An ethylene oxide-free, dioxane-free, and formaldehyde-free personal care concentrate composition free of ethoxylated components which is non-irritating to eyes comprising water, sodium alkyl sulfate, propanediol, and a synthetic amphoteric surfactant selected from the group consisting of cocamidopropyl hydroxysultaine and cocamidopropyl betaine is disclosed. This composition is especially suitable for baby shampoos which are not irritating. In some embodiments the composition is free of formaldehyde.

The present invention describes compositions and methods for treating, preventing and improving the appearance of skin, particularly, treating, preventing, ameliorating, reducing and / or eliminating skin irritation, inflammation, and / or the signs of visible or subjective discomfort, wherein the compositions include natural plant constituents that inhibit at least one cytokine. The plant extracts are preferably derived from Populus nigra, Rhinacanthus nasutus, Sapindus rarak, and Thumbergia laurifolia, and any combinations thereof. The compositions are preferably applied to the skin, or are delivered by directed means, to a site in need thereof.

The invention relates to a personal care composition having reduced eye irritation. The present invention is directed to a stable, minimal energy required self-assembling lamellar and spherulite composition comprising: mixture water, fatty alcohol, fatty acid, salt of fatty acid, polyglyceryl fatty acid ester and oils. The present invention relates to composition that can benefit eye mildness, even distribution of sunscreen physical filters on skin and enhanced stability.

Regarding Diquafosol ophthalmic solution comprising a chelating agent at a concentration of 0.0001 to 1% (w / v), formation of insoluble precipitates found in Diquafosol ophthalmic solution during storage of the solution, as well as deterioration of the filtration performance in the course of production (course of filtration sterilization), have been inhibited. Further, in Diquafosol ophthalmic solution comprising a chelating agent, reduction of eye irritation and enhancement of the preservative effectiveness have been confirmed, in comparison to Diquafosol ophthalmic solution comprising no chelating agent. Accordingly, the present invention has been confirmed to provide physicochemical properties that are stable during the courses of production and distribution as well as the course of storage by a patient, and also reduce eye irritation and enhance preservative effectiveness.

The invention discloses a cation-modified pilocarpine hydrochloride flexible nano-liposome eye-drops preparation and a preparation method thereof. The preparation method comprises the following steps:(1) adding lecithin and cholesterol into chloroform, and performing ultrasonic treatment to obtain suspension; and dissolving pilocarpine hydrochloride and a penetration enhancer in methanol to obtain a solution I; (2) uniformly mixing the suspension and the solution I, and removing an organic solvent to obtain a uniform lipid membrane; (3) dissolving a softener into purified water to obtain a solution II, and dissolving the lipid membrane into the solution II so as to obtain primary mixed emulsion; (4) performing ultrasonic treatment on the primary mixed emulsion, and adding into a warm bathso as to obtain a pilocarpine hydrochloride flexible nano-liposome preparation; and (5) dissolving a cationic material into the purified water to obtain a solution III, stirring the pilocarpine hydrochloride flexible nano-liposome preparation, dropping the solution III, and stirring, thereby obtaining the eye-drops preparation in the invention. The preparation disclosed by the invention has hugemembrane surface area and high adhesion, and the drug penetration is increased. The eye-drops preparation has excellent biocompatibility and low eye irritation.
