Ivory soap. The name itself conjures images of clean laundry, fresh scents, and a bar so pure it famously floats. But beneath the surface of this iconic brand lies a question that has lingered for generations: Is Ivory soap really soap? This article dives deep into the history, ingredients, and manufacturing process of Ivory to uncover the truth and separate fact from fiction.
A Historical Dive into Ivory’s Origins
To understand the debate surrounding Ivory’s “soapiness,” we need to journey back to its creation. In 1878, James Gamble, one of the co-founders of Procter & Gamble (P&G), sought to create a high-quality, affordable soap that would differentiate the company from its competitors. Legend has it that a worker accidentally left a mixing machine running for too long, incorporating more air into the mixture. This resulted in a lighter-density soap that floated – a happy accident that became Ivory’s defining characteristic.
The initial marketing campaign for Ivory was a stroke of genius. P&G declared that Ivory was “99 and 44/100% pure,” a claim that resonated with consumers seeking trustworthy products. This claim, while technically accurate, has been the subject of much debate and scrutiny over the years. But the power of this simple message propelled Ivory to become a household name. The floating property, emphasized in advertisements, further solidified its appeal. No more fishing for dropped soap!
What Exactly is Soap, Anyway? A Chemical Perspective
Before we can definitively answer whether Ivory is real soap, we need to understand what soap is on a chemical level. Soap is created through a process called saponification. This involves reacting fats or oils with an alkali, such as lye (sodium hydroxide or potassium hydroxide). The reaction breaks down the fats into fatty acid salts, which are the actual soap molecules, and glycerin, a humectant.
True soap, in its purest form, contains only these core components: fatty acid salts, glycerin, and water. However, most commercially available soaps, including Ivory, contain additional ingredients like fragrances, dyes, and preservatives. The presence of these additives is where the “real soap” debate often arises.
Distinguishing Soap from Detergent
It’s crucial to distinguish between soap and detergent. While both clean, they function differently. Detergents are synthetic cleaning agents derived from petroleum products. They generally contain surfactants, which lower the surface tension of water, allowing it to penetrate and lift away dirt and grime. Soaps, on the other hand, are derived from natural fats and oils. The key difference lies in their chemical composition and the raw materials used in their production.
Ivory Soap: Examining the Ingredients
So, what are Ivory soap’s ingredients? The ingredient list has evolved over the years, but generally includes:
- Sodium Tallowate: A soap made from tallow (animal fat).
- Sodium Cocoate or Sodium Palm Kernelate: Soaps made from coconut oil or palm kernel oil. These provide lathering properties.
- Water.
- Sodium Chloride: Table salt, used to help separate the soap from the glycerin during manufacturing.
- Sodium Carbonate: Washing soda, used as a pH adjuster.
- Sodium Silicate: Used as a corrosion inhibitor and to help maintain the soap’s texture.
- Fragrance.
Examining this ingredient list, we see both elements of “true soap” (sodium tallowate, sodium cocoate/palm kernelate, water) and additives (sodium chloride, sodium carbonate, sodium silicate, fragrance).
The “99 and 44/100% Pure” Claim: Fact or Fiction?
The famous “99 and 44/100% pure” claim is perhaps the most debated aspect of Ivory soap. While technically true, it’s also a clever marketing tactic. The percentage refers to the amount of fatty acid salts (the actual soap component) present in the bar, excluding impurities and additives.
However, some argue that the claim is misleading because it implies that the remaining percentage consists of “impurities” when, in reality, it includes ingredients like sodium chloride and sodium carbonate, which are intentionally added for functional purposes. It’s important to note that even “pure” castile soap contains unsaponified oils and glycerin, which would technically lower its “purity” percentage if calculated in the same way as Ivory.
Understanding the Manufacturing Process
To further understand the purity claim, let’s delve into Ivory’s manufacturing process. The process involves saponifying fats and oils with alkali. After saponification, the mixture is boiled and purified to remove excess alkali and impurities. Salt (sodium chloride) is added to separate the soap from the glycerin. The soap is then dried, shaped, and packaged.
The boiling and purification steps are crucial in achieving the high level of purity claimed by P&G. However, it’s also important to recognize that the added ingredients, while not “impurities” in the traditional sense, do contribute to the final composition of the soap.
Ivory Soap: Advantages and Disadvantages
Like any product, Ivory soap has its advantages and disadvantages:
Advantages:
- Affordable: Ivory is one of the most inexpensive soaps on the market.
- Mild: Its relatively simple formulation makes it generally gentle on the skin, especially compared to heavily fragranced or detergent-based cleansers.
- Hypoallergenic: Ivory is often recommended for people with sensitive skin or allergies due to its lack of harsh chemicals and dyes.
- Versatile: Beyond personal hygiene, Ivory can be used for a variety of cleaning tasks around the house.
- Nostalgia: For many, the scent and feel of Ivory soap evoke fond memories of childhood.
Disadvantages:
- Drying: While mild, Ivory can be drying for some skin types, particularly those with dry or sensitive skin. The removal of glycerin during manufacturing (to increase purity) can contribute to this effect.
- Limited Moisturizing Properties: Unlike soaps with added oils or emollients, Ivory doesn’t offer significant moisturizing benefits.
- Simple Formula: Some may find the lack of added ingredients like essential oils or natural extracts unappealing.
- The “Pure” Debate: The ongoing debate surrounding the “99 and 44/100% pure” claim can be off-putting to some consumers.
Alternatives to Ivory Soap
If you’re seeking alternatives to Ivory soap, consider the following:
- Castile Soap: Made from 100% olive oil (or other vegetable oils), castile soap is a truly natural and versatile option.
- Glycerin Soap: Glycerin soap contains a high percentage of glycerin, making it more moisturizing than traditional soaps.
- Handmade Soaps: Many small-scale soap makers create soaps with natural ingredients, essential oils, and beneficial additives.
- Syndet Bars: These are synthetic detergent bars that can be formulated to be very mild and moisturizing. Look for bars specifically designed for sensitive skin.
So, Is Ivory Soap “Real” Soap? The Verdict
Ultimately, whether or not you consider Ivory soap “real” soap depends on your definition. If you define soap as simply a product made through saponification, then yes, Ivory soap is real soap. It’s made from fats and oils reacted with alkali.
However, if you define soap as a product containing only the core components of saponification (fatty acid salts, glycerin, and water), then Ivory falls short due to the presence of added ingredients. It’s more accurate to describe Ivory soap as a commercial soap that contains both soap molecules and additives.
The “99 and 44/100% pure” claim, while not entirely misleading, should be interpreted with a grain of salt. It’s a testament to Ivory’s effective purification process, but it doesn’t mean that the remaining percentage is insignificant or undesirable.
The Enduring Legacy of Ivory Soap
Despite the debates surrounding its composition and marketing, Ivory soap remains a beloved and recognizable brand. Its affordability, mildness, and versatility have cemented its place in American households for over a century. While it may not be the purest or most luxurious soap on the market, Ivory offers a reliable and effective cleaning experience that continues to resonate with consumers. Its long history and iconic status are a testament to its enduring appeal.
The conversation surrounding Ivory soap highlights the complexities of product labeling and consumer perception. It encourages us to look beyond marketing slogans and delve into the ingredients and manufacturing processes of the products we use every day. Ultimately, the choice of whether or not to use Ivory soap is a personal one, based on individual preferences and skin sensitivities. Hopefully, this article has provided you with the information necessary to make an informed decision.

Is Ivory Soap truly “real” soap, or is it something else?
Ivory Soap is indeed real soap, produced through a traditional saponification process where fats or oils are combined with an alkali, such as lye (sodium hydroxide). This chemical reaction creates soap and glycerin as byproducts. The key difference with Ivory Soap lies in its higher purity and lower percentage of free alkali compared to some other soaps, contributing to its gentler nature.
The product’s formulation focuses on minimizing impurities and excess alkali that can sometimes irritate the skin. While some modern “soaps” are actually synthetic detergents (syndets), Ivory Soap remains a traditionally made soap, adhering to the fundamental chemical definition of soap derived from fats and oils.
What makes Ivory Soap float, and is this a characteristic of all real soaps?
Ivory Soap floats because of air incorporated during the manufacturing process. The soap mixture is whipped vigorously before being allowed to solidify, creating tiny air bubbles throughout the bar. These air bubbles reduce the overall density of the soap, making it less dense than water, hence its ability to float.
Floating is not a universal characteristic of all real soaps. The density of soap depends on the ingredients used and the manufacturing methods employed. Many soaps, especially those with higher oil content or heavier additives, are denser than water and will sink. The floating aspect of Ivory Soap is a specific feature achieved through a deliberate air-incorporation technique.
Does Ivory Soap contain any harsh chemicals or additives that might irritate sensitive skin?
Ivory Soap is formulated to be a mild and gentle soap, typically containing fewer additives and fragrances than many other commercially available soaps. Its composition often consists primarily of sodium tallowate, sodium cocoate or sodium palm kernelate, water, sodium chloride, sodium silicate, and tetrasodium EDTA. These ingredients contribute to cleansing and hardness.
However, even with its relatively simple formula, some individuals with extremely sensitive skin might experience mild irritation. Sodium lauryl sulfate (SLS), while not typically a primary ingredient, may be present in some formulations, and this can be a potential irritant for sensitive individuals. It’s always recommended to perform a patch test on a small area of skin before widespread use, especially if you have known sensitivities.
How does Ivory Soap compare to modern “beauty bars” or body washes in terms of ingredients and cleansing action?
Ivory Soap is a traditional soap relying on saponification for its cleansing action, effectively removing dirt and oils by emulsifying them with water. This contrasts with many modern “beauty bars” and body washes, which are often synthetic detergents (syndets) formulated with surfactants, moisturizers, and other additives. Syndets can sometimes be milder and less drying than traditional soaps.
Modern beauty bars and body washes often contain ingredients like synthetic fragrances, dyes, and preservatives to enhance their aesthetic appeal and shelf life. While Ivory Soap’s cleansing power is generally effective, it may lack the added moisturizing benefits of some modern formulations. The choice between them depends on individual skin needs and preferences.
Is Ivory Soap environmentally friendly, considering its ingredients and production methods?
Ivory Soap’s environmental friendliness depends largely on the sourcing of its ingredients, primarily the fats and oils used in the saponification process. If these fats and oils are sourced sustainably, it contributes positively to the soap’s environmental profile. However, if derived from unsustainable sources, like palm oil from deforested areas, it raises environmental concerns.
The production process itself also plays a role. Traditional soap-making processes can be relatively energy-intensive, and the disposal of byproducts needs careful management. Modern Ivory Soap formulations sometimes incorporate environmentally friendly packaging and sustainable sourcing practices, but it’s important to check the product labeling for specific certifications and claims.
Can Ivory Soap be used for purposes other than bathing and washing hands?
Yes, Ivory Soap has a history of being used for a variety of purposes beyond personal hygiene. Due to its mildness and purity, it has been used for cleaning delicate fabrics, creating homemade play dough, and even as a lubricant for drawers or zippers that are stuck. Its simple composition makes it relatively safe for a range of applications.
The soap’s soft texture when wet makes it easy to mold and shape, contributing to its versatility. However, it’s essential to remember that it is still a soap and should not be ingested or used in ways that could cause harm. Always test a small, inconspicuous area before using Ivory Soap for any unconventional cleaning or crafting purpose.
Has the formula of Ivory Soap changed significantly over the years, and if so, how has this affected its quality?
While the core principle of Ivory Soap’s formulation – its purity and floating characteristic – has remained consistent, there have been some adjustments to the ingredients and manufacturing processes over the years. These changes have often been driven by cost considerations, ingredient availability, or consumer preferences.
Modern formulations may include synthetic ingredients or alter the ratios of different oils used in the saponification process. While the goal is generally to maintain the soap’s mildness and cleansing efficacy, some consumers may perceive subtle differences in texture, lather, or scent compared to older versions. It’s important to note that these changes aren’t necessarily indicative of a decline in quality, but rather an adaptation to evolving market conditions and technological advancements.
