Dishwashing liquid: what's actually in it?

Format note: dishwashing liquid is not food, so there is no nutrition section on this page — nutrition does not apply, and no nutrition numbers are invented, estimated or borrowed. Each panel below quotes the verbatim ingredient list as printed. Where a list could not be verified, the product is in "seen but not verified", never panelled on a guess. Baby bottle cleansers are included on this page as dishwashing liquids for baby bottles — they are a distinct sub-type, flagged as such.

This page does not give a health score, a ranking or a "best" pick, and it does not show prices (they change weekly). It does not make efficacy or safety claims beyond what the label states — it describes ingredients as printed.

Pigeon Liquid Cleanser (incl. 200ml) — baby bottle cleanser

Pack size: 200ml · Made in: not stated (as printed)

As printed: Purified Water (Aqua), Sodium Citrate, Alcohol, Propylene Glycol, Sucrose Laurate, Potassium Carbonate, Citric Acid, Sodium Benzoate, Fragrance.

Flag — medium strength, not a retailer ingredient section: this 9-item list is quoted from a Singapore listicle (The Wedding Vows SG, updated 27 Jan 2023), which presents it as the product's contents — but it is a secondary listicle, not a retailer ingredient section. It is corroborated verbatim, same 9 items in the same order, in Australian retailer ingredient sections: Chemist Warehouse AU (Pigeon Liquid Cleanser Refill 650ml — link) and Ramsay Pharmacy AU (450ml — link), plus an India pack transcription. That corroboration is for the same product name in other markets, not a Singapore pack read — the SG 200ml pack needs a pack-photo check to confirm it carries this formula. Conflict flagged: a different Pigeon product, "Pigeon Naturals Liquid Cleanser 200ml" (India), carries a different formula — Lauramine Oxide, Cocamide Monoethanolamine, Lauramidopropyl Betaine, Sodium Citrate, plus Aqua, Sodium Laureth Sulfate, Sodium Benzoate, Polysorbate 20, Glyceryl Caprylate, Potassium Carbonate, Propylene Glycol, Citric Acid, Fragrance (TrueMeds India). Do not merge the two: the 9-item list above is the classic Liquid Cleanser; "Naturals" is a separate variant. Baby bottle cleanser No SLES in classic list Medium strength — verify on SG pack

Nutrition — what the numbers say

Nutrition information does not apply to dishwashing liquid, and it is not printed for it. Dishwashing liquid is not food or drink: it has no energy, protein, fat, carbohydrate, sugars or sodium content to compare, and no Nutri-Grade. This page therefore does not invent, estimate or borrow any nutrition numbers, and it keeps comparing what the packs do print — the ingredient list — exactly as before.

How to read a dishwashing liquid pack — the jargon, in plain English

SLES (sodium laureth sulfate) / LAS (sodium linear alkylbenzene sulfonate)
The main cleaning (surfactant) ingredients in most mainstream dishwashing liquids. SLES is the ethoxylated form; LAS is the workhorse anionic surfactant named on the Mama Lemon SDS fragment and the Vietnam Sunlight list. The Pigeon classic list is notable for containing neither.
Cocamidopropyl betaine
A co-surfactant used alongside SLES in most mainstream lists; it helps lather and thickens the formula.
Sucrose laurate
A sugar-based surfactant in the Pigeon classic list — a mild, food-derived cleaning ingredient, which is why it appears in a baby bottle cleanser rather than a mainstream dish liquid.
MI/MCI — methylisothiazolinone / methylchloroisothiazolinone
A preservative pair that recurs across the non-SG lists found (Sunlight Vietnam, Koh Australia, Morning Fresh Australia) and the Bio-Home generic statement. Named in full on the pack when present.
DMDM hydantoin
Another preservative, named in the Morning Fresh (Australia) and Sunlight (Vietnam) lists. It is a preservative, not a cleaning ingredient.
SDS ≠ pack list
A safety data sheet names only hazardous ingredients (for Mama Lemon, a single surfactant) — it is not the full ingredient list, and it must not be presented as one. The same applies to detergent-regulation band declarations ("15-30% anionic surfactants"), which give ranges, not a verbatim list.
Antibacterial
A label claim, not an ingredient. An antibacterial dishwashing liquid names its antibacterial active in the list when the pack prints one (for example hydroxydichlorodiphenyl ether in some Tollyjoy/Idocare descriptions from the first pass — not verified here). Without the list, the claim alone tells you nothing about the ingredient.

What this page is not

Sources and method

Checked 5–6 November 2026. First pass (5 November 2026): retailer ingredient sections read in a live browser — Pigeon Baby Liquid Cleanser, Tollyjoy Baby Antibacterial and non-antibacterial, Sunlight Lemon 100, TP 706 Lemon and Idocare Summer Citrus recorded as verified with full lists (texts not retained for all). Re-verification pass (5 November 2026): ~30 web searches across FairPrice, Cold Storage, Giant, Sheng Siong, Watsons, Guardian, RedMart, Lazada SG, Shopee SG, Don Don Donki, Mustafa, Meidi-Ya, Le Petit Depot, Little Farms, brand SG sites, Open Food Facts and SDS repositories — no FairPrice, Cold Storage, Giant, Sheng Siong, Watsons, Guardian, RedMart, Lazada SG or Shopee SG product page with an ingredient section surfaced for any of these products, and site: queries returned nothing relevant. No rate limits or fetch failures were encountered — the gap is absence of indexed ingredient content, not a block. Non-SG lists found (Sunlight Vietnam, Morning Fresh Australia, Koh Australia, Fairy UK, Axion US SDS, Ecover German partial) are documented in the research notes only and are not panelled as SG packs. Full per-fact source list is in the accompanying research notes.
