SyntranŽ 5903
Opacifier For Personal Care

SYNTRAN 5903 is a Styrene/Acrylates Copolymer

SYNTRAN 5903 is a styrene/acrylic emulsion which is designed to modify the visual appearance of personal care products such as liquid shampoos, bath and shower products, and liquid hand soaps, from clear to opaque without affecting the other desired properties. SYNTRAN opacifiers improve brightness and whiteness, can be used at significantly lower levels, and have excellent formulation stability.


Performance Benefits

  • Highly effective opacifier (addition levels of 0.1 to 1.0 %)
  • Very broad compatibility with a wide variety of raw materials
  • Can be added pure or pre-diluted
  • Low odor

Typical Physical Properties

  • PHYSICAL FORM:     white dispersion
  • TOTAL SOLIDS:    35%
  • pH VALUE at 22°C:    7.0
  • VISCOSITY BROOKFIELD:    < 100 mPa.s
  • DENSITY AT 22°C:    1.03
  • HEAT STABILITY AT 52°c:     unchanged after 30 days
  • FREEZE THAW STABILITY:     protect from freezing

SYNTRAN 5903 should always be added at the end of the manufacturing cycle just after final adjustment. The product can be pre-diluted with soft or de-ionized water at a range of 1 part opacifier to 3-4 parts water prior use. The addition of opacifier to the base product needs to be made very slowly under good agitation.


SYNTRAN 5903 is not freeze-thaw stable and should therefore be kept at temperature of 5°C to 35°C.


SYNTRAN 5903 is very stable in original containers and storage tanks at ambient temperature for at least 6 months.  Open containers should be checked on a regular basis for, and protected against, bio-contamination, if necessary.

If SYNTRAN 5903 is stored in a diluted form, a preservative is required.


We know of no ill effects that could result from using SYNTRAN 5903 for the purpose for which it is intended or from processing it in accordance with current practice. According to the experience we have gained, and other information at our disposal, SYNTRAN 5903 does not exert any harmful effects on health, provided that it is used properly, due attention is given to the precautions necessary for handling chemicals, and the information and advice given in our Safety Data Sheet are observed.
