Bulk Betulin Supplier (CAS 473-98-3) – ≥98% HPLC, EU Supply
NST-03-001 is a purified betulin ingredient derived from Betula platyphylla Suk. bark. Supplied as a fine white powder with an assay of at least 98.0% on a dry basis, it is intended for cosmetic and personal-care formulation development, particularly oil-rich, anhydrous and delivery-system-enabled products.
Who This Product Is For
| Customer type | Typical requirement |
|---|---|
| Skincare and personal-care manufacturers | Purified birch-bark-derived skin-conditioning ingredient for creams, balms and oleogels |
| Contract manufacturers | Defined identity, assay, particle and contaminant specifications for formulation projects |
| Cosmetic R&D and formulation teams | Betulin powder for oil-phase dispersions, structured systems and validated carriers |
| Specialty ingredient distributors | Specified betulin for supply to cosmetic manufacturers and formulators |

Technical & Formulation Considerations
| Consideration | Formulation relevance |
|---|---|
| Water solubility | Betulin is poorly soluble in water and is not suited to direct incorporation as a clear aqueous solution without a separately validated solubilization or delivery system. |
| Preferred formulation architecture | Most relevant to anhydrous, oil-rich and water-in-oil systems, or to oil-in-water products using a validated carrier. |
| Particle behavior | Wetting, deagglomeration and crystal behavior can affect skin feel, sedimentation, homogeneity and emulsion stability. The supplied mesh specification does not define a micron-scale particle-size distribution. |
| Rheology | Dispersed betulin may influence viscosity, thixotropy and oil-phase structure. Performance should be verified in the complete formulation. |
| Finished-product validation | Evaluate compatibility, crystal growth, phase stability, viscosity drift and sensory properties under the intended manufacturing and storage conditions. |
Applications
| Application | Commercial role |
|---|---|
| Anhydrous balms and oleogels | Skin-conditioning ingredient in oil-rich, structured topical products |
| Water-in-oil face, hand and body creams | Dispersed skin-conditioning ingredient with formulation-dependent effects on structure and rheology |
| Carrier-enabled oil-in-water creams | Incorporation into lighter emulsions through a separately developed and validated delivery system |
| Specialty skincare formulations | Birch-bark-derived purified ingredient for products targeting dry or environmentally stressed skin appearance, subject to finished-product substantiation |
