Key Benefits

Natural astringency and ≥ 50 % catechin polyphenols help tone gums & support oral health.

Potent antioxidants neutralise free radicals, protecting cells from oxidative stress.

Warm brown hue provides a clean-label colour alternative in lozenges & beverages.

Plant-based, non-GMO extract delivered by ethanol–water process for transparent sourcing.

Q: What tannin level does this Acacia catechu extract deliver, and why is consistency critical for formulation?

A: The powder is standardised to at least 50 percent combined catechin and epicatechin tannins, confirmed by UV spectrophotometry on every batch.  Consistency matters because tannins drive astringency, antioxidant capacity, flavour, and colour.  When you know every kilogram contains the same polyphenol load, you can dose oral-care rinses, digestive capsules or cosmetic masks accurately, avoiding batch-to-batch variability that might otherwise alter mouth-feel, shade or efficacy.  Reliable potency also simplifies regulatory documentation and label claims.

Q: How does Acacia catechu compare with aluminium astringents in gum-care products?

A: Aluminium salts tighten tissue mechanically but provide no polyphenol antioxidant benefit and raise clean-label concerns.  Acacia catechu offers a dual mode: natural astringency plus powerful antioxidants that may help fight oral free radicals.  It is aluminium-free, vegan and compatible with fluoride, xylitol and herbal oils.  Formulators can replace synthetic astringents with a botanical alternative that supports gum tone while contributing consumer-friendly provenance and marketing appeal.

Q: Will the dark colour stain teeth or finished oral products?

A: Used at ≤ 0.5 percent in mouth-wash or toothpaste, the extract imparts a pale amber tint far below staining thresholds.  Its polyphenols may even precipitate with salivary proteins to form a protective film that discourages plaque adhesion.  In beverages below 0.1 percent the hue is a pleasant tea-like warmth without sediment.  Therefore, staining risk is minimal, and colour can be adjusted by lowering dosage if required.

Q: Can I combine this extract with live probiotics in digestive supplements?

A: Yes, but separate them physically or by coating because high tannin concentrations can inactivate sensitive bacterial strains.  Dual-chamber beadlets or enteric-coated capsules work well.  Stability studies show Lactobacillus viability above 90 percent when catechu is blended at a 1:5 ratio and stored under 25 °C.  Always run pilot stability on your specific strains and adjust excipient matrix accordingly.

Q: What about residual solvent from the ethanol-water extraction—does any remain?

A: Residual ethanol is < 0.3 percent w/w (under 2 500 ppm), well below USP <467> limits.  Each lot’s Certificate of Analysis confirms residual solvent, heavy metals and microbiology compliance.  Vacuum concentration plus spray-drying removes nearly all ethanol while protecting heat-sensitive polyphenols.  The finished powder meets global supplement and food safety standards.

Q: How must Acacia catechu extract be declared on labels in the US and EU?

A: In US supplement facts list “Acacia catechu heartwood extract (source of tannins).”  In Cosmetic INCI use Acacia Catechu Extract.  EU food supplements label as “Acacia catechu extract” per Regulation 1169/2011, plus country of origin, India.  Disclose any co-processed allergen traces if applicable, though our extract is produced in an allergen-controlled facility.
