Is there a risk of red and black henna being contaminated with lead and PPD?
“Medium adult Uses Nine personal care products every day, with 126 unique chemical ingredients.” We used to think that anything put on the skin would “always stay on the surface of the body,” and the only thing you had to worry about were issues like localized skin irritation. But, over the decades The latter, “it has been recognized that some topically applied substances can penetrate or pass through human skin” and end up all over our bodies.
Take the toxic heavy metal lead (Pb), for example. As you can see in the chart below and at 0:38 in my video Is henna safe?to see if it can be lead Absorbs Through the skin to the body, the researchers applied lead to a person’s left arm and then measured the level of lead in the sweat exiting their right arm over the next few days. They note a significant rise, proving for nearly 30 years that “lead can be absorbed through the skin and rapidly distributed throughout the body.”
This has led public health authorities to “recommend this to parents.” to avoid Using cosmetics on their children that could be contaminated with lead.” What cosmetics might it be? Since it is a natural component of many color pigments, lead is found in a wide variety of cosmetics – from eyeliner and lip gloss to hair cream and paint nails, as you can see below and at 1:07 in video. Owned by the Food and Drug Administration Designation An upper limit for lead at 20ppm. Although only some samples of henna exceeded this upper limit, because henna “is used to treat hair, as an alternative to chemical hair dyes and also for temporary tattoos, such amounts of lead that remain on the skin or hair for a long time cannot be safe.” In fact, studies show that lead “may not have an identifiable safe exposure level, even with the lowest levels shown to affect the fetus and the central nervous system in children.” Thus, the use of henna, especially among children, may be form danger to public health.” Therefore, “increasing awareness of the dangerous toxic effects of henna appears to be the only reliable way to end or at least reduce the use of such hazardous substances especially when children are involved.”
Traditionally, henna was just the dried leaves of the plant. Recently, other ingredients have been added to impart a stronger color, such as lead, He said To be “one of the most common and scandalous additions to henna.” But lead is not as common as paraphenylenediamine (PPD), which is derived from coal tar.
“Traditionally red paste used, known as ‘red henna’, rarely produces adverse effects, but to achieve a darker dye, known as ‘black henna’, several additives can be used, including ‘animal urine’. Pee better than PPD, though, so “coal tar hair dye” can Wave Bad skin reactions, such as blistering and scarring. Why add PPD at all? In addition to achieving a darker, longer-lasting color, PPD helps fall short The duration of the tattoo process is 12 hours to less than 2 hours. Therefore, while using black henna may be “tempting”, it does have the potential for short- and long-term side effects.
How common are these reactions? best estimate he is About 2.5 percent, which means that 1 in 40 children who get a black henna tattoo may have an allergic reaction. Unfortunately, this practice has become “fashionable, ever since the Spice Girls adorn themselves with these body designs.” (Thanks so much, Spice Girls!) There is no such thing as natural Black henna, so it’d probably be better respect The traditional practice of red henna, lest temporary tattoos turn into a permanent scar.”
The problem is that “PPD can be so have found It’s in products labeled “red henna” too, so just because it’s red doesn’t mean it’s not risky. This is bad news for the $100 million industry.
Since henna of all colors is often adulterated, according to FDA guidelines, “henna should not be applied to the skin at all.”
