The aims of this study were to measure the physicochemical properties of miconazole nitrate (MCZ : a brand-name (MCZ-A) and three generic (MCZ-B, -C, and -D)) creams, to conduct human sensory testing of those creams. The flattening, viscoelasticity, and water content of each cream were measured and each cream was subjected to near-infrared (NIR) absorption spectroscopy and sensory testing. The yield value was calculated based on measured flattening and was 734.8 dynes/cm2 for MCZ-A, 1198.9 dynes/cm2 for MCZ-B, 461.3 dynes/cm2 for MCZ-C, and 3112.3 dynes/cm2 for MCZ-D. Measurement of viscoelasticity and viscosity revealed that MCZ-C had a smaller tanδ than the other 3 creams at 25ºC. NIR absorption spectroscopy revealed that MCZ-A had the highest absorption peak due to hydroxyl groups, followed by MCZ-C, -B, and then -D. Measurement of water content revealed that MCZ-A had a water content of 65.9%, MCZ-B, -C, and -D had a water content of around 56.3%. Human sensory testing revealed differences between MCZ-A and MCZ-C and between MCZ-B and MCZ-D in terms of spreadability and feel. These findings indicate that differences in water and oil content and emulsification resulted in the creams having different physical properties, such as flattening, internal structure, and dynamic viscoelasticity. NIR absorption spectroscopy, which allows non-destructive measurement of a sample’s physicochemical properties, and measurement of viscoelasticity and viscosity, which allows measurement of a sample’s dynamic viscoelasticity, revealed differences in the physical properties of creams.

...c viscosity in particular is an important component of the association between physicochemical properties and feel.
In addition, creams consist mainly of additives, so a preparation can be greatly affected by additives. In studies of ACV and TA, this Laboratory compared preparations with different additives. However, no studies have compared the characteristics of preparations with the same types of additives, and no studies have examined physical properties and feel.
The current study assessed the physicochemical properties of MCZ creams with the same additives. Creams were also compared in human sensory tests. As reported here, findings provided information that allows selection of a preparation in accordance with a patient’s preferences and the intent of the prescribing physician without requiring use of the preparation in a clinical setting beforehand.
In World War II the soldiers used a jelly-like substance, called “red vet pet” to prevent themselves from the sun. Finally, Benjamin Green combined this substance with cocoa butter and coconut oil, which created the new line of Coppertone suntan cream. Coppertone has come a long way, to make their product better. As they changed the product, the advertisement changed over the years to appeal to the audience. Although both of these advertisements are being presented to get people to buy Coppertone, the modern day advertising is more appealing than 1944 advertisement; the modern day advertisement has a better focal point, action, general feeling and mood, selection of elements, and audience.
SUMMARIZE: The article grants information on new models in cosmetics to take the place of animal experimentation. It goes on to talk about how the European Union has now banned using animal-based test for cosmetic reasoning. Pharmaceutical companies and regulatory agencies have been using computer-like tools to assess the toxicity it has for years. The author incorporates information on cosmetics and the outlook on further research. ‘According to experts, combination of laboratory-based with virtual work will be the future of testing and is progressing faster than they expected.” (87 words)
Day by day, I was losing the radiant and shine of my skin. I was a little distressed. The day I saw age spots, wrinkles on my face, I was very upset. I adopt a number of methods to combat the visible signs of aging. But none of them could work. After watching plenty of advertisements of XYZ Smart Collagen, I tried using this cream. You won’t believe, it was just a miracle for me. With the regular use of the cream as per the directions, I was able to achieve beautiful, smoother and younger-looking skin once again.

The Beauty Industry being such a wide market of services and products include providing for the care of our skin, hair, selling of perfumes and cosmetics (“What is the Beauty Industry?”2014) and now developing more extensively into basic cosmetic surgery and treatments, now gives society a big opportunity to pamper and nourish themselves in more extensive ways. Throughout this essay, the branches of dermatology and dermal therapies will be explained; common skin disorders and specifically a treatment called ‘Ultrasonic Peeling’ and how it can potentially help with skin disorders imposed today will be explored and described in detail. After the investigation of what Ultrasonic Peeling is and how it works, I will also state my opinion on how well I think the treatment benefits its users, give my evaluation if I would consider using it, what I think the positives and negatives are and in scenario, assess whether it is a treatment that more salons should consider offering.
The same procedure was done using 10ml of CV and 20ml of sodium hydroxide, both separately diluted to 50ml and added in a large beaker. The absorbance was recorded. In the last trial, 10ml of CV, 10ml of NaOH were diluted to 50ml. Before adding the two mixtures, 1ml of soap was added to the NaOH solution and then poured into a large beaker, along with the CV. Absorbance was recorded and the materials

As we age, our skin not only gets less elastic, but it also loses the ability to create certain biologically compositions that help keep the skin soft, smooth, and healthy-looking. The best anti wrinkle creams will usually contain compounds or ingredients that try to mimic the effects of these compositions, since they tend to work -albeit not permanently- and the skin usually absorbs them fairly
The flow time (t) is equal to kŋƿ, where k is the viscometer constant, ŋ is the viscosity, and ƿ is the density of the solution. Through experiment, the determination of viscosity can be done by measuring the flow time in a viscometer. It should be taken in consideration that changes in viscosity are always relative to that of the native protein and that of the solvent matrix or blank. The ratio of the viscosity (ŋ) of the sample to the viscosity of the blank (ŋ˳) is equal to the relative viscosity (ŋ/ ŋ˳). The relative viscosity is given by the following equation with the use of the same viscometer for both solution and solvent. [2] The equation is as
This stuff really is the best natural anti aging skin care product you could possible use.
In order to improve the quality of all its products, Lancôme setup several research centers which collaborate with the international medical community to deepen its understanding of skin. Also, there are more than 2000 experts working there who are professional in innovating and developing products in respond to either problematic skin or normal skin.
Teens who suffer from acne are always on the lookout for the best acne skin cream and aging women and men search for effective anti-wrinkle creams. Unfortunately, not all creams and lotions work for everyone. Some formulations may contain harmful synthetic ingredients which will not reduce wrinkles and acne and which may also harm the skin. Among the myriad skin care products available in the market, the only way you can find the right ones is by going through beauty product reviews on authentic review sites.
However, we must keep in mind that oil and water do not bind together naturally. The atoms in water have a slight positive and negative charge, therefore they bind with other charged atoms. Since oil is uncharged, water cannot bind to it. Therefore, a chemical binds both oil and water, this element is called a surfactant. A surfactant must have two parts, one that binds water and another that binds oil. Water, an oil-based component, and a surfactant must undergo a process that thoroughly mixes them together. To be sure that the final product is water-based, we must add more water than the oil component, so that mixing them will produce an aqueous phase with little amounts of oil dispersed throughout. Choosing which surfactant to use, affects the ratio of water to oil that can be mixed. For moisturizers, the surfactants typically used are amphoteric surfactants and nonionic surfactants; fatty acid alcohols such as cetearyl alcohol or stearyl alcohol, are the simplest non-ionic
Skin care products may give common side effects and sometimes consumers are not aware of the negative consequences of using the product, and continue to use it without realizing it. When using skin care products for the first time, users may experience early symptoms. Some of the users that experience common side effects will start to think that they might have severe problems or disease, even though that side effect is normal. There are many cases with frequent use of the product, there will be no longer side effects occurs but however, some side effects may be worsen. This second objective, will be able to make it easier for users to find and identify common side effects that occur to them when using skin care
