Cosmetic Science and Technology: Theoretical Principles and Applications covers the fundamental aspects of cosmetic science that are necessary to understand material development, formulation, and the dermatological effects that result from the use of these products. The book fulfills this role by offering a comprehensive view of cosmetic science and technology, including environmental and dermatological concerns. As the cosmetics field quickly applies cutting-edge research to high value commercial products that have a large impact in our lives and on the world's economy, this book is an indispensable source of information that is ideal for experienced researchers and scientists, as well as non-scientists who want to learn more about this topic on an introductory level. Chemical engineers, chemists, physical chemists and cosmetic chemists in cosmetics research and development, dermatologists, toxicologists.

We use cosmetics to cleanse, perfume, protect and change the appearance of our bodies or to alter its odors.

Whatever the process one wishes to take, there is one goal in mind: covering up imperfections Figure 2. Most cosmetic products are complex mixtures of chemical compounds that are directly applied to the skin. Unlike pharmaceutical products, cosmetics are not intended to cure diseases.

However, modern cosmetics are often -functional. Thus, some cosmetic products contain quasi-drugs, although their effects on the body remain mild and gentle.

Because cosmetics are freely used by consumers with no daily-exposure limits, the absorption of quasi-drugs and other ingredients through the skin needs to be carefully controlled, which makes monitoring transdermal drug absorption one of the important subjects in cosmetic science. When seeking out personal care, consumers want the new and exciting, while their expectations for and of functional and efficacious ingredients and products grow. In addition, as a result of global economics, consumer frugality has become the new normal, and this, too, plays a role in what consumers expect from the performance of their products.

Consumers will continue to spend on beauty products, but as their spending power decreases, they're ever quicker to move on from a product they deem as not living up to its promises.

Consumers set the parameters and will continue to seek out the most effective beauty products for their needsand value is determined first on efficacy. On the face of it, reaching today's consumers and winning their buy for the long term seems an ever more daunting proposition, but their quest and hunger for ever more efficacious and intriguing products actually translates to more opportunities to innovate for new unmet needs.

Turning innovation into success, though, will truly depend on an open and honest conversation with consumerslistening to their needs and being as clear as possible about claims and the potential for any given product. Brand owners must convey the value of new ingredients, formulas and products through clear language, with explanations of benefits based on scientific studies or other trials.

Backing good ingredients and products by developing smart marketing campaigns that are able to convey appropriate expectations from the use of products will foster a significant connection with consumersand that translates to the growth of business. General Use of CosmeticsCosmetic is a Greek word which means to 'adorn' addition of something decorative to a person or a thing.

The luminance contrast between facial features and facial skin is greater in women than in men, and women's use of make-up enhances this contrast.

In black-and-white photographs, increased luminance contrast enhances femininity and attractiveness in women's faces, but reduces masculinity and attractiveness in men's faces. In Caucasians, much of the contrast between the lips and facial skin is in redness. Red lips have been considered attractive in women in geographically and temporally diverse cultures, possibly because they mimic vasodilation associated with eternal desire Primers are so beloved by experts because they can do so much more than just make foundation go on smoother.

This product has a creamy texture and applies smoothly. Many makeup primers are formulated with silicone-based polymers, like dimethicone, because of their ultra-smoothing effects. Photoaged skin results from various environmental factors, most importantly chronic sun exposure.

The facial primer was shown to be effective and well tolerated for immediate and longterm improvement in the appearance of mild-tomoderate hyperpigmentation and fine lines associated with photodamage when used over a week period [82][83][84][85].

Это ты, приятель? - Он почувствовал, как рука незнакомца проскользнула к его бумажнику, чуть ослабив хватку.  - Эдди! - крикнул.  - Хватит валять дурака. Какой-то тип разыскивал Меган. Человек не выпускал его из рук.

С каких это пор заместитель директора начал действовать в обход фильтров. Сотрудникам лаборатории платили хорошие деньги, чтобы они охраняли компьютерные системы АНБ, и Чатрукьян давно понял, что от него требуются две вещи: высочайший профессионализм и подозрительность, граничащая с паранойей. Черт возьми! - снова мысленно выругался.  - Никакая это не паранойя. Этот чертов компьютер бьется над чем-то уже восемнадцать часов.

Он заправил рубашку в брюки и оглянулся. Позади уже закрывались двери. Беккер понял, что, если его преследователь находится внутри, он в западне.

Такая архитектура стала популярной в те времена, когда церкви одновременно служили и крепостями, защищавшими от вторжения мавров, поскольку одну дверь легче забаррикадировать. Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме.

Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении. - Коммандер, - все же возразила она, - это слишком крупная неприятность, и с ней не стоит оставаться наедине. Вам следовало бы привлечь кого-то. - Сьюзан, появление Цифровой крепости влечет за собой очень серьезные последствия для всего будущего нашего агентства.

Сьюзан встретилась с ним взглядом и прикусила губу. - Ничего, - выдавила. Но это было не. Терминал Хейла ярко светился. Она забыла его отключить.

 Он называл ее… - Речь его стала невнятной и едва слышной. Медсестра была уже совсем близко и что-то кричала Беккеру по-испански, но он ничего не слышал. Его глаза не отрывались от губ Клушара.

 Да, но я на всякий случай заглянул в Интернет, запустив поиск по этим словам. Я не надеялся что-либо найти, но наткнулся на учетную запись абонента.  - Он выдержал паузу.

 Да. Шестнадцать. - Уберите пробелы, - твердо сказал Дэвид. - Дэвид? - сказала Сьюзан.
