oregano flower/leaf/stem water

Oregano flower/leaf/stem water is a water-based solution containing the steam distillate components obtained from the flowers, leaves, and stems of wild marjoram, Origanum vulgare L., a member of the Lamiaceae family. This compound appears as a clear aqueous liquid with a characteristic herbal odor noted at 1.00 % concentration in dipropylene glycol. The material is known by various synonyms including marjoram flower/leaf/stem water, pot marjoram extract, and specific botanical subspecies variants. It is classified chemically as an aqueous solution of natural essential oil constituents and can be referenced via controlled vocabulary databases such as PubChem. The distillate is typically derived by steam distillation, a standard process used extensively to separate volatile aroma compounds from plant material for fragrance and sensorial use.

Oregano flower/leaf/stem water originates biologically from wild marjoram plants, Origanum vulgare, widely found in the Mediterranean and temperate regions. It captures volatile compounds characteristic of the plant's flowers, leaves, and stems. Applications primarily encompass fragrance agents for perfuming and scenting products, where its herbal scent profile contributes to natural and green aromatic accords. The material is recognized under fragrance standards such as IFRA (Global), which provides guidelines for safe use in perfumery. It is not intended for flavor use according to IFRA codes or other relevant regulatory bodies. Thus, its applicability lies mostly in cosmetic and fragrance formulations leveraging its herbal olfactory properties.

This distillate is a water-soluble aqueous solution resulting from steam distillation of Origanum vulgare botanical parts. Its solubility in water facilitates incorporation into various formulations without requiring organic solvents. The herbal odor profile arises from a complex mixture of volatile organic compounds present in the steam distillate. Unlike essential oils, the flower/leaf/stem water contains lower concentrations of hydrophobic terpenoids, favoring a lighter and fresher aromatic character. The absence of significant hazardous classifications per OSHA HCS (29 CFR 1910) and other safety assessments supports its compatibility with fragrance use, subject to recommended concentration limits. Its physical form and chemical nature influence formulation stability and olfactory performance in aqueous or emulsion-based cosmetic products.
