Talk:Dishwashing liquid

Usefulness of per-brand market shares

There's a whole section dedicated to the detailed breakdown of market share percentages in each country per brand. I don't see the usefulness of this. Unless you're a dishwashing soap investor, this info is completely uninteresting, useless, and clutters the article. Not to mention it's very unencyclopedic. I vote for removing the section entirely, or at least listing the known brands without the percentage breakdowns. Ericobnn (talk) 03:01, 20 March 2015 (UTC)

Dish soap in gardening?

Hi! Here's the Google books search for dish soap:https://www.google.com/search?q=dish+soap&biw=360&bih=615&tbm=bks&ei=tC-qVPuDKI_ZoASS7oHYAQ&start=0&sa=N&dpr=3

There's some books that mention dish soap in gardening to protect against pests. I didn't look into it too much but the link's above if anyone interested in researching that. Thanks, Bananasoldier (talk) 06:34, 5 January 2015 (UTC)

Also http://m.state-journal.com/spectrum/2015/01/03/cold-weather-gardening-kale a small reference. Bananasoldier (talk) 03:34, 6 January 2015 (UTC)

Notable brands

I think notable brands needs its own section. Is it considered biased to mention some brands but not others? Maybe there should be a list? Please discuss! Thanks! Bananasoldier (talk) 06:40, 5 January 2015 (UTC)

• Mention popular Korean dish detergent:http://m.koreatimes.co.kr/phone/news/view.jsp?req_newsidx=12020 Bananasoldier (talk) 05:15, 9 January 2015 (UTC)

There is a series of dishwashing market research summaries by country (looks like about 60 or 70 countries) on the Euromonitor International website. Possibly this information could be best summarized and presented in a table? It is current as of 2014, and has information on dishwasher detergent vs. hand dishwashing liquids. While using this info may cause some maintenance issues, it could be an interesting global perspective. I'm willing to tackle it if others think it could be useful. — Grand'mere Eugene (talk) 03:52, 11 January 2015 (UTC)

Update: First, I decided to use prose instead of a table. Is it too late for a DYK?

I also elected to cite the parent page for Euromonitor International's dishwashing market reports instead of the 80 direct links to each country's summary page. Sorry I just didn't have time to cite each page individually, but links are on the right side of the page I did cite.

Cheers! — Grand'mere Eugene (talk) 05:32, 13 January 2015 (UTC)

Requested move 5 January 2015

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: not moved. No consensus on the proposals and concerns raised that liquid and detergent are different things. Number 57 17:15, 8 February 2015 (UTC)

---

Dishwashing liquid → Dishwashing detergent – "Liquid" is not the best name because there are non-liquid dishwashing substances, and this article should cover them. "Dishwashing soap" may be an option, but it seems that the industry producing these products calls them "detergents" A change to either "soap" or "detergent" would be an improvement but I am not sure which is best. Blue Rasberry (talk) 19:57, 5 January 2015 (UTC)

• Move to Dishwashing soap. I feel it's more reader-friendly. Regardless, thanks for bringing this up. Bananasoldier (talk) 22:42, 5 January 2015 (UTC)
  • Comment soap is a different substance from detergent (which is why one works better in hard water than the other) -- 65.94.40.137 (talk) 04:24, 10 January 2015 (UTC)
• I agree with the original nomination, detergent is a stronger word than soap in this case, and would encompas ganular dish cleaners, pods, tablets and such. --NickPenguin_(contribs) 01:01, 6 January 2015 (UTC)

• Support moving to Dishwashing detergent - I admit I'd rather this be named "washing-up liquid" but unfortunately we can't, so Dishwashing Detergent will have to do . –Davey2010 ^{Merry Xmas / Happy New Year} 02:26, 6 January 2015 (UTC)
• Support move to Dishwashing detergent per Blue Rasberry and NickPenguin. This will also expand the article's scope. NorthAmerica¹⁰⁰⁰ 04:52, 6 January 2015 (UTC)
• Dishwashing detergent... Hmm... Also, should facts about detergent be mentioned in the Dishwashing liquid article? Qwertyxp2000 (talk) 06:08, 6 January 2015 (UTC)

Yes, I should - dishwashing liquid is a type of detergent. Qwertyxp2000 (talk) 06:13, 6 January 2015 (UTC)

Guys? I think we should help the Detergent article too. It lacks history as well. Qwertyxp2000 (talk) 06:15, 6 January 2015 (UTC)

• Support, but for the Dishwashing soap. I agree in moving. "Dishwashing soap" is general and we could add much more things into this article, including facts about dishwashing liquid. Qwertyxp2000 (talk) 06:11, 6 January 2015 (UTC)
• There's more ghits for dishwashing soap (1,220,000) versus (dishwashing detergent (678,000), so soap would probably be the better choice. Also that's had a redirect since 2006, and detergent did not have a redirect yet, so probably the more likely search term as well. --NickPenguin_(contribs) 00:32, 7 January 2015 (UTC)
  • But it's not a soap, it's a detergent -- 65.94.40.137 (talk) 04:24, 10 January 2015 (UTC)
• Support as proposed with lesser preference to "soap". The title suggests the most common dishwashing liquid Red Slash 00:25, 8 January 2015 (UTC)
• Oppose. Dishwashing liquid and Dishwashing detergent are two vastly different products, and should never be conflated. In fact, they should be separated out into two separate articles. The former is for hand washing, the latter is for automatic dishwasher use. The former is usually/often not even a detergent, but rather a soap, which is another reason the two should not be conflated. Each product has completely different properties, and completely different issues (consumer, industrial, environmental, economic, political), and one cannot ever be substituted for the other. Softlavender (talk) 00:27, 11 January 2015 (UTC)
  • One problem I've run into while finding references is that the terms are used so loosely (sometimes dish soap is called hand dishwashing detergent and dishwashing liquid sounds like any liquid that is involved with washing dishes) that it's hard to tell if they're talking about hand or machine. The soap companies often sell both types of products under the same brand or multi-use products for both hand and machine washing, and that makes it even more ambiguous. I feel that any sort of chemical that washes dishes should be put together. Thanks, Bananasoldier (talk) 00:58, 11 January 2015 (UTC)

"The soap companies often sell both types of products under the same brand or multi-use products for both hand and machine washing". This isn't true. As I mentioned above, one cannot be substituted for the other. Try it some day and you'll find out the hard way. Also as I mentioned above, if something is labeled "dishwashing detergent" it's for the automatic dishwasher, never for hand washing; therefore, we can't put handwashing dish products in an article called "dishwashing detergent". Also as I mentioned above, the products for handwashing are generally soaps (chemically), and the products for machine washing are always detergents (chemically). Softlavender (talk) 01:30, 11 January 2015 (UTC)

Apologies for my assumptions. Confusion on my part. This notes some of the chemical differences between hand and automatic. I don't know why this author calls it "hand dishwashing detergents" though. Best, Bananasoldier (talk) 02:30, 11 January 2015 (UTC)

"I don't know why this author calls it 'hand dishwashing detergents' though." I don't know. A hand dishwashing product is never labeled "dishwashing detergent", although some are occasionally labeled "dish detergent". Softlavender (talk) 02:39, 11 January 2015 (UTC)

• I would Oppose to move the article actually. It is already only mentioning Dishwashing Liquid and not anything else. Qwertyxp2000 (talk) 04:05, 14 January 2015 (UTC)
• Oppose – the article's primary focus is specifically upon dishwashing liquid at this time, and has been significantly expanded very recently. I struck my initial comment above. NORTH AMERICA¹⁰⁰⁰ 05:12, 14 January 2015 (UTC)
• Support: Even if it doesn't cover the increasingly common non-liquid dishwashing products, it obviously should. Keeping the article at a misleading name will only impede improving the article (people will actively resist additions that are not about liquid detergent), and a reductio ad absurdum of the intent of our naming policies. 10:36, 15 January 2015 (UTC)
• Oppose - the article covers dishwashing liquid (which in UK English is called "washing-up liquid" as mentioned in the article). It does not cover powder or other forms of detergent used for dish washing.  — Amakuru (talk) 16:15, 22 January 2015 (UTC)

New article - Dishwasher detergent

I just created Dishwasher detergent. I understand and agree that there should be two separate articles for the product for cleaning dishes by hand versus the ones used inside a machine.

@Softlavender: - thank you especially for articulating this. Blue Rasberry (talk) 22:04, 21 March 2017 (UTC)

I believe there are more articles out there on accidental ingestion of detergent packets.

On a side note, I ran across articles on people using soap as a lubricant to place a bridge. I also ran across other articles that used dish soap to remove stuck people and animals. I didn't record the link because I thought they might be trivia. Should I retrieve them? Bananasoldier (talk) 06:01, 6 January 2015 (UTC)

Section on common dishwashing detergent ingredients?

What do you think? Would it be unnecessary/redundant/difficult to put together or a possible addition? I haven't looked into any sources on this. Thanks, Bananasoldier (talk) 05:28, 6 January 2015 (UTC)

[[User:Bananasoldier has done great work finding all the above refs and must be the most familiar of any editors with their contents having done so. There are several 'citations required tags' in the article as is. Does he know if any of the refs he has found might help? It would take as much effort again for others to duplicate his learning.SovalValtos (talk) 22:25, 10 January 2015 (UTC)

Hi @SovalValtos:! Are these the citation needed sentences you're referring to?

• "Dawn, which is the leading brand in the United States,[citation needed] and Joy." Found by another editor!
• "Some brands offer differentiating features, such as Dawn Hand Renewal with Olay Beauty[12][unreliable source?]"
• "Ajax Triple Action, which offers cleaning, antibacterial properties, and can be used as a hand soap.[13][unreliable source?]"

These I haven't found citations to because I've only searched "dish soap". I am very sure that the links above won't cover them. Perhaps a search like "bestselling dish soaps"/"bestselling dishwashing detergents" will yield results. Maybe searching for "Dawn leading brand" or something more specific. Some of these sentences we might just throw out because they sound a little like advertising. Bananasoldier (talk) 22:34, 10 January 2015 (UTC)

Soap in punishment

Dishwashing liquid has also been administered orally as a substitute for [[soap]] as a form of [[corporal punishment]]. This is often colloquially referred to as [[washing out mouth with soap|washing the mouth out with soap]] or another similar phrase. However, this use carries health risks and has declined substantially in recent decades. Dishwashing liquid has also been used as a stain cleaner. These sentences got lost in the edits (probably because they're unreferenced). I'll leave them here just in case somebody's interested in finding refs for them.Bananasoldier (talk) 07:00, 8 January 2015 (UTC)

New article - Phosphates in detergent

I just created phosphates in detergent. On that article's talk page I described how I moved content about "phosphates in detergent" from these articles to there.

• Dishwashing liquid
• Dishwasher
• Laundry detergent
• Detergent

I put a brief summary of the concept here and am directing readers there for a fuller presentation. I did this because the concept was forked by being independently developed in all these articles, when instead they should all point to one central article.

Skin sensitivity, effect of dish soap on different surfaces, figures and captions

Some areas that I want to improve on this article include adding some ideas to “Common ingredients” and “Primary uses”, changing the images and captions. Regarding adding ideas to “Common ingredients”, I’m planning to add information on ingredients in dishwashing liquid that might help lessen the effect of skin sensitivity. For “Primary uses”, adding onto the part of dishwashing liquid affecting surfaces, I want to add the effect of dishwashing liquid on different surfaces. Regarding changing the images and captions, I’m planning to replace some images that have irrelevant background content and fixing captions and pictures so that the captions are as precise as possible, and pictures and captions fit each other well.

Handwashing vs. machine dishwashing

This atrticle often confuses between detergents for handwashing and machine dishwashing, uses terms interchangeably (that I'd argue aren't interchangeable). It isn't confusing only from informational, but also from stylistic standpoint. I suggest keeping information about detergents for machine dishwashing to minimum (for introduction, comparison or safety). Other information should be moved to dedicated article Dishwasher detergent 46.34.246.110 (talk) 08:35, 29 April 2024 (UTC)

Suggested Re-Organization for Safety and Composition

Hi all, I've been working on trying to find a way to reorganize the Composition and Safety portion of this article. It seems to me that the two could be separated into two different headings. The information can seem to be fairly cluttered and I thought this might be a better way to organize the heading. I also might consider bulleting out the safety portion of the document.

Composition

Dishwashing liquid may contain bleach, enzymes, and rinsing aids. The main ingredient is water; the main active ingredients is detergent. Dishwashing liquid has detergent rather than soap because the soaps would react with any minerals in the water to form soap scum. There are other thickening and stabilizing agents in the dishwashing liquid as well.

Hand dishwashing detergents utilize surfactants to play the primary role in cleaning. The reduced surface tension of water and increased solubility of modern surfactant mixtures allow water to run off dishes very quickly. Additionally, surfactants remove grease and food particles to aid in cleaning dishes. They may also provide foam.

Other ingredients may include hydrotrope, salts, preservatives, fragrances, antibacterial ingredients, and dyes. Preservatives prevent micro-organisms' proliferation within the liquid. Antibacterial ingredients make it difficult for bacteria to survive on surfaces.

Some alternatives for dishwashing detergents may be homemade, using ingredients such as borax, essential oil, eucalyptus oil, leftover cooking oil, and bar soap, among others.

Surfactant design

There has been comparisons of different surfactants that reduce the surface tension of water to determine the most efficient dishwashing liquid. Lowering of surface tension helps with the cleaning processes. A study showed that anionic surfactant combined with non-ionic surfactant worked better than anionic and amphoteric surfactants combined. Another study found that cationic and anionic surfactants combined worked better than non-ionic and anionic surfactants combined. Anionic and amphoteric surfactants combined are the least effective out of the three.

Safety

Some dishwashing liquids can harm household silvers, fine glassware, anything with gold leaf, disposable plastics, objects that are brass, bronze, cast iron, pewter, tin, or wood, especially under hot water and the action of a dishwasher. Dishwashing liquid components are also harder to rinse off from rough surfaces than smooth surfaces, increasing the chance of accidental ingestion.

In 2010, the United States FDA raised health concerns over triclosan, an antibacterial substance used in some dish liquids. Elsewhere, triclosan has been found to create problems at wastewater treatment plants, whereby it can "sabotage some sludge-processing microbes and promote drug resistance in others." As of 2014, at least one US state has banned triclosan in dishwashing liquids.

Some dishwashing products contain phosphates. Phosphates make dishes cleaner but can also cause harmful algal bloom as the wastewater goes back to the natural environment. Because of this, many places have banned this component. Phosphates can also cause harmful health effects upon skin contact.

Many dishwashing liquids contain perfume which can cause irritant or allergic contact dermatitis. It can also cause hand eczema. Those with sensitive skin should persuade someone else to do the washing up. Recent research has found that Blackcurrant seeds are helpful for lessening the effects of allergies, due to its hydrophobicity. Surfactants that are anionic also showed promising results in preventing skin irritation.

Accidental ingestion of rinse aids (components within dishwashing tablets) can lead to vomiting. Chitens (talk) 04:45, 22 October 2024 (UTC)
