Product Description
White willow bark extract is standardized to salicin from willow bark or branch. Grades run from about 15% (tan powder) to 98% (near-white).
Salicin is the marker used in botanical analgesic-style supplements and in some clarifying or scalp formulas. It is not salicylic acid, and a cosmetic claim written for the acid does not transfer.
When buying, name the salicin percent, the plant part, and whether the use is oral or topical. HPLC is the usual assay.

Applications
Clarifying Cleansers
A botanical candidate, not a salicylic-acid active. Run irritation and pH on the finished cleanser.
Scalp Cleansers
Screen colour and residue in the surfactant base before a claim.
Tablets
Higher salicin grades are paler and easier to hide in a white tablet.
Oral or Topical
Say which. A cleanser spec and a capsule spec are not the same salicin percent.
Bark Teas
A tea cut is not a 50% or 98% salicin extract. Match the form to the label claim.
FAQ
Is salicin the same thing as salicylic acid?
No. Do not label the extract as the acid.
Why do the powders range from brown to nearly white?
Lower salicin grades stay brown-yellow; high-assay grades are paler.
What is the CAS number for salicin?
Salicin is CAS 138-52-3.
Which salicin grades are available?
About 15%, 25%, 50% and 98%.
Which part of the willow is used?
Bark or branch. The batch should say which.
How is the salicin assay done?
HPLC. Do not accept a willow-bark ratio in place of a salicin percent.
