CO-EMULSIFICATION COMPOSITION CONTAINING VARIOUS EMULSIFICATION PARTICLE SIZES AND METHOD FOR PREPARING SAME
Disclosed are: a co-emulsified composition containing different emulsification particle sizes; and a method for preparing the same. The co-emulsified composition contains an amphipathic anisotropic power and a surfactant, thereby allowing emulsification particles with different sizes to coexist in one dosage form, and thus a co-emulsified composition can be provided that simultaneously implements two or more feelings of use or physical characteristics.
SKIN TREATMENT METHODS AND COMPOSITIONS FOR TRANSDERMAL DELIVERY OF ACTIVE AGENTS
Disclosed are stable, non-irritating, skin treatment active agents containing formulations and delivery systems for topical application to the skin. The disclosed topical formulations and delivery systems provide controlled, gentle release of the active agents into the skin for the treatment of amenable skin conditions as well as for improvement of aesthetic skin properties. Also provided are methods for the formulation, manufacture and use of the disclosed formulations and delivery systems.
Process for producing microemulsion system of nano essential oil
The invention relates to the process for producing an microemulsion system of nano essential oil, the process comprising the following steps: (i) preparing a dispersed phase of essential oil; (ii) preparing of a carrier formed from a mixture of diethylene glycol monoethyl ether and lecithin; (iii) adding the carrier to the dispersed phase while keeping the dispersed phase temperature between 60 and 100° C. after addition of the carrier, while simultaneously stirring under vacuum; then pass the entire solution mixture through the system of high-pressure homogeneous machine integrated dispersion nozzle; (iv) adding the solution mixture obtained in step (iii) to Capryol 90 while keeping the mixture temperature between 60 and 100° C., and stirring at a rate ranging from 400 up to 800 rpm under vacuum; (v) cooling the mixture, homogenizing the mixture by ultrasonication to achieve a droplet size smaller than 100 nm.
Composition in the form of nano or micro emulsion or with lamellar structure
The present invention relates to a composition, preferably a cosmetic composition, comprising: (a) at least one oil; (b) at least one polyglyceryl fatty acid ester, preferably with a polyglyceryl moiety derived from 2 to 6 glycerins; (c) at least one compound selected from the group consisting of resorcinol and resorcinol derivatives; and (d) water. The composition according to the present invention can be in the form of a nano- or micro-emulsion, or can have a lamellar structure or a lamellar phase, with better transparency and stability.
Approaches for improving skin hydration and moisturization
The present disclosure generally relates to approaches for improving water absorption and retention by the skin's surface. In particular, the disclosure provides compositions and methods for preparing mixtures comprised of ethoxylated oils and water or mixtures comprised of micro or nano emulsions and water, which provide enhanced skin hydration or moisturization to a subject.
Aqueous oil in water micro-emulsions, and product
Disclosed are clear, aqueous perfume compositions which are free of ethanol. There is further provided a perfume composition which is clear, provides a good skin feeling, and good air drying properties on the skin.
HAIR CARE COMPOSITIONS COMPRISING CATIONIC COMPOUNDS, STARCH, AND SILANE COMPOUNDS
Disclosed are compositions for treating and conditioning keratinous substrates, comprising a cationic agent comprising quaternary ammonium compounds; a modified starch; silane compounds, a cationic vinylpyrrolidone polymer and water. Also disclosed are methods treating and conditioning keratinous substrates using the composition.
MICROEMULSIONS AND METHODS OF USE
Compositions are described that include an oil, a surfactant, and optionally a charged polymer complex, where the composition may also include an aqueous phase to provide a microemulsion. Methods of manufacturing the compositions are also described, along with methods of using the compositions in home care and personal care.
Durable skin sanitizers containing water stable antimicrobial silanol quaternary ammonium compounds
This invention is a method of eliminating the number of microorganisms on the surface of skin, hair or nails, by contacting these surfaces with a water stable, antimicrobial silanol quaternary ammonium compounds (SQACs) and the trisilanol, polysiloxanol and water soluble polysiloxane derivatives thereof. The stabilizing agent is selected from a list of volatile, antimicrobial, naturally occurring, renewable phytochemical essential oils and extracts that easily form crystal clear microemulsions when water is added to the concentrated SQAC/essential oil mixture. These non-foaming oil in water microemulsions have excellent long term storage stability, are freeze/thaw stable, remain very low in viscosity and do not phase separate or precipitate for many months. Many of the essential oils found to be useful in this process are non-toxic food additives and have pleasant scents, have low flammability yet are volatile enough to evaporate upon cure down of the SQAC, thereby resulting in a higher concentration of SQAC in the cured, antimicrobial film. Economically shippable concentrations of the stabilized SQACs can be further diluted with water to application concentrations without loosing any of their stabilizing properties and remain storage stable at these lower concentrations indefinitely. In particular, the invention relates to the use of such viscosity controlled aqueous dilutions cured as durable antimicrobial coatings for human or animal skin that covalently bond to the skin, remain active through many washings and reduce or eliminate bacteria, viruses and fungi for days.
Exopolysaccharide for treatment or care of skin, mucous membranes, hair or nails
A method includes administering a cosmetically or dermopharmaceutically effective quantity of exopolysaccharide of a bacterial strain isolated from Pseudoalteromonas sp. with deposit number CNCM I-4150 to at least one of skin, mucous membranes, hair and nails for the treatment and/or care of the skin, mucous membranes, hair and/or nails, and cosmetic and/or dermopharmaceutical compositions including the exopolysaccharide. In particular, the method and composition are suited to treatment of the aging of skin and for the treatment and/or care of disorders, conditions and/or diseases which are a result of a lack or decrease in hydration.
