AbouttheSeries
The CosmeticScienceand Technology series was conceived to permit discussion ofabroad
rangeof current knowledge and theories of cosmeticscience and technology.Theseries is
composed of both books written by asingleauthor and edited volumes with anumber of
contributors.Authorities fromindustry,academia, and thegovernment participatein writing
thesebooks.
The aimof theseries is to cover the many facets of cosmeticscience and technology.Topics are
drawn from a wide spectrumof disciplines ranging from chemistry,physics,biochemistry, and
analytical and consumer evaluations to safety, efficacy,toxicity,and regulatory questions.
Organic,inorganic,physical and polymer chemistry,emulsion and lipidtechnology,
microbiology,dermatology,and toxicology all play important roles in cosmeticscience.
Thereis littlecommonality in thescientific methods, processes, and formulations required for
thewidevariety of cosmetics and toiletries in the market.Products range frompreparations for
hair,oral, and skin careto lipsticks,nail polishes and extenders,deodorants,bodypowders and
aerosols,to quasi-pharmaceutical over-the-counter products such as antiperspirants,dandruff
shampoos,antimicrobial soaps,and acne and sun screen products.
Cosmetics and toiletries represent ahighlydiversified field involving many subsections of

scienceand “art.”Even in these days of high technology,art and intuitioncontinueto play an
important part in thedevelopment of formulations,their evaluation,selection of raw materials,
and,perhaps most importantly,thesuccessful marketing of new products.The application of
more sophisticated scientific methodologies that gained steam in the1980s has increased in such
areas as claimsubstantiation,safety testing,product testing,and chemical analysisand has led to
abetter understanding of theproperties ofskin and hair.Molecular modeling techniques are
beginning to beapplied to data obtained in skin sensory studies.
Emphasis in theCosmetic Science and Technology series is placed on reporting thecurrent
status of cosmetictechnology and scienceand changing regulatory climates and presenting
historical reviews. Theseries has now grown to 26 books dealing with theconstantly changing
technologies and trends in thecosmeticindustry,including globalization.Several of thevolumes
havebeen translated into Japanese and Chinese.Contributionsrangefrom highly sophisticated
and scientifictreatises to primers and presentations of practical applications.Authors are
encouraged to present their own concepts as well as established theories.Contributors havebeen
asked not to shy away fromfields that are in astate of transition,nor to hesitateto present
detailed discussionsof their own work. Altogether,weintend to develop in this series a
collection of critical surveys and ideas covering diversephases of thecosmeticindustry.
The13 chapters in Multifunctional Cosmetics cover multifunctional products forhair,nail, oral,
and skin care, as well as products with enhanced sunscreen and antimicrobial properties Several
chapters deal with thedevelopment of claimsupport data,the roleof packaging,and consumer
research on theperception of multifunctional cosmeticproducts.The authors keep in mind that
in thecase of cosmetics,it is not only thephysical effects that can be measured on theskin or
hair,but also thesensory effects that have to betaken into account.Cosmetics can have a
psychological and social impact that cannot beunderestimated.
I want to thank all thecontributors for participating in this project and particularly theeditors,
Perry Romanowski and Randy Schueller, for conceiving,organizing,and coordinating this book.
It is thesecond bookthat they havecontributed to this series and we appreciate their efforts.
Special thanks aredueto SandraBeberman and Erin Nihill oftheeditorial and production staff
at Marcel Dekker,Inc.Finally, I would liketo thank my wife, Eva, without whoseconstant
support and editorial help I would not haveundertaken this project.

Although synthetic polymers first appeared in the last century, it has been the twentieth
century,especiallythesecondhalf,whichhaswitnessedanexplosivegrowthinthedevel-

Polymerscience—alreadystartingfromasolidfoundationwiththeearlyrecognition
that many natural products, including proteins and polysaccharides, are polymeric—has
grown apace with these developments. Today some would aver that it has been difficult
