COMPATIBILITY
SP M-550 is compatible with all types of surfactants. Its compatibility depends on the chemistry of the anionic material. The maximum quantity of active cationic polymer which can be incorporated into an anionic solution without causing any haziness is calculated by the ratio r:

r = Active Anionic Material/ Active Cationic Material
Sodium Laureth Sulfate r < 12 Triethanolamine Lauryl Sulfate r < 8

COSMETIC APPLICATIONS
Clear and colourless cosmetic products
Ease of incorporation in formulations due to complete water solubility
Improved foam stability
Total compatibility with non-ionic and amphoteric materials

SP M-550 is a cationic polymer which forms an electrostatic combination with the negatively charged keratin.

In hair care products, SP M-550 can: reduce static and flyaway improve wet and dry combability increase shine, softness and body

In skin care products, SP M-550: improves the spreadability and the application of the product gives the skin a soft, velvety and non greasy afterfeel

CONCENTRATION USE
SP M-550 should be used at concentrations from 0.2% to 5% depending on the required effect. It should be added in the aqueous phase under agitation.
