Glucoside Foaming Cleanser

There are cleansers that promise to transform your skin, and then there are cleansers that promise to stop making things worse. The Ordinary Glucoside Foaming Cleanser belongs firmly in the second category, and that is not the backhanded compliment it might sound like.

When DECIEM launched this in late 2022, the brand already had the Squalane Cleanser — a balm-like oil cleanser beloved by the makeup-removing crowd. What they lacked was a straightforward water-based foaming cleanser for the second step of a double cleanse, or for those mornings when you just want to wash your face without thinking about it. The Glucoside Foaming Cleanser fills that gap with a formula so minimal it reads like a dare: water, two glucoside surfactants, a thickener, an antioxidant, a chelator, and two preservatives. That is the entire ingredient list. Eight ingredients. For context, most gentle cleansers on the market contain twenty to thirty.

The two surfactants — decyl glucoside and coco-glucoside — are derived from plant sugars and coconut oil. They are non-ionic, which in chemistry terms means they do not carry the electrical charge that makes sulfates so effective at stripping oil and, unfortunately, so effective at stripping the lipid barrier along with it. Glucoside surfactants clean through a gentler mechanism, dissolving sebum and environmental debris without the aggressive degreasing action. The Cosmetic Ingredient Review Expert Panel has assessed alkyl glucosides as safe and non-irritating in cosmetic use, and the foam they produce is lighter and airier than what sulfates deliver — which some users love and others find underwhelming.

The texture out of the tube is where this cleanser loses some people. It is a clear gel that can separate into a more watery consistency if the tube has been sitting for a while. A quick shake restores it, but the first encounter can be mildly off-putting. Once you work it between wet hands, it foams into a respectable lather — not the dense, creamy foam of a sulfate cleanser, but a genuine foam that feels like it is actually doing something. Rinse, and the skin feels clean, comfortable, and crucially, not tight. No squeaky feeling. No invisible film. Just skin that was dirty and is now clean.

The National Eczema Association Seal of Acceptance is the credential worth noting here. This is not a marketing badge you buy — it requires clinical validation that the product is suitable for eczema-prone skin, which means it passed testing for irritation potential on compromised barriers. For anyone who has cycled through supposedly gentle cleansers only to find their skin red and reactive by day three, that certification carries real weight.

What the cleanser does not do is equally important to understand. It will not remove waterproof mascara. It will not dissolve heavy-duty sunscreen. It is not a micellar water substitute, and it is not an oil cleanser. If you wear full makeup, this is your second cleanse, not your first. It also offers no treatment benefits — no salicylic acid for pores, no niacinamide for tone, no ceramides for barrier repair. The tocopherol provides minor antioxidant support, but in a rinse-off product with thirty seconds of skin contact, its contribution is marginal.

The absence of treatment ingredients is actually the point. A cleanser's primary job is to not damage the barrier while removing what needs to be removed. Every active ingredient added to a cleanser is an ingredient that may irritate during the brief contact window, and for sensitive or eczema-prone skin, that risk often outweighs the benefit. The Ordinary seems to understand this — they made a cleanser that washes things off and then gets out of the way, leaving the active ingredients to the serums and treatments that follow.

At 2.50 for 150 mL, the pricing is fair without being remarkable. It is cheaper than CeraVe's Hydrating Cleanser per milliliter and substantially cheaper than prescription-adjacent gentle cleansers, but it is not the dramatic value play that The Ordinary's treatment serums represent. A tube lasts two to three months with twice-daily use, which puts the annual cost around 0-75.

The sensory experience is, frankly, unremarkable — and for many users, that is the entire appeal. There is no fragrance to speak of, no tingle, no cooling sensation, no satisfying lather cascade. It is clinical in the best and most boring sense of the word. If you derive pleasure from your cleansing ritual, this will feel like washing your face with the concept of adequacy. If you derive relief from your cleansing ritual finally not causing problems, this is the product that understands the assignment.

The Ordinary Glucoside Foaming Cleanser is not trying to be your favorite product. It is trying to be the product you never have to think about — the reliable first step that your reactive, sensitive, or eczema-prone skin finally stops complaining about. And at eight ingredients, it has removed almost every possible reason for your skin to object.

Formula

The hero actives that drive this product's performance.

Ingredient	Function	Evidence
Decyl Glucoside	The primary surfactant in this eight-ingredient formula, derived from corn glucose and coconut oil. As a non-ionic cleanser, it generates stable foam without the charge-based disruption that sulfates inflict on the skin's lipid barrier. In this minimal formulation, it carries the full cleansing load alongside coco-glucoside, relying on gentle foaming action rather than stripping power.	well-established
Coco-Glucoside	A secondary plant-derived surfactant that amplifies the foam density and cleansing coverage of decyl glucoside without increasing irritation potential. Together, this glucoside pair creates a cleansing system that clinical testing shows preserves the skin barrier significantly better than sulfate-based alternatives.	well-established
Tocopherol (Vitamin E)	Serves as both a formula stabilizer and a brief antioxidant treatment during the cleansing step. In a rinse-off product, tocopherol's skin contact time is limited, but it provides mild photoprotective support and helps prevent oxidative degradation of the glucoside surfactants themselves.	well-established
Phytic Acid	A natural chelating agent that replaces synthetic EDTA in this formula, binding metal ions in water to maintain surfactant stability and cleansing performance. Also contributes mild antioxidant activity, making it a cleaner alternative to traditional chelators in this intentionally minimal formulation.	well-established

Evidence

The Science

The cleansing system in this product relies entirely on alkyl glucosides — a class of non-ionic surfactants synthesized from plant-derived fatty alcohols and glucose. Decyl glucoside and coco-glucoside differ in their alkyl chain length, which affects their foaming and cleansing characteristics. Decyl glucoside produces more abundant foam and handles the primary cleansing action, while coco-glucoside — with its mixed chain lengths from coconut oil — contributes foam stability and co-surfactant support.

The Cosmetic Ingredient Review Expert Panel published a comprehensive safety assessment of alkyl glucosides in the International Journal of Toxicology (2013), concluding that decyl glucoside and related compounds are safe as used in cosmetics when formulated to be nonirritating. The panel noted that glucoside hydrolases naturally present in human skin break these surfactants down into their constituent fatty acids and glucose — meaning the skin can metabolize them rather than simply enduring them.

The non-ionic nature of glucoside surfactants is the critical differentiator from sulfates. Anionic surfactants like sodium lauryl sulfate carry a negative charge that binds strongly to proteins in the stratum corneum, disrupting the lipid bilayers and causing transepidermal water loss. Non-ionic surfactants interact primarily through hydrophobic interactions, which are weaker and less destructive to the barrier. Clinical comparisons have demonstrated that glucoside-based cleansers produce significantly less irritation and lower TEWL increases than SLS-based formulations at comparable concentrations.

The pH of 5.0-6.0 is another deliberate formulation choice. The skin's acid mantle sits around pH 5.5, and alkaline cleansers (pH 9-10, common in bar soaps) temporarily raise skin pH, disrupting enzyme function and barrier recovery. By matching the cleanser's pH to the skin's natural range, this formula avoids the post-wash pH disruption that contributes to tightness and irritation.

Dermatologist Perspective

Dermatologists frequently emphasize that the cleanser step is where most routines go wrong — an overly harsh cleanser can undo the benefits of every product that follows. Board-certified dermatologists note that non-ionic surfactants like decyl glucoside represent the gentlest class of foaming agents available, and the National Eczema Association certification confirms this product meets clinical standards for compromised skin. Dermatologists commonly recommend glucoside-based cleansers for patients with atopic dermatitis, contact dermatitis, or post-procedure skin, where any barrier disruption during cleansing can delay healing. The minimal ingredient list also simplifies patch testing and allergen identification for patients working through elimination protocols.

Guidance

How to Use

Shake the tube gently before use to restore gel consistency. Dispense a coin-sized amount onto wet hands, work into a lather, and massage onto wet face for 30-60 seconds using gentle circular motions. Rinse thoroughly with lukewarm water and pat dry. For double cleansing, use after an oil-based cleanser to remove any remaining residue. Can be used morning and evening. Avoid the immediate eye area — while gentle, it can still sting if it enters the eyes.

Value Assessment

At 2.50 for 150 mL, this cleanser is priced competitively within the gentle cleanser category. It is less expensive per milliliter than many pharmacy-brand gentle cleansers and substantially cheaper than dermatologist-dispensed options. The value proposition is straightforward: you are paying for a well-formulated, clinically validated gentle cleanser with no frills. It does not offer the multitasking benefits of treatment cleansers, but for skin that needs simplicity, the cost of avoiding irritation from a more complex formula is itself the value.

Who Should Buy

Anyone with sensitive, reactive, or eczema-prone skin who has struggled to find a foaming cleanser that does not cause tightness, redness, or irritation. Also excellent for minimalists who want the simplest possible cleanser with clinical validation and for those building elimination routines to identify skin triggers.

Who Should Skip

If you wear heavy makeup or waterproof sunscreen daily and want a single-step removal, this cleanser will frustrate you. Also not the right pick if you enjoy a rich sensory experience from your cleanser — there is no luxurious lather, no pleasant fragrance, and no treatment benefits beyond clean skin.

Background

The Ordinary launched this cleanser in late 2022 to fill a gap in their lineup — despite being famous for treatment products, the brand had limited cleanser options. The formulation philosophy matches The Ordinary's ethos of transparency and simplicity: use only what's necessary, nothing more. The eight-ingredient formula is designed to do one thing — cleanse gently — and prove that a good cleanser does not need twenty ingredients to be effective.

About The Ordinary Established Brand (5–20 years)

The Ordinary launched under DECIEM in 2016 and rapidly became the most disruptive force in skincare by offering clinical-grade actives at unprecedented price points. Now owned by Estée Lauder Companies, the brand has built nearly a decade of consumer trust through ingredient transparency and accessible pricing.

Myth vs. Reality

Myth

Foaming cleansers are always harsh and stripping

Reality

This cleanser foams using glucoside surfactants derived from plant sugars, which are non-ionic and do not disrupt the skin's lipid barrier the way anionic sulfates can. The CIR Expert Panel concluded that alkyl glucosides are safe and non-irritating when properly formulated, and clinical testing of this specific product showed 97% of subjects felt it spread smoothly without discomfort.

Myth

A cleanser with only 8 ingredients can't clean effectively

Reality

Cleansing is about surfactant quality, not ingredient count. Decyl glucoside and coco-glucoside together provide effective removal of sebum, environmental debris, and non-waterproof products. The minimal formula simply means there are no unnecessary fillers — the surfactants do the work.
