Is the fluorescent whitening agent detection method safe?

Speaking of fluorescent whitening agents, women often use them, but they just don’t know it. What is the detection method for fluorescent whitening agents? Is it safe for human use?

Many women use fluorescent whitening agents, but no one talks about it, and no one knows about it. They use it without knowing what it is. What are fluorescent whitening agents and what are the detection methods? Is it safe for human use?

What is fluorescent brightener

Fluorescent whitening agents generally refer to a class of organic chemicals that can produce blue-violet fluorescence to increase the whiteness visually.

The ability to produce blue-purple fluorescence under ultraviolet light is the basic characteristic of fluorescent whitening agents, but this does not mean that all substances that can produce fluorescence are fluorescent whitening agents or contain fluorescent whitening agents.

Many chemical substances with benzene ring conjugated structures can emit weak fluorescence. They may be active ingredients in certain plant extracts, some polymer resins, sunscreens, fragrances, or even animal or human body fluids.
These objects in our lives also emit fluorescence.

Currently, fluorescent brighteners are mainly used in papermaking, textiles, plastic synthetic materials and washing fields.

Fluorescent whitening agent detection method

sanitary napkin

Sanitary napkins do not need to add fluorescent brighteners during the production process, but why are many sanitary napkins found to contain fluorescent brighteners?

Because it is very likely that the raw materials of sanitary napkins themselves will glow, for example: the adhesive itself will emit fluorescence.

Therefore, it is inaccurate to simply use ultraviolet light to determine whether a sanitary napkin contains fluorescent agents.

Since fluorescence is a physical phenomenon, there is no chemical reaction and it will not have any adverse effects on health.

Therefore, if you think that fluorescence is a problem, you are actually thinking that all substances that can fluoresce are fluorescent brighteners.

When it comes to choosing sanitary napkins, as long as they are not produced by informal small workshops, they basically meet the quality and safety standards, so ladies don't need to worry too much.

Facial mask

For another example, if fluorescent whitening agents are added to a facial mask, then on the surface, the face will appear to be hydrated, fair and smooth after applying the mask, but it will return to its original state immediately after it is stopped.

Generally speaking, if a whitening mask fully complies with the national regulations on cosmetics, it must be used continuously for at least a period of time to be effective. If your skin is noticeably whitened after using one or two pieces, it is possible that fluorescent whitening agents or hormone substances have been added.

The fluorescent agent in some facial masks and sanitary napkins is sometimes brought in by the small piece of plastic film inside. It is the softener in the plastic that has fluorescent properties. The plastic film of the facial mask becomes a "pearl film" to support the mask cloth which becomes soft after absorbing the essence, and the film of the sanitary napkin is used to protect the two tapes.

Is fluorescent brightener safe?

The use of fluorescent whitening agents is allowed in daily chemical products, but there are strict regulations on concentration, dosage, etc.

For example, the fluorescent whitening agent used in Blue Moon Deep Cleansing Laundry Detergent (Bright Whitening) is distyrene biphenyl CBS-X, which is a type of fluorescent whitening agent specified in the industry standard "QB/T2953-2008 Fluorescent Whitening Agents for Detergents" issued by the National Development and Reform Commission on March 12, 2008.

Furthermore, fluorescent whitening agents have been used for more than seventy years, and there have been no cases of illness or personal injury caused by fluorescent whitening agents.

In addition, as long as it is within the appropriate range, the fluorescent whitening agent can enter the stratum corneum of the epidermis. The growth period of the stratum corneum is about 28 days. In theory, the fluorescent whitening agent can be excreted after one month of discontinuation. Fruit acid or physical micro-peeling can also be used to accelerate excretion.

In life, especially for women, it is really unavoidable to use fluorescent whitening agents. Most cosmetics contain them, so they need to be removed regularly.
