What is detergent washing powder made from?
« on: 19/07/2016 17:50:02 »
Arthur  asked the Naked Scientists:
   Good day Chris

I am trusting that you are well

I wish to thank you for making me a newborn again. I also wish to thank Mrs Tlhabi for ensuring that South Africans learn something from you.

 Please help me with this question,  what do people use to make detergent washing powder.

I also wish to know how do they make to handy Andy which people use to clean.

I thank you and I will await your reply.

Regards

Arthur Nieklaassen

detergents, mostly...





No, seriously. There are thousands and thousands of types of detergent. Some of them are neutral (like hexadecanol), some are negatively charged (anioninc) like 4-(5-dodecyl)benzenesulfonate, some are positively charged (cationic) like trimethylcetylammonium, and some contain both positive and negative charges (zwitterionic)...

Most domestic detergent powders and liquids are anionic sulfonates, which is why it is a bad idea to mix clothes washed in them with woollens that have been washed in Lux or other soap (cationic natural palmitates and stearates) powders - you get a gritty grey precipitate.  The anionics are very powerful surfactants, usually diluted with a bulking agent (carboxymethylcellulose or water) and viscosity improver (salt!) to reduce toxicity and make dosing easier.

Synthetic cationics are used for several industrial processes such as cleaning oil tanks.

Nonionic chelating agents such as EDTA may be added to soften water and improve the performance of the primary detergent.
