Cosmetic manufacturing glossary

Cosmetic chemist

Also: formulation chemist, cosmetic formulator

A cosmetic chemist is a scientist who develops the formulas behind skincare, haircare, color cosmetics, and personal-care products. They select and balance ingredients for performance, stability, safety, and regulatory compliance, then translate a product concept into a manufacturable recipe. Brands hire cosmetic chemists to create new formulas or refine existing ones.

Cosmetic formulation

Cosmetic formulation is the process of combining active ingredients, bases, emulsifiers, preservatives, and additives into a finished cosmetic product. A formulation defines exact ingredients and percentages so the product is stable, effective, and safe to use. It is the technical blueprint a lab follows to manufacture the product.

Custom formulation

Custom formulation is the development of a brand-new, proprietary formula made specifically for one brand, rather than buying an existing stock formula. It lets a brand control the exact ingredients, claims, texture, and performance of its product, and the resulting formula is typically owned or licensed by that brand. It usually costs more and takes longer than a stock or private-label formula.

Contract manufacturer

Also: CMO, contract manufacturing organization

A contract manufacturer is a company that produces finished products on behalf of another brand. In cosmetics, a contract manufacturer mixes, fills, and packages products to a brand's formula and specifications, so the brand does not need its own factory. They are also called CMOs (contract manufacturing organizations).

Private label

Private label means selling a manufacturer's existing product under your own brand name and packaging. The formula is typically pre-developed and shared across multiple customers, so the brand customizes the label and packaging rather than the formula. It is the fastest, lowest-cost way to launch a product line.

White label

White label refers to a generic, ready-made product that any brand can rebrand and sell as its own. It is closely related to private label; the term emphasizes that the base product is unbranded and intended to be relabeled. White-label products let brands launch quickly without formulation work.

Minimum order quantity

Also: MOQ

Minimum order quantity (MOQ) is the smallest number of units a manufacturer will produce in a single run. MOQs exist because setup, sourcing, and cleaning costs make very small batches uneconomical. Lower MOQs make it easier for new or small brands to launch without large upfront inventory.

Stability testing

Stability testing checks that a cosmetic product stays safe, effective, and unchanged over its shelf life under normal and stressed conditions. Labs observe properties like color, scent, texture, pH, and microbial safety over time, often using accelerated aging at elevated temperatures. Passing stability testing is a common prerequisite before a product is mass-produced and sold.

Good Manufacturing Practice

Also: GMP, cGMP

Good Manufacturing Practice (GMP) is a set of standards for producing products consistently and safely, covering facilities, equipment, hygiene, documentation, and quality control. GMP-compliant manufacturing reduces contamination and error and is widely expected of reputable cosmetic manufacturers. Many retailers and markets require GMP-made products.

Cosmetic regulatory compliance

Cosmetic regulatory compliance means meeting the laws that govern how cosmetics are formulated, tested, labeled, and marketed in each market where they are sold. Rules differ by region and cover allowed ingredients, safety substantiation, claims, and labeling. Responsibility for compliance generally rests with the brand bringing the product to market.

Turnkey manufacturing

Turnkey manufacturing is a full-service model where one partner handles everything needed to deliver a finished, ready-to-sell product — formulation, sourcing, production, filling, and packaging. The brand provides the concept and requirements and receives finished goods, with fewer vendors to coordinate. It trades some control for speed and simplicity.

Escrow

Escrow is a payment arrangement where a neutral third party holds a buyer's funds and releases them to the seller only when agreed conditions are met. In manufacturing engagements it protects both sides: the maker knows funds exist before starting work, and the buyer knows payment is released against delivery. AJ Cosmo Labs uses escrowed payments to secure engagements between brands and the chemists and labs they hire.

NDA / CDA

Also: non-disclosure agreement, confidentiality agreement

A non-disclosure agreement (NDA), also called a confidentiality agreement (CDA), is a contract in which parties agree to keep shared information secret. In product development, NDAs protect formulas, ingredient lists, business plans, and other trade secrets exchanged between a brand and a chemist, lab, or manufacturer. Signing an NDA before sharing sensitive details is standard practice.

IP licensing of formulas

IP licensing of formulas is an arrangement where the owner of a cosmetic formula grants another party the right to use or sell it under defined terms, while retaining ownership. This lets a chemist or lab monetize a proprietary formula across multiple brands, or lets a brand use a formula without buying it outright. License terms set scope, exclusivity, duration, and royalties.

Household & cleaning product formulation

Also: cleaning product formulation, detergent formulation

Household and cleaning product formulation is the development of cleaners, detergents, soaps, and surface-care products by balancing surfactants, solvents, builders, fragrances, and preservatives. Formulators tune the surfactant system, pH, foam, and dilution so the product cleans effectively while staying stable and safe to handle. Finished formulas must also meet the labeling and safety rules of the markets where they are sold.

Candle formulation

Also: candle making, wax formulation

Candle formulation is the process of matching a wax base, fragrance oil, wick, and any dyes so a candle burns cleanly and throws scent as intended. Makers balance fragrance load, pour temperature, and cure time against the chosen wax and wick to control burn quality and scent strength. The goal is a repeatable recipe a manufacturer can produce at scale.

Food & beverage product development

Also: food formulation, beverage formulation

Food and beverage product development is the creation of consumable recipes by balancing ingredients, flavor, texture, nutrition, and shelf stability. Developers account for factors such as preservation method, water activity, allergens, and serving size so the product is safe, consistent, and compliant. The result is a documented formula and process a co-packer or manufacturer can scale.

Nutraceutical & supplement formulation

Also: supplement formulation, nutraceutical formulation, dietary supplement formulation

Supplement formulation is the development of dietary supplements — capsules, tablets, powders, gummies, and liquids — by setting active-ingredient dosages, delivery format, and excipients. Formulators balance potency, stability, and manufacturability while keeping claims and labeling within the rules for the market. Contract manufacturers then produce the supplement to that specification, often under Good Manufacturing Practice.

Paint, coating & ink formulation

Also: paint formulation, coating formulation, ink formulation

Paint, coating, and ink formulation is the development of liquid or powder finishes by balancing binders, pigments, solvents, and additives for the desired color, durability, and application properties. Formulators tune viscosity, drying or curing behavior, adhesion, and finish to suit the surface and use. Finished formulas must meet safety and environmental rules, such as limits on volatile organic compounds in some markets.

Agricultural product formulation

Also: agricultural formulation, crop input formulation

Agricultural product formulation is the development of inputs such as fertilizers, soil amendments, and crop-care products by combining active and carrier ingredients into a stable, applicable form. Formulators consider concentration, delivery format, stability, and handling so the product performs in the field. These products are heavily regulated, and approval and labeling requirements vary widely by region.

Aromatherapy formulation

Also: essential oil blending, aromatherapy blends

Aromatherapy formulation is the blending of essential oils and carriers into products such as roll-ons, diffuser blends, and topical oils. Formulators balance individual oils for scent profile and dilution, keeping topical products within safe usage levels. As with cosmetics, claims and labeling for these products are regulated depending on how they are marketed.

Fragrance formulation

Also: perfumery, perfume formulation

Fragrance formulation, or perfumery, is the craft of combining aroma materials into a balanced scent with top, middle, and base notes. Perfumers build an accord from natural and synthetic materials, then set the concentration for the intended product, such as an eau de parfum or a scented base. The finished fragrance is documented as a formula that can be reproduced and scaled.

Pet care product formulation

Also: pet product formulation, pet grooming formulation

Pet care product formulation is the development of grooming and care products for animals — shampoos, conditioners, sprays, wipes, and supplements — using ingredients chosen for animal safety and the target species. Formulators adjust pH, mildness, and actives differently than for human products, since animals tolerate and metabolize ingredients differently. Labeling and permitted claims are regulated and depend on the product type and market.

Co-packer

Also: contract packager, co-manufacturer

A co-packer, or contract packager, is a company that produces and packages products on behalf of a brand, most commonly in food, beverage, supplement, and household categories. Like a contract manufacturer, a co-packer lets a brand scale production without owning a facility, handling mixing, filling, and packaging to the brand's specification. The terms co-packer and contract manufacturer overlap and are often used interchangeably.

Batch / pilot batch

Also: production batch, pilot batch, scale-up batch

A batch is a single production run of a product made together under the same conditions and assigned one lot number for traceability. A pilot batch is a small trial run made before full-scale production to confirm the formula and process work outside the lab. Brands typically approve a pilot batch before committing to a larger manufacturing run.

Lead time

Lead time is the total time from placing an order to receiving finished goods, covering sourcing, production, filling, packaging, and quality checks. In cosmetics and CPG it is driven by component availability, batch scheduling, and testing, so it varies widely by product and supplier. Knowing lead time is essential for planning launches, restocks, and inventory.

Tech pack / product brief

Also: product brief, product specification, spec sheet

A tech pack, or product brief, is a document that captures everything a manufacturer needs to make a product: target formula or benchmark, claims, packaging, fill size, quantities, budget, and timeline. It gives the brand and the lab a shared specification so quotes and samples match expectations. A clear brief reduces back-and-forth and costly remakes.

Sampling & prototyping

Also: prototyping, lab samples, bench samples

Sampling and prototyping is the stage where a lab produces small bench samples of a formula so the brand can evaluate texture, scent, color, and performance before production. Several rounds are common, with each revision refining the formula toward the brand's target. Approved samples become the standard the final batch is matched against.

Fill & finish

Also: filling and packaging, fill finish pack

Fill and finish is the stage of manufacturing where bulk product is dispensed into its primary packaging, then sealed, labeled, and made ready for sale. It covers filling, capping, labeling, and secondary packaging such as cartons. A manufacturer may make the bulk formula, handle only fill and finish for a brand's existing bulk, or do both.

Bill of materials

Also: BOM

A bill of materials (BOM) is the itemized list of every component that goes into a finished product, including the formula ingredients and all packaging parts such as bottles, pumps, caps, labels, and cartons. Each line typically notes the part, supplier, and quantity per unit. The BOM is the basis for costing a product and ensuring nothing is missing before a production run.

Certificate of Analysis

Also: COA

A Certificate of Analysis (COA) is a document from a supplier or lab confirming that a batch of raw material or finished product meets its specified standards. It lists tested properties — such as identity, purity, pH, or microbial limits — and the results for that specific lot. COAs are used to verify quality and maintain traceability through the supply chain.

Safety Data Sheet

Also: SDS, MSDS, material safety data sheet

A Safety Data Sheet (SDS) is a standardized document describing the hazards, safe handling, storage, and emergency measures for a chemical or product. Suppliers provide an SDS for raw materials, and finished products may require one depending on their contents and market. SDSs support worker safety, shipping compliance, and regulatory record-keeping.

Preservative challenge testing

Also: challenge testing, PET, preservative efficacy test, microbial testing

Preservative challenge testing, also called a preservative efficacy test (PET), deliberately introduces microorganisms into a product to confirm its preservative system keeps it safe over its shelf life. The lab measures how effectively the formula kills or suppresses bacteria, yeast, and mold over time. Passing challenge testing is a standard safety requirement for water-containing cosmetics before they go to market.

Cruelty-free & vegan claims

Also: cruelty-free, vegan cosmetics, not tested on animals

Cruelty-free means a product and its ingredients were not tested on animals, while vegan means it contains no animal-derived ingredients; a product can be one without being the other. These are marketing claims, so brands must be able to substantiate them, often through supplier documentation or third-party certification. Permitted wording and proof requirements vary by market.

Drug vs. cosmetic

Also: OTC drug, OTC monograph, cosmetic vs drug

Whether a product is a cosmetic or a drug depends on its intended use and claims, not just its ingredients — products that treat or prevent a condition (like sunscreens, anti-acne, or anti-dandruff) are typically regulated as over-the-counter (OTC) drugs. OTC drug products face stricter rules for active ingredients, testing, manufacturing, and labeling, often under a monograph. Misclassifying a product or making drug claims on a cosmetic is a common compliance risk.

Componentry

Also: packaging components, primary packaging

Componentry refers to the physical packaging parts that hold and dispense a product — bottles, jars, tubes, pumps, caps, droppers, and closures. Choice of componentry affects cost, fill compatibility, stability, and the look and feel of the product on shelf. Component sourcing and lead times often drive a launch timeline as much as the formula does.

Landed cost

Also: unit economics, cost of goods, COGS

Landed cost is the all-in cost of one finished unit once everything is accounted for — formula, packaging, manufacturing, testing, freight, duties, and handling. It is the foundation of unit economics, since margin is the gap between landed cost and selling price. Brands calculate landed cost early to confirm a product can be sold profitably at its target price.

Dropshipping vs. holding inventory

Also: dropshipping, inventory model

Dropshipping is a model where a brand sells products that a supplier ships directly to the customer, so the brand never holds stock; holding inventory means the brand buys and stores finished units to fulfill orders itself. Dropshipping lowers upfront cost and risk but offers less control over branding, quality, and margins. Most brands with custom or private-label formulas hold inventory because production runs have minimum order quantities.

INCI list

Also: INCI, International Nomenclature of Cosmetic Ingredients, ingredient list

An INCI list is the standardized ingredient declaration on a cosmetic, using International Nomenclature of Cosmetic Ingredients names so the same ingredient is labeled consistently worldwide. Ingredients are generally listed in descending order of concentration, with allowances for those under one percent and color additives. A correct INCI list is a core labeling requirement in most markets.
