Is methylparaben safe?

The hated paraben

Cosmetics that do not contain preservatives are very popular.

One of the most hated preservatives is paraben, which is why there are so many cosmetics that advertise themselves as "paraben-free."

However, in reality, not many people clearly understand why parabens are disliked.
Also, there are multiple types of parabens, and not all of them pose the same risks.

In this article, we will take a closer look at methylparaben, the most commonly used ingredient in cosmetics.

Methylparaben is absorbed through the skin.

As mentioned at the beginning, there are several types of parabens.

• Propylparaben
• Isopropylparaben
• Butylparaben
• Methylparaben
• Ethylparaben

Methylparaben is just one of many parabens, and tends to be used together with other parabens and preservatives in cosmetics.

Cosmetics used around water or in contact with the skin are products that are prone to mold and bacteria growth even with normal use. That's why parabens are used to prevent the growth of germs.

Using spoiled cosmetics can lead to serious health problems such as blindness, so maintaining an appropriate preservative effect is essential for safe cosmetics.

By the way, methylparaben is known to be absorbed through the skin , especially when the skin is damaged.

Parabens are then absorbed through the skin and into the bloodstream.

Does methylparaben accumulate in the skin?

Methylparaben is absorbed through the skin, but does not remain in the body for long.

There have also been studies in dogs, young children and adult men showing complete excretion in the urine within 48 hours.

It is also known to decompose when released into the air or exposed to sunlight for extended periods of time.

Is methylparaben carcinogenic?

Research into the safety of methylparaben and other parabens is being conducted worldwide.

However, there is still no conclusive evidence to support the various concerns, which is why no country has banned the use of methylparaben.

"Methylparaben is carcinogenic"

Has anyone heard such a rumor?

However, there are still many unknowns and little objective evidence to prove that this is true.

This is because the American EWG , which evaluates the safety of cosmetic ingredients, has not indicated any carcinogenic risk (although it does say there is a risk of allergies and endocrine disrupting effects ).

In addition, a study conducted by the Centers for Disease Control (CDC) in the United States in 2005 tested the urine of 2,548 subjects and found that methylparaben was detected in 99% of the participants' urine, but no association with any health problems was found.

Link to breast cancer

Rumors of parabens' carcinogenicity first emerged after a 2004 study found traces of parabens in 20 breast cancer tumor samples.

Of the parabens detected, methylparaben was found in the highest concentration, accounting for 62% of the total.

However, this study only found that parabens were present in breast tumors, and did not determine that methylparaben is carcinogenic.

So there's not enough evidence to conclude that parabens are the cause of cancer.

However, it is said that the danger of methylparaben only increases when ingested in large quantities. In animal experiments, the following symptoms were observed when ingested in extremely high concentrations.

• Weight loss
• Stomach injury
• Miscarriage or birth defects
• Damage to sperm, testicles, and uterus
• tumor

However, the amount of methylparaben used in animal testing is not likely to be used in general cosmetics, so it seems safe to say that these risks are almost nonexistent with the amount of methylparaben used in cosmetics.

Possibility of allergic reaction to methylparaben

Allergies to parabens are not common .

Also, if an allergy does occur, it is usually a delayed contact allergy, meaning the symptoms do not appear immediately after application to the skin, but after some time has passed.

Symptoms rarely occur immediately after application, but some studies have shown that this can sometimes happen.

Symptoms of a skin allergy caused by methylparaben include:

• itch
• Bumps and blisters
• Dry, scaly skin
• swelling
• Skin feels hot
• Redness and swelling of the eyelids (if the condition occurs near the eyelids)

No life-threatening allergic reactions such as anaphylaxis have been reported.
