The 2026 personal care landscape is rapidly reshaping around fermented bioactives. Postbiotics, exosome ferments, and advanced peptides now share the spotlight with a quieter but equally consequential category, fermented polysaccharides. Natori Pullulan 90 sits at the center of this movement, a high purity biopolymer produced through controlled fermentation of Aureobasidium pullulans, engineered for cosmetic performance.
Unlike conventional thickeners or simple humectants, Natori Pullulan 90 acts simultaneously as a film former, a moisture reservoir, an antioxidant support agent, and a carrier matrix for sensitive active ingredients. This multifunctional profile makes it one of the most flexible workhorse ingredients available to formulators developing serums, masks, sun care, and clean label skincare for 2026 and beyond.
Fermented Polysaccharide Technology Behind Natori Pullulan 90
Pullulan is a linear polysaccharide composed of maltotriose units linked by alpha 1,6 glycosidic bonds. The unique sequence of alpha 1,4 and alpha 1,6 linkages gives the polymer a distinctive flexibility, water solubility, and oxygen impermeability that synthetic polymers struggle to match.
Natori Pullulan 90 is produced through precision controlled fermentation, followed by purification stages that remove residual proteins, salts, and pigments. The result is a high purity, neutral, cosmetically refined polysaccharide that performs reliably across a wide pH range. Its non ionic nature makes it compatible with cationic, anionic, and non ionic systems alike, which is rare for a high performance film former.
Multifunctional Performance in Cosmetic Formulations
Formulators are under pressure to consolidate ingredient lists while elevating performance claims. Natori Pullulan 90 supports this trend by delivering several functional benefits from a single ingredient.
On application, it forms a soft, transparent, breathable film that visibly tightens the skin surface and gives an immediate sensorial smoothness. Hydration is sustained through the polymer’s strong water binding capacity, creating a soft moisture cushion that does not feel occlusive or heavy. The fermented origin also brings inherent antioxidant supportive properties, contributing to skin defense formulations without the need for additional radical scavenging actives.
Beyond standalone performance, Natori Pullulan 90 functions as a delivery scaffold. Sensitive ingredients such as vitamin C derivatives, peptides, and plant extracts can be stabilized within the polysaccharide matrix, extending their functional lifespan in the final product.
Sensory, Stability, and Format Versatility
Sensorial expectations have shifted dramatically. Consumers want featherlight serums, second skin masks, and sunscreens that feel like skincare rather than barriers. Natori Pullulan 90 supports this sensory direction with low intrinsic viscosity and a smooth, non tacky finish that disappears quickly into the skin.
Its thermal stability allows incorporation in both hot and cold processes, simplifying manufacturing for emulsions, gels, and water based systems. The polymer remains stable across a broad pH window and tolerates common cosmetic preservatives, emulsifiers, and electrolytes. This stability profile reduces formulation risk and supports longer shelf life, both of which matter for brands operating across multiple climate zones.
Clean Label, Microbiome Friendly, and Future Ready Positioning
Clean beauty has matured from a marketing label into a structural requirement. Brands now need ingredients that are naturally derived, microbiome friendly, and traceable to a defined biotechnology source. Natori Pullulan 90 satisfies all three. It is fermented from a single microbial strain, free from animal derived material, and gentle to the skin’s resident microflora.
For formulators developing claims around fermented skincare, biotech beauty, postbiotic adjacent technologies, or sensitive skin care, Natori Pullulan 90 supplies a credible, scientifically anchored backbone. Its compatibility with peptides, exosome based actives, and humectant complexes makes it a natural fit for hybrid formulations that combine multiple modern ingredient categories.
