BAC 50 Benzalkonium Chloride Concentrated

Applications:

- Disinfectant

- Used as a preservative in cosmetics

- Used in formulations of mils cleaners

- Phase transfer agent

- Microbe corrosion inhibition in the oil industry


Directions of use:

The advised dilution ratio is 1:8 (one-part Bac 50 and eight parts of water). It can be as high as 1:40 application dependant.

Spray and leave formula:

Apply the solution to the affected area and leave it to work. If needed, the advised dilution ratio can be increased.

The product must be used on dry surfaces with no rain forecast for at least 8 hours.

Benzalkonium chloride is readily soluble in ethanol, IPA and acetone. Although dissolution in water is slow, aqueous solutions are easier to handle and are preferred. Solutions should be neutral to slightly alkaline, with colour ranging from colourless to a pale yellow. Solutions foam profusely when shaken.

    SAFE????

    Why was benzalkonium chloride banned in Europe?


    According to the classification provided by companies to ECHA in CLP notifications this substance is fatal if inhaled, is toxic if swallowed, causes severe skin burns and eye damage, is toxic in contact with skin, is very toxic to aquatic life, is very toxic to aquatic life with long lasting effects and causes serious (edited)

    Much like bleach then? All such substances are best not drunk or put in your eyes. Commonsense with all things.

    This might help those wondering about dilution:

    Patio Magic Concentrate (7.5% benzalkonium chloride) recommends the following:

    Destroys mould, algae and lichens on all kinds of hard surfaces including brick paving, patios, glass, perspex, garden furniture, walls, paved areas and driveways. Also suitable for indoor use and as a pre-paint fungicidal wash.

    Apply to dry surfaces only. Always test on a small area before use. For normal infestations, dilute 1 part of product with 4 parts of water. For light infestations, dilute 1 part of product with 9 parts
    of water. Apply 1 litre of diluted product per 3-7m² of surface

    BAC-50 is 50% benzalkonium chloride, so 6.6 times stronger than Patio Magic Concentrate.
    If you follow the Patio Magic Concentrate recommendations, but remember to dilute it 6 times more, you'll be about right.

    What makes this stuff so good is that it's exactly the same as Patio Magic Concentrate (around £20 for 5 litres) but 6-7 times more concentrated. When you buy Patio Magic you're paying mainly for the added water, the additional transport costs, and of course the name.

    In which case patio magic is only around 1.5% BAC for normal use (7.5% diluted 4 to 1 and rounded a bit) meaning BAC-50 is more like 25 times stronger, unless I’ve mathed wrong.

    So use this to soak in and power wash? Or just skip the power wash part?
    Newbold's avatar
    Author
    This will do the job, if left, without the need for power washing. Useful, because power washing will damage many patio surfaces.

    Is run off from this an enduring and serious environmental toxin? Or does it biodegrade harmlessly?

    I find a pressure washer (just water) works perfectly for patio cleaning.

    Environmentally relevant concentrations of BKCs exert potential adverse impacts on aquatic and terrestrial species, including genotoxicity, respiratory toxicity, behavioural effects and neurotoxicity, endocrine disruption and reproductive impairment, phytotoxicity, etc

    Save an extra £3 - I added it to my eBay watch list about 5hrs ago & they’ve just sent me an offer at £26.99

    what's the best dilution ratio for this that everyone is using? (edited)
  9. zillfish's avatar
    Personally would get sodium hypochlorite - 20 litres will be approx £40 and will do the same job on algae, moss etc. Like this, it is extremely toxic so common sense and all that...

    £14.99 from Liquipak eBay, I got this last week.

    This is serious stuff. Don’t confuse this with other patio cleaners.

    Any good for Indian sandstone

    We use it successfully on Indian Sandstone - does an excellent job at a fraction of the price of the branded stuff. Because it’s exactly the same!

    As long as it cleans the moss…that’s all that matters
    AlanGordonPartridge's avatar
    Yes. Can anyone confirm it's effectiveness against moss please?

    Would this remove black lichen from patio slabs and concrete paths?

    Yes.

    Can this be used for conservatory polycarbonate roof? What sort of dilution would people suggest?
    extraj's avatar
    Yes I use it on the conservatory, porcelain tiles, fence and everything else that's got a hint of algae.

    I've always used 1:20

    Personally, I prefer DDAC (Didecyldimethylammonium chloride) over BAC50

    Hi
    If I put this on my drive (block paved), will it kill the weeds between the block paving too?


    Also, is this safe to put on exterior walls to kill algae growth or will it damage the wall?

    Thank you
    extraj's avatar
    No issues putting it on the wall.

    It won't kill weeds very well at all, you need Gallup XL for that (Glyphosate) in a 1:40 mix

    Is this effective for cleaning brick work and stone that has moss and dirt?
