The brand on your moisturizer’s label probably did not make it. In most cases, a specialist factory called a contract manufacturer (CM) turned the brand’s concept into a formula, bought its 20 to 35 ingredients from suppliers around the world, blended them in a stainless-steel mixing kettle, filled the jars, and shipped the finished cases — while the brand handled the concept, the testing claims, and the marketing. This arrangement is normal, legal, and usually good for quality. It also hides an entire supply chain, and a great deal of the industry’s waste, from the person holding the jar.
Who actually makes your moisturizer?
Walk the aisles of any beauty retailer and you are looking at the output of specialist factories most shoppers have never heard of. These contract manufacturers produce finished goods for brands large and small — from the indie serum brand founded on Instagram to, for parts of their ranges, some of the biggest names in the store.
Industry data consistently indicates that a majority of beauty and personal-care brands outsource at least part of their production, and for young brands the share is higher still, because building a factory before you have proven demand makes no financial sense. The scale is easiest to see in dollars: market analysts valued global cosmetics contract manufacturing at roughly $17.8 billion in 2023, heading toward about $22 billion by 2028 — and that figure counts only the manufacturing fees, not the retail value of everything those factories produce.
None of this is a scandal. It is specialization. A good CM runs chemistry labs, regulatory teams, and filling lines that no single young brand could afford, and spreads that capability across dozens of customers. Your label may hint at the arrangement in small print: “distributed by” or “manufactured for” instead of “manufactured by.”
What happens between a formula and your shelf?
Every jar takes roughly the same journey, whoever makes it. The table below maps the steps, who typically performs each one, and — the part this series cares about — where leftover material piles up along the way.
| Journey step | Who usually does it | Where surplus is created |
|---|---|---|
| Brief and formulation | Brand plus the CM’s chemists | Lab-scale only: sample bottles, pilot batches |
| Ingredient sourcing | The CM’s purchasing team | The big one: minimums force buying far more of an ingredient than the production run needs |
| Compounding (batching) | The CM’s production floor | Kettle heels, off-spec batches, partial drums returned to the rack |
| Filling and packaging | The CM, or a dedicated filler | Component overruns, line-start scrap, short-filled units |
| Distribution and retail | Brand, distributors, retailers | Unsold finished goods, expired stock, returns |
Step one is the recipe. A moisturizer is an emulsion — oil and water persuaded to coexist — and a typical formula lists somewhere between 15 and 35 ingredients, a range we documented from real labels in How Many Ingredients Are in a Typical Skincare Product?
Step two is the invisible one. Every ingredient on that list is a separate raw material with its own supplier, price, lead time, and paperwork. The purchasing team buys each one individually, in the containers the industry actually ships: drums of roughly 200 kg for liquids, cartons of 20–25 kg for powders, pails of 18–20 kg in between. A 25-ingredient moisturizer can mean 20 or more separate purchase orders before the first batch runs.
Step three is compounding. Ingredients are weighed out, heated, mixed, and cooled in kettles that hold anywhere from a few hundred kilograms to several tonnes per batch. Quality checks happen here — viscosity, pH, microbial testing — before anything moves on.
Steps four and five are the parts consumers can picture: filling machines dose the cream into jars, cartoning lines box them, and pallets leave for distribution centers and store shelves.
Where does the waste actually happen?
Some waste is visible and well-known: unsold finished products, damaged packaging, expired stock at retail. But the step with the least visibility — ingredient sourcing — is where surplus is built into the system by simple arithmetic.
Suppliers sell raw materials with a minimum order quantity (MOQ), and the minimum is set by the container, not by the buyer’s recipe. Say a formula uses a botanical extract at 1 percent and the batch is 800 kg: the run needs 8 kg. If the supplier’s minimum is one 200 kg drum, the purchase order is for 200 kg, and 192 kg go onto a warehouse rack the day the drum arrives. Suppliers are not being greedy here — repackaging small quantities has real costs in labor, testing, and contamination risk. We walked through the full economics in The Hidden Cost of MOQs.
Multiply that mismatch across a 25-line ingredient list, then across every formula the factory runs, and the result is shelves of part-used drums and unopened cartons, each with a shelf life quietly ticking down. Nobody at the factory is paid to find those leftovers a second home, so the knowledge of what is sitting there rarely leaves the building — a dynamic we examined in Why Surplus Raw-Material Listings Go Stale. Industry data suggests much of this material eventually ages past its retest date and is written off and disposed of, not because it was bad, but because no buyer ever knew it existed.
The manufacturers holding this surplus are not villains. They are doing exactly what the economics of minimums and production schedules force them to do. The waste is structural, which is precisely why it persists.
Why does packaging get all the sustainability attention?
Because packaging is the part you can hold. When a shopper thinks about beauty and the environment, they think about the jar, the pump, and the box — reasonably, since the industry produces an estimated 120 billion units of packaging a year, and reporting suggests only about 9 percent of it is recycled. Brands respond to what customers can see, so refill pouches and recycled-plastic jars dominate the sustainability conversation.
The drum of surplus emollient aging in a warehouse three suppliers upstream has no such constituency. No consumer ever sees it, no label discloses it, and no recycling logo addresses it. That does not tell us which problem is bigger — comparing the footprint of packaging with the footprint of wasted ingredients deserves its own careful treatment, and it will get one in a future post. For now, the point is simpler: the sustainability story consumers hear ends at the jar.
Common questions
Is it bad that brands don’t make their own products?
No. Specialization is how most manufactured goods are made — few electronics brands build their own phones either. A capable CM brings formulation chemists, regulatory expertise, and quality systems most brands could never justify building in-house, so outsourcing often raises quality rather than lowering it. What matters is whether the brand chooses its partner carefully and stands behind the product, not who owns the kettles.
Does the same factory make both luxury and drugstore products?
Sometimes, yes. A single CM may fill a prestige cream and a mass-market lotion on the same lines in the same week. That does not mean the products are identical — formulas, ingredient grades, and specifications differ — but the machinery and the people are often shared.
How can I tell who made my product?
Usually you can’t. Most labels name only the brand, sometimes with “distributed by” or “manufactured for” language that signals a third party made it. Manufacturing agreements are typically confidential — the norm across the industry, not a red flag.
Does outsourced manufacturing make products less safe?
The same cosmetic regulations apply no matter who does the manufacturing, and reputable factories operate under documented good manufacturing practices with batch records, testing, and traceability. A brand outsourcing to an experienced CM often gets stronger quality control than it could run itself.
