INCI: Sassafras Officinale Bark/Root Extract

Sassafras extract is a traditional botanical with potential skin benefits, but its use is limited by safety concerns related to the compound safrole, which is restricted in many countries.

In plain English

Sassafras extract comes from the bark and root of the sassafras tree. It has a pleasant, root beer-like scent and was once used in skincare for its astringent (tightening) and soothing properties. However, the extract contains a compound called safrole, which has raised safety concerns. Today, most cosmetic products use safrole-free versions or avoid it altogether. If you see it on a label, it's likely in very small amounts for fragrance.

What it is

Sassafras Officinale Bark/Root Extract is a natural plant extract obtained from the bark and roots of the sassafras tree (Sassafras albidum). It contains volatile oils, including safrole, which gives it a characteristic scent.

How it works

In cosmetic products, sassafras extract is primarily used as a fragrance ingredient due to its pleasant, spicy-sweet aroma. It may also have mild astringent properties, meaning it can temporarily tighten the skin's surface, but this effect is weak and not well-documented in modern formulations.

Pros

Natural fragrance

Provides a unique, pleasant scent that many find appealing, without synthetic perfumes.

Traditional use

Has a history of use in herbal skincare for its mild astringent properties, which may help temporarily tighten pores.

Cons and cautions

Safety restrictions

Safrole, a natural component, is restricted or banned in many countries due to potential health risks, limiting its use in modern cosmetics.

Limited efficacy

The astringent effect is mild and not well-supported by modern research; other ingredients offer more reliable benefits.

Best for

  • Those who enjoy natural, herbal-scented products (if safrole-free)
  • People with oily skin looking for mild astringent effects

Use caution if

  • Anyone with sensitive or reactive skin, as the extract may cause irritation
  • Pregnant or nursing individuals, due to safrole concerns

Usage tips

Check the label for 'safrole-free' versions if you want to avoid the compound.
Use products with sassafras extract only as directed; avoid ingesting or applying to broken skin.
Patch test first if you have sensitive skin, as the extract can be irritating.

Safety summary

Sassafras extract is generally considered safe in very low concentrations for topical use, but the presence of safrole raises concerns. Regulatory bodies restrict safrole levels, so most commercial products are safe. However, individuals with sensitive skin or those who are pregnant may want to avoid it.

Research notes

Research on sassafras extract in cosmetics is limited. Most studies focus on safrole's toxicity rather than skin benefits. The extract's astringent and fragrance properties are based on traditional use rather than strong clinical evidence.

Common label clues

Typical concentration
Very low (typically under 1%) due to safety concerns
Regulatory status
Safrole, a key component of sassafras extract, is restricted in cosmetics by the EU and FDA due to potential carcinogenicity. Many products use safrole-free extracts or avoid the ingredient entirely.
Common uses
Fragranced products, Traditional herbal preparations
Environmental note
Sassafras trees are native to North America and are not considered endangered, but overharvesting for essential oils can impact local ecosystems.

Good to know

  • Sassafras extract is often found in natural or 'herbal' skincare lines, but its use has declined due to regulatory concerns.
  • The FDA has banned safrole as a food additive, but it may still appear in trace amounts in cosmetics.
