Sioris My Soft Grain Scrub

Direct research on this extract is limited and mostly comes from supplier safety dossiers:

Human testing found it to be non-irritating or sensitizing in a 50-subject occlusive patch test.

Real-world concentrations are very low: industry survey data puts it at 0.0007% to 0.02% in face and neck products, 0.0005% in moisturizers and cleansers, and up to 0.04% in hair conditioners.

Most human clinical skin research on coconut is on virgin coconut oil and not this extract. For example, a randomized double-blind trial found virgin coconut oil as effective and safe as mineral oil for mild to moderate xerosis with significant improvement in hydration and skin surface lipids. However, you can't transfer that to a water-based fruit extract at 0.01%.

There's no comedogenicity data for this specific ingredient; the "coconut clogs pores" reputation comes from coconut oil which scored high on the old rabbit ear assay.

That method tested pure ingredients on rabbit ears and later work showed the results translate inconsistently to human skin.

Some people still find it breaks them out. So if that's you, definitely trust your skin.

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations.

Typical use levels in a formula run about 1-5%.
