Product Introduction
Slippery Elm Extract Powder comes from the inner bark of Ulmus pumila L., a tree widely distributed across northern China and Central Asia. We extract it with water to preserve the natural mucilage. This mucilage swells in water and forms a slippery, gel-like consistency. It coats surfaces with a smooth film that reduces friction and irritation. It is gentle yet effective, improving solubility and compatibility with your formulations. Our Ulmus pumila L powder disperses well in warm liquids and blends easily into dry mixes. It adds body without synthetic thickeners. For formulators working on throat comfort, digestive support, or skin soothing products, this Elm bark extract offers a reliable plant-based option.

Product Benefits
- Supports Digestive Comfort & Throat Soothing
The mucilage in this Slippery Elm Extract Powder swells in water and forms a slippery, gel-like consistency. It coats surfaces with a smooth film that reduces friction and irritation. This is why formulators use Elm bark extract in throat lozenges, digestive capsules, and demulcent blends.
- Moisturizing & Protective
The polysaccharides in this Ulmus pumila L powder form a protective layer on skin and hair. The small molecular structure allows it to penetrate deeply and lock in moisture, keeping skin and hair hydrated, soft, and easy to manage. It also helps prevent dryness and frizz.
- Skin Soothing & Anti-Aging
Rich in amino acids, this Ulmus pumila L powder helps stimulate collagen production, improving skin firmness and elasticity. Regular use in creams or serums can reduce fine lines and improve uneven skin tone. The ingredient is mild and easily absorbed by the skin.
- 100% Plant-Based & Skin-Friendly
This Slippery Elm Extract Powder is plant-derived, 100% pure botanical. It is hypoallergenic and gentle. As a natural plant ingredient, it is also eco-friendly. It suits all skin and hair types, including sensitive and damaged skin. It meets clean beauty standards. For brands focused on pure, natural, and sustainable concepts, this ingredient is a perfect choice.

Product Application
- Dietary Supplements & Capsules
The most common use. Formulators blend Elm bark extract into capsule and tablet formulas targeting digestive comfort and throat support. The mucilage content provides functional rationale for demulcent claims.
- Throat Lozenges & Syrups
The mucilaginous quality is the whole point here. Lozenges containing Ulmus pumila bark extract powder coat the throat with a protective film. Syrup formulations benefit from the natural body it adds.
- Personal Care & Topical
Skin soothing creams, after-sun products, and barrier lotions use the mucilage for its film-forming and lubricating properties. It suits sensitive-skin positioning.
- Food & Beverage Thickening
In clean-label formulations, slippery elm extract serves as a natural thickener and stabilizer. It can partially replace synthetic gums in certain applications.
- Functional Beverages & Powder Mixes
Slippery Elm Extract Powder disperses in warm liquids. It works in stick packs and drink mixes positioned around "soothing" and "comfort" concepts. The mild taste does not require heavy masking.

Frequently Asked Questions
Q: What is the difference between Ulmus pumila and Ulmus rubra?
A: They are different species. Ulmus rubra (slippery elm) is native to North America. Ulmus pumila L. (Siberian elm) grows across Central Asia, Siberia, and northern China. Both contain mucilage in their inner bark. Our product uses Ulmus pumila L. as the raw material.
Q: Is your Elm bark extract powder water-soluble?
A: Partially. The mucilage polysaccharides hydrate and swell in water, creating a viscous dispersion. It does not form a clear solution. The powder disperses well in warm water with stirring.
Q: What is the typical usage level in capsules?
A: Most customers use 200–500 mg per capsule of the 10:1 extract. This delivers a meaningful mucilage dose while keeping the capsule size manageable.
Q: Can you provide samples for formulation trials?
A: Yes. We send 50–100 g samples with the relevant COA for your evaluation. The sample is free; you cover shipping.
Q: Does the extract contain any carriers or excipients?
A: No. Our standard production is straight extract powder with no added carriers.
Q: What certifications do you hold?
A: Our facility operates under GMP. We can arrange Halal, Kosher, and Organic certification upon request for specific orders.
