nature enables the absorption of water through its capillary system, while their physical structure allows dispersion within oil phases. This dual compatibility contributes to their
versatility across emulsions, anhydrous systems and powder formulations.
Functional mechanism The multifunctionality of cellulose fibres is based on several mechanisms.
Capillary absorption The porous structure enables retention of moisture and lipids through capillary forces. This is particularly relevant in deodorant and skin care applications.
Light scattering Irregular fibre surfaces diffuse incident light, producing soft-focus effects that improve visual appearance of the skin.
Mechanical structuring Fibres form three-dimensional networks within formulations, influencing rheology, stability and texture.
Functional interaction Controlled fibre morphology allows mild exfoliation without sharp edges associated with conventional scrub particles. These mechanisms enable cellulose fibres
to replace multiple functional ingredients simultaneously, supporting simplified and more sustainable formulations.5
Moisture management and sensory enhancement in deodorants Moisture control remains a primary function of deodorant products. Conventional absorbents, including talc and inorganic powders, may provide effective moisture uptake but often compromise sensory attributes. Bamboo cellulose fibres offer a different
approach based on their internal capillary structure. The network of microvoids within the fibres allows efficient absorption and temporary retention of sweat. This results in reduced perception of wetness,
improved dryness over extended periods and enhanced comfort during daily use.
Sensory impact Beyond functional performance, sensory perception plays a crucial role in consumer acceptance. Cellulose fibres contribute to a distinct tactile profile characterized by: ■ soft and velvety skin feeling ■ reduced stickiness after application ■ improved glide during spreading The flexible nature of the fibres prevents the
formation of a rigid or powdery film, resulting in a more natural skin finish.
Microplastics-free texturizing and optical effects Synthetic polymer powders such as PMMA and Nylon-12 are commonly used to provide soft- focus effects and improve texture.1,2

persistence in the environment, interest in natural alternatives has increased. Bamboo cellulose fibres provide comparable
performance through physical mechanism rather than engineered spherical particles. Low dosages of these fibres already create a
considerable mattifying effect and enable a quick skin absorption in liquid make-ups or foundations. A micro fine bamboo powder with high capacity to bind oil and water enables a clear and quick mattifying effect. Besides a smooth and even skin surface, sensory as well as texture are considerably improved. In addition it creates a silicone touch on a natural basis.
Optical performance The fibrous structure scatters light across the skin surface, resulting in reduced appearance of fine lines, blurring of skin imperfections and improved complexion uniformity.

Sensory benefits Cellulose fibres improve the tactile profile of formulations by reducing oily or greasy perception, enhancing spreadability during application and providing a smooth after-feeling. These combined effects enable formulators to
absorption smooth
achieve high-performance results while eliminating synthetic ingredients. Unlike spherical microplastics, fibres provide a more natural tactile perception.5
Texture optimization in emulsions and solid formulations One of the most significant advantages of fine cellulose fibres lies in their ability to modify texture in complex formulations.
Lightening of water-in-oil emulsions Formulators usually face huge challenges by turning oily or tacky water-in-oil (W/O) basis emulsions into formulations with soft and powdery textures or to ensure a non-greasy and smooth skin feeling by quick absorption. Water-in-oil (W/O) body lotions are often
associated with a heavy and occlusive skin feeling. This perception is primarily driven by the continuous oil phase and high lipid content. The incorporation of cellulose fibres alters
the internal structure of the emulsion. Fibres distribute within the oil phase and create a three-dimensional network that improves phase organization. This leads to reduced perceived heaviness, improved distribution of oils on the skin, and
