Amazon Mouthwash Price October 2026: Cost Per 100ml, Rs. 44 to Rs. 807

Rs. 333 for 750 ml is Rs. 44.40 per 100 ml, the lowest figure among the 25 listings seated. 4.3 stars from 3,554 ratings. Amazon prints Rs. 44 per 100 ml on this tile itself, which matches our own division to the rupee.

Hold Rs. 44.40 for the rest of the page. The dearest listing here works out at Rs. 807.60 for the same 100 ml — 18.2 times as much, on the same shelf, in the same search session. Note also what beats what: this three-bottle pack is cheaper per 100 ml than the same line's four-bottle pack further down, which is the first of several places on this shelf where buying more costs more per millilitre.

• Selling price: Rs. 333

• Price per 100 ml: Rs. 44.40
• How that volume was established: 3 x 250 ml stated in the title, three bottles shown in the listing photograph

Rs. 470 for two 500 ml bottles is Rs. 47.00 per 100 ml — a litre of Listerine Cool Mint for Rs. 470. 4.4 stars from 29,824 ratings. Amazon's own printed rate on the tile is Rs. 47 per 100 ml.

Now remember this card, because a litre of Listerine Original appears later on this page at Rs. 8,076. That is Rs. 807.60 per 100 ml, 17.2 times this one, and both listings came back in the same search session on the same morning. They are different Listerine variants and one is an imported listing, but the shelf presents them side by side with nothing to tell a shopper that the unit economics are seventeen-fold apart.

• Selling price: Rs. 470

Rs. 279 for 500 ml is Rs. 55.80 per 100 ml. 4.0 stars from 66 ratings — the smallest pool in this chapter by a wide margin. The listing photograph shows two bottles branded 'Totalflux Mintfresh'.

It sits between the two national brands on rate, and far below them on evidence. The Colgate listing above it has 3,554 ratings and the Listerine listing above that has 29,824. Eleven rupees per 100 ml separates this card from the cheapest Listerine. Whether that is worth it is a judgement this page does not make: we did not open, use or compare any product here, and a rating count measures attention rather than quality.

Rs. 429 for 750 ml is Rs. 57.20 per 100 ml. 4.4 stars from 32,837 ratings — the largest pool among the 25 seated.

Compare it with the card above: the same Listerine Cool Mint at Rs. 47.00 per 100 ml in a 2 x 500 ml pack. Ten rupees per 100 ml separates three small bottles from two large ones of what the titles describe as the same product. On this shelf the bottle size moves the rate more reliably than the brand does, and neither is visible from a price tag alone. Amazon prints Rs. 57 per 100 ml on this tile, matching our figure.

• Selling price: Rs. 429

Rs. 580 for 1,000 ml is Rs. 58.00 per 100 ml. The same Colgate MaxFresh Plax line in a three-bottle, 750 ml pack opened this page at Rs. 44.40 per 100 ml. Buying the larger pack costs 31% more per 100 ml. 4.3 stars from 3,554 ratings — the same rating pool as the smaller pack, because the listings share it.

This is the single most useful card on the page for a shopper. The instinct that a bigger pack is better value is simply wrong here, and nothing on either tile signals it except the per-100-ml rate Amazon prints in small type. Both figures are Amazon's own and both match our arithmetic. Prices change continuously and this relationship may not hold tomorrow — which is exactly why the rate is the thing to read.

• Selling price: Rs. 580
• Volume: 1,000 ml
• Price per 100 ml: Rs. 58.00

Rs. 440 for 750 ml is Rs. 58.67 per 100 ml. 4.3 stars from 3,189 ratings.

Listerine Original appears three times on this page: here at Rs. 58.67 per 100 ml, as a single 500 ml bottle at Rs. 79.80, and as two 500 ml bottles at Rs. 79.80 again. The three-small-bottle pack is 26% cheaper per 100 ml than either of the large-bottle listings, and the twin-pack of large bottles saves nothing whatsoever against the single. All three figures are Amazon's own printed rates as well as ours. The second chapter of this page is about that pair.

The search title reads 'Listerine Cavity Fighter Mouthwash Liquid, Removes 99.9% Germs, prevents cavities, 250ml C…' and stops. The product page's Unit Count field reads 750.0 Millilitres, the listing photograph shows three bottles, and Amazon's own printed rate is Rs. 64.00 per 100 ml — which is Rs. 480 divided by 750, not by 250.

Divided by the 250 the title appears to state, this would have come out at Rs. 192 per 100 ml and been reported as one of the dearest listings on the shelf. The words 'Combo Pack of 3' fall off the end of a search title capped at about ninety characters. We opened this product page precisely because our figure and Amazon's disagreed, and Amazon's was right. 4.4 stars from 9,415 ratings.

• Selling price: Rs. 480
• Volume: 750 ml
• Price per 100 ml: Rs. 64.00

Rs. 157 for 250 ml is Rs. 62.80 per 100 ml, against Rs. 44.40 for the same family in a three-pack. 4.3 stars from 2,482 ratings.

Rs. 157 is a much smaller number than Rs. 333, and it buys mouthwash at 41% a worse rate. That is the whole case for reading unit prices rather than prices on a shelf like this one. It is not an argument for buying three bottles: a product that goes stale, gets lost at the back of a cabinet or turns out not to suit you is not cheap at any rate per 100 ml. The arithmetic tells you what you are paying for volume and nothing about whether you want the volume.

Rs. 132 is the smallest amount of money any listing on this page asks for. At 215 ml that is Rs. 61.40 per 100 ml, which is the ninth-cheapest rate here. 4.1 stars from 778 ratings.

Cheapest tag and cheapest mouthwash are different questions with different answers, and this card is where they part company. Eight listings on this page deliver mouthwash at a better rate and every one of them costs more to buy. For a shopper who wants to spend the least today, this is the card. For a shopper who wants the least cost per rinse, it is not. This page measures the second and says nothing about which is the sensible thing to want.

• Selling price: Rs. 132

Rs. 399 for 500 ml is Rs. 79.80 per 100 ml. 4.5 stars from 2,106 ratings. Amazon prints Rs. 79 per 100 ml on this tile.

Now read the next card. It is the same Listerine Original in a pack of two 500 ml bottles at Rs. 798 — exactly twice this price, for exactly twice the volume, at exactly the same Rs. 79.80 per 100 ml. A twin-pack that costs precisely double is not a bulk discount; it is the same offer presented as a bigger one. Nothing improper is alleged in that: a seller is free to price a multipack at the sum of its parts, and this page simply reports that this one does.

• Selling price: Rs. 399
• Volume: 500 ml
• Price per 100 ml: Rs. 79.80

Rs. 798 for 1,000 ml is Rs. 79.80 per 100 ml. The single 500 ml bottle above is Rs. 399, which is Rs. 79.80 per 100 ml. The twin-pack costs exactly double and saves exactly nothing. 4.7 stars — from five ratings.

And the three-bottle, 750 ml pack of the same Listerine Original, five cards back, is Rs. 58.67 per 100 ml. So within one product on one shelf read in one session: Rs. 58.67, Rs. 79.80 and Rs. 79.80 per 100 ml. The best rate is the middling-sized pack, the worst are the two large-bottle listings, and the only way to see any of it is to do the division or read the small grey rate Amazon prints. Note the five-rating pool on this card before weighing its 4.7.

Rs. 361 for 500 ml is Rs. 72.20 per 100 ml. The three-bottle 750 ml listing of the same Listerine Total Care Cavity Fighter is Rs. 64.00 per 100 ml. 4.4 stars from 9,415 ratings — the same pool as the three-pack, which the two listings share.

Here the multipack does save money: about 11% per 100 ml. Set that against Listerine Original, where the twin-pack saved nothing, and Colgate MaxFresh Plax, where the larger pack cost 31% more per 100 ml. There is no rule on this shelf about whether bigger is better value. There is only the rate, listing by listing, and it has to be read each time.

Rs. 215 for 250 ml is Rs. 86.00 per 100 ml. In the same read, Listerine Total Care Sensitive in a three-bottle 750 ml pack came back at Rs. 460, which is Rs. 61.33 per 100 ml. The single bottle is 40% dearer per 100 ml. 4.4 stars from 97 ratings.

That makes four Listerine variants on this page whose single bottles and multipacks differ by 0%, 11%, 26% and 40% per 100 ml. The spread is not a policy and there is no suggestion here that it should be one. It is the normal consequence of many sellers listing many pack configurations of the same product, and the only defence a shopper has against it is the division.

The title reads '330ml'. The product page's Unit Count field reads 497.0 Millilitres, and Amazon's own printed rate is Rs. 69.42 per 100 ml, which is Rs. 345 divided by 497. Divided by the 330 the title states, we would have published Rs. 104.55 and placed this listing in the dear half of the page. 4.4 stars from 379 ratings.

Two of the 38 listings whose volume we could read from a title had the wrong volume in that title, and both were caught the same way — by our arithmetic disagreeing with the rate Amazon prints, and then opening the product page to see which was right. Both times Amazon's rate was right. That is worth knowing before trusting any unit-price page, including this one.

Rs. 148 for 215 ml is Rs. 68.84 per 100 ml. The Himalaya Miswak bottle earlier on this page is the identical 215 ml size at Rs. 132, which is Rs. 61.40 per 100 ml. Sixteen rupees of price becomes 12% of rate between two flavours of one brand at one volume. 4.1 stars from 520 ratings.

This is the smallest meaningful gap on the page and it is still worth 12%. It is also the cleanest like-for-like on the shelf: same brand, same line, same bottle, same alcohol-free formulation as printed, and nothing between them but flavour and sixteen rupees. We did not taste, test or compare either and express no view on which anyone should prefer.

Rs. 125 for 200 ml is Rs. 62.50 per 100 ml. 3.9 stars from 273 ratings — the lowest star average among the 25 seated.

Perfora appears twice in this read at Rs. 62.50 and Rs. 91.50 per 100 ml, the second being its 200 ml Lemon Mint at Rs. 183. One brand, one bottle size, a 46% difference in rate between two flavours. The newer brands on this shelf sit in the same Rs. 62 to Rs. 104 band as the national ones once you divide, which is not what the price tags suggest. Nothing here assesses formulation, ingredients or claims; 'activated charcoal', 'probiotics' and 'whitening' are the listing's own printed words.

Rs. 698 for 500 ml is Rs. 139.60 per 100 ml, roughly three times the cheapest rate on this page. 4.5 stars from 142 ratings. Amazon's own printed rate is Rs. 139 per 100 ml.

From here to the end of this chapter the listings stop being substitutable for the ones above. A fluoride rinse, an imported cinnamon mouthwash and a litre bottle shipped from abroad are not four versions of one purchase, and ranking them purely by rupees per 100 ml would be a misleading thing to do. They are seated because they are on the shelf and because the width of the range is the finding — not because this page thinks anyone should choose between them on rate. Nothing here is dental advice.

Rs. 2,060 for one litre is Rs. 206.00 per 100 ml, 4.6 times the Rs. 44.40 that opened this page. 4.6 stars from 512 ratings. Amazon prints Rs. 206 per 100 ml on the tile.

Imported listings are where the rate stops tracking anything a shopper can reason about from the product. Freight, duties, importer margin and small volumes all sit inside that figure and none of them is visible on the tile. This page does not claim the price is unreasonable; it reports that a litre here costs 4.4 times what a litre of Listerine Cool Mint costs five cards earlier, and that nothing on the shelf flags the difference except the rate itself.

Rs. 3,034 for one litre is Rs. 303.40 per 100 ml. 4.5 stars from 180 ratings. Amazon's own printed rate is Rs. 303 per 100 ml.

Two imported litres on one shelf, Rs. 2,060 and Rs. 3,034. The same search also returned a three-litre Crest Pro-Health listing at Rs. 7,645, which works out at Rs. 254.83 per 100 ml — cheaper per 100 ml than the single litre of the same product, and dearer than the Lavoris. There is no ladder here to climb. The imported end of this shelf is priced listing by listing and the only way to compare any two of them is the rate.

Rs. 14,234 for two litres is Rs. 711.70 per 100 ml — sixteen times the cheapest rate on this page. Amazon prints Rs. 711 per 100 ml on the tile, matching our division. 4.6 stars from 17,133 ratings, the second-largest pool among the 25 seated.

The rating pool is the strange part. 17,133 ratings is more than almost anything else on this page, and ratings on Amazon attach to a product rather than to a particular seller's listing of it, so a pool that size tells you nothing about this listing's price. We report the figures exactly as published and allege nothing about any seller: listing an imported product at an importer's price is ordinary and lawful. It is simply a very large number next to a very large number.

Rs. 8,076 for one litre is Rs. 807.60 per 100 ml. The first card on this page is Rs. 44.40. The ratio is 18.2 to one. Within the Listerine name alone the span is Rs. 47.00 to Rs. 807.60, which is 17.2 to one. 4.8 stars from 8,734 ratings — the highest average on the page.

Two litres of Listerine. Rs. 470 buys one of them in a two-bottle Cool Mint pack; Rs. 8,076 buys this one. They are different variants and this is an imported listing, so they are not the same purchase — but they are on the same shelf, returned by the same search, with the same brand name on the bottle and no visible signal of the gap other than the small grey rate. That is the page in one sentence.

On 30 listings in this read the number beside the price was Amazon's own per-100-ml rate. On this one it is Rs. 270, and the product page confirms that Rs. 270 is the M.R.P. The price is Rs. 236, so this is a 13% discount and not a rate at all. Our own division gives Rs. 118.00 per 100 ml. No star average or rating count is published.

Nothing on the search tile distinguishes the two kinds of number. Any tool — or shopper — that reads that field as a unit rate will report this listing as costing Rs. 270 per 100 ml, which is more than double what it does. We found the four exceptions by opening product pages, and they are all medicated rinses. This card prices a product and does nothing else with it: no efficacy, suitability or safety comparison is made or implied, and nothing here is dental, medical or pharmaceutical advice.

Rs. 130 against an M.R.P. of Rs. 149, confirmed on the product page. Our own division gives Rs. 81.25 per 100 ml. No star average or rating count is published on this listing.

All four listings in this chapter are chlorhexidine or professional dental preparations rather than the cosmetic mouthwash the rest of the page measures. They are seated for one reason: to document that the same slot on the same search page carries two incompatible kinds of number, with nothing to tell them apart. They are not ranked against the cosmetic listings, no claim is made about what any of them does, and a medicated antiseptic rinse is not something to choose on price. Speak to a dentist or pharmacist; nothing here is medical advice.

Rs. 156 against an M.R.P. of Rs. 179, read from the product page. Our own division gives Rs. 104.00 per 100 ml. No rating is published.

Three listings in a row is a pattern rather than an anomaly. The common thread across all four is that these are pharmacy-type preparations, several of them marked 'IP' or 'B.P.' on the bottle, sold through the same search results as cosmetic mouthwash. Why Amazon shows a maximum retail price on these and a per-100-ml rate on the rest is not something we can see from outside, and we allege nothing about it. No efficacy, safety or suitability claim is made about this product, and nothing here is medical or pharmaceutical advice.

• Selling price: Rs. 156
• Volume: 150 ml

Rs. 421 against an M.R.P. of Rs. 430 is a discount of nine rupees, or 2%. Our own division gives Rs. 210.50 per 100 ml, though the listing describes a concentrate, so even that figure is not comparable with a ready-to-use rinse. No rating is published.

End the page on its own limitation. A per-100-ml rate is a fair way to compare two bottles of the same kind of thing and a poor way to compare different kinds of thing, and this chapter is four examples of the second. Concentration, formulation, intended use and who a product is for all matter and none of them is priced here. Nothing on this page was bought, opened, used or tested, no efficacy or safety comparison is made, and nothing here is dental, medical or pharmaceutical advice.
