How does a capsule in a toilet work?

Great.

I’ve been sent a data sheet for Stearyl 25, asking if it is the correct type. Are all Stearyl 25 the same? Should I continue with that or the Stearyl 21??

The data sheet you sent describes the correct material. It doesn’t really matter which one of the two you select - comes down to price really!

Something that hasn’t been mentioned is the process for making the blocks.

It is simply melting the two detergent materials together and then adding the powdered dyestuff and mixing well. The heating should be done over a waterbath - not direct gas or electrical heaters and do NOT make it in the kitchen. The dyestuff is a very powerful colouring agent in very fine powder form. You may be surprised how easily it can distribute itself and stain everything it touches.

Wow, prices are something else!

Thanks for the heads up.

Do you have a recommendation on the amount of each product to use? (more cocamide, more stearyl 21??)

I’ll take note and let you know once I have everything. Thanks

The ratio of the detergents depends on how long you want the block to last sitting in the toilet cistern.

The more CME, the longer it will last but the less effective (less colour released per flush). You may want to start with 10 - 15 % CME and test that first.

Hi all, hope everyone is well.
Was hoping if you could help me answer a few more questions please?

From the items mentioned above, how much foam would they create? I’d like to create maybe 4 inches of thick foam and wanted to ask what could I add to achieve this? There was a previous post about thickening agents and shaving foam, but could anybody advise please?
Also, with these foam bubbles, what could I add to make them last longer, maybe a few hours at least?? But something that is not going to cause any toilet to block?

Hope someone could help with these questions!
Thanks

This is something that you should not do, because it causes problems in wastewater treatment plants, with clouds of foam building up and blowing away in the wind.

Hi Belassi, just read about this, from looking at the photos its a horrible thing to happen!
What about shaving foam, does that cause an issue, just curious as I use that.

Do you know if there is an eco friendly foam that fits my needs with whats been recommended above?

Thanks for bringing that to my attention, unbelievable..

I think shaving foam is really a form of soap, so not really anything new there. So, have you tried making some yet?

Shaving soaps/creams/foams are, as Belassi says, based on soap.

Soap has the characteristic of decomposing before or in wastewater treatment systems and biodegrading - it doesn’t then detrimentally affect ecology.

Your original question was about cistern blocks which I think I answered adequately and in detail after a very protracted series of replies.

The question you are asking now is about a new concept. This being the case, it is or innovation. Nobody here is a charity and new work had to be paid for. If you are happy to pay for development, fine. If not, it is time to either forget the whole thing or start doing some work yourself.

A few points:

1. If you have several inches of persistent foam in the toilet bowl, what then is the point of the cistern block providing colour to the water?

2. “Eco-friendly foams” and “persistent foams” are a contradiction.

3. You mentioned thickening agents. These are for totally different products. Be careful not to conflate completely different product types

Hey John, hope you’re well. You have been very helpful in recent posts and I’ve enjoyed your guidance. Apologies for the lengthly understanding process, your patience is much appreciated!
Nonetheless, I’ve been reading from the guidance you’ve given me, and searching for the answers to my last post, but haven’t had much luck, so thought I would ask here.
If these questions are no longer open to advice, then please drop me a pm so I can continue with this experiment. Would be great to speak a more fluid conversation.
Otherwise would love to have some help.

Ryoo,

It’s not so much a case of not being open to advice, I think you are venturing beyond your capabilities, especially as your original enquiry was a pretty general one asking how in cistern toilet blocks worked. This developed into the ingredients of the blocks and finally to my seeking out suppliers of suitable products with availability in small quantities for the offered formulations.

Your current query is not for advice, it is asking for development information for new ideas. This takes time and money on our part and it is a bit much asking for this on a general forum.

If you do wish to pay for work to be done, there is a section at the top of the home page of people offering development services, although the negatives mentioned in my previous reply still hold true.
