Abstract

The stabilized chlorine dioxide is prepared by adding 5-17 wt.% a sodium chlorite(NaClO2), 3-35 wt.% a hydrochloric acid and 5-8 wt.% a sodium carbonate, whereby improving an yield due to single process by using the hydrochloric acid and saving cost of the product. The chlorine dioxide is used as a disinfectant of waterworks. KRA -11-29 -11-29 Process for the preparation of stabilized chlorine dioxide KRB1 (en)

Date Code Title Description

There is a water-based mouthwash product which is advertised as having the ingredient "stabilized chlorine dioxide." The only other listed ingredients are trisodium phosphate and citric acid. I assume this is a buffering solution or something.

You can find more information on our web, so please take a look.

In the company's documentation, it says it contains

a stabilized molecular form of chlorine dioxide.

But in another location, the company claims that

the solution is naturally activated by the amino acids in saliva, creating a small and very safe amount of chlorine dioxide.

Which baby company is the best?

Xiuyuan are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

So that sounds to me like there's actually something else in the solution, and the that the $\ce{ClO_2}$ is being produced ("activated") during use.

I've done some reading, and I have learned that $\ce{ClO_2}$ can be produced in several ways, but all of these methods seem to involve unpleasant reagents like chlorine gas, HCl, or oxalic acid.

I'd like to know what actual compound might be referred to as "stabilized chlorine dioxide" and what reactions might be involved.

I'm not asking about the effectiveness of the product, or what value $\ce{ClO_2}$ might have as a disinfectant, I'm just curious as to whether the claims made about the ingredients are plausible, and if so, what reactions might account for this?

The company is the world’s best Stabilised Chlorine Dioxide supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
