ASPERGILLUS/SACCHAROMYCES/HONEY/ORIGANUM MAJORANA LEAF/RICE FERMENT LEES EXTRACT.

Valuable / HAIR CONDITIONING, HUMECTANT, SKIN CONDITIONING

A sophisticated bio-fermented complex that integrates the humectant properties of honey with the regenerative potential of marjoram and upcycled rice lees. This multi-tasking extract provides a dual-action approach to skin health, combining non-irritating enzymatic exfoliation with deep-stratum moisture replenishment.

Science

Through a dual-fungal fermentation process using Aspergillus and Saccharomyces, complex macromolecules from honey and botanicals are broken down into low-molecular-weight amino acids and organic acids. These small-form metabolites penetrate the stratum corneum to accelerate natural keratolysis (cell turnover) without the irritation associated with acids. Simultaneously, the Origanum Majorana component stimulates hyaluronic acid synthesis, while the rice ferment lees provide phenolic antioxidants to protect the skin matrix and enhance the Natural Moisturizing Factor (NMF).

This complex is frequently used in 'claim' amounts below 1.0% to market the presence of fermented ingredients. However, the data suggests that a minimum threshold of 1% is required to achieve functional 'moisturizing keratin care' and measurable barrier enhancement.

Stability

The extract remains highly stable in aqueous systems but is thermolabile; it must be incorporated during the cooling phase (below 40°C) to prevent the degradation of fermented metabolites.

Synergies

  • Hyaluronic Acid
  • Niacinamide
  • Panthenol

Conflicts

  • Strong oxidizing agents
  • Extreme pH environments (<3.5 or >8.0)

Safety

Not reviewed
Pregnancy
Safe
Sensitization risk Low

While the specific fermented complex is awaiting CIR review, the constituent components—Honey, Marjoram, and Rice Ferment—have long-standing safety profiles in cosmetics and are recognized by the EU Cosmetic Ingredient Glossary.
