ElastasesEn biologie moléculaire, les élastases sont des enzymes produites par certains animaux (dont les mammifères), appartenant à la classe des protéases.
Exclusivement produites dans le pancréas, elles sont diffusées dans le corps où elles ont un rôle immunologique (attaque des parois externes de bactéries) et où elles catalysent l’hydrolyse de l’élastine, une fibre élastique qui - avec le collagène - détermine les propriétés mécaniques du tissu conjonctif.

Toxicologie cellulaireIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Coenzyme Q10 (CoQ10) is a major ingredient in skin care products because of its anti-wrinkle effects, although it has some side effects especially at higher amounts. In this study, we compare the anti-wrinkle related properties of CoQ10 and a proprietary Commiphora mukul gum resin (guggul) and triheptanoin preparation (GU-TC7). GU-TC7 is prepared with a supercritical CO2-co-solvent extraction with ethanol, standardized to 2% guggulsterones and triheptanoin, a triglyceride composed of three 7-carbon fatty acids. Treatment of CCL-110 skin fibroblasts with GU-TC7 demonstrates a mild proliferative effect compared to CoQ10 and increased type I collagen synthesis. Additionally, GU-TC7 inhibited matrix metalloproteinase-1 (MMP-1) expression in a dose-dependent manner at 20–100 ?g mL?1 and inhibited human elastase expression by more than 50% as compared to no elastase inhibition with CoQ10 treatment. These results suggest that GU-TC7 possesses properties that are applicable to the treatment of wrinkles and may be considered for its further evaluation in skin care products.

pH
PolyélectrolytesIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : pH is used as a control for charge throughout the collagen or leather structure. This directly influences the penetration and fixation of materials within the matrix. However, the charge of collagen/leather depends on the relationship between pH and pI (lEP). ln practice, the lower the pH in relation to the pI, the greater the positive charge of the collagen/leather, the deeper the penetration of positively charged (cationic) products, and the slower or less secure their fixation. Conversely, the higher the pH in relation to the pI, the greater the negative charge of the collagen/leather, the deeper the penetration of negatively charged (anionic) products, and the slower or less secure their fixation. Moreover, cationic, anionic and neutral materials, which interact with charges on collagen/leather, can also influence pL pI is central to many mechanisms of chemical penetration and fixation, but unfortunately it is difficult to measure. Nevertheless, the direction that chemicals shift the pI, and the effects that this has on leather charge, are essential to an understanding of wet end collagen/leather chemistry.
