questions. Some people suggested that even normal ingredients could fluoresce, and that each component should be tested individually for accuracy. Others raised concerns about possible contamination from the filter paper.

To address these points, I retested the raw materials and the base of the mask. The results are shown below.

Charcoal Grill

A charcoal grill is a type of outdoor cooking appliance that uses charcoal as its primary fuel source. It typically consists of a metal frame or cart, a cooking grate, and a charcoal tray or basket. Charcoal grills come in various sizes and styles, from small portable models for camping and tailgating to large, heavy-duty models for backyard cookouts. They are popular for their ability to impart a smoky flavor to food and their versatility in cooking a variety of dishes, from burgers and hot dogs to steaks and vegetables. However, they require more time and effort to set up and maintain than gas grills, and can be more challenging to regulate the temperature.
