About this category

The Cosmetics glossary covers INCI-recognized cosmetic ingredients used in Japanese personal care manufacturing, spanning plant extracts, fermented derivatives, marine ingredients, oils, surfactants, and quasi-drug actives. The Japanese cosmetic ingredient catalogue is one of the most diverse in the world, combining ingredients with thousands of years of traditional cosmetic use (rice bran, camellia oil, seaweed) with cutting-edge biotechnology actives (recombinant collagen, exosome-style derivatives, post-biotic ferments). This glossary aims to provide neutral, dictionary-style definitions of how each ingredient is produced, what its INCI name is, what concentration ranges are typical, and how it is regulated in Japan and major export markets.

Historically, Japanese cosmetic ingredients evolved from Heian-period (794–1185) court rituals — where rice bran (komenuka) was used as a cleansing powder and camellia (Camellia japonica) seed oil dressed hair — through Edo-period (1603–1868) refinement of geisha-grade preparations to the modern era of industrial chemistry. Shiseido, founded in 1872 as Japan's first Western-style pharmacy, introduced laboratory methods to cosmetic ingredient development in the early 20th century. The post-war period saw the introduction of fermentation-based actives, beginning with Pitera-style yeast filtrates in the 1970s and continuing through marine collagen peptides in the 1990s and post-biotic ferments in the 2010s. Each generation of innovation built on the preceding traditions rather than replacing them: a contemporary J-beauty serum might contain a 17th-century camellia oil base, a 1970s Galactomyces ferment, and a 2020s recombinant peptide.

In the modern marketplace, INCI nomenclature provides the international common reference for ingredient identity. Japan participates in the INCI system through the Japan Cosmetic Industry Association (JCIA), which maintains the Japanese Standards of Cosmetic Ingredients (JSCI) — the equivalent of the US Cosmetic Ingredient Review and the EU CosIng database. JSCI lists over 18,000 ingredients with Japanese names and INCI cross-references. The Pharmaceuticals and Medical Devices Agency (PMDA) maintains parallel quasi-drug positive and negative lists. For each ingredient in this glossary, definitions cover: INCI name, common Japanese trade name(s), botanical source or chemical synthesis route, typical use level, principal cosmetic functions (e.g. emollient, antioxidant, brightening), regulatory status in JP/EU/US/CN/KR, and notable clinical evidence where available.

Users of this glossary include international formulators verifying the identity of a Japanese supplier's product, regulatory specialists mapping a JSCI name to an INCI/CosIng entry, R&D teams researching new ingredient categories, and education-focused readers seeking neutral background on Japanese beauty science. Each entry is written to be self-contained but includes cross-references to related ingredients in other glossary categories (Food, Supplements, Traditional) and to relevant Sourcing categories where suppliers are listed. We avoid marketing language and do not rank or recommend ingredients; the goal is precise definitions buyers can use as a reference document.

For users new to Japanese cosmetic ingredients, we suggest beginning with the most commonly encountered categories — fermented yeast filtrates, marine collagen, plant extracts (camellia, rice bran, green tea), and quasi-drug actives (tranexamic acid, arbutin, niacinamide) — before moving into specialty marine, kampo-derived, and biotechnology-derived ingredients. Where possible, definitions cite original Japanese-language sources alongside English-language regulatory references, and note where INCI naming conventions differ from Japanese trade or scientific naming.

Key facts

Nomenclature framework
INCI (International Nomenclature of Cosmetic Ingredients) is the global standard; Japan maintains the Japanese Standards of Cosmetic Ingredients (JSCI) administered by JCIA, listing over 18,000 ingredients with Japanese-INCI cross-references.
Heritage
Japanese cosmetic ingredients span Heian-period (794–1185) traditional materials such as rice bran and camellia oil, through Edo-period (1603–1868) geisha-grade preparations, to modern fermentation and biotechnology actives industrialized from the 1970s onward.
Regulatory framework
Cosmetics are regulated under Japan's Pharmaceuticals and Medical Devices Act (PMD Act, 薬機法); ordinary cosmetics use a positive/negative list with self-certification, while quasi-drugs (iyakubugaihin, 医薬部外品) require pre-market approval from PMDA.
Ingredient categories covered
Plant extracts (botanical actives, oils), fermented derivatives (yeast filtrates, post-biotics), marine ingredients (collagen, fucoidan, algae actives), surfactants, emollients, polymers, preservatives, and quasi-drug actives (whitening, anti-acne, anti-aging).
Cross-market mapping
Each glossary entry where applicable maps INCI name to JSCI registration, EU CosIng entry, US PCPC dictionary listing, China IECIC 2021 status, and Korea KCIA registration to support cross-border formulation work.

Regulatory at a glance

Cosmetic ingredients are regulated under Japan's Pharmaceuticals and Medical Devices Act (PMD Act), which divides personal care products into ordinary cosmetics and quasi-drugs. Ordinary cosmetics may be self-certified by the manufacturer using a positive/negative list framework; the PMDA maintains lists of prohibited and restricted ingredients along with a positive list of UV filters and preservatives. Quasi-drug actives require pre-market approval and substantial efficacy and safety dossiers. Importers should be aware that several ingredients freely usable in EU or US cosmetics — including some peptide actives, certain plant extracts, and select preservative systems — are restricted or unlisted in Japan, requiring supplier consultation before formulation work begins. For cross-border alignment, buyers should map each ingredient against EU CosIng (which integrates with Annexes II–VI of EC Regulation 1223/2009), the US Personal Care Products Council ingredient dictionary (with awareness of MoCRA Facility Registration and Adverse Event Reporting requirements as of December 2023), China's IECIC 2021 and 2024 supplements (under the Cosmetic Supervision and Administration Regulation, CSAR), and South Korea's KCIA / KFDA framework. Halal-certified cosmetic ingredients are increasingly required for Southeast Asian and Middle Eastern markets; the Japan Halal Association and Malaysia Chapter of JAKIM offer certification accepted in most major Muslim-majority markets.

FAQ pour les acheteurs OEM

Q. What makes Japanese cosmetic ingredients distinct from other Asian-origin ingredients?

Japanese cosmetic ingredients combine long manufacturing histories (often 50–100+ years), strict adherence to JCIA's Japan Standards of Cosmetic Ingredients (JSCI), and a regulatory framework that separates general cosmetics from quasi-drugs (薬用化粧品). Many botanical actives have prefecture-level traceability and are listed in CosIng under specific INCI names that carry the Japan-origin signal.

Q. What is the difference between a 'cosmetic' and a 'quasi-drug' ingredient in Japan?

Under Japan's PMD Act (薬機法), 'cosmetic' (化粧品) ingredients are used for cleansing, beautifying, or modifying appearance with mild action. 'Quasi-drug' (医薬部外品) actives have approved efficacy claims like whitening, anti-acne, or hair-growth, and require additional registration. Many Japanese brand-positioning claims (e.g., '美白', 'シワ改善') are only legal in Japan when the active is a quasi-drug ingredient.

Q. Are Japanese cosmetic ingredients listed in EU CosIng and US INCI Dictionary?

Most established Japanese cosmetic ingredients are listed in CosIng (the EU INCI database) and the Personal Care Products Council INCI Dictionary. Newer or proprietary materials may require an INCI name application. Always confirm INCI presence before formulating for EU/US markets.

Q. Which Japanese cosmetic ingredients are subject to China NMPA registration?

China's NMPA maintains the IECIC (Inventory of Existing Cosmetic Ingredients in China) — only listed ingredients can be used without separate filing. Many Japanese plant extracts, especially less common species, are NOT in IECIC and require new ingredient registration (a multi-year process). Common ingredients like Camellia oil, hyaluronic acid, and standard botanicals are widely listed.
