Question 1

What does Saccharomyces/Rice Ferment Filtrate do in a cosmetic formula?

Accepted Answer

This ingredient is used mainly as a skin-conditioning and humectant adjunct, adding light hydration and supporting a smoother feel in watery serums, essences, lotions, and masks.

Question 2

Is Saccharomyces/Rice Ferment Filtrate clean?

Accepted Answer

From a clean-beauty perspective, it is generally well accepted because it is water-based, low in irritation potential, and not a typical restricted-list ingredient. The main review point is the full preservation system, since this type of material can add nutrients that require good microbial control.

Question 3

Is Saccharomyces/Rice Ferment Filtrate sustainable?

Accepted Answer

This ingredient is made through microbial processing of a cereal substrate, which generally fits a lower-impact, renewable-feedstock profile. It is expected to be readily biodegradable, although overall footprint depends on agricultural sourcing, water use, and fermentation controls.

Question 4

Is Saccharomyces/Rice Ferment Filtrate COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic formulas when produced with approved substrates, processing aids, and preservatives. Its fit with Green Chemistry is favorable because fermentation uses renewable feedstocks and water-based processing, with relatively benign end-of-life behavior.

Question 5

How does Saccharomyces/Rice Ferment Filtrate work chemically?

Accepted Answer

This material is an aqueous liquid fraction from a fermentation broth, so its profile is a dilute mix of amino acids, peptides, sugars, minerals, organic acids, and small fermentation metabolites rather than one defined molecule. It is commonly used at low single-digit percentages, performs best in water-phase systems, and needs preservation and batch quality checks because composition can vary by supplier and process.
