Cosmetic aluminum packaging: the choice that changes everything

what if the best cosmetic packaging wasn't plastic or glass, but a metal we've all known since childhood? we're talking about aluminum cosmetic packaging — why it's the most logical choice for your bathroom, how it's recycled, and why we chose it at basic. for several of our flagship products.

each year, the global cosmetic industry produces over 120 billion units of packaging, predominantly plastic. most end up incinerated or in landfills because cosmetic plastics are difficult to sort (small sizes, mixed materials, product residues). in light of this, aluminum cosmetic packaging appears as a credible alternative: lightweight, airtight, infinitely recyclable, and — bonus — rather attractive in a bathroom.

in this guide, we debunk misconceptions, compare aluminum to plastic and glass without mincing words, and show you concretely how we use it at basic. for our refillable deodorants and zero-waste kits. the goal: for you to know exactly what you're buying — and what happens to it afterward.

why talk about aluminum cosmetic packaging now?

because the topic has never been more relevant. the new European packaging regulation (PPWR, adopted in 2024) imposes increasing recycling rates, the prohibition of certain single-use formats, and a refillability obligation for several categories — including cosmetics. in other words: refillability is no longer a marketing argument, it's a regulatory direction.

on the consumer side, demand is also shifting. according to the Nielsen Sustainability 2024 study, 73% of European cosmetic buyers say they want refillable or reusable packaging. in French-speaking Switzerland, returnable jars, solid soaps, and refillable deodorants have become common practices in just a few years.

and in this landscape, aluminum cosmetic packaging holds a special place: it's one of the few materials to combine robustness (unlike cardboard), lightness (unlike glass), complete airtightness (unlike kraft paper refills), and real recyclability. we'll explain why.

aluminum, an infinitely recyclable material (for real)

the phrase "infinitely recyclable" is so overused that it has lost its meaning. in the case of aluminum, it is literally true. unlike plastics that lose quality with each recycling cycle (this is called "downcycling"), aluminum retains 100% of its mechanical and chemical properties after remelting. a cosmetic container can become a can, then a bicycle part, then a container again, without any loss of quality.

a few figures to put things into perspective:

• 75% of all aluminum ever produced since 1888 is still in circulation today (source: International Aluminium Institute). The same cannot be said for plastic.
• recycling aluminum requires 95% less energy than its primary production (from bauxite). in other words: every recycled can or casing saves the energy equivalent of a light bulb burning for 3 hours.
• in Switzerland, the recycling rate for aluminum exceeds 90% thanks to the IGORA collection system. this is one of the best rates in the world.

in simple terms: when you throw an aluminum cosmetic package into the dedicated bin (or return it to a store that accepts sorting), you know it will be remelted and put back into circulation. this is neither hope nor greenwashing; it is materials engineering that has worked for 130 years.

aluminum vs. plastic vs. glass: the unfiltered comparison

we are often asked: "why not glass? why not recycled plastic?" the answer lies in three criteria: carbon impact over the entire life cycle, real recyclability (not just theoretical), and daily use.

weight and transport

a 50 ml glass cosmetic jar weighs an average of 80 to 120 grams. the same format in aluminum: 15 to 25 grams. on a cargo ship crossing Europe with 20,000 units, the difference is measured in tons of fuel. transport accounts for 10 to 15% of a cosmetic's carbon footprint — lightweight packaging really makes a difference.

actual recyclability

cosmetic plastic poses a major problem: small formats (less than 5 cm) often fall through the sieves of sorting centers and end up in incineration. multi-layer materials (pumps, caps, films) further complicate matters. according to ADEME, only 26% of plastic cosmetic packaging is actually recycled in France.

glass, on the other hand, is closed-loop recyclable — but only if it is genuinely sorted (many cosmetic glasses contain additives that complicate sorting). aluminum does not have this problem: it is magnetically separable from other streams and accepted everywhere.

user experience

a glass container looks beautiful on a shelf but breaks in a damp shower. a plastic bottle is lightweight but gives a "cheap" impression that doesn't do justice to a natural product. aluminum offers a rare compromise: premium feel, robustness, longevity. in the context of a refillable aluminum cosmetic packaging, this last point becomes decisive — you keep the container for years, you only replace the refill.

aluminum cosmetic packaging: what it concretely changes at basic.

at basic., we chose aluminum for our refillable products because it checked all the boxes we wanted to check: recyclable in Switzerland, lightweight, durable, manufactured in Europe, and aesthetically honest. we hide nothing behind unnecessary cardboard packaging.

our most telling example is my refillable deodorant — starter kit. the case is made of recyclable aluminum. you buy the kit once, then you only buy refills. in 3 years, you save the equivalent of 9 classic plastic deodorant bottles, or about 180 grams of plastic avoided per person. multiplied by the thousands of basic. customers, we're talking about tons.

and the deodorant itself, the classik, was specifically formulated to go into this format: creamy texture that applies without waste, total absence of aluminum salts (ironic in an aluminum container, we know — but that's precisely the point: we use aluminum where it is useful, never in the cosmetic formula itself). effective for 24 hours, bicarbonate-free option available for sensitive skin, natural fragrances based on essential oils.

other brands offer refillable deodorants — notably Lamazuna, a French pioneer of the solid format in cardboard. their approach is excellent for those who accept the solid stick. we, however, chose the creamy texture in a metal case because it suits certain skin and underarm types better. both formats are complementary: the best cosmetic packaging is the one you actually use until the end.

to delve deeper into the topic of sustainable routines, we wrote a complete guide to the zero-waste bathroom that details how to replace each plastic product with a refillable, solid, or compostable alternative — step by step, without guilt.

false friends and real pitfalls: what to check before buying

not all aluminum cosmetic packaging is created equal. here are the points to look for on a product before pulling out your card:

• is the "refillable" claim real? some products present themselves as refillable but sell a disposable "kit." true refillability means you only buy the cosmetic part, not the whole system.
• the interior coating. bare aluminum can react with certain acidic active ingredients. good cosmetic containers have a thin inner layer of food-grade resin (BPA-free) to protect the formula. this layer does not prevent recycling, but it ensures product stability.
• the manufacturing origin. an aluminum cosmetic packaging manufactured in Europe (Italy, Germany, France) has a significantly lower carbon footprint than an Asian equivalent. at basic., we work with an Italian supplier, and this is information we publicly stand by.
• the size. the larger the container, the better the product/packaging ratio. a 100 ml jar has proportionally less packaging material per gram of cosmetic than a 15 ml jar. when possible, we favor large refillable formats.
• the ultimate: single-material. the best of the best is a 100% aluminum container (including the lid). as soon as a plastic cap is introduced, recyclability becomes more complex — not impossible, but it needs to be separated before disposal.

FAQ: everything you're wondering about aluminum cosmetic packaging

can aluminum in a cosmetic migrate into the product and be absorbed by the skin?

no, not if the container has an appropriate interior coating (which is the norm in the European industry). aluminum migration from the container to the formula is below the detection threshold in almost all tested products. note: this is different from aluminum salts voluntarily added to some antiperspirants, which are specifically formulated to interact with the skin. at basic., our deodorants are 100% aluminum salt-free, precisely for this reason.

how do I recycle my aluminum cosmetic packaging in Switzerland?

the easiest way: you take it to an IGORA collection point (specific bins in most municipal waste disposal centers and many large supermarkets). if your container has a plastic cap, separate it before discarding. rinse quickly to remove residues — no need to make it shine, just remove the bulk. the aluminum will be remelted and put back into circulation within a few months.

why aren't all cosmetics in aluminum if it's so good?

three reasons: cost (raw aluminum costs 3 to 5 times more than standard plastic), industrial complexity (filling lines are different and less common), and brand habits. switching to metal requires a real investment and a desire for long-term commitment. many prefer recycled plastic or "lightweight" glass as a compromise.

is aluminum more ecological than returnable glass?

it depends on the circuit. a local returnable system (jar reused 30 times in a short circuit) beats almost everything. but as soon as you step out of an ultra-local circuit, the weight of glass and the energy required for washing/transport tip the scale in favor of refillable aluminum. for a product sold throughout French-speaking Switzerland or beyond, aluminum is generally the best compromise.

and what about printing inks on aluminum, do they pose a recycling problem?

no. during high-temperature remelting (660°C and above), surface inks and varnishes are burned off and do not contaminate the metal. this is one of the reasons why aluminum is so easy to recycle: no matter what's on it, remelting sorts it out.

does basic. use recycled aluminum or new aluminum?

our containers are made from aluminum containing a minimum of 30% post-consumer recycled material, with a target of 50% by 2027. 100% recycled for food/cosmetic use remains technically demanding (purity tolerances), but the industry is progressing rapidly.

what if I lose the lid or it breaks, do I have to throw away the whole container?

no, contact our customer service. we can send you a replacement part rather than having you buy a complete kit. this is the very logic of refillable products: extending the life of the system, not prematurely recycling it.

so, should we switch to aluminum cosmetic packaging?

if you had to remember one thing: a good cosmetic package is not one that says "eco-friendly" on the label; it's one that is truly recyclable in your country, lasts a long time, and allows you to refill the product without buying everything again. aluminum cosmetic packaging ticks these three boxes better than most alternatives — provided it is well-designed, manufactured locally, and supported by a real refill system.

at basic., we don't claim to have invented the concept. we adopted it because it's consistent with what we've advocated from the beginning: simple, natural cosmetics, made in Switzerland, with as little waste as possible. if you want to try it, start with my refillable deodorant — starter kit. you keep the case, you just buy the refills. that's it.
