Bleach

[ksed]

I regularly use bleach to clean dead rock.
I just noticed this on an add for Clorox. It has anti corrosion agents. Would this cause for concern.

Thanks

Googling this brings up a patent issued in 2010/2012 which offers a little information about non-corrosive additives in bleach. Here is a little background from the patent itself:

Sodium hypochlorite solutions are commonly used and highly effective as bleaches and sanitizers for cleaning a variety of surfaces. However, sodium hypochlorite solutions are extremely corrosive to many treated surfaces, in particular, metal surfaces become highly corroded. Hypochlorite solutions corrode surfaces as a result of its composition of sodium hypochlorite, sodium chloride and often sodium hydroxide, each having distinct mechanisms of corrosion. Sodium hypochlorite is a strong oxidant causing metal corrosion through a redox attack. Sodium chloride attacks and penetrates the passivation layer of metals, resulting in pitting of the surface. In addition, sodium hydroxide is corrosive to metals as a result of formation of metal hydroxide

and further down it outlines some of the properties of this specific anticorrosion agent as:

The corrosion inhibitors according to the invention are preferably EPA approved inert material for antimicrobial formulations. In addition, the corrosion inhibitor according to the invention does not adversely impact the stability of the hypochlorite source.

According to an additional embodiment of the invention, the corrosion inhibitor compositions may comprise a hypochlorite source comprising sodium hypochlorite, sodium chloride and sodium hydroxide and about 0.01 to about 2 wt-% corrosion inhibitor comprising a water soluble polyacrylate compound and a water soluble calcium salt, wherein the pH of said composition is at least about 7, wherein the molecular weight of said polyacrylate is less than about 10,000, the ratio of said hypochlorite source to corrosion inhibitor is from about 50:1 to about 200:1 and the ratio of said polyacrylate compound to said calcium salt is from about 6:1 to about 1:6.

The corrosion inhibitor composition according to the invention may further have a ratio of polyacrylate compound to calcium salt from about 4:1 to about 1:4. In addition, the corrosion inhibitor is preferably an EPA approved inert material for antimicrobial formulations and does not adversely impact the stability of the hypochlorite source. According to a further embodiment, the combined hypochlorite and corrosion inhibitor composition has a pH of at least 9.

Now, I'm not comfortable offering an answer to your question mainly because a) this patent was issued to Ecolab and not Clorox so I'm not sure how similar their anticorrosive agents are and b) I'm not sure how you'd define "reef safe" in this context.

Hopefully it helps others.

Bleach is sodium hypochlorite. What is the question - Sodium hypochlorite is an anticorrosion agent (I think). Depending on the official definition of 'anti-corrosion[

The corrosion inhibitors in bleach solutions are often calcium based high molecular weight polyacrylates (carbon, oxygen, nitrogen polymers). I would not think these are harmful.

I'd be more worried about any fragrances they put into the bleach.

Its sodium hydroxide and sodium hypochlorite. Taken from Clorox sds.

The sodium hypochlorite is the "bleach".

The sodium hydroxide is the lye or caustic soda. It's used to raise alkalinity, thus the anti corrosive property.

Should rise out just fine. Air dry socks after rinsing and should be ready to use.

SO seemingly, the answer is 'no' its not a concern (beyond what would be a concern from the bleach itself)

Pretty much.

There also seems to be some Zinc and Aluminum as part of the anti corrosion.

None of the ingredients in regular chlorox bleach concern me:

https://www.thecloroxcompany.com/en...rox-regular-bleach1-concentrated-44600311715/

Water
Water, also sometimes listed on product labels as aqua, is the most widely used of all solvents. It is a colorless, odorless and flavorless liquid and serves as the base of many cleaning products.

Sodium Hypochlorite
Sodium hypochlorite is an essential ingredient in bleach and a variety of cleaning products, serving different functions depending on the concentration level and product formulation. For example, in Clorox's EPA-registered disinfecting and sanitizing products, sodium hypochlorite is the active ingredient that helps to kill certain germs. In laundry and cleaning products it can help clean, remove stains and whiten. In Liquid-Plumr® products, it helps break down tough clogs.

Sodium Chloride
Sodium chloride is also known as table salt and rock salt. It is commonly used in detergents, hand dish soaps, liquid laundry soaps, and fabric softeners to thicken and stabilize formulas.

Sodium Carbonate
Sodium carbonate, also known as washing soda and soda ash, is an alkalinity builder, which is added to laundry detergents to improve cleaning efficiency. It also helps remove alcohol and grease stains from clothing. Builders act like water softeners to remove calcium, magnesium and other ions found in tap water that can interfere with the cleaning process.

Sodium Chlorate
Sodium chlorate is one of the substances that results from the natural breakdown of sodium hypochlorite bleach. It further breaks down into sodium chloride (table salt) and oxygen.

Sodium Hydroxide
Sodium hydroxide, also known as caustic soda or lye, is used as a pH adjuster in cleaning products. As an alkali, it is useful in cleaning products for removing soils that are fatty, oily or acidic.

Sodium Polyacrylate
Sodium polyacrylate is used in laundry detergents to prevent soils from depositing on fabrics during the laundry cycle.

Thanks Randy.
What are your thoughts on the Zinc and Aluminum. The link above show the added minerals.

You mean from the patent?

I don't think they are present in regular chlorox bleach or else the link I posted would/should list them.

Lots of things get patented and not used, or used elsewhere than you think. I have dozens of patents. Only a handful became actual products. Many are patented to prevent competitors from using them and competing with a different product formulation that you are actually selling.

Thanks Randy
Although non of those ingredients mentioned don’t say that they are anti corrosion

The SDS for the Clorox splash less regular bleach didn't show anything as far as anti corrosion agents, other than the caustic soda. I use the Clorox product.

Makes me wonder what is in other makes of regular bleach.

SDS are primarily for safety. Inert and non-toxic or proprietary ingredients can be withheld or omitted. These inhibitors are present at 1:50 or less concentrations.

True, have anyone seen the technical data sheets on Clorox? That should have everything listed.
