Although the negative effects of particulate matter on the respiratory system are well documented, until now their impact on the skin has not been investigated in depth. Working on the assumption that keeping particulate matter off skin is the first line of defense against pollution-induced damage, BASF has developed a novel standardized test method to assess the effects of typical cosmetic ingredients, i.e. polymers, emulsifiers, and emollients, on the adhesion and removability of polluants. The findings have been used to create formulations that exhibit clear anti-adhesion and rinse-off (removability) effects.

A novel epigenetic-regulating active for repairing weakened and damaged skin / Snow Hsieh in SOFW JOURNAL, Vol. 145, N° 3 (03/2019)  

[article]  inSOFW JOURNAL > Vol. 145, N° 3 (03/2019) . - p. 16-22 Titre : A novel epigenetic-regulating active for repairing weakened and damaged skin Type de document : texte imprimé Auteurs : Snow Hsieh, Auteur ; Kuan-Yi Yeh, Auteur Année de publication : 2019 Article en page(s) : p. 16-22 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Anti-inflammatoires Biomolécules actives Cicatrisation Cosmétiques Dermo-cosmétologie Peau -- Soins et hygiène Régénération (biologie) Index. décimale : 668.5 Parfums et cosmétiques Résumé : Skin lesions not only have negative social and psychological ramifications on both men and women but may also cause irritation, discomfort, burn and even pain. Uneven skin tone, pigmentation, fine lines and wrinkles as well as scaling and flaky skin are all considered signs of imperfect skin, but one of the more permanent types of skin damage is skin lesions that may potentially lead to severe scarring. These scars are typically punctured deep and can only be removed through a series or combination of clinical procedures. Even to a less severe extent, skin lesions may leave skin with temporary pigmentation, marks and blemishes. If appropriate treatment is not applied on the damaged skin site, skin lesions, especially those resulting from inflamed acnes, may leave large surface of skin rough and bumpy. Besides naturally occuring skin damage, there are numerous clinical procedures, such as laser treatment, skin needling or microdermabrasion, aiming at weakening or destroying the stratum corneum or slightly deeper skin layer to trigger the innate rejuvenating and healing mechanism of skin. This post-procedure skin undergoing dermabrasion or laser treatment is slightly inflamed on the surface and typically sensitive, as the skin barrier was dwindled and enfeebled. Regardless of the perpetual tendency for human to pursue beauty defined by flawless skin or the contemporary concept of wellness and healthy living, the marks and scars as well as the weakened, damaged or disfigured surface left on the skin instigate negative psychological impacts and sequelae in the forms of embarrassment, impaired self-image, low self-esteem or even anxiety. Therefore, soothing and repairing weakened skin as well as damaged skin has been an important area for cosmetic development.

Capacitive contact imaging - New clinical sreening method for aluminum free products / Britta Malcher in SOFW JOURNAL, Vol. 145, N° 3 (03/2019)  

[article]  inSOFW JOURNAL > Vol. 145, N° 3 (03/2019) . - p. 28-34 Titre : Capacitive contact imaging - New clinical sreening method for aluminum free products Type de document : texte imprimé Auteurs : Britta Malcher, Auteur ; Marianne Brandt, Auteur ; Gunja Springmann, Auteur ; Stephan Bielfeldt, Auteur ; Klaus-Peter Wilhelm, Auteur Année de publication : 2019 Article en page(s) : p. 28-34 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Aluminium L'aluminium est un élément chimique, de symbole Al et de numéro atomique 13. C’est un métal pauvre, malléable, de couleur argent, qui est remarquable pour sa résistance à l’oxydation13 et sa faible densité. C'est le métal le plus abondant de l'écorce terrestre et le troisième élément le plus abondant après l'oxygène et le silicium ; il représente en moyenne 8 % de la masse des matériaux de la surface solide de notre planète. L'aluminium est trop réactif pour exister à l'état natif dans le milieu naturel : on le trouve au contraire sous forme combinée dans plus de 270 minéraux différents, son minerai principal étant la bauxite, où il est présent sous forme d’oxyde hydraté dont on extrait l’alumine. Il peut aussi être extrait de la néphéline, de la leucite, de la sillimanite, de l'andalousite et de la muscovite. L'aluminium métallique est très oxydable, mais est immédiatement passivé par une fine couche d'alumine Al2O3 imperméable de quelques micromètres d'épaisseur qui protège la masse métallique de la corrosion. On parle de protection cinétique, par opposition à une protection thermodynamique, car l’aluminium reste en tout état de cause très sensible à l'oxydation. Cette résistance à la corrosion et sa remarquable légèreté en ont fait un matériau très utilisé industriellement. L'aluminium est un produit industriel important, sous forme pure ou alliée, notamment dans l'aéronautique, les transports et la construction. Sa nature réactive en fait également un catalyseur et un additif dans l'industrie chimique ; il est ainsi utilisé pour accroître la puissance explosive du nitrate d'ammonium. Antiperspirants Gravimétrie (chimie analytique) Imagerie (technique) Sels d'aluminium -- Produits de remplacement Transpiration -- analyse Index. décimale : 668.5 Parfums et cosmétiques Résumé : Althrough a natural function of the skin, perspiration and the odor it produces is considered offensive in many cultures, and consequently products addressing this problem are in high demand. Antiperspirants and most deodorants are normally formulated with aluminum salts. However concerns over environmentaly safety, health and wellbeing are driving innovation in new directions. A wide appreciation of the effects of antiperspirants and deodorants on the skins natural microbiome is taking centre stage, and the desire for more natural microbiome friendly products is leading to new development, both in formulations and performance testing methods. In order to investigate the efficacy of antiperspirants at the early stages of developments, a screening test based on the gravimetric sweat determination, by appyling cotton pads to harvest the sweat, is preferably used. However, this standard test does not work with all aluminum-free antiperspirants, especially those containing film forming actives where the contact with cotton pads may lead to a measurement bias. In the present work we describe a new screening method using Capacitive Contact Imaging in which the sweat reducing effect of a new generation of non-plug forming actives can be evaluated without application of pads to sample the sweat. In evaluating the method, a differentiation between the effect of different substances was observed. In summary, Capacitive Contact Imaging with appropriate image analysis is a reproductible and innovative approach for the efficacy of non-aluminum containing, as well as aluminum containing antiperspirants, especially for those for which gravimetric methods fail to produce accruate results.

As an answer, several types of estolides were synthetized by ingredient manufacturers, starting from vegetable fatty acids. Two main ways of synthesis of these intermolecular esters can be considered, depending on the raw materials. We developed a new estolide ester, based on castor oil, engineered with as few transformations as possible, showing a great versatility in applications for cosmetic formulators, and a high degree of Naturality. The performances of this innovative polymer ingredient, dedicated to haircare, skincare, and lipcare, were screened through a sensorial panel and instruments. Our estolide ester brings a broad range of properties as texturizing or film-forming agent, and moisturizer. It also shows interesting values as a pigment disperser. During application on hairs, skin, or lips, this ester of estolide will give high protective properties from air pollution. The ingredient we tuned showed to be fully biodegradable, and its NOI (Natural Origin Index) is 87%. Our commitment to Naturality determined our scientific approach, and our technology allowed us to manufacture this ester of estolide with unique performances and a reduced environmental footprint.

This system is directly responsible of the human microbiome health. The new active QUORANONI (INCI name Morinda Citrifolia Cell Culture Lysate), hacks these bacteria communication signals, avoiding the harmful attack of microbes on the skin, that causes acne and other skin conditions. Developed from stem cells from the Noni plant, the ingredient is a metabolome rich in anti-Quorum Sensing molecules, specially designed to act against bacterial dysbiosis, blocking the microbial communication signals in a natural way, stopping the development of virulence and perfecting, at the same time, the skin appearance. The active doesn't contain antibiotics, thus avoiding the potential development of microbial resistance, and it is also bacteriostatic, maintaining a healthy microbial balance. A full panel in vitro and in vivo studies was carried out, demonstrating these claims, and the high efficacy of the active against acne.

Soil release polymers enhancing soil removal with eco-friendly products for polyester fabrics in the washing process / Karolin Rouette in SOFW JOURNAL, Vol. 145, N° 3 (03/2019)  

[article]  inSOFW JOURNAL > Vol. 145, N° 3 (03/2019) . - p. 54-56 Titre : Soil release polymers enhancing soil removal with eco-friendly products for polyester fabrics in the washing process Type de document : texte imprimé Auteurs : Karolin Rouette, Auteur Année de publication : 2019 Article en page(s) : p. 54-56 Langues : Anglais (eng) Catégories : Détergents Formulation (Génie chimique) Polyesters Polymères Produits nettoyants Textiles et tissus -- Lavage Textiles et tissus synthétiques Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Synthetic fabrics of polyesters improve in comparison to cotton the durability of apparels and household linen but lead due to their hydrophobic characteristics to problems of removal greasy soil which have a high affinity for hydrophobic synthetic fabrics improving their adhering to the hydrophobic fiber. The hydrophilic cotton fiber absorbs, by contrast, water quite well in the washing process, which makes the soil and stains easier to remove. By physical absorbing of Repel-O-Tex soil release soil polymers (SRP) interactions between synthetic fabric and greasy soil are reduced and their surface hydrophilicity is enhanced making stain removal easier. Already at the first wash a strong adhesion of soil particles on the fibers is prevented and in the second the soil removal becomes much easier. In the following washing cycles the washing effect will be enhanced by obtaining the whiteness of the fibers without a build-up effect on the surface.
