Provided herein are biopolymers comprising repeating polysaccharide units, preparations of biopolymers, and topical compositions comprising biopolymers, as well as methods of use.

The present invention concerns a method for the cosmetic caring of the skin and/or mucosa, comprising applying a postbiotic composition comprising at least one postbiotic and at least one bacteriocin and/or endolysin, wherein said postbiotic is preferably a bacterial lysate preferably obtained from bacteria heterologously expressing said at least one bacteriocin and/or endolysin and wherein said postbiotic and said at least one bacteriocin and/or endolysin have a synergistic effect in the cosmetic caring method.

The disclosure describes an oil-in-water composition for skin external application using a gel of crosslinked hyaluronic acid or a salt thereof and having a sherbet-like texture and feeling of use. The composition of the disclosure comprises the gel particles of crosslinked hyaluronic acid or a salt thereof and emulsion particle having a specific particle size distribution of D(0.5) in an aqueous phase and an oil phase, respectively, so that the composition has a particulate feeling such as sherbet, mashed potato or meringue while having a fluffy appearance or texture, and also provides a refreshing feeling of use when applied, and is easy to clean by comprising the aqueous phase as an outer phase.

Lactobacillus sakei is provided, wherein the Lactobacillus sakei is Lactobacillus sakei TCI147 with an accession number of DSM 33913. A method for spermidine production with Lactobacillus sakei or metabolites thereof is provided, wherein the Lactobacillus sakei is Lactobacillus sakei TCI147 with an accession number of DSM 33913.

The invention relates to a dispersion containing at least one rhamnolipid derivative and also to the use of the rhamnolipid derivatives as emulsifier or dispersing aid.

A cosmetic composition including a yeast hydrolysate and to the use thereof in cosmetics, for promoting moisturization of the skin and/or protecting human skin against drying out and/or improving the barrier function and/or for an anti-ageing effect. The yeast hydrolysate is obtained by a process that includes solubilization of the yeast in water, enzymatic hydrolysis, separation of the soluble and insoluble phase and recovery of the soluble phase, enzymatic inactivation, and optionally concentration and sterilizing filtration.

The present invention relates generally to cosmetic compositions and methods that can be used to increase skin hydration, increase adenosine triphosphate (ATP) production in skin, increase antioxidant capacity of skin, reduce glycation of skin, or a combination thereof. In particular, topical application of the compositions to skin increases adenosine triphosphate (ATP) production in skin by at least 10%, increases antioxidant capacity of skin, and/or reduces glycation of skin by at least 50%. In particular, the compositions can include Chamomilla recutita (Matricaria) flower extract, Vitis vinifera (Grape) seed extract, hydrolyzed sodium hyaluronate, Natural Moisturizing Factors (NMF), and optionally carnosine.

A topical skin moisturizing composition comprising: (a) one or more phospholipids; (b) a plurality of demulcents; (c) one or more polymeric moisturizing agents; (d) one or more preservatives; (e) one or more vitamins; and (f) an aqueous vehicle. The moisturizing composition can have an osmolality in the range of 80 mOsm/kg to 500 mOsm/kg. The composition is configured for use on the face and, particularly for application on and around the delicate eye area including the eyelids.

A composition is disclosed that includes pure silk fibroin-based protein fragments that are substantially devoid of sericin, wherein the composition has an average weight average molecular weight ranging from about 17 kDa to about 38 kDa, wherein the composition has a polydispersity of between about 1.5 and about 3.0, wherein the composition is substantially homogeneous, wherein the composition between 0 ppm to about 500 ppm of inorganic residuals, and wherein the composition includes between 0 ppm to about 500 ppm of organic residuals.

Disclosed is a method for moisturizing skin in need thereof, the method comprising topically applying to the skin a composition that includes effective amounts of an extract from Echinacea purpurea, an extract from Silybum marianum, and glycerin, wherein topical application of the composition activates human cannabinoid receptor type 2 and inhibits fatty acid amide hydrolase activity in the skin and treats the skin.
