What Is Pterocarpus Marsupium Bark/Wood Extract?
Pterocarpus Marsupium Bark/Wood Extract is obtained from the bark and heartwood of Pterocarpus marsupium, a large hardwood tree native to India and Sri Lanka. The bark and wood are rich in natural polyphenols such as tannins, flavonoids and catechins that lend protective and conditioning properties. For centuries the tree’s reddish sap, known as Indian kino, has been valued in traditional beauty rituals for its ability to add gloss and resilience to hair. Modern cosmetic makers harvest sustainably sourced bark and wood, dry and mill the material then run it through water or gentle alcohol extraction. The liquid extract is filtered, concentrated and spray-dried into a fine powder or supplied as a fluid to formulators. You will most often find this plant-based ingredient in hair conditioners, masks, leave-in serums, nourishing shampoos and scalp treatments where a botanical boost to softness and shine is desired.
Pterocarpus Marsupium Bark/Wood Extract’s Cosmetic Benefits/Uses
In cosmetic formulations this ingredient serves one main purpose.
Hair conditioning: The extract coats the hair shaft with lightweight polyphenols that smooth the cuticle, making strands feel softer and look glossier. It helps reduce tangles and frizz, improves manageability and provides a subtle protective film that minimizes moisture loss without weighing hair down.
Who Can Use Pterocarpus Marsupium Bark/Wood Extract
This botanical conditioner suits most hair and scalp types including oily, normal and dry. Its lightweight polyphenols do not clog follicles so even those prone to buildup or an easily irritated scalp usually tolerate it well. Individuals with a known allergy to legumes or other Fabaceae plants should proceed carefully as cross-sensitivities are possible.
The extract is entirely plant derived and obtained without animal by-products or testing, making it acceptable for vegans and vegetarians.
No published data indicate that topical use poses a special risk to women who are pregnant or breastfeeding. That said this is not medical advice and anyone who is expecting or nursing should check with a healthcare professional before adding new personal care products.
Pterocarpus Marsupium Bark/Wood Extract does not cause photosensitivity, and there are no known ingredients it conflicts with in routine hair care formulas.
Potential Side Effects/Adverse Reactions
Reactions to topical Pterocarpus Marsupium Bark/Wood Extract differ between individuals. The points below outline potential side effects yet most people will not experience them when the ingredient is correctly formulated.
- Allergic contact dermatitis – rare redness, itching or rash in those sensitive to plant polyphenols or the Fabaceae family
- Scalp irritation – mild burning or tingling if applied to broken or highly sensitive skin
- Dryness in very compromised hair – high tannin content can feel astringent on severely damaged strands
- Temporary light staining – the natural reddish hue may faintly tint very porous blonde or gray hair until the next wash
If discomfort, rash or any unwanted change occurs stop use immediately and seek advice from a qualified medical professional.
Comedogenic Rating
Rating: 0–1 (essentially non comedogenic). The extract is composed mainly of water soluble polyphenols with negligible oils or waxes, so it does not form a heavy film that could block pores. Typical use levels in hair products are low and rinse off, further reducing any pore clogging risk.
Generally suitable for people prone to acne or breakouts.
Bear in mind the overall formula matters, so check companion ingredients if you are watching for pore cloggers.
Summary
Pterocarpus Marsupium Bark/Wood Extract is a plant based hair conditioner that smooths cuticles, fights frizz and adds light gloss through a thin polyphenol coating that locks in moisture without weight. While not as famous as argan or coconut oil it is gradually finding its way into clean and vegan hair care lines for those after a botanical edge.
The ingredient is viewed as low risk for most users with only rare allergy or irritation reports. Still, patch test any new product containing it so you can be confident your skin and scalp stay happy.
