摘要:
The invention describes the use of micronized organic UV filters for preventing tanning and for lightening human skin and hair, and their use in cosmetic and pharmaceutical formulations. The micronized UV filters used according to the invention cover a broad UV spectrum and therefore have excellent sunscreen properties.
摘要:
The invention describes the use of a nanodispersion, which comprises: a) a membrane-forming molecule, b) a co-emulsifier, c) a lipophilic component, and d) a water-soluble ingredient sensitive to oxidation in cosmetic end formulations, the nanodispersion being obtainable by (α) mixing the components (a), (b) and (c) until a homogeneous liquid is obtained (so-called nanodispersion pre-phase), and (β) adding the water or aqueous phase (discontinuous phase) which contains the water-soluble ingredient and optionally the non-aqueous polar organic solvent to the liquid obtained in step (α). Component (d) is preferably ascorbic acid or vitamin C.
摘要:
A cosmetic or pharmaceutical composition is provided comprising: a) 0.001 to less than 0.2% by weight, based on the weight of the total composition, of a scleroglucan having a mean molecular weight of 1×106 to 12×106; b) a cosmetically or pharmaceutically acceptable carrier; and, optionally, c) lactic acid, a lactate and/or pentanediol. The composition shows advantageous effects, such as moisturization of skin or mucosa, and has an antiaging and revitalizing effect on the skin. When combined with a certain bactericide as explained in claim 1, compositions containing native polysaccharides of the glucan class in general, especially of the scleroglucan as of component a), are well suitable to reduce the number of bacteria in mucosal or oral environments and minimise adhesion, while retaining a pleasant feeling on the mucosa or gingiva. Plaque thus can be efficiently prevented or removed.
摘要:
The use is described of compositions comprising (a) (−)-guaiol, (b) further skin-lightening active substance(s) and, optionally, (c) one or more UV-A and/or UV-B absorbers as melanogenesis inhibitors and for skin-lightening.
摘要:
Formulations for cosmetical or pharmaceutical use contain an antioxidant in encapsulated form and a cosmetically or pharmaceutically acceptable carrier. The antioxidant is selected from carbon bridged hindered phenoles, ester bridged hindered phenoles, amide bridged hindered phenoles, lactones of hindered phenoles, sterically hindered oxylamines and sterically hindered hydroxylamines. The encapsulated antioxidant is of high activity and suitable to protect a further active ingredient, e.g. oxidizable natural substances, vitamins, fragrances, and extracts from plants fungi, algae or animals, from premature degradation, especially when coencapsulated together with the ingredient. The formulations are useful inter alia for the preparation of a cosmetical or pharmaceutical skin care or skin delivery formulation, injectable solution, infusion solution, eye drop, drinking solution, a dietary or enriched food, an oral care formulation, drinking gargles, in-halants, or as a food additive.
