Cosmetic raw materials

Camellia oil is a cold-pressed or solvent-refined plant oil extracted from the seeds of Camellia japonica, a species native to Japan, Korea, and southern China. Used in Japan for over a thousand years for hair and skin care. Traditional production centers include the Goto Islands in Nagasaki and Izu Oshima off Tokyo. Rich in oleic acid with a light, non-greasy feel.

Rice bran extract is derived from the pericarp and germ fractions of milled Oryza sativa. Long used in Japanese household skincare via togijiru (rice-rinsing water) and nukabukuro (rice-bran poultices). The extract concentrates gamma-oryzanol, ferulic acid, tocopherols, and B-vitamins, and pairs well with other rice-derived materials.

Galactomyces ferment filtrate is the clear liquid obtained from the culture of Galactomyces yeast. Studied for skin-conditioning and moisturizing effects. Japanese manufacturers produce the ingredient under INCI-recognized generic names; this platform lists only generic producers, not proprietary brand preparations.

Sake lees (酒粕, sakekasu) is the residual solid obtained after pressing fermented rice mash in sake brewing. Used in cosmetics for amino acids, peptides, and yeast-derived bioactives. Major sake-producing regions (Niigata, Nada, Fushimi, Saijō) supply upstream material. Well-suited to sustainability narratives as an upcycled brewing byproduct.

Perilla frutescens, known in Japan as shiso (紫蘇), is a herb of the mint family used in Japanese cooking and traditional medicine. The leaves contain rosmarinic acid, perillaldehyde, and anthocyanins (in the red variety). Used in cosmetics for soothing and antioxidant positioning.

Hinoki (Chamaecyparis obtusa) is a coniferous tree endemic to Japan and Taiwan, famous for use in Shinto shrine construction and onsen bath fittings. The essential oil is steam-distilled from hinoki wood, leaves, or twigs. Dominant compounds include hinokitiol, α-pinene, and sesquiterpenes. Distinct from hiba (Thujopsis dolabrata).

Yuzu (Citrus junos) is a Japanese citrus with a distinctive aromatic profile. Kōchi prefecture is Japan's largest producer. The peel yields essential oil dominated by d-limonene, while aqueous extracts carry flavonoids and citric acid. Used in fragrance, bath products, and skin-conditioning toners.

Fucoidan is a sulfated polysaccharide extracted from brown seaweeds, most commonly mozuku (Cladosiphon okamuranus) from Okinawa and kombu (Saccharina japonica) from Hokkaidō. Studied for moisturizing, immune-modulating, and antioxidant positioning. Sold as both a cosmetic ingredient and a functional food supplement.

Kuromoji (Lindera umbellata) is a deciduous shrub in the Lauraceae family, native to Honshu, Shikoku, and Kyushu mountain forests. Traditionally used for tea-ceremony toothpicks and premium wagashi picks. Steam-distilled essential oil offers a fresh, citrusy-woody profile with major components linalool, 1,8-cineole, α/β-pinene. Positions as a uniquely Japanese alternative to hinoki with satoyama sustainability credentials.

Sake extract is a concentrated preparation from Japanese rice wine, typically aqueous or hydro-alcoholic extraction capturing amino acids, peptides, and flavor actives. Cosmetic applications use non-alcoholic or low-alcohol fractions for moisturizing and brightening claims; food applications use sake concentrate in seasonings, glazes, and bakery.

Astaxanthin is a carotenoid pigment produced primarily by microalgae (Haematococcus pluvialis), known for strong antioxidant capacity. Japanese production pioneered by Fuji Chemical Industry and ENEOS uses closed-system microalgae cultivation. Multiple Japanese FFC notifications cite astaxanthin for eye health, skin health, and antioxidant support.

GABA is a non-protein amino acid produced commercially in Japan by lactic-acid bacterial fermentation or chemical synthesis. Japan is a global leader in functional-food applications of GABA, with thousands of FFC notifications citing stress reduction, sleep quality, and blood-pressure support.

Rice-derived glucosylceramide is a sphingolipid extracted from rice germ or rice bran, used in both ingestible supplements and topical cosmetics. Japanese FFC notifications cite effects on skin moisture retention. Production leverages Japan's rice-milling byproducts, aligning with sustainability positioning.

Proteoglycan extracted from salmon nasal cartilage, developed at Hirosaki University in Aomori Prefecture. Water-retention capacity approximately 1.3 times that of hyaluronic acid.

A tropical herb native to Okinawa. Research at University of the Ryukyus (Prof. Tawada) demonstrated lifespan extension of 22.6% in nematode studies.

Essential oil from Thujopsis dolabrata, designated as Aomori Prefecture's official tree. Contains ~2% hinokitiol with strong antimicrobial properties.

Small citrus native to Ryukyu Islands. Contains the highest nobiletin concentration among citrus fruits.

Sulfated polysaccharide from Okinawa mozuku (Cladosiphon okamuranus). Highest fucoidan content among commercial seaweeds (up to 85-90% purity).

Amino acid unique to tea (Camellia sinensis). Commercial production led by Taiyo Kagaku's enzymatic method.

Japanese mugwort species, distinct from Korean Artemisia asiatica. Long-standing use in kampo and Okinawan cuisine (Fuchiba).

East Asian medicinal herb known in kampo as Jūyaku. Star ingredient in K-Beauty, with growing global demand.

Pearl protein (conchiolin) and mineral compounds extracted from akoya pearl oysters and shells. Mikimoto Pharmaceutical (ISO 22716 certified) developed multiple proprietary pearl-derived ingredients since 1966 and offers skincare OEM services.

Soy isoflavones (aglycone and glycoside forms) and S-Equol produced by Lactococcus 20-92 fermentation. Otsuka Pharmaceutical's 'Equelle' (2014) was the world's first commercial fermented-soy Equol supplement. Only ~50% of Japanese (~30% of Western) women naturally produce Equol from dietary soy.

Glucosylceramide extracted from apple pomace (juice-extraction residue). Developed through Hirosaki University research as an upcycling material that transforms apple processing waste into premium cosmetic and food ingredients.

Plant-type ceramide (glucosylceramide) extracted from konjac corms. Konjac contains 7-15× higher ceramide concentration than rice or corn sources, making it the most cost-effective feedstock for plant ceramide extraction.

Activated charcoal produced by charring Moso Bamboo at 1,000°C in traditional earth kilns, pulverized to micron-scale particles. Classified in Japan as 'plant charcoal color' food additive (植物炭末色素).

Japanese natural spring water from officially designated sources. The Ministry of Environment has selected 100 Famous Waters (1985) and 100 Heisei Period Famous Waters (2008), totalling 200 sites. Japan's first domestic mineral water was Fuji Mineral Water's 'Nihon Evian' (1929).
