Uses 

COSCARE® PO is an anti-dandruff agent and a broad-spectrum antimicrobial agent, suitable for antidandruff shampoos and hair care products such as hair tonics and cream rinses with an antidandruff  action. It is very effective for preservation of a wide range of cosmetics and toiletries.

Solubility 

Generally, the solubility of COSCARE® PO is highly depending on the pH value of the solution. As a rule  of thumb, it is better dissolved in neutral and slightly alkaline aqueous solutions than in acidic solutions.  It is possible to dissolve between pH values from 5 to 8 in surfactant solutions and alcohol/water  mixtures.

Light stability 

COSCARE® PO is sensitive towards UV light and might be decomposed depending on the amount of  irradiation. Therefore, it is recommended to use non-transparent or colored packaging, ideally the original packaging. 

Compatibility with cosmetic raw materials 

COSCARE® PO is compatible with most surfactants, additives and active ingredients used in cosmetics.  Compatibility with perfume oils with aldehyde and ketone functionality may be limited in some cases.  Despite the anionic character of the active ingredient molecule, COSCARE® PO can be used together with  most cationic surfactants (quaternary ammonium compounds) and cationic active ingredients and in some  cases, the solubility of COSCARE® PO in water is increased. Nevertheless, it is advisable to carry out  compatibility and stability tests when using these substances. Attention must be drawn to the product’s  property of forming complexes with metal ions, especially iron and copper ions.

Influence on viscosity in surfactant systems 

In some surfactant systems, COSCARE® PO may cause an increase in viscosity which can be considered  in order to economize on consistency modifiers during formulation development.
