What's Actually In Your Lube?

Let's be honest: lube doesn't get nearly enough airtime. It's shoved behind the pharmacy counter, bought with the same shifty energy as a hangover snack, and rarely discussed openly - even though it's one of the most useful, body-positive products you can own. Whether you're dealing with vaginal dryness, navigating sex after childbirth, easing into menopause, or simply want a more comfortable, pleasurable experience, lubricant is your best friend. We firmly believe it should be in everyone's bedside drawer (right next to the HANX condoms, naturally).

But we get it. With so much noise online about "toxic" ingredients and mystery formulas, it can feel impossible to know what you're actually putting near your most sensitive bits. So, we thought: why not just tell you exactly what's in ours?

Here's everything you need to know about the HANX water-based lubricant- ingredient by ingredient, myth by myth.

First Things First: Why Water-Based?

Not all lubricants are created equal. There are oil-based, silicone-based, and water-based formulas; and each has its place. But water-based lube is widely considered the gold standard for everyday intimate use, and here's why:

• It's condom-compatible. Oil-based lubes can degrade latex condoms (not ideal). Water-based? Totally safe with all condom types, including HANX natural latex condoms.

• It's kind to your vaginal microbiome. A well-formulated water-based lube works with your body, not against it.

• It's versatile. Safe for use with sex toys, during penetrative sex, solo play, or simply to combat dryness day-to-day.

• It cleans up easily. Because, well, it's water-based.

What's Inside the Bottle?

Let's get into it. We know "Hydroxyethylcellulose" and "Potassium Sorbate" sound like they belong in a chemistry lab rather than a lube bottle, so we've asked our in-house gynaecology expert, and HANX co-founder, Dr Sarah to translate. Think of this as your ingredient cheat sheet.

Aqua (>75%)

Yes, the main ingredient is water. More than three quarters of this formula is pure aqueous base, which is exactly what you want. The high water content is what makes it feel natural, light, and comfortable. Your vagina is a fan.

Propylene Glycol (>10% – ≤25%)

This one can sometimes get a bad rap, mostly from people who've never actually looked at the science. Propylene Glycol is a humectant - it attracts moisture and holds it where you need it most. It's reviewed and accepted as safe at this concentration by the Scientific Committee on Consumer Safety (SCCS), approved as a food additive by the European Food Safety Authority, and routinely used as a pharmaceutical excipient in vaginal drug products. Yes, it can be derived from petroleum (so can lots of things), but origin has nothing to do with safety. A very small subset of people may notice sensitivity to it, as with any ingredient, and if you're in that camp, it's worth knowing. But for the vast majority? It's a well-tolerated, well-established ingredient doing exactly what it's supposed to do.

Hydroxyethylcellulose (>1% – ≤5%)

This is the ingredient that gives the lube its texture- the satisfying, gel-like consistency that actually stays where you want it. It's an inert, non-ionic polymer (fancy way of saying: very well-behaved, no funny business) with no known sensitisation potential. It's so gentle, in fact, that it's used in WHO-referenced lubricant placebo formulations and in pharmaceutical vaginal delivery systems. Any claims about it disrupting the vaginal microbiome? Not backed by a single credible scientific source.

Sodium Benzoate & Potassium Sorbate (>0.1% – ≤1% each)

These two are the formula's preservatives, and they're present because a water-based product without preservatives is a breeding ground for bacteria and mold. That is a far greater risk to your intimate health than a sub-1% preservative. Both are permitted under EU Cosmetics Regulation (Annex V), both are approved food additives (E211 and E202 respectively), and both are among the most widely used and well-tolerated preservatives in food and personal care worldwide. The "in vitro cytotoxicity" concerns you might have read about online? Those apply to vastly higher concentrations than what's present here. Context matters.

Sodium Acetate & Citric Acid (≤0.1% each)

Here's where it gets really clever. These two ingredients work together as a pH buffer- they keep the formula sitting in a mildly acidic, physiologically appropriate range that mirrors the healthy vaginal environment. A stable, slightly acidic pH is actually protective of the vaginal microbiome, not disruptive to it. Citric acid, by the way, is naturally produced by the human body and approved without restriction as a food additive (E330). At less than 0.1%, its presence is entirely functional and totally unremarkable.

Isopropyl Alcohol (≤0.1%)

Present at trace levels - less than one tenth of one percent. When people worry about isopropyl alcohol in formulations, they're thinking of concentrated, undiluted IPA (the 60–70% stuff used in hand sanitiser). At ≤0.1% in an aqueous formula, there is no meaningful drying or irritancy risk whatsoever. It's there as a processing aid, doing a quiet, unglamorous job at a vanishingly small concentration.

Cellulose (≤0.1%)

Plant-derived, inert, and completely unremarkable. An extremely small amount of cellulose, a structural polymer found in every plant on earth, poses no known irritancy risk or microbiome concern at any concentration. 

Sodium Hydroxide (≤0.1%)

The words "sodium hydroxide" (a.k.a. caustic soda) can feel alarming. And we understand why. But here's the thing: this ingredient is present at trace levels as a pH adjuster, and it does not exist as free caustic soda in the finished product. During formulation, it reacts with the acidic buffer components and is fully neutralised. It's listed on the INCI ingredient list because EU regulations require full ingredient transparency, not because the finished product is in any way corrosive. We love a transparent label, but this one requires a bit of context.

A Word From Our Co-founder

"As a gynaecology doctor, I recommend water-based lubricant regularly - to patients of all ages, from those in their twenties navigating dryness related to hormonal contraception, to those going through perimenopause and beyond. The HANX lubricant formulation has been carefully developed to sit within a physiologically appropriate pH range, making it genuinely compatible with vaginal health. Every ingredient is present at a concentration that is fully compliant with EU cosmetic safety regulations, and none of them give me any clinical concern. Equally important is what's not in it: the formula is free from glycerine, parabens, spermicides, anaesthetics, tingling gels, and added flavours - all of which can disrupt the vaginal microbiome or cause irritation to delicate genital tissue. These are ingredients I actively advise patients to avoid, so their absence here matters. The formulation is also fully compatible with latex condoms, which is a non-negotiable for me when recommending lubricants to patients who rely on condoms for contraception or STI prevention. This is a product I'm proud to stand behind."

— Dr Sarah, Doctor & HANX Co-Founder

Who Is HANX Lubricant For?

The short answer: everyone with a body! The slightly longer answer:

• People experiencing vaginal dryness - whether from hormonal contraception, perimenopause, menopause, stress, or simply on a given day.

• Anyone using condoms - it's fully latex-compatible and enhances comfort without compromising protection.

• Those returning to sex after childbirth - hormonal shifts can mean dryness lingers for months postpartum, and lube is genuinely one of the most recommended products in that space.

• People with sensitive skin - the formula has been developed with tolerability in mind.

• Anyone who just wants better, more comfortable sex. (That should be all of us!)

There's no age requirement, no minimum level of "need," and absolutely no shame involved. 

The Bottom Line

Every ingredient in the HANX water-based lubricant is there for a reason, at a concentration that is safe, well-evidenced, and compliant with EU regulation. The formula is over 75% water, pH-balanced to support vaginal health, free from any ingredients restricted for intimate use, and completely condom-compatible.

We believe you deserve to know exactly what you're using, and why. Because bodies are brilliant, and they deserve products made with the same care and transparency you'd expect from anything else you put in or on them.
