    Easy-to-use form

    KY-MF-1 is supplied as a low viscosity liquid, which is easily and quickly incorporated.

    Suspension and stabilization

    KY-MF-1 was developed to function with surfactants and surfactant blends to provide

    significant suspending and stabilizing properties to formulations, insoluble and difficult-to-stabilize ingredients, such as silicones, Can be co-emulsified and stabilized. Excellent suspension and stabilization properties are present even on low viscosity formulations.

    Thickening and flow control

    KY-MF-1 thickens shampoo, body wash and other cleansing formulation to their ideal viscosity and provides highly desirable flow characteristics, although it has lower viscosity in water, KY-MF-1 works better synergistically with surfactants and salts to provide options for achieving various suspending, stabilizing, and thickening requirements.

    Follow is the example of viscosity:

       Formulation:                         % (w/w)

        SLES 70                               10.0

        Cocamide DEA                      1.7

        Cocamodopropyl Betaine        5.8

        MF-1 / KY-MF-1                     7.0               

        Use KOH to adjust pH = 7.0

    Viscosity of the above formula with:

    KY-MF-1                          8600cps

    MF-1                               800cps

    Clear formulation

    KY-MF-1 enables the formulation of highly transparent shampoo and body washes at pH = 7. Compare with MF-1, KY-MF-1 can add a little more salts for clear formulations.

    Excellent compatibility

    KY-MF-1 is compatible with virtually all commercial nonionic, anionic and amphoteric.

    surfactants as well as a wide array of popular additives and conditional agents, such as cationic polymer.

    Synergistic Thickening with Salt

    KY-MF-1 works synergistic with low level of salt to increase suspension and viscosity when the polymer is formulated with surfactants.

    Storage Period

    As we known, the storage period of MF-1 is only 9 months; this period is too short for transportation and storage, if overtime. The suspension ability decrease rapidly, but its appearance and specification will not change, for this, we can test it in lab, we put KY-MF-1 and MF-1 in 48oC oven, after one month, get out to use in formulation to check its suspension ability.

      For suspension ability of:

    KY-MF-1                 No change

    MF-1                    Decrease

    Enhanced Pearlization

    KY-MF-1 has the remarkable ability to enhance the visual impact mica and other pearlizing additive used surfactant-based systems, the stability of the visual impact is also dramatically improved.

    Higher pH

    KY-MF-1 has higher pH = 5, it is more safety for use of worker and equipments, without effect to other performance.

    ● Product Chemistry

    KY-MF-1 is an alkali swellable acrylic emulsion polymer, as supplied, the majority of the polymer’s carboxyl functionality is in the protonated form, the polymer molecules are coiled and impart little suspension and viscosity to the liquid, upon neutralization, the molecule ionize, expand due to charge repulsion of the anionic carboxylated and provide suspending and thickening properties

    to the aqueous system in which they reside, The mechanism is known as “hydrodynamic” thickening, in hydrodynamic theory system, it is the physical packing of polymer molecules (and possibly other formula ingredients) that is responsible for the development of suspending ability and viscosity. This “space filling” mechanism is distinctly different from the associative thickening mechanism attributed to hydrophobically modify polymeric rheology modifiers.

    ● Performance properties

    KY-MF-1 was designed to be used in surfactant containing systems; it is in the presence of surfactants that polymer displays its most valuable performance attributes:

    ü  Synergistic suspending, stabilizing, and thickening with surfactant and salts.

    ü  Low pH suspending, stabilizing, and thickening.

    ü  High clarity.

    ü  Enhancement of pearlization.

    Viscosity in surfactants

    For the difference with MF-1, in the water, KY-MF-1 has lower viscosity, but in surfactant it displays better synergistic properties, in same formula, it has better viscosity, more surfactant, salt, and polymer itself rapidly increase viscosity, if the pH increase, the viscosity also increase:


       Name                  % (w/w)

       Water                  93

       KY-MF-1               7

    Use KOH adjusts pH = 7.5, viscosity only 3500Cp, but another example:
       Name                  % (w/w)

       Water                   89

       SLES 70%             4

       KY-MF-1                7

    Use KOH adjust pH = 7.5, the viscosity achieve 8500cps.

    suspending in surfactants;

    The suspending ability of KY-MF-1 is very significant in surfactant-based formulation, many type of insoluble ingredients are easily suspended and stabilized including:

     Gelatin-based and other beads and capsules
    Walnut shell

    Compare with MF-1, KY-MF-1 use same quantity of MF-1 and adjust same viscosity, we get the same suspending ability for all kind of insoluble ingredients,

    Another important problem, the pH would effect its suspending ability, if pH increase, its suspending decrease, when pH = 6.2, we can get the best suspending ability, we suggest that the pH should be lower than pH ≤ 8.0 for suspension.

    pH: “Back-Acid” Thickening

    The KY-MF-1 is not necessary to use this process.


    The follow general guidelines should be observed:

    1). Add primary anionic and nonionic surfactant, for example: Sodium Lauryl Sulfate, Soidum Lauryl Ether Sulfates.

    2).  Add remaining surfactants, for example: Amphoterics.

    3)  Add conditioning and ancillary ingredients, for example: silicones, cationics, EDTA.

    4)  If desired, add pearlizing agent, for example: mica, EGDS, EGMS.

    5)  Add KY-MF-1 (first mix with water KY-MF-1 ÷ water = 1÷1)

    6).  Neutralize pH = 6.5 to 7.5 with TEA or KOH or citric acid.

    7)   Add fragrance, dyes and preservatives.

    8)  If desired, add sodium chloride or CAB-35 to further increase viscosity.

    We suggest adding KY-MF-1 in the last, before neutralize, fragrance, dyes, preservatives, and viscosity adjusted.
