The definitions below are provided as general educational guidance. Regulatory terms and standards may vary by market and change over time. Always verify current requirements with the relevant authority or a qualified professional before making compliance decisions.
AHA (Alpha Hydroxy Acid)
A category of water-soluble acids derived from natural sources — including glycolic acid (from sugar cane), lactic acid (from milk), and citric acid (from citrus). Used in skincare as chemical exfoliants to remove dead skin cells, improve texture, and support radiance. Commonly found in serums, toners, and peels. Concentration and pH affect both efficacy and regulatory classification.
Active Ingredient
An ingredient included in a formula specifically for its functional benefit — such as retinol for anti-ageing, niacinamide for brightening, or salicylic acid for acne control. Distinguished from excipients or base ingredients that provide texture, stability, or preservation. In regulated markets, certain active concentrations require specific regulatory classification or registration.
Ampoule
A concentrated single-use skincare dose, typically sealed in a glass vial and applied as a treatment course. Higher in active ingredient concentration than a serum, and formulated without preservatives in some cases due to the sealed, single-use format. Distinguished from serums by their delivery format and typically higher potency. See our blog: Serum vs Ampoule — What’s the Difference?
Attar / Ittar
Traditional concentrated perfume oil, typically distilled from botanical ingredients — most famously oud — into a carrier oil. The original Arabic fragrance format. Oil-based and therefore Halal-certifiable. Carries deep cultural significance in GCC markets and is growing globally in the premium and artisan fragrance segment. See our blog: Oil vs Alcohol-Based Perfume.
Batch Record (BMR — Batch Manufacturing Record)
A complete documented record of how a specific production batch was manufactured — including raw materials used, quantities, equipment, processing steps, in-process checks, and the personnel involved. Required under GMP and essential for full traceability. Available to clients on request for all production orders placed with us. See our blog: Batch Record Keeping Explained.
BHA (Beta Hydroxy Acid)
An oil-soluble acid — most commonly salicylic acid — used in skincare for its exfoliating and anti-inflammatory properties. Because it is oil-soluble, it can penetrate into pores, making it particularly effective for acne-prone and congested skin. Commonly used in cleansers, toners, and targeted spot treatments.
Certificate of Analysis (CoA)
A document issued for each production batch confirming that the finished product meets its defined specification. Typically includes measured values for pH, density, viscosity, appearance, colour, and odour — compared against approved specification ranges. A CoA is available on request (additional service). Commonly required by retailers, regulators, and export markets as evidence of product quality. See our blog: How to Read a Certificate of Analysis.
Certificate of Conformance (CoC)
A document confirming that a production batch was manufactured in accordance with the agreed specification and under the applicable quality management standards. Distinct from a CoA — the CoC confirms the manufacturing process was compliant; the CoA confirms the finished product meets specification. Both are available on request (additional service).
Certificate of Free Sale (CFS)
A document issued by a competent authority in the country of manufacture — in the UAE, typically the Ministry of Economy — confirming that the product is legally manufactured and freely sold in that country. Required by most export markets including Saudi Arabia (SFDA), Malaysia, and many others as part of the import registration documentation.
Challenge Testing
A microbiological test used to confirm that the preservative system in a cosmetic formula is effective — by deliberately introducing microorganisms and measuring their reduction over time. Required for most cosmetic products across regulated markets as part of demonstrating product safety. Also known as Preservative Efficacy Testing (PET). See our blog: Challenge Testing Explained.
CPNP (Cosmetic Products Notification Portal)
The EU’s mandatory online system through which all cosmetic products must be notified before they can be placed on the EU market. Notification is submitted by a Responsible Person established in the EU or EEA. Requires full INCI formula, product information, and label details. There is no approval waiting period — the product may enter the market once notified. See our blog: What is CPNP?
CPSR (Cosmetic Product Safety Report)
A safety assessment document required under EU cosmetics regulations before a product can be placed on the market in Europe. Prepared by a qualified cosmetic safety assessor, it evaluates the safety of each ingredient and the finished formula. Required for EU CPNP registration. If you are manufacturing for EU export, we can guide you on the documentation needed for your safety assessor.
EDP / EDT / EDC (Perfume Concentrations)
The concentration of fragrance oil in a perfume determines its category, longevity, and price positioning. As a general guide: Eau de Cologne (EDC) typically contains around 2–4% fragrance oil; Eau de Toilette (EDT) around 5–15%; Eau de Parfum (EDP) around 15–20%; and Parfum or Extrait 20–30%+. Higher concentration generally means longer longevity. We manufacture across all concentration formats. See our blog: How Concentration Affects Cost.
Emulsification
The process of combining two immiscible liquids — typically water and oil — into a stable, uniform mixture using an emulsifier. Fundamental to the manufacturing of lotions, creams, and many serums. The stability and texture of an emulsion depends on the emulsifier system, processing temperature, mixing speed, and the ratio of oil to water phases. See our blog: Emulsification in Cosmetics.
Fill Weight
The quantity of product placed in each container, measured by weight (grams) or volume (millilitres). Fill weight is the primary quality control check during filling operations — every nth unit is weighed during production to confirm it is within the agreed tolerance of the target fill. The fill weight and tolerance are specified in the batch manufacturing record.
Fragrance Brief
A document provided to a perfumer describing the desired fragrance outcome — the emotional target, the intended use, the fragrance family direction, key notes, references, budget per kilogram, and any restrictions. The quality of the fragrance brief directly affects the quality and speed of the development process. See our blog: What is a Fragrance Brief?
GMP (Good Manufacturing Practice)
An internationally recognised standard for the manufacture of cosmetics, pharmaceuticals, and food products. GMP certification covers the facility, equipment, personnel, processes, and documentation required to consistently produce products that meet defined quality standards. Our Sharjah facility is GMP certified — meaning every product we manufacture is produced under controlled, documented, and auditable conditions. GMP certification is increasingly required by retailers and export markets as a condition of supplier approval. Learn more about our certifications. See our blog: What is GMP Certification?
GSO (Gulf Standards Organisation)
The Gulf Cooperation Council body responsible for technical standards and regulations across GCC member states. GSO 1943 is the technical regulation for cosmetics that provides the harmonised regulatory framework across UAE, Saudi Arabia, Kuwait, Qatar, Bahrain, and Oman. Broadly aligned with EU Regulation 1223/2009. See our blog: GCC Technical Regulation on Cosmetics.
Halal
Arabic for “permissible” — in cosmetics, refers to products formulated and manufactured in compliance with Islamic law. Halal cosmetics are free from porcine derivatives, fermentation-derived ethanol, non-Halal-slaughtered animal ingredients, and are manufactured with appropriate facility segregation. Certification is issued by accredited bodies including ESMA in the UAE, JAKIM in Malaysia, and MUI in Indonesia. See our blog: Halal Certification for Cosmetics — A Complete Guide.
IFRA (International Fragrance Association)
The global industry body that publishes safety standards for fragrance ingredients used in cosmetics. IFRA Standards restrict the use of specific fragrance ingredients in different product categories based on safety data. An IFRA Certificate of Conformity confirms that a fragrance blend complies with current IFRA Standards at a specified usage level in a specified product category. Required as standard professional practice for any product containing fragrance. See our blog: What is IFRA Compliance?
INCI (International Nomenclature of Cosmetic Ingredients)
The standardised international naming system used to list cosmetic ingredients on product labels. INCI names are typically in Latin or English, and must be listed in descending order of concentration on product packaging in most regulated markets — including the UAE and EU. Accurate INCI listing is a regulatory requirement and part of the product dossier we prepare for each formula.
ISO 9001
An international standard for quality management systems published by the International Organization for Standardization. ISO 9001 accreditation confirms that an organisation’s quality management processes meet defined international standards. Our facility holds ISO 9001:2015 accreditation, assessed and renewed by an independent certification body. Learn more.
Job Work
A production model where the client supplies some or all of the materials and the manufacturer provides the production service — filling, capping, labelling, packing. Also called toll manufacturing. The client retains ownership of materials and finished product throughout. Common when brands want to control their formula IP, process existing inventory, or use their own approved packaging. See our blog: What is Job Work? and our Job Work service page.
Maceration
The resting period after fragrance oil is blended with a carrier, during which the molecular interactions between fragrance components and carrier stabilise. Skipping maceration produces a fragrance that smells underdeveloped or harsh. Simple formulas may require 24–48 hours; complex fine fragrances often require 1–4 weeks. A key step that significantly affects fragrance production lead time. See our blog: Mixing, Maceration, and Chilling Explained.
MOHAP
UAE Ministry of Health and Prevention. The regulatory authority responsible for cosmetics registration in the UAE. MOHAP manages product registration through the Montaji online platform. All cosmetics sold in the UAE — including UAE-manufactured products — must be registered with MOHAP before market placement. Registration typically takes 8–12 weeks for standard cosmetics. See our blog: How to Register with MOHAP.
Montaji
The UAE MOHAP online platform for product registration and licensing. Importers, manufacturers, and brand owners submit cosmetics registration applications through Montaji. A UAE-registered entity is required to access Montaji — international brands typically work through a UAE manufacturer or authorised agent who manages the submission on their behalf.
MOQ (Minimum Order Quantity)
The smallest production quantity a manufacturer will accept for a given product. MOQs exist because of fixed production costs — setup, batch preparation, cleaning, and documentation — that make very small runs impractical. MOQs vary by product type, formula complexity, and packaging. We offer flexible MOQs that allow brands to start with smaller runs and scale as they grow.
MSDS (Material Safety Data Sheet)
A document providing detailed information about a product’s composition, physical and chemical properties, health and safety hazards, storage requirements, and handling instructions. Required for shipping and export — particularly for products classified as dangerous goods for transport purposes. An MSDS is available on request (additional service).
NDA (Non-Disclosure Agreement)
A legally binding agreement that prevents one or both parties from disclosing confidential information to third parties. Standard practice in cosmetics manufacturing — signed before any formula information is shared with a manufacturer, fragrance house, or other service provider. Protects your formula IP, your supplier relationships, and your commercial plans. We sign NDAs as standard before any formula discussion begins.
OEM (Original Equipment Manufacturing)
A manufacturing arrangement where the client supplies their own formula and the manufacturer produces it to the client’s specification. The client owns the formula. Distinct from private label (where you use the manufacturer’s formula) and ODM (where the manufacturer develops the formula on your behalf). Learn more about our OEM service.
ODM (Original Design Manufacturing)
A manufacturing arrangement where the manufacturer develops a new formula from scratch based on the client’s brief. The resulting formula belongs exclusively to the client. Requires an R&D and development phase before production — including formulation, sampling, and approval. Learn more about our ODM service.
Oud (Agarwood)
A resinous heartwood produced by the Aquilaria tree. Considered the most valuable natural fragrance ingredient in the world. Prized in Arabic perfumery for its complex, woody, and lingering character with exceptional longevity. Geographic origin significantly affects quality and price — Cambodian, Indian, Malay, and Papua New Guinean ouds are among the most valued. See our blog: Middle Eastern Fragrance Preferences.
PAO (Period After Opening)
The open jar symbol followed by a number and “M” — for example “12M” — indicating how many months a product is safe to use after opening. Required on cosmetics labels when the product has a shelf life of 30 months or more. If the shelf life is less than 30 months, a date of minimum durability (best before date) is used instead. Your manufacturer’s stability testing data determines the appropriate PAO period.
Preservative System
The combination of preservative ingredients in a formula that protect it from microbial contamination throughout its shelf life. An effective preservative system must inhibit the growth of bacteria, yeasts, and moulds under normal conditions of use and storage. Preservative efficacy is verified through challenge testing. The choice of preservatives affects whether a product can be marketed as “paraben-free”, “natural”, or Halal-compliant. See our blog: Preservative Systems in Skincare.
Private Label
A manufacturing arrangement where a brand sells products manufactured by a third party under their own brand name. The manufacturer owns the formula; the brand applies their identity. The fastest and most cost-effective route to market for new brands — no R&D required and products are available for sampling immediately. Learn more about our private label service.
SFDA (Saudi Food and Drug Authority)
The Saudi government body responsible for regulating cosmetics in Saudi Arabia. All cosmetics imported into Saudi Arabia require separate SFDA registration independent of UAE MOHAP clearance. SFDA registration is managed through the GFSIS portal by a Saudi-registered importer or agent. Typically takes 12–20 weeks. See our blog: How to Register Cosmetics with SFDA.
Stability Testing
A series of tests conducted to determine and verify the shelf life of a cosmetic product. Accelerated stability testing exposes the product to elevated temperature and humidity conditions to predict long-term performance. Real-time stability testing monitors the product under normal storage conditions over its claimed shelf life. Stability testing is required in most regulated markets and is part of the product safety documentation package. We coordinate stability testing through accredited third-party laboratories. See our blog: How Cosmetic Products Are Stability Tested.
Toll Manufacturing / Job Work
A manufacturing arrangement where a client supplies their raw materials and/or formula, and the manufacturer provides the production facility, equipment, and labour to process them. The client retains ownership of materials and finished product. Commonly used by brands that have their own approved formula and raw material supply, but require manufacturing capacity. Learn more about our Job Work service.
Viscosity
A measure of a liquid’s resistance to flow — how thick or thin it is. Low viscosity liquids (toners, serums, fragrances) flow easily. High viscosity products (thick creams, balms) flow slowly or not at all. Viscosity is typically measured in centipoise (cP). It is a critical parameter for filling machine selection — providing viscosity data to your manufacturer when briefing a filling project enables accurate equipment matching and fill weight tolerances.
Waterless / Anhydrous Formulation
A product formulated without water — using oils, butters, waxes, or powders as the primary base. Because water is absent, anhydrous formulas typically do not require traditional preservatives and have a naturally longer shelf life. Common in solid skincare, hair care, balms, and concentrated formats. A growing category driven by sustainability and packaging reduction goals. See our blog: Waterless Skincare.
