|The Challenges for Personal Care Preservatives under the new European Regulations
Customer Application Specialist
Dow Microbial Control
Today's European regulatory environment presents many challenges for the use of preservatives in personal care and cosmetic products. These preservatives must undergo a stringent evaluation within the scope of the current EU Cosmetics Directive, which in turn is in the process of being substituted by the European Cosmetics Regulation, adding additional complexity for the cosmetics manufacturer in his choice of products for preservation.
In addition, the fact that Personal Care preservatives must also be supported for the use in cosmetics within the scope of the European Union's REACH Regulation, and indirectly the Biocidal Products Directive is also having an influence on the introduction of Personal Care preservatives on the market.
In this presentation, we will review the strategic challenges for Personal Care Preservatives in today's regulatory environment in Europe and examine its consequent implications for Turkey.
|Water Soluble Polymers for Foam Boost and Enhanced Sensory Appeal in Hand Dish Formulations
R&D Technical Service Scientist
Dow France SAS
This presentation shows an example of how innovation permeates from one application, namely personal care into another such as Hand Dish Care, thus bringing interesting benefits to the consumers and label claims for brand owners.
The presentation investigates the interactions of various cellulosic and other water soluble polymer chemistries in a Hand Dish formulation.
METHOCELTM and POLYOX TM water soluble polymers are multi-functional materials. METHOCELTM is a modified cellulose, derived in part from renewable resources, and therefore contributes to progressive sustainability improvements. Currently, these materials are not typically used in dish care applications.
Design of polymeric materials, e.g. modifying the hydrophobicity, molecular weight and charge substitution on a polymer backbone can produce a wide variety of different structures which have novel or unique properties to deliver enhanced skin sensorial, foam design and surface modification benefits, which are highly desirable in hand dishwashing liquids. Investigation into these effects and the structural/performance relationship offers many new benefits.
| Carboxymehyl inulin:
a vegetable based ingredient for liquid laundry detergents
Liquid laundry detergent is the up-and-coming segment in Middle East. Future move to compact product, low temperature wash and high efficiency washing machine has raised formulation challenges requiring innovative ingredients.
Recent works on carboxymethyl inulin (CMI) have demonstrated that its inclusion in liquid laundry detergents provides a significant boost in stain removal. CMI based formulations have been compared to commercial products from various market segments. Results indicate that varying the inclusion level of CMI allows matching the performance of these products from low tier up to premium brands. High inclusion level even results in performance above any tested detergents. These good performances are driven by the ability of CMI to bind hardness ions, defloculate stains and disperse soil and its good behaviour towards enzymes.
The vegetal origin of CMI, its exceptionally low toxicity and non persistent character ensure that it has a low impact on the environment. Therefore, CMI is an ingredient of choice to reduce oil dependency and meet consumer aspirations for sustainable detergents without compromising on cleaning performance.

|Bluestar Microemulsion Technology for Versatile Conditioner Formulations
Nalan Erkan Yavuzer
Sales Manager Personal Care
Amodimethicone is – per definition - a family of amine functionalized high molecular weight silicone polymers. They are well known for their high-performance conditioning potential in addition of many other benefits, including:
• targeted conditioning to areas of particularly damaged
• protection against thermal damage
• increase colour retention
• no build up
• impart gloss and shine
In contrast to pure Amodimethicone, Mirasil ADM-E is a microemulsion of amine functionalized polydimethyl-sioxane which is readily dispersable into aqueous formulations (e.g. for making transparent 2-in-1 shampoos). The internal oil phase volume contains of just about 40% Amodimethicone stabilized by Trideceth-6. Just ADM-E can be used as an emulsion base in order to incorporate additional amounts of lipophilic ingredients besides the Amodimethicone. Additional lipophilic ingredients could be: hair care/scalp actives, oil components…. and others. The mechanism of oil droplet stabilisation will be described. It will be shown that based on ADM-E a versatile family of different conditioners can be formulated.

|The Benefits of Silicones for Repairing Heat Damaged Hair Fibers
Suzanne Van Doorn
Life Sciences, Technical Service
Although conditioning is critical for healthy-looking hair, steps during hair styling such as frictional forces applied during brushing and actives contained in perming, straightening, bleaching and coloring products contribute to hair damage. Additionally, to perfect their hair styles, high-temperature heat-styling devices such as blow-dryers and straightening, curling and crimping irons are used. Daily repeated usages of these devices considerably damage hair fibers, resulting in hair frizz, dryness, breakage, split ends, lack of body or static unmanageability.1. Damaging effect of heat on hair fibers
High molecular weight Dimethicones are used since many years to smooth the cuticles and provide the perception of split end repair.
This study explores the benefits of silicones to repair heat damage hair.
New test protocols were used to heat damage bleached hair and specialty silicones were evaluated to demonstrate:
2. Repairing properties of derivative
polydimetylsiloxane based polymers:
• glide and smoothness restoration, decrease
of tangles and raspy feel of dry hair
• reduction of visual signs of damaged hair
• improvement of hair resistance to breakage,
reducing further risk of damage

|New innovations in the production of cosmetics: Hot/cold saves time and energy
Sales Project Manager
Ekato Systems GmbH
The hot/hot process is still used for manufacturing numerous cosmetic products. To manufacture products which are generally emulsion-based (creams, lotions, masks or on gels too etc.) water and oil-based phases are heated up to high temperatures. Substantial amounts of energy can be derived from these high temperatures, shown by very long cooling times.
Both product quantity and heat capacity are compulsory parameters. Energy savings therefore can be made only if the temperature of the product is kept as low as possible during manufacturing. This can be achieved by adding one of these phases at a much lower temperature (“hot/cold“ or “cold/hot“)!
By differentiating between hot and cold phases the product temperature can therefore be reduced to a much lower level compared to the hot/hot process as soon as the two phases are brought together. The lower mixing temperature results in a significantly smaller amount of energy being given off, which means a much shorter cooling and, in turn, process time.
This lecture offers a detailed description of the advantages of such a manufacturing process.

|Targeting Different Mechanisms for an Anti-aging Treatment
Wrinkles are the most outstanding feature of the unavoidable aging process. Repeated muscular contractions may originate permanent lines, known as expression wrinkles, which can be significantly minimised by modulating muscle contraction.
Muscle contraction involves a synapse, which develops between a motor neuron and a muscle fibre. When an electric impulse travels along the pre-synaptic cell, causes the release of the neurotransmitter acetylcholine (ACh) into the synapse, which diffuses to the post-synaptic dendrites and activates the acetylcholine receptors (AChRs). An action potential is created and muscle contraction takes place. There are two main strategies to modulate muscle contraction relaxing the muscle and helping to avoid the appearance of expression wrinkles: Pre-Synaptic and Post-Synaptic.
The pre-synaptic pathway involves the restrainment of the ACh release from the motor neuron whilst post-synaptic mechanism implies ACh –AChR binding limitation. A mimic of the N-terminal end of SNAP-25 competing with it for a position in the SNARE (SNAP REceptor) complex could modulate the formation of the complex, which is essential for the ACh release at the synapse. On the other hand, influencing on the modulation of AChR clusters formation in the post-synaptic membrane lessens muscle contraction. In both cases, muscle contraction is attenuated preventing wrinkle formation.
|Evaluation methods of cleaning performance of cleaners on hard surfaces
Project Leader Detergents
SGS Institut Fresenius
Preparations of test soilsFor determining the cleaning performance hard surfaces are soiled and aged under defined conditions. The selection of the test soil, weather greasy, mineral etc. depends on the type of cleaner undergoing the test.
The evaluation of product performance can either be done visually, gravimetrically or digital, for instance by means of CIE LAB measurements. Another possibility of evaluation is by means of digital image analysis.
Digital Image AnalysisA possible solution is the combination of the digital image processing with the wiping testing set. In addition a digital camera is installed above the wiping test set. The camera takes a picture during the wiping procedure after each stroke. With the help of the software the evaluation of the obtained data and picture is done.
After each wipe a contrast measurement and an intensity measurement of the remaining soil is determined. Hence the soil residues in percentage after each stroke can be determined for each track. With the obtained curve progression, the soil removal behaviour of the cleaner can be determined.
Experienced difficulties, advantage and requirements will be mentioned.
|Can you protect yourself against the tiger mosquito?
Product Specialist Cosmetics
The tiger mosquito (Aedes albopictus) is the world's most invasive mosquito. This mosquito is native to Southeast Asia and during last twenty years it has spread to Europe, the Americas, the Caribbean, Africa and the Middle East by international good transport and traveling. The tiger mosquito is less sensitive against climatic conditions than other species and the eggs can remain dry for months but still remain viable. The Asian tiger mosquito is an day-active aggressive human biter und is correlated to the hazards such as dengue, Chinkungunya and West Nile Virus.
Control measures against the tiger mosquito were established by many health authorities all over the world. But if control measures against the tiger mosquitos fail, insect repellents will provide personal protection against this disease vector.
Repellents are the substance or formulation that causes insects to make oriented movements away from its source. IR3535® is a personal, topical and synthetic repellent. It is marketed since more than 30 years in Europe. It represents a broad range of efficacy and field studies showing that IR3535® protects against the aggressive Tiger Mosquitoe up to 8 hours. IR3535 shows an excellent toxicological profile (classification as Bio-Pesticide in USA), is biodegradable and structural similarity with natural occurring ß-alanine.
Consequently, IR3535® provides excellent protection against the tiger mosquito and a wide range of insects. IR3535® combines the reliability of the natural repellent prototype ß alanine and the long term efficacy of the synthetically optimized repellent molecule. For all this reasons it is the preferred repellent active especially for children products.
Restorative natural active for damaged and weakened hair
International Sales Manager
Hair is the most powerful, exclusive and versatile accessory. There are many different options to change its shape and colour, but many of these treatments damage and weaken the fiber.
Keratrix™ is a multifunctional natural active obtained through selective hydrolysis from carob tree seeds. These oligopeptides are injected in a Matrix Plus, a natural three-dimensional network of amilopectyn that gets fixed on the hair fiber and delivers the active sequentially for a long-lasting effect.This exclusive technology of Provital allows a sustained release of the active.
Ex vivo tests performed on damaged tresses demonstrate that Keratrix™ has a protecting, strengthening and repairing effect on the hair, thus is specially recommended for weakened and damaged hair.
