What botanical species does jasmine sambac concrete come from, and where is it sourced?
Jasmine sambac concrete is the solvent extract of the flowers of Jasminum sambac (L.) Aiton — the "Xiao-hua molihua" (small-flower jasmine / Arabian jasmine), one of the classic jasmine species used for the world-famous jasmine concrete / absolute. Top sources fresh jasmine sambac flowers from Guangxi (Hengxian / Hengzhou, the "jasmine capital of China") and adjoining regions, the traditional jasmine-flower belt.Top declares the botanical name on every COA. Note this is a solvent-extracted concrete (floral wax + the heady jasmine aroma concentrate) of fresh jasmine blossoms — a natural, flower-origin material, not a distilled oil.Top keeps the species declaration so...
Do you supply diluted or blend-ready jasmine sambac concrete?
Yes. Beyond the neat concrete, Top can supply diluted forms (for example, pre-dissolved in a carrier oil such as jojoba / MCT, or in food-grade ethanol at a defined percent) for easier handling and lower-cost trials, or a pre-blended base per your formula.Because this is a waxy concrete (not a volatile oil), dilution is by melting and blending with carrier oil or ethanol. Dilution medium and concentration are agreed per order and stated on the COA.Note that dilution changes the measured specification window, so the COA always declares the actual concentration and base. Neat lots remain the default for buyers...
How do you ensure batch-to-batch consistency and traceability?
Top controls consistency through Q/XXXX and per-batch GC-MS benzyl / indole floral fingerprint matched to the reference profile: each lot is matched (melting point, refractive index, yield within band, benzyl-alcohol/acetate/indole ratio present). Traceability runs flower origin → extraction → concrete with a lot-specific ledger and retention sample.If your application needs tight tolerances, tell Top and we can select lots from the same orchard/harvest or blend to a target floral profile. Every shipment carries a lot number linking to the COA and GC-MS on file.Top shares the QC ledger with GD27 jasmine sambac essential oil for fresh-flower continuity.
What does jasmine sambac concrete look and smell like?
AppearanceA soft, waxy, paste-to-semi-solid mass, orange-brown to deep brown (a true "concrete" — it contains floral wax, so it is not fluid at room temperature; warm to soften). OdourThe classic intense, indolic, sweet, waxy, rich jasmine character — the heady "white floral" signature, not a single-note synthetic.Because solvent extraction captures the full floral complex (benzyl alcohol / benzyl acetate / indole / cis-jasmone / methyl jasmonate), the aroma is true natural jasmine sambac, not a simplified fragrance. Sensory evaluation follows an in-house panel; Top provides the odour description on the COA and can supply a reference sample. (Reminder: it is...
What after-sales support do you provide?
Top provides ongoing support: lot traceability and re-test within shelf life using the retention sample, documentation re-issue (COA / SDS / origin / health cert copies), formulation advice (melting/dilution in carrier oil or food-grade ethanol, grade selection for stability, food vs cosmetic labeling, oxidation-control note for this waxy, aroma-sensitive concrete) and a responsive complaint channel. For LTA buyers we assign a dedicated contact and periodic review of grade consistency.We treat the relationship as long-term — the after-sales step is where we protect your production continuity, not an afterthought.
How do you authenticate jasmine sambac concrete and screen for adulteration?
Top authenticates by: (1) GC-MS benzyl alcohol / benzyl acetate / indole floral fingerprint matched to natural jasmine sambac (the ratio of benzyl alcohol, benzyl acetate, indole, cis-jasmone, methyl jasmonate is the signature; synthetic jasmine lacks the jasmone/jasmonate trace complex); (2) melting point / refractive index / yield against Q/XXXX; (3) solvent residue confirm (GB 5009.262 not detected); (4) species + "fresh flower / solvent concrete" declaration on COA; (5) where required, stable-isotope / spectroscopic naturalness. Every lot ships with COA plus GC-MS. We screen synthetic-jasmine / other flower-wax padding / carrier dilution by the floral fingerprint. Lots failing the...
