Cosmetics Industry Terminology

Actives (Active Ingredient)

Ingredients delivering a primary functional benefit (e.g., brightening, moisturizing). In the U.S., the term “active ingredient” has a specific meaning for OTC drugs; in cosmetics it’s used colloquially.

This serum’s actives are niacinamide and peptides; Raise the active level from 2% to 4%; We need stability data for the active complex

Airless Packaging

Dispensing systems that protect formulas from air exposure and contamination, improving stability and product evacuation.

Switch to airless to reduce oxidation; Airless pumps improved product evacuation to 96%; Airless required a lower-viscosity fill

Allergens (Fragrance Allergens)

Label-relevant fragrance components (e.g., limonene, linalool) that may trigger sensitization; disclosure thresholds apply in the EU and likely in the U.S. under MoCRA.

List EU-designated allergens above threshold; MoCRA will require allergen labeling; Run an HRIPT due to allergen risk

Anhydrous Formulation

Water-free product systems (balms, oils, sticks). Lower water activity reduces microbial risk but doesn’t eliminate it if humectants are high.

An anhydrous stick doesn’t need traditional preservatives; Watch aw in high-glycerin balms; Anhydrous masks avoid microbial growth

Animal Testing / Cruelty-Free

Policies and regulations restricting animal testing of cosmetics; claims require verifying ingredient and finished-product practices across markets.

EU ban requires non-animal safety methods; China exemptions reduce animal tests for general cosmetics; Verify cruelty-free supplier declarations

Anti-Aging Claims

Marketing statements about skin appearance improvement. Must avoid drug claims (structure/function) in many jurisdictions and be substantiated.

Use ‘reduces the appearance of wrinkles’ not ‘treats wrinkles’; Substantiate firming claims with instrumental data; Avoid drug-like collagen synthesis claims

Batch Record

GMP documentation of each production lot: materials, equipment, parameters, in-process tests, deviations, and yields.

Record operator initials and step times; Investigate deviation in Batch 24-017; Yield fell 2% below target

Certificate of Analysis (COA)

Supplier document confirming a lot meets agreed specifications (identity, purity, assay, microbiology, etc.).

COA shows viscosity within spec; Reject the lot due to low assay; Attach COA to the PIF

Claims Substantiation

Evidence supporting marketing statements, ranging from in vitro and instrumental tests to clinical studies and consumer perception.

Run a 4-week clinical for hydration claim; Instrumental TEWL supports the barrier claim; Consumer perception supports ‘95% saw glow’

Clean Beauty

Positioning focused on safety, transparency, and environmental standards; not legally defined and varies by retailer/brand.

Retailer clean list bans certain silicones; Define our clean standard and whitelist; Audit ‘free‑from’ claims for compliance

CPNP (EU Cosmetic Product Notification Portal)

EU online portal where products must be notified pre-market by the Responsible Person under EC 1223/2009.

Notify the shade extensions on CPNP; Upload label artwork and category; Responsible Person submitted the CPNP

CPSR (Cosmetic Product Safety Report)

EU-required two-part safety assessment (Annex I): Part A (data) and Part B (safety conclusion) signed by a qualified assessor.

Toxicologist finalized the CPSR Part B; Include NOAEL and MoS calculations; CPSR cites ISO 22716 GMP

EU Cosmetics Regulation (EC No 1223/2009)

Core EU law governing cosmetic safety, labeling, notification, responsible person, and restricted/allowed substances.

Check Annex II for banned substances; Label per Article 19; Maintain a PIF under Article 11

Fill Weight / Net Contents

The legally required declaration of product quantity; must meet weights-and-measures tolerances (e-mark in EU where applicable).

Declare 50 mL e on pack; Adjust for evaporative losses at fill; QA verified net contents compliance

Fragrance (IFRA Compliance)

Ensuring fragrance usage levels and allergens comply with IFRA standards and regional labeling thresholds.

Obtain IFRA certificates for each fragrance; Limit fragrance at 0.4% per cat 5A; Allergen listing triggers at 0.001% leave-on

Free-From Claims

Statements about excluded ingredients; must be truthful, not misleading, and compliant with local guidance (e.g., EU common criteria).

‘Paraben-free’ must not disparage approved preservatives; Avoid ‘chemical-free’; Align free-from list with retailer policy

GMP (ISO 22716)

Good Manufacturing Practices guideline for cosmetics covering personnel, facilities, equipment, documentation, production, QC, and complaints.

Audit contract manufacturer against ISO 22716; Train staff on SOP revisions; Log all deviations and CAPAs

HLB (Hydrophilic-Lipophilic Balance)

A system to select emulsifier blends by matching the oil phase’s required HLB to achieve stable emulsions.

Calculate required HLB for the oil phase; Blend emulsifiers to hit HLB 10; HLB mismatch caused separation

Humectant

Water-attracting ingredients that increase skin hydration (e.g., glycerin, hyaluronic acid, propanediol).

Add 3% glycerin for moisture; Propanediol boosts slip and humectancy; Balance humectants to avoid tack

IFRA Standards

Fragrance industry safety standards that set use-level limits by product category to minimize sensitization/irritation.

We’re on IFRA Amendment 51; Check product category before dosing; Request IFRA certificates from supplier

INCI (International Nomenclature of Cosmetic Ingredients)

Standardized ingredient naming used on cosmetic labels globally (regional adaptations exist).

List ingredients by INCI names on label; Cross-check INCI for plant extract; Update INCI order after reformulation

In Vitro / In Vivo Testing

Non-animal test methods at cell/tissue level (in vitro) and human volunteer studies (in vivo) used for safety and efficacy evidence.

Use in vitro antioxidant assay first; Confirm in vivo moisturization with corneometry; In vivo SPF per ISO 24444

ISO 16128 (Natural Origin Index)

Framework defining natural/organic ingredient categories and indices; not a certification but a calculation method for content claims.

Compute natural origin index = 0.92; Classify surfactant as ‘derived natural’; Share ISO 16128 calculation with retailer

LCA (Life Cycle Assessment)

Methodology for quantifying environmental impacts across a product’s life (materials, manufacturing, transport, use, end-of-life).

Run LCA to compare jar materials; Hotspot is glass transport emissions; Set targets from the LCA results

Microbiological Limits

Register facilities by the deadline; List products with FDA; Maintain safety substantiation on file

NMPA (China) Registration

China’s regulatory process for cosmetics; general products often use filing, while special cosmetics (e.g., hair dye, sunscreen) require registration.

General cosmetics use simplified filing; Provide safety assessor’s report; Claim testing required for special cosmetics

OTC Drug vs Cosmetic (US)

Distinction based on intended use/claims; OTC categories include sunscreens, anti-acne, antiperspirants, dandruff, etc. Cosmetic claims must avoid drug language.

SPF is OTC under the monograph; Acne claims move us to OTC; Keep claims cosmetic to avoid OTC

PAO (Period After Opening)

Open-jar symbol indicating usable period after first opening (e.g., 6M, 12M), particularly in EU when shelf life exceeds 30 months.

Use 12M PAO for the cream; PAO not needed under 30 months shelf life?; Include PAO icon on label

Patch Test

Skin application test (e.g., HRIPT) to assess irritation/sensitization potential and support claims.

Conduct HRIPT for irritation/sensitization; 24-hour occlusive patch on forearm; Use patch data to support ‘dermatologist tested’

PET (Preservative Efficacy Test / Challenge Test)

Testing antimicrobial system performance by inoculating microbes and measuring log reductions over time; often via ISO 11930.

Run ISO 11930 challenge test; System A failed at 0.5%; Reformulate to pass PET criteria

PIF (Product Information File)

EU dossier containing product description, CPSR, GMP statement, method of manufacture, safety/claims data, and labeling.

Store PIF for 10 years post last batch; Include labeling and claims evidence; RP maintains the PIF in the EU

Preservatives

Antimicrobial systems to control bacteria, yeast, and mold; selection considers pH, water activity, packaging, and regulatory limits.

Evaluate phenoxyethanol/ethylhexylglycerin blend; Preservative-free claims need risk controls; Test yeast/mold coverage

Primary vs Secondary Packaging

Primary packaging contacts the formula; secondary is outer or additional (cartons, sleeves). Impacts stability, safety, and sustainability.

Tube is primary; carton is secondary; Migration testing for primary only; Optimize secondary for e‑commerce

QC/QA (Quality Control and Assurance)

QC tests and releases materials/batches; QA oversees systems, documentation, audits, and continuous improvement.

QC released the bulk; QA approved the deviation; Tighten specs on viscosity and pH

REACH (EU Chemicals Regulation)

EU chemicals framework requiring registration/evaluation; impacts certain cosmetic ingredients and imposes restrictions.

Check SVHC status of the solvent; Microplastics restriction may apply; Ensure REACH compliance for imports

Retinoids

Vitamin A derivatives (retinol, retinal) used for anti-aging; require stability, irritation management, and regulatory compliance. Retinoic acid is a drug.

Retinol needs antioxidant stabilization; Irritation risk requires careful claim language; Comply with regional retinoid limits

Safety Assessment

Expert evaluation of ingredient exposure and toxicology to determine product safety (e.g., SCCS methodology in EU).

Toxicologist concluded safe at 2% use; MoS > 100 meets criteria; Update assessment after fragrance change

SDS (Safety Data Sheet)

Hazard communication document for substances/mixtures per GHS; mainly for raw materials handling, storage, and transport.

Request SDS for the new solvent; Follow PPE per SDS; Finished goods don’t require SDS unless hazardous

Shelf Life

Time a product remains within specification under defined storage; may include unopened (expiry) and in-use (PAO).

Assign 30‑month unopened shelf life; Use-by date for <30 months in EU; Monitor real-time stability annually

SPF/UV Filters

Sun protection factor and UV filter systems (mineral or organic). Testing and claims vary by market; in the U.S., sunscreens are OTC drugs.

SPF 30 target with broad-spectrum claim; Use critical wavelength for UVA; Select mineral vs organic filters

Stability Testing

Program to evaluate product integrity over time (appearance, odor, pH, viscosity, microbes) under accelerated and real-time conditions.

12 weeks at 40°C/75% RH; 5 cycles freeze–thaw; Photostability under UV exposure

Titanium Dioxide

Inorganic pigment/UV filter used for opacity and sun protection; particle size and coating impact performance and regulatory handling.

Use TiO2 for opacity in lotion; Nano grade affects SPF and aesthetics; Check regulatory status in region

Traceability

Ability to track materials and finished goods through the supply chain via lot codes and records for quality and recalls.

Scan lot codes through 3PL; Implement supplier trace mapping; Mock recall tested in 2 hours

Vegan Claim

Positioning indicating no animal-derived ingredients or byproducts; requires supplier verification and clarity on testing policies.

Replace beeswax with candelilla; Verify no animal-derived processing aids; Use third-party vegan certification

Viscosity

Resistance to flow; key QC parameter affecting sensorials, pumpability, and stability. Measured by viscometers (e.g., Brookfield).

Spec: 6,000–8,000 cP; Brookfield RV spindle 4 @10 rpm; Viscosity drift after fragrance addition

Water Activity (aw)

Measure of unbound water available for microbial growth; informs preservative strategy and packaging.

aw < 0.6 reduces microbial risk; High aw balm needs preservation; Measure aw after humectant changes

Water-in-Oil (W/O) vs Oil-in-Water (O/W) Emulsions

Two emulsion types defined by the continuous phase; choice affects feel, stability, and claim performance.

Use W/O for water resistance; O/W gives lighter skin feel; Switching phase inverted stability

Yield (Batch Yield)

Actual output versus theoretical output; key manufacturing KPI impacting COGS and planning.

Achieved 98% of theoretical; Investigate losses at transfer; Tighten process to improve yield

Zinc Oxide

Inorganic UV filter/pigment used in mineral sunscreens and color; particle treatment and dispersion control aesthetics and protection.

Non‑nano ZnO for mineral SPF; Sheer dispersion reduces whitening; Confirm heavy metal specs
