The aloe version of Honey, our personal lubricant, is labelled pH-balanced, and it's a phrase plenty of people look for when they choose a lube. It's printed on a lot of bottles, and it sounds like exactly the right thing for intimate skin.
The trouble is that the phrase can mean several things, and on its own it tells you less than you'd hope. This article explains what to look for on a lube label, including a second number most labels leave out, and what the World Health Organization advises. If you want the background on vaginal pH itself, our article on vaginal pH explained covers it, so we won't repeat it here.

The short answer
A pH-balanced lube is usually one made to sit close to the natural acidity of the vagina. That's a good thing to look for in a water-based lube used vaginally. It's only half the picture, though. How concentrated a lube is, called its osmolality, matters at least as much, and it's rarely on the label.
The most useful labels give numbers for both. When a label just says "pH-balanced", it's hard to know how close it really is, and that includes ours, which we explain below.
What pH-balanced can mean on a label
pH is a scale from 0 to 14 that measures how acidic or alkaline something is, with 7 as neutral. The healthy vagina is acidic. The WHO advisory note on lubricants, written with UNFPA and FHI360, says the pH of the healthy vagina is normally in the range 3.8 to 4.5, while the rectum is closer to neutral, around pH 7.
So "balanced" depends on what it's balanced to. A label might mean the lube matches the vagina, somewhere near 4 to 4.5, or that it's close to the pH of skin elsewhere on the body, which is less acidic.
It might also simply mean the lube isn't strongly alkaline. We're not aware of a rule that fixes which one a brand has to mean.
That's why a number beats a phrase. If a brand gives a pH value, you can compare it with the vaginal range yourself. If it doesn't, you can ask, and a brand that has tested its formula should be able to answer.
One more thing about pH on a label: it only applies to water-based lubes. A clinical review of lubricants and moisturizers points out that oil- and silicone-based lubricants do not have a pH or an osmolality value, as they contain no water. A silicone lube that says pH-balanced is using the phrase loosely.
What the WHO advises for pH
The WHO advisory note is written for agencies that buy lubricants in bulk for health programmes, but its reasoning applies to anyone choosing a lube. It explains that a high vaginal pH can raise the risk of bacterial vaginosis, and it sets out an ideal: a vaginal lubricant should have a pH of about 4.5 and a rectal lubricant of about 5.5 to 7.
It also admits something worth knowing: those two targets can't be met by a single lubricant, because the vagina is far more acidic than the rectum. The note's advice is to think about how a lube will mainly be used: for vaginal use, about 4.5 is preferable, and where the main use is anal or can't be known, 5.5 to 7 is more appropriate. As an outer limit for buying in bulk, it recommends a pH of 7 or less.
For you, that means a vaginal pH-balanced lube is the right fit for vaginal use, and it isn't automatically the best match for anal use. For our plugs, which say to use a water-based lubricant only, a water-based lube is still the right kind; just know that "pH-balanced" on a label usually refers to the vagina.
Osmolality, the number most labels leave out
Osmolality measures how much is dissolved in the water of a lube. Think of it as how concentrated the lube is. It's measured in milliosmoles per kilogram (mOsm/kg), and the body's own fluids sit in a narrow range. The WHO note gives 260 to 290 mOsm/kg for vaginal secretions.
Why it matters: the WHO note says that several papers suggest lubricants with high osmolality might damage the lining of the vagina and anus, mostly based on laboratory testing, and that this was confirmed for rectal use in a small study of 10 volunteers.
A laboratory study of over-the-counter lubricants found the same pattern in tissue samples: hyperosmolar lubricants demonstrated reduction of tissue viability and epithelial fracture/sloughing, while the nearly iso-osmolar and silicone-based lubricants showed no significant changes. This was lab tissue, not people, so it tells you about risk, not about what any one person will feel.
What the WHO advises for osmolality
The WHO's ideal is that a lubricant's osmolality should not exceed 380 mOsm/kg. Most commercial lubricants are far above that, between 2,000 and 6,000 mOsm/kg according to the note, so it recommends 1,200 mOsm/kg as a practical upper limit for now. The clinical review of lubricants and moisturizers cites the same two numbers, 380 as the ideal and 1,200 as the limit generally accepted in practice.
The main thing that raises osmolality is glycol, such as glycerin and propylene glycol. These are added to hold water and keep a lube moist, which is useful, but too much makes a lube very concentrated. To stay under 1,200, the WHO note advises no more than 9.9% glycerol, or 8.3% propylene glycol. That's why a lube with glycerin high on its ingredient list may be more concentrated than one without.
What to look for, in one table
Here's a short checklist for a water-based lube you'll use vaginally.
| What to check | What good looks like | Why it matters |
|---|---|---|
| pH, as a number | About 4.5 for vaginal use; 5.5 to 7 for anal use | Close to the body area it's used on |
| Osmolality, as a number | 380 mOsm/kg or less is ideal; under 1,200 is the WHO's practical limit | Very concentrated lubes can damage the lining in lab studies |
| Glycerin or glycols high on the list | Lower is better for osmolality | They're the main thing that raises it |
| Fragrance, flavour, warming | None, if your skin reacts | Common reasons intimate skin reacts |
| "pH-balanced" with no number | Ask the brand for the number | The phrase alone is hard to judge |
| Silicone lube | pH doesn't apply | It contains no water |
The same clinical review sums up what to aim for: a product that is optimally balanced in terms of both osmolality and pH, and is physiologically most similar to natural vaginal secretions.
Honey's aloe version, and what we can tell you
Honey's aloe version is made in Montréal and labelled water-based and pH-balanced. Its ingredients, as the page lists them: a base of water, propanediol, hydroxyethylcellulose and glycerin; aloe, oat, chamomile, calendula and green tea; tremella (a snow mushroom), gluconolactone and sodium hyaluronate (hyaluronic acid), which hold on to water; and sodium benzoate and potassium sorbate to preserve it. There's no fragrance, no parabens and no alcohol.
The Honey page says the aloe version is pH-balanced, but it doesn't list the exact pH or osmolality number. Having just written that a pH-balanced claim without a number is hard to judge, we'd rather say that plainly about our own bottle than leave it out.
On any lube label, ours included, these are the numbers to look for. For vaginal use, the WHO advisory note gives a pH of about 4.5 as the ideal, with the healthy vagina normally at 3.8 to 4.5. For osmolality, it gives 380 mOsm/kg or less as the ideal and 1,200 mOsm/kg as the practical upper limit.
The silicone version contains no water, so pH and osmolality don't apply to it. It's the one that stays slippery in the shower or bath, and it isn't recommended with silicone toys. Our comparison of the two kinds covers the rest of that choice.
The bottle is 4 oz (118 mL) with a flip cap for both versions, and both work with latex and polyisoprene condoms. The aloe version is $29 CAD ($22 USD), the silicone version $32 CAD ($24 USD), and you pick one on the Honey product page.
When pH is a question for a doctor
A lube's pH matters for comfort, but lube isn't a way to change or fix vaginal pH. If you notice a new or strong odour, a change in discharge, itching, or burning when you pee, see a doctor or nurse. Those can be signs of an infection that needs a diagnosis, and a lube isn't made for any of them.
The same goes for dryness that lasts. If sex is uncomfortable even with lube, or dryness bothers you most days, our article on dryness in perimenopause explains the options a doctor may suggest. And if any lube causes stinging or burning that lasts, rinse with plain water and stop using it. For the other kinds of lube and their ingredients, see our general guide to personal lubricants.
Frequently asked questions
What does pH-balanced lube mean?
It usually means the lube is made to sit close to the natural acidity of the vagina, which is normally pH 3.8 to 4.5. There's no single rule for the phrase, though, so it can also mean close to skin pH or simply not alkaline. A number on the label, or from the brand, is the only way to know.
What pH should a lube be?
The WHO advisory note on lubricants says a vaginal lubricant should ideally have a pH of about 4.5, and a rectal lubricant about 5.5 to 7. It notes that no single lube can meet both targets, so choose for how you'll mainly use it. Silicone lubes have no pH, because they contain no water.
What is osmolality in lube?
Osmolality measures how concentrated a lube is, meaning how much is dissolved in its water. Vaginal secretions sit around 260 to 290 mOsm/kg. The WHO's ideal is 380 or less, with 1,200 as a practical upper limit, because very concentrated lubes have damaged the lining of the vagina and rectum in laboratory studies.
Does glycerin in lube cause problems?
Glycerin itself is a common, useful humectant that helps a lube stay moist. The concern is the amount. Too much glycerin raises osmolality, and the WHO advises keeping it at 9.9% or less to stay under 1,200 mOsm/kg. If a lube stings, wash it off with water and switch to another one.
Is silicone lube pH-balanced?
Silicone lube has no pH at all, because pH only applies to things that contain water. That also means it has no osmolality. It's a different kind of product, chosen for long-lasting glide and water play. It isn't recommended with silicone toys, and it's harder to wash off than water-based lube.
Can lube change my vaginal pH?
Lube isn't a way to raise or lower vaginal pH on purpose, and a lube matched to the vagina is chosen so it doesn't push pH up. Our article on vaginal pH explains what does shift it. The WHO notes that a high vaginal pH can raise the risk of bacterial vaginosis, which is one reason it advises acidic lubes for vaginal use. New odour or discharge is a reason to see a doctor.
