Ivory (French : Savon d'Ivoire) is an American flagship personal care brand created by the Procter & Gamble Company (P&G), including varieties of white and mildly scented bar soap that became famous for its claim of purity and for floating on water. Over the years, the brand has been extended to other varieties and products.
In 1840, the J.B. Williams Company in Glastonbury, Connecticut, manufactured soap under the name Ivorine. Williams decided to focus on its shaving soap and sold Ivorine to Procter & Gamble, which later developed Ivory. [1]
In 1879, James Norris Gamble, son of Procter & Gamble co-founder James Gamble and a trained chemist, developed an inexpensive white soap. [2] The name Ivory was created by Harley Procter, the other founder's son, who was inspired by the quote "[a]ll thy garments smell of myrrh and aloes and cassia out of the ivory palaces", from Psalm 45 of The Bible. [3] In September 1879, Procter & Gamble trademarked "Ivory" as the name of its new soap product. [4]
As Ivory is one of P&G's oldest products – it was first sold in 1879 – P&G is sometimes called "Ivory Towers", and its factory and research center in St. Bernard, Ohio, is named "Ivorydale". [5]
Ivory's first slogan, "It Floats!", was introduced in 1891. The product's other well-known slogan, "99+44⁄100% Pure", which was in use by 1895, was based on the results of an analysis by an independent laboratory that Harley Procter hired to demonstrate that Ivory was purer than the castile soap available at the time. [6]
Ivory bar soap is whipped with air in its production and floats in water. According to an apocryphal story, later discounted by the company, a worker accidentally left the mixing machine on too long, and the company chose to sell the "ruined" batch because the added air did not change the basic ingredients of the soap. When appreciative letters about the new, floating soap inundated the company, P&G ordered the extended mix time as a standard procedure. However, company records indicate that the design of Ivory did not come about by accident. In 2004, over 100 years later, the P&G company archivist Ed Rider found documentation that revealed that James N. Gamble, who was a chemist, had discovered how to make the soap float and noted the result in his writings. [7]
In October 1992, Procter & Gamble market-tested a new Ivory formula, a "skin care bar" that would address customer complaints about dryness but would not float like the original. [8] In October 2001, P&G tested the sinking bar soap as part of an advertising campaign in the United States, in a six-month plan to release 1,051 soap bars that sink, among other bars that float, to see if people would notice the sinking bars, even if given a cash reward of up to $250,000. [9] The D. L. Blair company, part of Draft Worldwide, a unit of the Interpublic Group of Companies, was assigned to administer the contest. [9]
Ivory is currently a small brand by P&G standards. The Ivory brand includes the classic bar soap, clear liquid soap (discontinued before 2016), hair and body wash, dish liquid, and a mild laundry detergent (not a soap) product called Ivory Snow. Research in 2001 by Lehman Brothers revealed that the U.S. sales of all Ivory products, including the liquid soap and dish detergent, represented less than 1% of P&G's total worldwide sales in the 52 weeks ended September 9, 2001. [9]
A classic Ivory soap bar contains sodium tallowate, sodium cocoate or sodium palm kernelate, water, sodium chloride, sodium silicate, magnesium sulfate, and fragrance. The soap has a determined pH value of 9.5. [10]
Ivory dishwashing liquid contains water, sodium lauryl sulfate, sodium laureth sulfate, alkyl dimethyl amine oxide, sodium chloride, PPG-26, cyclohexanediamine, phenoxyethanol, methylisothiazolinone, and fragrance. [11] It is sometimes considered a detergent instead of a soap.
New varieties of Ivory soap contain new ingredients. Simply Ivory (French: simplement ivory) contains sodium tallowate and/or sodium palmate, water, sodium cocoate or sodium palm kernelate, glycerin, sodium chloride, fragrance, and one or more of the following: coconut acid, palm kernel acid, tallow acid, palmitic acid, and tetrasodium EDTA. Adding glycerol and fatty acids typically reduces the soap's harshness, while tetrasodium EDTA is used primarily to reduce soap scum formation. Ivory soap packaging has omitted the words "soap" or "float", and is now produced with improved formulas.
A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. There are a large variety of detergents, a common family being the alkylbenzene sulfonates, which are soap-like compounds that are more soluble in hard water, because the polar sulfonate is less likely than the polar carboxylate to bind to calcium and other ions found in hard water.
Surfactants are chemical compounds that decrease the surface tension or interfacial tension between two liquids, a liquid and a gas, or a liquid and a solid. Surfactants may function as emulsifiers, wetting agents, detergents, foaming agents, or dispersants. The word "surfactant" is a blend of surface-active agent, coined c. 1950.
Sodium cocoate is a mixture of fatty acid salts of coconut oil that is used in some soaps.
Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes and fittings. Water softening is usually achieved using lime softening or ion-exchange resins but is increasingly being accomplished using nanofiltration or reverse osmosis membranes.
Joy is an American brand of dishwashing liquid detergent owned by JoySuds, LLC. The brand was introduced in the United States in 1949 by Procter & Gamble. In 2019, Procter & Gamble sold the rights to the Joy brand for the Americas to JoySuds, LLC.
Zest is an American brand of soap and body wash owned by High Ridge Brands for the United States, Canada and Puerto Rico and by Unilever for the rest of the world. It was originally introduced by Procter & Gamble in 1955 with the slogan "For the first time in your life, feel really clean."
Fairy is an international brand, primarily used for washing up liquid and dishwasher detergent, owned by the American multinational consumer products company, Procter & Gamble. The brand originated in the United Kingdom in 1898 and is now used on a number of P&G products in various markets.
Ajax is a brand of household cleaning products and detergents made by Colgate-Palmolive. The brand is also licensed by Colgate-Palmolive in the United States, Canada and Puerto Rico.
Laundry detergent is a type of detergent used for cleaning dirty laundry (clothes). Laundry detergent is manufactured in powder and liquid form.
Dishwashing liquid, also known as dishwashing soap, dish detergent, and dish soap is a detergent used to assist in dishwashing. It is usually a highly-foaming mixture of surfactants with low skin irritation, and is primarily used for hand washing of glasses, plates, cutlery, and cooking utensils in a sink or bowl. In addition to its primary use, dishwashing liquid also has various informal applications, such as for creating bubbles, clothes washing and cleaning oil-affected birds.
Shower gel is a specialized liquid product used for cleaning the body during showers. Not to be confused with liquid soaps, shower gels, in fact, do not contain saponified oil. Instead, it uses synthetic detergents derived from either petroleum or plant sources.
Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na4EDTA.4H2O. The properties of solutions produced from the anhydrous and hydrated forms are the same, provided they are at the same pH.
Shampoo is a hair care product, typically in the form of a viscous liquid, that is used for cleaning hair. Less commonly, shampoo is available in solid bar format. Shampoo is used by applying it to wet hair, massaging the product into the scalp, and then rinsing it out. Some users may follow a shampooing with the use of hair conditioner.
A soap substitute is a natural or synthetic cleaning product used in place of soap or other detergents, typically to reduce environmental impact or health harms or provide other benefits.
Woolite is an American brand of laundry detergent and cleaning products owned by the British multinational company Reckitt.
