Betafib® MCF

Structuring numerous applications with Betafib® MCF,
our novel and patented natural rheology modifier


Particle carrying properties under challenging conditions
Typically, the main reason to investigate the possible use of Betafib® MCF originates in the particle carrying properties of this unique material whilst remaining the property to form a gel with shear-thinning character. Unique since it forms a physical network in a fluid. The physical presence of the Betafib® material results in the capacity to carry (also large amounts of) particles. These particles can be of all sorts and sizes; even the capability to carry nylon bearings in a watery fluid was demonstrated. Due to the inert nature of cellulose and as an outcome of the Cosun patented processing route, Betafib® MCF upholds its performance in various formulations and under challenging conditions.
What is typically seen upon adding Betafib to a fluid? See the figure below where the effect of structuring with Betafib is shown for dandruff shampoo by rheological measurement.


Earlier testing indicated the versatility of Betafib. In a variety of formulations, many ingredients are being used: all kinds of surfactants, actives and particles. Various formulations offer a broad pH range where some of those are heavily charged. Nevertheless Betafib® MCF was incorporated in all of them without too much of a hassle. Therefore it feels just to state that this exceptional structurant is highly compatible for use in the categories tested. The test panel judged the skin feel of personal care products containing Betafib® MCF as positive. Formulations containing the fibre/platelet structurant showed to be very well applicable i.e. easily to distribute during application. The test panel was also very pleased with the organoleptic properties of the skin care formulations. Due to the rheology that Betafib® MCF offers, with particle carrying properties at low/no shear conditions whilst remaining its shear thinning character, the ease of dosing and ease of use were rated as good for the formulations tested. Typical levels of usage range from approx. 0.15 to 1.0% as expressed in 100% dry matter on the total mass of the formulation being structured.
