Thickener DP-325 is a thickener and emulsifier which can emulsify oils in water and produce thick and stable emulsions for cosmetic applications with creamy and glide-on feel to meet the needs of most demanding formulations at low use level. It is a ready-to-use liquid copolymer (INCI name: Hydroxyethyl Acrylate/Sodium Acryloyldimethyltaurate Copolymer and Isoparaffin and Polysorbate 80) and is also developed for water based polymer products and polar organic solvents such as ethylene glycol, propylene glycol and glycerol.  This product provides remarkable thickening power between pH 2 and pH 12, very good mechanical stability and electrolyte resistance and is especially suitable for product systems which poly-acrylic acid thickeners are not capable for the application requirements. The product can be used directly at room temperature and does not require the addition of ammonia or other alkali to the system.

Thickener DP-325 has the following benefits:

1. Extremely easy to use and highly efficient
2. Very stable emulsion for long-term uniform quality
3. Excellent emulsifier for all types of oily phases
4. Effective over a wide pH range

Typical Physical Properties

1. Appearance: Creamy liquid
2. Solids: 47 ± 1.0%
3. pH: 7.5 ± 1.0
4. Specific gravity: 1.22
5. Viscosity: around 100,000 cps (Brookfield RVT, #6, 5 rpm)

Method of Use and Example
Water or solvent is added to the pre-weighed Thickener DP-325 with or without oil phase with gentle agitation until a smooth and homogeneous gel is formed. The results of three examples are shown in the following table:

Sample	Viscosity (Brookfield RVT,#6, 5rpm)
2% DP-325 , 98% DI water	60,000 cps
2% DP-325 , 98% propylene glycol	31,000 cps
2% DP-325, 15% 2-ethylhexyl palmitate, 83% DI water	58,200 cps

These examples are for reference. The formulation should be adjusted to the product requirement.
