Ulta toothpaste whitening products are often marketed as having a “natural” whitening effect, a term that refers to a product’s ability to whiten teeth, and these products are popular among dentists, who often recommend them as a “health-enhancing” treatment.
However, a new study from the University of California, Berkeley found that whitening and whitenings actually contain some ingredients that are toxic to the human body.
The study was published in the journal Environmental Health Perspectives.
“The toothpaste-containing whitening product marketed by Ulta and others as having ‘natural’ whitening properties actually contains a wide variety of toxic chemicals that are not approved by the Food and Drug Administration for use in dentistry,” said lead author Dr. Michael A. Stumpf, a professor of dentistry at UC Berkeley.
Stumpf and his colleagues examined ingredients in whitening formulas from two companies.
The whitening formula contained two ingredients that were deemed by the FDA to be potentially toxic: methylparaben (also known as DEHP), which is used in many products to retard growth of mold, and dibutyl phthalate (also called PVC), a compound that has been linked to developmental problems in humans.
The ingredients in the whitening whitening toner were labeled as containing only “toxic” amounts of these two ingredients.
“These ingredients are found in so many toothpaste products, toothpastes, and other products, and have been shown to cause harm to our bodies, particularly to infants,” said Stumpff.
“Toxic ingredients are often used in whiteners and whiteners are typically added to whitening solutions in order to keep the toothpaste soft and to make it easier for the toothbrush to reach the teeth,” he said.
Stampf said that the amount of toxic ingredients in a toothpaste product should be judged on its ingredient list, not its chemical composition.
“It is not uncommon to see toothpasta with toxic ingredients, including the aforementioned chemical ingredients, found in toothpastas sold as whitening tablets,” he explained.
“Toxic substances should not be listed in toothpaste ingredients lists.”
The study did not investigate the efficacy of the products marketed by the companies that made the toothpastans.
However it did look at the results of a different study that looked at the efficacy and safety of toothpastan whitening.
The researchers examined results from a study conducted by Dr. Robert A. Murgatroyd, who was a professor at the University at Buffalo School of Dentistry and a professor in the Department of Oral Biology at the time.
The researchers analyzed data from a survey of about 6,000 adults that was conducted between 2008 and 2010.
The survey asked participants about the amount and types of whitening treatments they had used, how often they had tried the products, the ingredients they used, and how long they had been using them.
The results showed that white toothpastons and whitener products sold in the U.S. are commonly used to whitened teeth and to whiteners.
The results of the study showed that, of the 1,000 respondents, only 16 percent of them reported that the whitener and toothpaste were effective at whitening their teeth.
In addition, less than one in four whiteners were effective in preventing tooth decay, compared to more than one-quarter of whiteners in toothbrushes.
Dr. Mungatroye concluded that whiteners sold in this country have a lower efficacy rate than toothpaste.
“We were concerned about the high levels of toxicity found in whitener ingredients and the lack of efficacy of whitener treatments, but this study did show that whitener formulas do have potential for toxic ingredients that may contribute to tooth decay,” he told Newsweek.
“Therefore, these whitening formulations should be avoided by consumers.”
A spokesperson for Ulta told Newsweek that Ulta does not sell toothpastors, whiteners, or whitening kits.
“Ulta is committed to supporting and encouraging safe and effective health practices,” said the spokesperson.
“Our product line is designed for the convenience and wellness of our customers, who want a product that is as effective as possible for a variety of health conditions,” said a spokesperson for the brand, which has an annual sales of $1.5 billion.
