Guide Review - Fels Naptha Laundry Soap - Laundry Product Review

Fels-Naptha is a product that has graced laundry rooms for more than 100 years. With an interesting history in the Fels family, the laundry soap bar is now produced by Dial (Henkel). You can usually find it with laundry products. It is not recommended for use on skin.

The original formula contained napthalene, a benzene petroleum-based solvent. Today's formula contains no napthalene. The label listed the ingredients as: cleaners, soil & stain removers, chelating agents, colorants, perfume. A more comprehensive list is available on the Fels-Naptha website:

  • Soap (sodium tallowate* and sodium cocoate* (or) sodium palmate kernelate* and sodium palmate*)
  • Water
  • Talc
  • Coconut acid*, palm acid* or tallow acid*
  • PEG-6 methyl ether
  • Glycerin
  • Sorbitol
  • Sodium chloride
  • Pentasodium pentetate and/or tetrasodium etidronate
  • Titatium dioxide
  • Fragrance
  • Acid Orange (CI 20170)
  • Acid yellow 73 (ci43350)
  • *contains one or more of these ingredients

    Fels-Naptha is most effective on oil-based stains like make-up, chocolate and body soil. You use by wetting the stained area, rubbing it with the bar of soap, allow the stain to sit for one minute or more and then wash as usual.

    It is also effective for removing poison ivy resins from clothing that has been exposed. And, you can use Fels-Naptha as an ingredient in homemade laundry detergent by shaving or grating the bar.

    I have used Fels-Naptha to remove oily stains and it still works today. It is not effective on every type of stain but can find a spot in your laundry room.
