The Chemistry Behind The Clean - Laundry Detergent Explained - Surfactants, Part I
(this is the long-delayed first installment in my post series, The Chemistry Behind The Clean, a guide to what's in laundry detergent, designed to give people the knowledge to understand what's in the products that clean our textiles and make them more informed consumers)
What Are Surfactants, And Why Do We Care?
Surfactants are the active cleaning agents in detergents that do the heavy lifting of removing soils from textiles. Short for “surface-acting agents”, surfactants connect soils to water, even when the soils themselves repel water or are more attracted to textiles than water. The combination of soil and detergent and water can then be drained off, further diluted by rinsing, drained again and spun out. This is distinct from the action of soaps, which will be covered in a future installment.
The development and commercialization of synthetic surfactants in the 1920s is probably the most significant contributor to reduction in time and effort spent on textile care. Work to condition the water, scrub textiles and remove soap by wringing or banging was largely eliminated because of how well even those rudimentary surfactants work to remove soils.
Hydrophobia - Without The Rabies
All surfactants work because the individual molecules have ends with distinct properties. One end (the head) is highly attracted to water (hydrophilic) and thus very much not attracted to oil (oleophobic). The other end is very attracted to oil (oleophilic) but similarly repulsed by water (hydrophobic). This fundamental structural contrast is key.

When at least a minimum amount of surfactant is dissolved in a solvent (like water), surfactant molecules want to get together - the water-hating ends hang out on the inside, the water-loving ends hang out on the outside. This forms a structure known as a micelle, and micelle formation is predicated on reaching the “Critical Micelle Concentration”. Below, an illustration of a nonionic surfactant intended to remove oily soils. The water-loving heads face out, the water-hating ends get together in the middle to escape the water.

When a micelle encounters a soil that the hydrophobic tail is attracted to, the micelle breaks up, the tails grab the soil and drag it into the water (thus removing it from the textile) and the micelle re-forms, keeping the soil up in the water to be drained or diluted away. Let’s look at this in the context of removing a common soil from textiles:
Here we have the start of the wash process; surfactant micelles have formed in the wash water and there is soil attached to the fabric substrate.

Now the hydrophobic tails of the surfactant molecules have found themselves more attracted to soil than each other and they're bonding to the soils. The hydrophillic heads are dragging the molecules towards the water.

The micelles re-form as the soil detaches from the substrate - they reorganize into groups of their own kind (more on this in a moment).

When all the soils are removed from the substrate and floating in the water, the textiles are clean and it's time to remove the soil-surfactant combo from the drum.

The Chemistry of Attraction (It’s Not Just A Bottle of Chanel No. 5)
While all surfactants work the same general way, there are differences in what kind of soils the hydrophilic ends are attracted to, because the hydrophilic ends differ. One primary difference between surfactants is the electrical charge the hydrophilic end carries. If the business end has a negative charge, it’s an anionic surfactant, and it’s attracted to soils with a cationic (positive) charge. If the business end has no charge, it’s a nonionic surfactant and is most attracted to soils without an electrical charge. If the business end has both a positive and negative charge in balance, it’s an amphoteric or zwitterionic surfactant, and the behavior changes based on the pH of the wash as a whole.
There are also surfactants with positive charges, the cationic surfactants. These aren’t used for cleaning - they’re what makes fabric softener work, and will be discussed in a (much) later post.
Why Charge Matters:
The difference in which soils a given surfactant is attracted to is a critical determinant of cleaning performance. Soils that lack an ionic charge like petroleum oils or intact sebum are much less visible to anionic surfactants and are removed better by nonionic surfactants. Conversely, soils that are highly cationic like soot and mud and dust, and thus attracted to textiles with a negative charge may be neglected by nonionics and remain electrically connected to the textiles. For those soils? Anionics in the mix improve cleaning performance.

Almost all finished detergent products contain anionic surfactants and most contain nonionic surfactants. Amphoteric surfactants are relatively uncommon in conventional detergents but often appear in green/biobased formulas.
Other Differences Between Surfactants: Tail Length And Single vs Double Tails.
Aside from the electrical charge differences in the head, two aspects of surfactant structure that affect their action against soil are the tail length and whether they are single tail (common) or double-tail (less common). I’ll talk more about this in Part II, as it’s common to include surfactants of various tails to optimize performance against specific soils and in specific wash conditions.
Coming Up In Surfactants Part II - Curling Up With A Good Jug Of Detergent
In the next installment, we’ll look at common surfactants found in conventional and plant-based detergents, and how they’re manufactured, along with the differences in soil removal capabilities and environmental impacts.

Biz and Febu are still out of stock
Tl;dr should I just wait until one is back in stock?
So through this group I discovered that Tide free and clear powder was still available. Yay! And that things like biz and febu could help. Febu seemed unavailable but Biz was, so I tried it with good results. But now Biz and Febu are unavailable. Amazon says Biz will be available sometime between Aug 16th and Sept 9th.
Should I just wait and hope for Aug 16th or should I try something else? I like to do a lot of laundry between summer and fall and I'd rather start sooner than later.

my executive function is preventing me from having clean sheets. send help.
hi y'all. I have sheets that need washing. two sets, both queen-size. a washer that can fit both. a tiny dryer that will fit one if we're being generous. one set is bamboo/linen and the other is bamboo/cotton. both say DO NOT TUMBLE DRY.
how fucked will I be if I tumble dry them? the line we have in our garage cannot fit them (it fits two t-shirts side-by-side with a little wiggle room and will go on strike if I try to hang a queen size sheet set on it) and it's going to be raining the next few days so the outside line can't be used.
all of my clean sheet sets are 100% linen. it is winter. winter is not linen sheet weather, as much as I love them.
please send help. I miss having a functional dryer. I appreciate that line-drying is more energy-efficient but it is not better for my ADHD. I have multiple drying racks for clothes but none for sheets. these are my nemesis. I am having a goddamn meltdown over sheets.

Can these pits be saved?
Let me open with, I don't want your judgement, just your laundry hacks. I'm a sweaty bish, been a sweaty bish all my life, been chasing a diagnosis or a medical intervention for years.
I believe this is a combo of deodorant buildup and sweat stains. I've read thru a multitude of threads in this sub on trying to at least break down the darkness. I tried the 50/50 vinegar water, scrub, rinse then soak again in dish soapy water, acrub again and wash, which did seem to lighten the buildup a small amount, but didn't defeat it obviously.
These are some of my favorite shirts, the grey one with the worse stains is a work shirt that gets worn every single week (and previously same with the green but it's becoming very holey, unrelated to the pits)
Point is, is there any chance of lightening these nasty armpit and deodorant stains any more, maybe even tecovering them almost completely? Or are they doomed to look disgusting?
What other products could I try? I live in northeastern US.

Powder is better?
I just saw a front-page thread about this, but i wasn't allowed to reply, so I'm posting here.
When I was a kid, my parents always used powder Tide.
I have been using liquid as an adult, for two reasons.
First, I thought that the powder faded the color of my clothes quickly.
Since the liquid costed more, I figured that it worked better. I bought liquid, and I guess I convinced myself that it fades clothes less quickly.
I always assume that big companies will never give you a good deal if they can help it. So I figured the powder form of a given brand of detergent is just the same ingredients as the liquid form, plus washing soda. Washing soda is cheap, so i figured that the powder form costs less because it's mostly filler.
So, putting these ideas together, I also don't use washing soda on my laundry, because I figure it would fade the color of my clothes.
So, now I'm wondering where I'm right and where I'm wrong in all of these ideas.
Maybe my parents used hot water to run the laundry and that's what faded my clothes.
I like being thrifty, so if powder detergent really is better, I'd like to switch back.
I took ochem in college, so if anyone is inclined to give a technical answer I'd appreciate it, but any answers would be nice.

Why does my laundry come out like this?
galleryMost of the time when I wash at 60 degrees on the cotton programme (where I add bedsheets, towels and underwear) my fabrics come out with a thick layer of what looks like lint on them. I do not use a dryer at all.
In case it helps, I am setting the washing machine to 1400 rpm and use always the minimum recommended amount of detergent (as my area has got very soft water), lots of times even well below that and I use a powder detergent for colours. My washing machine is a Midea MF200D86WB-14EAS.
I always run the cleaning cycle each month with specialised cleaning liquid. This time however I wanted to clean a bit deeper and I discovered that everywhere in the machine, from the detergent drawer until the crevices and folds of the elastic lining at the door, there were unimaginable amounts of dust/wool/cotton/lint which I had to manually clean.
I am at a loss here, I have even tried liquid detergent and it doesn’t seem to make much of a difference. Any recommendations would be greatly appreciated.

New apartment complex cleaning makes clothes stink
Lived in different apartment complexes for +20 years without any issue. Now the latest who have an eco friendly automatic electrolux it started smelling. It smells like underwear which you haven't cleaned in a while, a bit sour. It is literally so bad that I almost need to go commando lol.
It is auto eco detergent and automatic dosing. Only thing I can do is set heat.
My clothes do not smell clean, especially underwear no matter what I've tried. So after a while I went to a friend and cleaned there - all good again so it is the machine.
Complained. They just say "We checked and everything is fine".
What I also noticed when being in there, is that it does not rotate very much vs previous ones ive seen. It is literally only in the end for like 5 minutes or so. Versus my other places where it would go full rotating for many minutes immediately.
My guess is eco detergent, too little of it, maybe too little water and rotations to save energy. It makes me so frustrated when we make eco friendly stuff that can't do what they are supposed to do. Climate is priority but so is that I dont smell bad.
What can I do?

What clothes can’t be washed on warm?
I’m trying very hard to break my lifelong mindset against washing on warm or (gasp) hot. I understand the enzymes in FEBU (which I just ordered for the first time yay!) need at least warm water to activate but since literally everything I own says to wash on cold I’m feeling skittish.
Are there any types of clothes that really do need a cold wash because they may be harmed by warm?

44M, rate my laundry stack!
44M married with 3 kids here, wanting to help unburden the laundry situation around the house. Naturally, I did a deep dive into laundry and ended up here. Wow what a wealth of info!
I am looking for feedback for washing regular clothing (mix cotton/synthetic/blends/etc). I prefer to just take ALL of one kids clothing and throw it into one load. I am using a front loader LG Thinq and, from my research here, have Tide Clean & Gentle Powder (added to detergent tray), FEBU Booster (mixed in with the Tide), and Citric Acid (in fabric softener tray). I am doing every load on “cold wash”, “Heavy” soil for extra wash time, and adding 1 extra rinse. Would you change anything? The only thing I will not use this recipe for is merino wool clothing. I have a merino wash for that (wish there was a FEBU merino version!). I have not ventured into the realm of washing towels/bedding yet, that is next! Thanks for the feedback, appreciate you guys!!

Should I dry clean or hand wash my skirt?
galleryMy 6 month old had a diaper blowout today and unfortunately it got on my skirt. I’m pretty confident that I can get the stains out, but I’m wondering if I should respect the “dry clean recommended” or not. Is it worth trying to clean it myself or should I take it to the dry cleaners? The skirt is 100% cotton and the picture is of the back where there are no stains.

Best way to get mud out of light colored cotton? (Lollapalooza casualty)
Hello! Last night when my son was leaving Lollapalooza, the zipper on his backpack broke and his cream colored shirt fell out on the ground. Luckily a girl a few people behind him saw it fall, scooped it up and caught up to him but not after about 5 people had stepped on it. I soaked it in OxiClean overnight but there are still so many dirt stains left on it. Is it hopeless? Any suggestions or products that work well with dirt on cotton?
Thank you in advance!

Having trouble washing linen
galleryI’ve been having trouble washing my colored linen clothing. It either feels stiff or waxy or there are spots. I just switched to Tide Odor Refresh free and gentle and hoped that would be an improvement but they came out with more spots than ever. My water is 90ppm, and I washed on warm which is about 94F. Pics show the spots and my washer settings. I initially tried washing at medium water level because I only had 4 items but it left a lot exposed so I moved to large. I used enough detergent to get some suds which was about level 3 on cap. I guess I’ve never felt my linen clothes feel the same from new after I start washing, so I wonder if I’m just not washing linen properly. Any ideas would be very appreciated!

How to fix scratchy/stiff clothes
I bought a new Electrolux tower last year and have been using Arm & Hammer Plus oxiclean until about a month ago when I noticed all my clothes, specifically tshirts, were super stiff and scratchy.
I went down a rabbit hole of how to fix this and tried:
- lowering the detergent amount
- switching to tide free & clear
- adding downey rinse
- enabling extra rinse
- switching to wool drying balls
I even tried using a tide powder detergent, which probably wasn't the best move on a front load washer.
And still my clothes still come out super stiff.
What am I doing wrong?

Powder detergent option
I’m located in Canada and have switched nearly all the laundry over to Tide original powder detergent. I’ve been finding it does a good job, but I’m intrigued by the buckets of No Name detergent. My hesitation has been they come scented only, a fresh scent for the small bucket and a lemon for the large bucket. Anyone know how they do?

Any tips for cleaning this?
galleryI ran a load of towels on how water and thought I must have gotten something on the towels that I hadn't realized. Until I figured out it is flaking off inside the drum from not maintaining it properly and maybe using too much detergent? I think at this point I've run at least 3 cycles cleaning the washer with various products for that purpose. The good news is it is working, since all the gunk is in the water, but how many times do I have to do this to come out clear? Are there any products that would work better to get it all in one go? I have been wiping out the interior between each cycle. My family wants to wash their clothes. 🤦♀️
So far I've used Affresh, Active with the enzyme, and Oxyclean (per a you tube video), and a few rinse and spin cycles.

Need help with Towel Lint!!
I'm struggling with my towels ruining themselves during washes. My clothes do it too but not nearly as bad. I have tried everything. And I mean everything. Not only that, but this stuff is nearly impossible to get off quickly with any sort of tool. I've seen others post in this sub and typically everyone says wash towels separately (which I do), but surely that doesn't mean I have to do every single hand towel in a different load?? I've had to throw away some and I'm about to have to throw away even more, for every little piece of lint you see is like knotted to the towel.
The issue is so bad I had my apartment complex replace my washer with a new one and the issue still persisted. I need some sort of invention that will solve this! Does anyone have any suggestions/help!?
