Chem/IUPAC Name:

2-Hydroxyethyl cellulose ether,

 reaction products with N,N,N-trimethyl-N-oxiranylmethylammonium chloride and N-dodecyl-N,N-dimethyl-N-oxiranylmethylammonium chloride

EINECS/ELINCS No:921-309-5
COSING REF No:58846

It is a hydrophobically-modified cationic conditioning polymer for softness, smoothness and manageability in wet and dry hair.

Polyquaternium-67. SoftCAT™ Polymer SL-5 by Dow is a hydrophobically-modified, premium performance cationic conditioning polymer, sensory enhancer. 

It gives hair a softer, smoother feel than ever before, without unwanted build-up or volume-down effects. 

It is recommended for normal and chemically treated & damaged hair. 

It offers soft hair that looks visibly healthier and manageability without build-up. 

It delivers active ingredients in rinse-off formulations. SoftCAT™ Polymer SL-5 is used in clear formulations and greater silicone deposition efficiency. 

It is compatible with a wide range of surfactants. It can enhance volume and detangling. 

It is partially bio-renewable and provides dry & wet combing and frizz control.

What is POLYQUATERNIUM-67 used for?

  • Skin care: It can be used to enhance deposition of occlusive moisturizers (e.g., sunflower seed oil, petrolatum, etc.), sunscreen, fragrance, and other actives to the skin from cleansing formulations, such as body washes or facial cleansers. It is used as a dispersing agent in makeup products and sunscreens.
  • Hair care: It is mostly used as an antistatic to reduce static electricity by neutralizing the electrical charge on the surface of hair. As a film forming agent, it produces a continuous film on the hair, making them appear shiny and smooth. It conditions and leaves hair easy to comb, supple, soft and shiny and/or gives volume, lightness and shine. It is used in shampoo, conditioner, hair color and bleaching, hair treatment/serum, hair-loss treatment.

Origin

Polyquaternium-67 is a family of high viscosity quaternized hydroxyethyl cellulose (HEC) polymers with cationic substitution of trimethyl ammonium and dimethyldodecyl ammonium. It is based on a cellulosic backbone derived from natural and renewable wood and/or cotton sources.
