home made star san?

[steve thailand]

star san is
Phosphoric Acid (75%) 50%
Dodecylbenzene Sulfonic Acid (DDBSA) 15%
Isopropyl Alcohol 10%
and some mystery ingredients which i suspect is just marketing

i can't get star san here without a heafty shipping and import duty so i want to build my own. i can find a local supplier for Phosphoric Acid and Isopropyl Alcohol but not DDBSA.

Dodecylbenzene Sulfonic Acid (DDBSA) is a wetting agent, helps break down cell walls i guess, i know nothing about chemistry! i can get this stuff:
Product Name : VR (Wetting Agent for Acid & Alkaline Baths) / วี.อาร์ 902
Other Name : -
Formula : -
Origin : Germany
Characteristics : Liquid, Pale yellow, Mild odor, pH7

do you think that would do in place of DDBSA?

thanks, steve

An easier approach would be to obtain some Peracetic acid as this is what most professional breweries and the dairy industry use for a sanitizer as like Star San theres no need to rinse. Warning though Peracetic acid needs to be diluted before use

thanks for the tip, i found a supplier for that in Thailand. do you think its as effective as a Starsan like system? how long would you soak bottles, FV's etc., in it? there doesn't seem to be that much specific use information around like you get with Starsan.
i did see this about dilution

but not much about soak time

here's a very bad translation of a product i can buy in Bangkok, sounds like it should do the trick.

The guys at the local brewery say it works almost instantly so long as you have cleaned the item first, just dip your utensils into a diluted mix or swill round the insides of barrels etc. Be careful though its nasty stuff when concentrated!!!!!!!

thanks, just ordered some, super cheap from a commercial chemical supply company, now i'm cooking up about 100ltrs/wine a week i need to move away from home brew shops and to commercial supplies.

thx again for the tip
