Toilet soap bars have undergone few major technical changes in the last century. Noteworthy improvements were floating soap,
the development of effective deodorant and antibacterial soaps, the so-called “hard water” bars, and advances in packaging
technology. The trends in these areas toward product and process improvement will accelerate in the 1970’s. New raw materials
are becoming available which will give greater formulation flexibility, with emphasis towards greater mildness and effectiveness.
Among these products are the synthetic fatty acids which could partially replace coconut acids, more effective broad spectrum
antibacterial agents for better control of skin microorganisms, and mild detergent additives with good physical properties
and less defatting tendency. In processing, the move is toward continuous soap-making equipment in place of the old kettle
processes which are still widely used. More powerful and specialized plodders are available; these will facilitate the development
of new product types.

The first soap germicide system to show activity against gram-negative organisms is described. Addition of a new germicidal
agent, 2-hydroxy-2′,4,4′-trichlorodiphenyl ether, combination of hexachlorophene and triclocarban which has been used in a
soap known to be effective against gram-positive organisms, has broadened its antibacterial spectrum without impairing its
mildness, safety and other desirable bar soap characteristics. Properties of the new system, including in vitro and in vivo
tests of its antibacterial activity, efficacy and safety, are discussed.

Summary A method has been developed for the determination of soda ash and sodium hydroxide in vegetable oil-alkali mixtures as a check
on proportioning equipment feeding oil and alkali. The method depends upon the potentiometric titration in one step of free
alkali and soap, using a pH meter and the glass electrode-calomel electrode assembly. The analysis is sufficiently rapid to
serve as a convenient control in a continuous refining process. 相似文献

Transition temperatures and enthalpies and some phase diagrams of pure odd and even sodium soaps have been determined by means
of dif-ferential thermal analysis and scanning calorim-etry. Branched sodium soaps have been added for comparison.
No essential difference has been found between the number, type, and enthalpy of the transitions of the neighboring odd and
even soaps. The total enthalpy and entropy of transition are consider-ably lower than those of the corresponding par-affins
and fatty acids. The entropy of the subneat-neat and perhaps of the neat isotropic transition has an alternating character,
which suggests a different methyl end-group packing for even and odd soap. These two facts suggest that the melted soap is
still in an organized state.

During the past decade, research by industry and government has developed numerous new chemical markets for fats and oils
derivatives. Lower prices for competitive raw materials have forced some of these new products into specialty markets. Economic
factors, such as the continual growth of the chemical industry, population increases, and high consumer demand, have allowed
for steady growth in the fat-derivative market. New fat-type plasticizers are currently consuming about 60 million pounds
of fats annually. Synthetic lubricants will probably be consuming 20 million pounds of fatty diesters annually by 1965. Animal
feeds consume approximately 600 million pounds of fats and fat derivatives annually and may eventually become the leading
domestic nonfood market for fats. The protective coating market as an outlet for fats continues to decline, and the continuing
shift to nonfat materials and changes in pain formulas indicate that, while the demand for protective coatings may increase,
the use of fats in their manufacture may not share in the increase. Nonfat chemical raw materials provide intense price competition
for fatty raw materials. Fat prices are influenced by the demand for use in food, soap, paints, and possibly animal feeds
rather than by the demand for use as chemical raw materials.

Transparent materials used for facial protection equipment provide protection against microbial infections caused by viruses and bacteria, including multidrug-resistant strains. However, transparent materials used for this type of application are made of materials that do not possess antimicrobial activity. They just avoid direct contact between the person and the biological agent. Therefore, healthy people can become infected through contact of the contaminated material surfaces and this equipment constitute an increasing source of infectious biological waste. Furthermore, infected people can transmit microbial infections easily because the protective equipment do not inactivate the microbial load generated while breathing, sneezing or coughing. In this regard, the goal of this work consisted of fabricating a transparent face shield with intrinsic antimicrobial activity that could provide extra-protection against infectious agents and reduce the generation of infectious waste. Thus, a single-use transparent antimicrobial face shield composed of polyethylene terephthalate and an antimicrobial coating of benzalkonium chloride has been developed for the next generation of facial protective equipment. The antimicrobial coating was analyzed by atomic force microscopy and field emission scanning electron microscopy with elemental analysis. This is the first facial transparent protective material capable of inactivating enveloped viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in less than one minute of contact, and the methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis. Bacterial infections contribute to severe pneumonia associated with the SARS-CoV-2 infection, and their resistance to antibiotics is increasing. Our extra protective broad-spectrum antimicrobial composite material could also be applied for the fabrication of other facial protective tools such as such as goggles, helmets, plastic masks and space separation screens used for counters or vehicles. This low-cost technology would be very useful to combat the current pandemic and protect health care workers from multidrug-resistant infections in developed and underdeveloped countries. 相似文献

Conclusion No laboratories are deeper in research than those of the soap and synthetic detergent manufacturers. W. L. Sims, president
of Colgate-Palmolive Company, was quoted recently in the New York press as follows: “probably 70% of the volume in our business
today comes from products that didn’t exist 10 years ago. The same thing will be true 10 years from now.”
This statement bears out the ever-changing dynamics of the industry. Much of the equipment and many of the materials covered
in this presentation did not exist a few years ago, and as research and engineering create new and improved products and new
and improved automated equipment, our means of handling these and other raw materials, even though they represent the best
available today, will be replaced by even more efficient methods and equipment. 相似文献

Summary A procedure for the complete semi-micro analysis of soap has been developed. Semi-micro methods are valuable in research work
and in legal cases where limited quantities of sample are available. In general, the analytical results obtained on a semi-micro
basis and on a macro basis are comparable. Very little special apparatus is required for the semi-micro analysis of a soap,
and most of the procedures employed present analogies with the usual methods of soap analysis.
