Why are some innovative aerosol products not marketable?
Every aerosol product wants to be commercially successful, but there are always some products that fail to do so-or that some products seem to be successful, but for one reason or another, this success is ultimately short-lived. These failures, regardless of size, have many characteristics. For example, losses due to unexpected corrosion, changes in color and smell, patent infringement, and regulatory restrictions. Or just because consumers are not interested in them.
Today, keeping up with all the elements that must be tested or considered is a difficult challenge for product formulators. There are more than 500,000 kinds of raw materials, and hundreds of cans and valves to choose from. Any major mistakes in the choice may turn the development plan back for months or even stalemate. In addition to the technical field, other negative events may also occur. For example, if the marketing director supporting the new project retires or resigns, his successor may have other priorities, leading to the deprivation of the project.
Fortunately, in most cases, defective aerosol products are detected during the development phase. The occurrence of such products entering the market is very rare, and most marketers have a "product recall" instruction manual to deal with this situation. However, almost all defective prototype products have only been on the shelf for decades and have never been used.
Summarizing some industry experiences that are "disconnected" in product development may help prevent such incidents in the future.
The earliest tank corrosion event may have occurred in 1953, when the manager of a product distribution warehouse informed a salesperson that his newly-made pyrethrin-DDT insecticide stained some cartons and found that the product leaked to the concrete floor on. The cause of the leak was quickly found: the product R & D team used chemically pure (dry) grade dichlorodiphenyltrichloroethane (DDT) in its formulation, but the purchasing department ordered a lower cost Commercial grade products usually contain about 0.3% moisture. The free water slowly hydrolyzed the CFC-11 (trichlorofluoromethane) propellant components, forming a small amount of hydrochloric acid, enough to penetrate the tinplate tank. Later, two companies supplying tinplate cans started the development of organic lined cans. The supplier found that 0.5% nitromethane would prevent CFC-11 from being hydrolyzed by water. It was called CFC-11-S at the time.
Around 1951, Carter-Wallace developed a patented shaving cream foam, using about 9% of chlorofluorocarbon (CFC) propellant. Its main competitors believe that this patent is invalid, and began to produce similar aerosol products. They then filed a lawsuit in 1953, and the court finally decided to support the patent. Carter-Wallace received an award of approximately $ 3 million, but soon its competitors developed an excellent shaving cream foam with a 4% low-cost, low-odor hydrocarbon propellant. This formula is clearly beyond the scope of patents. This marks the first use of the popular hydrocarbon propellant.
Phenolphthalein and thymolphthalein are commonly used color indicators for measuring pH in chemical titration. When the pH value is above 7.8, phenolphthalein changes from colorless to light red in the water-based solution. Similarly, when the pH value is higher than 8.1, thymolphthalein turns bright blue. The experimental results found that when the hair and scalp were massaged, the aerosol shampoo foam containing the indicator color would become colorless. This is because the outer layer of the stratum corneum of the skin contains lactic acid, uric acid, free fatty acids, etc. A pH gradient ranged from 4.3 to 5.8, with an average value of about 5.4 at 25 ° C (77 ° F). When the colored shampoo foam dissolves, these acidic substances in the foam become white. The R & D team believes that this "miracle" transformation may have important commercial significance. The sales staff agreed and considered the names "PinkyPoo" and "BluPoo". Fortunately, at the beginning of the marketing plan, the legal department reviewed the file and pointed out that these two colorants did not enter the US Food and Drug Administration (FDA) approved cosmetic ingredient list because they have never been used before. It took years of testing to obtain approval, so the project was abandoned.
Over the years, some aerosol products have entered the market, but they have to be withdrawn due to unexpected problems. Around 1975, chemist Sam Prussen, a consultant for Dart Industries, developed a self-heating aerosol shaving cream and other related products. When 6% hydrogen peroxide (H2O2) solution is mixed with sodium thiosulfate (Na2SO3), heat is generated. Prussen worked with a large valve company to design a valve whose dip tube at the tail descends to the bottom of a 0.94-OD plastic inner container containing hydrogen peroxide (H2O2), while the lateral dip tube enters the aerosol Shaving cream at the bottom of the jar. The function of the valve is to make the separated components proportional to the internal and external products at the same time.
