Question

Are there any ingredients that can help reduce the odor of glutathione?

Answer

For reducing the natural odor of glutathione in a cosmetic formula, the most directly matched catalog option is Odor-Kill™.

Recommended options from the catalog:

Option When to use Usage guidance Notes
Odor-Kill™ Best first choice when the formula already uses glutathione powder and the odor needs to be reduced Catalog recommends 0.3-1%, commonly 0.3-0.5% for odor reduction; product spec allows up to 3% Product description specifically states it is effective for sulfite-type odor and is suitable for formulas where glutathione odor is a problem. Add in the final step and avoid heat above 50°C.
L-Glutathione Liquid (Deodorized, Colorless) If you can switch from powder glutathione to a lower-odor glutathione form Use according to the formula target; catalog spec lists best use around 5% This is glutathione already processed to reduce odor, easier to add into water-based formulas. Keep pH 3-6 and avoid heat above 40°C.
CycloSorb™ Clear / CycloSorb™ Cream Possible odor absorber support, especially if the formula format suits cyclodextrin 2.5-5% Clear is water-soluble; Cream is non-water-soluble/dispersible. Avoid using with fragrance-heavy formulas because cyclodextrin may absorb fragrance too.

I would start with Odor-Kill™ 0.3-0.5% first, then adjust if the odor is still noticeable. If you have not fixed the glutathione form yet, using L-Glutathione Liquid (Deodorized, Colorless) instead of regular glutathione powder is usually the cleaner option.

Keep the glutathione formula condition in the proper range: mix into the water phase, avoid high heat, keep pH about 3-6, and store away from heat/light/air. Zinc Ricinoleate products are deodorant actives, but their catalog pH range is mostly around neutral to alkaline, so they are not my first choice for a low-pH glutathione whitening formula unless the final formula pH is compatible.
