CONDICARE PQ-7 is a highly charged cationic co-polymer that provides clarity and compatibility to anionic systems. 
This co-polymer is highly water soluble and is ideal for use in hair and skin care applications.

CONDICARE PQ-7 contains positively charged quaternary ammonium groups along a water-soluble polymer backbone.
These cationic sites strongly attract and bind to the negatively charged surfaces of hair and skin.
This electrostatic interaction is responsible for its substantivity and long-lasting conditioning effect.

CONDICARE PQ-7 is typically a clear to slightly hazy, colorless to pale yellow viscous liquid.
It is fully soluble in water and easily incorporated into cold or hot process formulations.
CONDICARE PQ-7 remains stable over a wide pH range commonly used in shampoos and cleansers.

In formulations, CONDICARE PQ-7 deposits onto hair fibers and skin during rinsing due to electrostatic attraction.
It forms a thin, flexible conditioning film that reduces friction and improves surface smoothness.
This leads to easier combing, reduced static electricity, and improved softness.

It is widely used in shampoos, 2-in-1 shampoo-conditioners, body washes, facial cleansers, and liquid soaps.
CONDICARE PQ-7 improves wet and dry combability, enhances foam feel, and increases perceived conditioning without heavy buildup.
It also improves skin feel by reducing tightness and dryness after cleansing.

CONDICARE PQ-7 improves manageability, shine, and overall hair appearance.
It is suitable for daily-use and sulfate-free formulations.

From a safety perspective, CONDICARE PQ-7 is considered low in toxicity and suitable for rinse-off and leave-on cosmetic products within regulatory limits.
Eye contact with concentrated material may cause mild irritation.
Prolonged skin contact with undiluted product may cause slight irritation in sensitive individuals.

CONDICARE PQ-7 is not flammable and does not present inhalation hazards under normal use conditions.
Large releases into water systems may increase organic load, although the polymer itself is not highly toxic to aquatic life.
Proper disposal according to local environmental regulations is recommended.

CONDICARE PQ-7 should be stored in tightly closed containers, protected from freezing and excessive heat.
