Procédés de fabricationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : For over 35 years, Nature has been at the heart of the company business. Each SILAB active ingredient starts its history as a natural raw material, a source of active molecules capable of endogenously reactivating the skin's original resources.
For each development, SILAB guarantees a perfect mastery of natural, from the raw material up to the manufactured ingredient, corresponding to the Mastering natural® program specifications. The resulting active ingredient is natural with no compromise on safety, quality and efficacy. These 3 parameters are considered very early in each active ingredient development.
The neck and décolleté area symbolizes femininity and needs to be cosseted with the application of adapted beauty care. This fragile area, exposed to the effects of time, gravity and external stresses, shows evidence of the early signs of aging. However, there is a lack of care dedicated to this body area.
The aim of this study was to develop a natural active ingredient, which is safe, of high quality, with identified active molecules and effective on biological markers involved in the appearance of sagging neck and décolleté skin.Note de contenu : - I.

EnzymesUne enzyme est une protéine dotée de propriétés catalytiques. Pratiquement toutes les biomolécules capables de catalyser des réactions chimiques dans les cellules sont des enzymes ; certaines biomolécules catalytiques sont cependant constituées d'ARN et sont donc distinctes des enzymes : ce sont les ribozymes.
Une enzyme agit en abaissant l'énergie d'activation d'une réaction chimique, ce qui accroît la vitesse de réaction. L'enzyme n'est pas modifiée au cours de la réaction. Les molécules initiales sont les substrats de l'enzyme, et les molécules formées à partir de ces substrats sont les produits de la réaction. Presque tous les processus métaboliques de la cellule ont besoin d'enzymes pour se dérouler à une vitesse suffisante pour maintenir la vie. Les enzymes catalysent plus de 5 000 réactions chimiques différentes2. L'ensemble des enzymes d'une cellule détermine les voies métaboliques qui peuvent avoir lieu dans cette cellule. L'étude des enzymes est appelée enzymologie.
Les enzymes permettent à des réactions de se produire des millions de fois plus vite qu'en leur absence. Un exemple extrême est l'orotidine-5'-phosphate décarboxylase, qui catalyse en quelques millisecondes une réaction qui prendrait, en son absence, plusieurs millions d'années3,4. Comme tous les catalyseurs, les enzymes ne sont pas modifiées au cours des réactions qu'elles catalysent, et ne modifient pas l'équilibre chimique entre substrats et produits. Les enzymes diffèrent en revanche de la plupart des autres types de catalyseurs par leur très grande spécificité. Cette spécificité découle de leur structure tridimensionnelle. De plus, l'activité d'une enzyme est modulée par diverses autres molécules : un inhibiteur enzymatique est une molécule qui ralentit l'activité d'une enzyme, tandis qu'un activateur de cette enzyme l'accélère ; de nombreux médicaments et poisons sont des inhibiteurs enzymatiques. Par ailleurs, l'activité d'une enzyme décroît rapidement en dehors de sa température et de son pH optimums.

Visage -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The global facial care market offers numerous opportunities for enhancing the outward appearance of the facial area. For this, formulators have numerous cosmetic active ingredients at their disposal. However, a powerful active ingredient can only achieve the desired effect on the skin if it has the relevant bioavailability. The active ingredient must, therefore, be able to penetrate the skin efficiently and build up a specific concentration of the active ingredient there.
Glabridin is a natural whitening agent extracted from the liquorice root (Glycyrrhiza glabra). It intervenes in the biosynthesis of the skin’s own pigment (melanin) and lightens the skin. Its efficacy has been confirmed in numerous publications. However, it is difficult to formulate this active ingredient as it has a very low solubility in lipids. If attempts to incorporate the active ingredient homogeneously into the facial care formulation do not succeed, it will not achieve the relevant bioavailability. This is not the desired outcome given the high price of the active ingredient (five figure amounts per kg). Efficient, controlled penetration of the skin by Glabridin can be achieved by embedding Glabridin in submicron particles made of a semi-crystalline, unordered matrix of selected liquid and solid lipids. Furthermore, the lipid particles help to repair a damaged skin barrier by adhering to the skin thanks to effective adhesion. This adhesion offers the added advantage of prolonged release. The particles are stabilised in suspension and remain in a solid state even at skin temperature.Note de contenu : - The success of whitening products

Gomme de guarLa gomme de guar est extraite de la graine de la légumineuse Cyamopsis tetragonoloba, où elle sert de réserve d'aliments et d'eau.
La gomme de guar est composée principalement de galactomannane, une fibre végétale soluble et acalorique. Le galactomannane est un polymère linéaire composé d'une chaine de monomères de mannose ((1,4)-beta-D-mannopyranose) auxquelles sont ramifiés par un pont 1-6 une unité de galactose. Le ratio entre le mannose et le galactose est de 2 pour 1, ainsi en moyenne une unité de galactose est ramifié tous les deux mannose sur la chaine. Par comparaison, il est de 4 pour 1 pour la gomme de caroube et 3 pour 1 pour la gomme tara.
La gomme de guar est un additif alimentaire (E4124) largement utilisé dans l'industrie agro-alimentaire. Elle permet notamment d'alléger certaines préparations en remplaçant le rôle de l'amidon, de sucres ou de matières grasses. La gomme de guar est utilisée comme épaississant, stabilisant et émulsifiant dans les aliments grâce à sa texture uniforme et ses propriétés pour former des gels. Elle peut être utilisée dans les sauces, soupes, crèmes glacées et sorbets, produits de boulangerie et de pâtisserie, poudres, etc.
Gomme de xanthaneLa gomme xanthane est un polyoside obtenu à partir de l'action d'une bactérie, la Xanthomonas campestris. Elle est soluble à froid et est utilisée comme additif alimentaire sous le code E415 pour ses propriétés épaississantes et gélifiantes afin de modifier la consistance des aliments.
Le xanthane est l'un des exopolysaccharides excrétés par divers microorganismes du sol (bactéries notamment). Il joue un rôle important, à l'échelle moléculaire, dans la formation et la conservation des sols3, tout comme le dextrane, le rhamsane ou les succinoglycanes.

SurfactantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The use of microplastics in cosmetic surfactant formulations represents an increasing ecological problem. As a natural alternative the polymers examined in this work, guar gum, cationic guar gum and xanthan gum can be used as thickening agent or as stabiliser of emulsions. The rheology changed by the polymer-based gelling agent also influences the foam properties as well as the stability of the product. This is why the compatibility of several natural polymers were analysed with two different surfactant systems (anionic non-ionic surfactant system and amphoteric non-ionic surfactant system) for the specific application parameters such as the foaming behaviour, the foam stability and the foam structure and its aging. The influence of electrolytes was also analysed on the example of sodium chloride (NaCI) and then compared with the foam properties of the polymer-based gelling agent. The foam analytics was carried out using the Dynamic Foam Analyzer DFA100 (KRÃœSS GmbH). In doing so, the recently released Foam Flash Method is presented and used, a method that is particularly good for the analysis of the foaming behaviour of strongly foaming surfactant solutions.
The addition of the polymer-based gelling agent to the surfactant systems had a substantial improvement to the foam formation and the foam stability, and significant influence on the foam structure. The strongest effects were shown by xanthan gum. It is also shown that the influence of individual gelling agent on the foaming behaviour depends strongly on the characteristics of the surfactant system.Note de contenu : - INTRODUCTION : Foam in surfactant solutions

There is scarce data that touches on the effects of BL on human skin. Moreover, the data available so far has been performed on basic cellular models that are far from the complexity of human skin. This study focuses on the identification of the BL induced damage using 3D models. We found that direct BL exposure to the skin generates ROS leading to oxidative stress marker generation including protein carbonylation, nitrotyrosine, 4-hydroxynonenal. In addition, the expression of matrix metalloproteinase-1 which is responsible for extracellular matrix degradation during chronological aging and photoaging processes is increased. These data show that blue light emitted by electronic devices affect skin health and may be involved in premature aging.

Lactique, AcideL'acide lactique est un acide organique qui joue un rôle dans divers processus biochimiques. Un lactate est un sel de cet acide. Contrairement à ce que peut laisser penser son nom, l'acide lactique n'est pas présent uniquement dans le lait, mais également dans le vin, certains fruits et légumes, et dans les muscles.
L'acide lactique est un acide alpha hydroxylé, sa formule chimique est C3H6O3 et sa structure se reflète dans son nom systématique, l'acide 2-hydroxypropanoïque.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Synthetically produced biocides are effective and widely used in low-pH, rinse-off household and personal care applications to preserve products. Isothiazolinones, such as benzisothiazolinone (BIT) and methylisothiazolinone (MIT), are an important biocide family, commonly used as a preservative in in-can, wash-off household and personal care applications. But growing concerns over the years about their safety, particularly in fabric conditioning and cosmetic applications where allergenic chemicals stay in contact with people’s skin for prolonged periods of time, has led to tighter regulatory restriction on their use. New attitudes towards chemicals has also sparked consumer demand for more sustainable, eco-friendly products. This has placed pressure on formulators to find safer and more sustainable biocide alternatives. Note de contenu : - Increasing restrictions on biocide use

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The EC-cosmetics regulation (1223/2009) defines requirements for the adequate quality and safety of cosmetic products. These requirements include microbiological aspects. Accordingly, microbiological objectives have to be fulfilled in various processes. These objectives can only reliably be reached by means of quality management systems (QMS), which cover all relevant processes. Such a system is presented by the GMP-guidelines (ISO 22716) which is part of the cosmetics regulation. Since microbiological objectives are also located in processes which are not in the scope of the GMP-guidelines (development, up-scaling, safety assessment) the system approach must be enlarged to include all microbiological activities: the MQM (microbiological quality management) is used as QMS. In this way, general system targets, which are covered for instance in the GMP-guidelines, can also be also applied for other processes, and thereby, microbiological quality and safety targets can be controlled in a holistic way. The system application (GMP and MQM) also allows for the systematic microbiological risk management which provides the basis for the safety statement. The MQM-system is used in the microbiological area as weight-of-evidence approach for the data used for the safety statement. The text describes how system elements of GMP and then also of the MQM-system are employed in practice as well as their importance for the microbiological quality and safety of cosmetic products.

Tests microbiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Microbiological issues play a central role in the quality assurance of cosmetics. This requires appropriate microbiological expertise and know-how. In addition to microbiological training, this microbiological expertise can also be acquired through professional experience, literature, further training and seminars. Basic microbiological knowledge is most helpful.
On the homepage of the DGK (Deutsche Gesellschaft für Kosmetik) you can find two new documents from the group "Microbiology and Industrial Hygiene", which provide valuable assistance regarding the microbiological safety and harmlessness of your products (https://web.dgk-ev.de/publikationen-fg2/).
The basic requirements for microbiological testing are explained in one of the documents in the form of answers to individual questions.
If you have more questions, please do not hesitate to send them to Mrs. Joelle Nussbaum (joelle.nussbaum@bav-institut.de). The topics will be discussed an answered by the working group of the DGK.Note de contenu : - Why do basic requirements for the performance of microbiological tests of cosmetics have to be fulfilled ?
- Is it necessary to test my product from a microbiological point of view ?
- What is a low-risk product ?
- What needs to be considered during microbiological sampling ?
- How often do i have to test my product ?
- Which method should i use for the microbiological examination ?
- May I carry out the tests internally ? If so, what requirements need to be considered ?
- What has to be considered when subcontracting microbiological analysis for sample release ?
