Zinc Pyrithione

Description

What is Zinc Pyrithione?

Zinc Pyrithione is a cosmetic ingredient primarily in anti-dandruff shampoos and scalp cleansers. It inhibits the fungi and bacteria that typically cause flakes, itching, and scalp irritation. It’s most commonly found in rinse-off hair products and is a well-known anti-dandruff active.

Why You Should Use Zinc Pyrithione

Helps Control Dandruff

Zinc Pyrithione helps to control the flakes and itching associated with dandruff. It is a scalp care active included in finished anti-dandruff products.

Good Fit for Shampoo Systems

It is extensively used in shampoos and scalp washes. A published anti-dandruff shampoo formula combines Zinc Pyrithione with a surfactant system, stabilized suspension, and a scalp-compatible pH.

Works at Practical Use Levels

Ready-to-use products on the market typically contain Zinc Pyrithione at 0.5% to 1%, depending on the objective of the formula. It is useful for a standard anti-dandruff shampoo as well as a more intense scalp product.

Useful for Scalp-Focused Product Lines

It is used for formulating for flaky scalp, itchy scalp, and scalp cleaning. It is particularly useful for a rinse-off anti-dandruff product.

How to Use

Handling Note:

Make sure to use a uniform material. Take care to mix slowly. If you buy a suspension grade, attempt to make sure the active is well dispersed. In one published shampoo formula, Zinc Pyrithione is kept in suspension by a rheology system, and the provider’s note says to keep the material uniform before use.

Use Levels by Product Category

Usage levels vary with the strength of the grade purchased. The table below is in terms of active Zinc Pyrithione in the finished product. This is in line with common anti-dandruff product concentrations and hair use as rinse-off products.

Target pH:

For most rinse-off scalp products, the pH should be in the range of 5.5 to 6.5. One published Zinc Pyrithione anti-dandruff shampoo has a pH of 5.8 to 6.2.
