摘要:
The present invention provides a bacillus sp. having a deposit access number of CGMCC NO. 5744 and a hyaluronidase produced by the bacillus and the amino acid sequence of the hyaluronidase is shown in SEQ ID NO: 2. The present invention further relates to a process for preparing oligomeric hyaluronic acid or salts thereof or low-molecular-weight hyaluronic acid or salts thereof by using the bacillus or the hyaluronidase produced thereby. The produced oligomeric hyaluronates or low-molecular-weight hyaluronates have advantages such as good transdermal absorption ability, high purity, no cytotoxicity, potent antioxidant ability. The present invention also provides use of the bacillus having a deposit access number of CGMCC NO. 5744, or the hyaluronidase, oligomeric hyaluronates or salts thereof, low-molecular-weight hyaluronates or salts thereof produced by the bacillus in the fields of osmetics, food products and medicines.

摘要:
The present invention relates to an extract of Dionaea muscipula and a composition comprising such an extract for cosmetic treatment of the skin and skin appendages such as sebaceous glands, hair and nails especially skin changes due to accelerated or chronological aging e.g. wrinkles loss of firmness and elasticity, and increased pigmentation. It also regards the use of such an extract for the preparation of a composition for cosmetic treatment. The composition may comprise further substances active against skin changes due to accelerated or chronological aging e.g. wrinkles loss of firmness and elasticity, and increased pigmentation. Especially it may contain an extract from Cymbidium erythraeum. It may also comprise bases, cosmetic pigments, UV filters and/or UV scattering agents. The scope of the invention also covers a method for cosmetic treatment of the skin, especially skin changes due to accelerated or chronological aging e.g. wrinkles loss of firmness and elasticity, and increased pigmentation wherein a persons skin is treated with a composition comprising an extract from Dionaea muscipula. Such a composition may also contain an extract from Cymbidium erythraeum.
摘要:
This invention relates to peptide compounds of general formula (I) R1-(AA)n-X1-X2-X3-Asp-Leu-Lys-Lys-X4-X5-(AA)p-R2. Said peptide compounds have an action on the SCF/c-Kit signaling pathway and thus make it possible to protect skin pigment structures from external stresses. In addition, this invention relates to a cosmetic or pharmaceutical composition comprising at least one peptide of general formula (I), in a physiologically acceptable medium, and its use for attenuating age-related pigmentation defects and the effects of photoaging on the skin. The invention finally relates to various cosmetic treatment methods using said peptides according to the invention.
