A method of emulsification of an oil phase in an aqueous continuous phase, by dispersing core-corona microparticles into the aqueous phase, adding the oil phase, and applying shearing force for a time sufficient to emulsify the resulting mixture. The core-corona microparticles are obtained by radical co-polymerization of a polyethylene oxide macromonomer with at least one hydrophobic acrylate monomer and at least one hydrophobic acrylamide monomer.

The present invention provides nanoparticle compositions including one or more peptides. The present invention achieves transdermal delivery of such peptides without the need for peptide modification, or for use of chemical or mechanical abrasion or disruption of skin.

The invention provides a nanoemulsion formulation comprising an aqueous phase, an oil phase dispersed in the aqueous phase, and at least one surfactant. The oil phase includes a cannabis oil. The present invention also provides a preparation that comprises the nanoemulsion formulation. The preparation can be an edible, a beverage, or a pharmaceutical preparation. The present invention still further provides a method of preparing such formulations.

A hair conditioner composition comprising: a) a basic amino acid; b) a fatty acid; c) a high melting point fatty alcohol; and d) an aqueous carrier; wherein a) through d) form a lamellar gel network matrix with a L.sub.β phase.

A hair conditioner composition comprising: a) a fatty acid; b) a fatty alcohol; and c) an antimicrobial system comprising: i) glyceryl caprylate; and ii) one or more of 4-hydroxyacetophenone and pentylene glycol.

Janus particles, including biodegradable, biocompatible, anisotropic, amphiphilic Janus nanocolloids, and their use in stabilizing emulsions and cleansing are described.

Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin.

The present invention relates to novel oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as C.sub.8 to C.sub.18 fatty acid; and the aqueous phase contains specific N-acyl derivatives of amino acid salt as emulsifier.

A dermatological preparation comprises an optimized, modified human embryonic fertility culture media with biguanides and/or functional equivalents and the use of said preparation for skin care, hair care, or body care, or dental procedures, or for regenerative medicine such as promoting wound or bone healing. The preparation is formulated to target the hypoxic microenvironment niches of the skin tissue in combination with optimal concentration of nutrients, ions and minerals; to stimulate existing stem cells to trigger the capacity of stem cells to divide and renew and differentiate into specialized cells; and to stimulate molecular and physiological processes, e.g., autophagy, to replenish the substrate pool through the recycling of organelles and the recycling of old damaged proteins and countering free-radical damage to promote anti-aging.

Rinse-off cleansing compositions can include surfactant, perfume, solvent, and water, wherein the rinse-off cleansing composition has a G′ of at least about 25 Pa and/or is not a ringing gel.
