Origins of Fels Naptha Soap

The origins of Fels Naptha Soap can be traced back to its creation by Fels & Company in Philadelphia in 1893.

Fels Naptha Soap quickly became a reliable and versatile cleaner in households.

The Fels-Naptha Laundry Bar is a solid soap bar formulated with key ingredients to remove stains and dirt from fabrics effectively. Its unique composition includes the powerful cleaning agent, naphtha. Naphtha is a flammable liquid hydrocarbon that was originally used in the formula. However, in 1964, Fels & Company removed benzene, a cancer-causing agent, from the formula for safety reasons.

The Fels Naptha Soap is widely known for its ability to remove stubborn stains from fabrics. It is especially effective in treating greasy, oil-based, and ground dirt. This makes it an ideal choice for pre-treating laundry before washing. The soap bar can be applied directly onto the stain, allowing the powerful formula to penetrate and break down the stain before washing.

Key Ingredients in Fels Naptha Soap

Terpene hydrocarbons are the key ingredients found in Fels Naptha Soap, replacing its formula’s original use of naphtha. These terpene hydrocarbons are responsible for the soap’s powerful stain-removal capabilities, making it a popular choice for tackling tough laundry stains.

Here are three key ingredients found in Fels Naptha Soap:

  • Pine Oil: Derived from pine trees, pine oil is a natural solvent that helps break down and remove fabric stains. It is known for its strong cleaning properties and ability to cut through grease and grime.
  • Citronella Oil: Citronella oil is commonly used as an insect repellent and an effective stain remover in Fels Naptha Soap. It helps to dissolve and lift stains, leaving fabrics clean and fresh.
  • Limonene: Limonene is a compound found in citrus fruits and is often used as a natural cleaner due to its strong degreasing properties. Fels Naptha Soap aids in the removal of tough stains and helps eliminate odors.

These key ingredients work together to provide powerful stain removal and pre-treating capabilities, making Fels Naptha Soap a reliable choice for DIY laundry detergent and stain removal.
