Description

Pre - neutralized Carbomer

PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt

It is a pre - neutralized synthetic polymer that can be used as a thickener, suspending agent and stabilizer in most cosmetic products.

The use of pre - neutralized carbomers provides several advantages:

- excellent handling (low powder);

- fast dispersion;

- simplification of the production process (elimination of the neutralization phase)

- constant pH value throughout the entire production process

- the ability to change the viscosity of the finished product

Pre - neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt)  dispersions are characterized by high viscosity and clarity (in the photo there is a finished gel with an input of 0.3% ).

 Usage  Pre - neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt) 

Unlike traditional carbomers, Preneutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt) does not require any preliminary dispersion and thickens as soon as water or water / alcohol mixture (up to 70: 30) gets on it and gives a viscous gel (we recommend to "soak" the product for a while in water, so that the polymer can be completely saturated with water).

The stirring method and stirring speed are different from those used to disperse the polymer acid. The best way to work with Pre - Neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt)  is to use the equipment normally used in the neutralizing phase of the carbomer (anchor type). Slow addition of the powder prevents lump formation and ensures fast thickening. During the preparation of the emulsion, PNC 400 can be dispersed in oil or in the aqueous phase before emulsification, or sprinkled directly into the emulsion, stirring until a homogeneous system is obtained (it is better to pre - dissolve and then add to avoid polymer lumps in the finished product).

pH (0.5% in water) Pre - neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt)  is about 7. Low pH requires little adjustment, possibly adding acid (eg HCl, H3PO4, citric and lactic acid). high amounts of acid should be avoided due to the formation of salt, which affects the viscosity over a wide range.

When a strong pH drop is necessary, the use of a mixture of Pre - Neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt)  and the corresponding polymer acid (i. e. Synthalen K) provides good viscosity over a wide pH range without using any neutralizing agent. Under normal conditions, gels prepared from Predneutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt)  neither prevent nor promote the growth of microorganisms; therefore the addition of a suitable preservative system is advisable. Ultraviolet rays can cause loss of viscosity in gels based on Pre - neutralized Carbomer (PNC400, Sodium Carbomer, Carboxyvinyl polymer sodium salt). . . The addition of water - soluble UV absorbers such as UVASORB S5 (benzophenone - 4) can help prevent polymer degradation.
