Iodopropynyl butylcarbamateconservateurs autorisés en cosmétique, établie par la réglementation européenne.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Preservation is a vital part of any personal care formulation. We require preservatives to protect our products from the effects of bacterial, yeast and fungal growth. Selecting the correct system to perform this task is not a simple process — many factors will need to be considered before the correct choice can be made. The system must not only be robust enough to ensure that a finished product is sterile when first made, but also that it minimises risk of contamination right up to the expiry date.
In this paper, we will discuss the challenges faced by cosmetics chemists when evaluating preservation options. Regulatory pressures, consumer perception and the abundance of new and conflicting studies of varying degrees of scientific credibility make preservation selection increasingly complex. We will discuss recent trends, some of which are promising, while others, such as non-preservative alternatives, may actually pose greater risk. We will also explore the advantages of IPBC (iodopropynyl butylcarbamate) as a preservative, whether used as the sole active or as part of broad-spectrum blends, some of which offer unique benefits in the marketplace.Note de contenu : - Personal care preservation background

Camélia du JaponCamellia japonica, communément appelé camélia, est une espèce d'arbustes.
C. japonica aurait été rapporté du Japon par les marchands portugais au XVIe siècle, puis à plusieurs reprises par les Britanniques en provenance de Chine, à la fin du XVIIIe siècle.
Des tests in vitro laissent penser que Camellia japonica pourrait avoir des vertus protectrices de la peau (encore non comprise en 2019) contre la pollution de l'air. (Wikipedia)

Stress oxydatifIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Hair loss is caused by various factors. Impacts of these factors are often overlapped and intensified. Currently, mitigation of hair loss is being studied by proliferating dermal papilla cells (DPCs) and inhibiting deleterious factors such as dihydrotestosterone (DHT) and oxidative stress on hair growth. Camellia japonica (C. japonica) fruit shell is a discarded part. Its biological activity remains to be elucidated. In this study, we investigated the capacity of C. japonica fruit shell extract (CJFSE) for hair loss mitigation.
- Methods : MTT assay, spheroid culture and quantitative RT-PCR were performed to observe the proliferative effect of CJFSE on hair follicle dermal papilla cells (HFDPCs). Effects of CJFSE on DHT-induced hair loss were confirmed by Dkk-1 ELISA, β-galactosidase (β-gal) and 5α-reductase activity assay. In addition, effects of CJFSE on oxidative stress were confirmed through DPPH and ROS production assays.
- Results : CJFSE increased the proliferation and spheroid size of HFDPCs. Expression levels of VEGF-A, Wnt-1, c-Myc and Cyclin D1 were upregulated by CJFSE. CJFSE also suppressed 5α-reductase activity and DHT-induced decrease in cell proliferation, Dkk-1 secretion and β-gal activity. Moreover, CJFSE showed DPPH scavenging activity and ameliorated hydrogen peroxide-induced ROS production and β-gal activity. Finally, gallic acid and protocatechuic acid were observed in CJFSE through HPLC analysis.
- Conclusion : CJFSE has the potential to alleviate hair loss by promoting hair cell growth and suppressing effects of DHT and oxidative stress on hairNote de contenu : - MATERIALS AND METHODS : Cell culture - Preparation of Camellia japonica fruit shell extract - Cell viability assay - Cell proliferation assay - Spheroid culture of HFDPCs - Quantitative real-time PCR - Western blot analysis - DHT-induced senescence - 5α-reductase

Stress oxydatifIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The skin, as the largest organ of the body, plays an important role for our health. As a protective shield, it is constantly exposed to external environmental influences and stress. In order to maintain and support this protective barrier, numerous active ingredients are used in cosmetics. A major group of these are antioxidants, which can neutralize stress factors in the skin.
Astaxanthin, which is the strongest natural antioxidant belonging to the carotenoid family, does this particularly well due to its special molecular structure. Due to its unique structure of hydrophilic and lipophilic components, it can act more effectively in the lipid bilayers of the skin than most other antioxidants.
Especially in the field of light-induced oxidative stress, triggered by UV radiation and infrared as well as blue light, in vitro and in vivo studies with the active ingredient AstaCos® OL50 from BDI-BioLife Science have shown that astaxanthin has a strong protective effect.
Numerous research studies conclude that astaxanthin can also improve overall skin health, and provide comprehensive protection against oxidative stress. Possible uses range from anti-aging products to formulations that combat the effects of UV exposure and light, to an active ingredient in sunscreen products and face creams.Note de contenu : - The molecular structure of astaxanthin

Stress oxydatifIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The human skin is a complex and multifunctional organ that protects the body from external physical, chemical and infectious attacks. It is not only a barrier shielding of the human body from extrinsic factors. It also functions as a sensory organ, prevents the organism from losing water through evaporation and is the site of immunological defence mechanisms and bio-synthesis (e.g. of vitamin D3).
In order to fulfil its various functions, a good skin health is important. An essential indicator of the skin’s health condition is its visible appearance. A firm, youthful-looking skin with a radiant complexion and natural warm glow is not only a desirable feature of beauty, but also indicates a good state of health.
However, intrinsic and extrinsic influences like lack of sleep, a poor nutrition, stress, air pollution or solar radiation can cause the skin‘s radiance to fade. Both factors promote an overproduction of reactive oxygen species (ROS) and lead to a state of oxidative stress, a major cause of skin damage and premature skin ageing.Note de contenu : - Oxidative stress and its influence on skin health
- Antioxidants against skin deterioration
- Astaxanthin - the red diamond amongst antioxidants
- A powerful red diamond for a healthy radiant complexion
