INCI: Ammonium Acryloyldimethyltaurate/VP Copolymer

Solubility: Water dispersible (hydrates smoothly in water without heating) Can also be dispersed in oil with or without heating.

Use rate: 0.5 – 2.0%

pH (1% in solution): 4.0 – 6.0

pH Stability: 4.0 – 9.0 (Aristoflex® AVC is an ammonium salt, pH higher than 9.0 will release ammonia).

Temperature tolerance: Avoid heating above 80°C

Shear Tolerance: Tolerates high-shear stress

Appearance: White powder

Shelf life: 3 years

Other Particulars: Not suitable for electrolyte-containing formulas: Avoid surfactants with salts, and hydrolyzed proteins.

TECHNICAL TIP

Clear Gel Processing:

Method I

(A) Combine all ingredients except Aristoflex AVC and mix until clear (Heat if necessary and cool to 35ºC).

(B) Add Aristoflex AVC and mix until a smooth gel is obtained.

Method II

(A) Add Aristoflex AVC to water; mix until fully hydrated and clear.

(B) Add remaining ingredients one at a time and mix until a smooth gel is obtained.

Emulsion Processing:

Aristoflex® AVC can be used to prepare O/W emulsions in both hot and cold processes.

Method I (Preferred)

(A) Disperse Aristoflex AVC in the oil phase with the emulsifier (if using an additional emulsifier).

(B) Combine oil and water phases, and mix until homogeneous.

Note: Oil phase mixing vessel should be free of moisture to avoid premature hydration of polymer and creation of gel particles.

Method II

(A) Prepare emulsion as normal.

(B) Post-add Aristoflex AVC (dry powder or as aqueous gel premix) to the emulsion (can be added immediately, or after an initial mixing period, as desired).

Method III

(A) Combine oil and emulsifier in one phase.

(B) Add Aristoflex AVC to the water phase, mixing until a homogeneous gel is formed.

(C) Add (A) to (B)

Note: Although Method I is preferred; the optimum method of processing is formulation-dependent and varies with processing equipment. For Method III, sweep mixing may be required depending on viscosity of aqueous phase. Emulsions may be homogenized if necessary but is not routinely required.
