Thickening agent for Sodium Hypochlorite

How about starch?

How about trying a thick domestic bleach such as that used as a toilet cleaner. I think that is thickened with sodium chloride

Won't the bleach destroy or weaken the fabric?

So long you do not allow stain it for too long, you could create wonderful pictures by weaken the dye in the fabric.

Hi All,

Thank for the contribution, Sodium Hypochlorite will attack anything organic. Therefore any thickening agent will have to be inorganic and fine enough to turn Sodium Hypochlorite to silkscreen paste. Plse keep the contribution coming, thank you.

You might try gelatin or plain Jello.

Instead of thickening the bleach, pehaps you could use a sponge/foam in your press to control the amount of bleach delivered. If this is an automatic press it might be difficult though. Anyway, just a thought!

Cab-O-Sil preciptiated silica. Inorganic, relatively inert and should thicken the bleach with minimal stirring. Gets used quite a bit to gel all sorts of things from paint and adhesives to screen inks etc.

There is formulation that we develop in our labarotuaries for our customer, that may help you.

6 part sodiumlaurylether sulphate %70 2 EO

1 part mrystyl aminoxide

25 part hypochloride

water to make up 100

increasing sodiumlaurylether suphate and mrystyl aminoxide also increase the final viscocity together with the NaOH %48 you add it

NaoH to find out the viscosity you need (around 0,5 to 2 % depending the quality of the hypo)

Anything to ask is well come

there are some of my customer are using this formula for almost same aplication.

Thank a million and shall try this formulation!

You very well come, please let me know the result with its plus and minus so we can modify it in our labs. I think you also need a masking material for the sharp edges of your figures to prevent the diffusion of hypo on the fabric. like one negative, one possitive, That mask material should be removable by washing.

The only things which increases when you share are the knowladge

Dear Sir.

Can same formulation be used in making commercial thick bleach and which company manufactures the thickeners

Hi,

I am wondering that, did you try that formulation. What was the result. If anything missing we can help you futher.

Hi Hasan,

Never did get to try as I was not able to get to purchase one of the chemical which require a permit here! So managed to purchase an off the shelf products from a super mart and anyway it did not work as well as I have thought. Thank for the contribution.

Best regards,

Mike

I do not know which chemical is it that you need permission. but you can try domestos type thicked type of hypochlorite for cleaning purposes. You can add a little sodium hydroxide in to give more viscosity. Too much sodium hydroxide makes you loose viscosity.

Hope this can help.

I would cut the pattern in plastic and just spray the material lightly with the peroxide bleach, then after proper time submerge in a 50/50 water/vinegar bath to neutralize the bleach...

Wallpaper paste?

The forum would appreciate a list of what has been tried already so as to eliminate fruitless guesswork.
