The invention pertains to a drier composition for air-drying alkyd-based coatings, inks, or floor coverings, comprising a combination of the following components: a) a transition metal salt with the formula: (Men+)(Xk−)m in which Me is the transition metal; X− represents a coordinating ligand; and k− is the valence state of the transition metal and m is the number of ligands X. b) a reducing biomolecule. The reducing biomolecule is in particular ascorbic acid or a derivative thereof, including ascorbyl palmitate.

The invention belongs to the technical field of daily chemical products, and specifically relates to a whitening and freckle-removing essence; the whitening and freckle-removing essence comprises the following constituents: constituent A, including humectant, thicken stabilizer, emulsifier, anti-allergy remediator and water; constituent B, including thickener, emulsifier, emollient, ascorbyl palmitate, tocopherol, antioxidant, and preservative; constituent C, including emollient, polydimethylsiloxane cross-linked polymer, and thicken stabilizer; constituent D, including 4-butylresorcinol, extractant of aloe vera, extractant of roots of polygonum cuspidatum, and pH regulator; and constituent E, including tranexamic acid, water, preservative and essence. Comparing with the prior art, the whitening and freckle-removing essence can not only infiltrate to the basal layer of skin, but also can effectively inhibit the activity of tyrosinase, effectively remove oxygen radical, prevent the generation of melanin, reductively decompose the existing melanin as well, activate cells, and fade facial spots, thus achieving the effect of comprehensively and quickly resolving the current problems and eliminating the root causes, making the skin white, moist, and exquisite.

The invention relates to a preparation method of L-ascorbyl palmitate, which includes directly conducting esterification reaction on L- ascorbic acid and palmitic acid under the existence of concentrated sulfuric acid, adding an ice water mixture after reaction, conducting extraction through an organic solvent, conducting reduced pressure distillation on extraction liquid to obtain a coarse product, and conducting recrystallization on the coarse product through a mixed solvent of petroleum ether and ethanol to obtain the L-ascorbyl palmitate. The technical scheme of the preparation method improves quality and purity of the L-ascorbyl palmitate, and the product is good in appearance, stable in quality and capable of achieving national food grade standard. Further, the whole process is mild in reaction condition, convenient to operate and wide in reagent source. The preparation method of the food grade L-ascorbyl palmitate is ideal and effective.

The disclosure also describes a method for creating a composition, comprising: a) preparing a water phase mixture with a base of deionized water; b) optionally adding thickening or thinning agents into a water phase and mixing until free from lumps; c) optionally adding carrageenan into the mixture and mixing until free of lumps; d) heating the mixture to up to 80° C.; e) adding vegetable glycerin and optionally aloe vera gel or liquid and mixing until completely uniform; f) preparing an oil phase mixture by heating one or more carrier oils to up to 75° C.; g) adding a dispersant, SPF boosting oils and / or waxes, and optionally stearic acid, an anti-oxidant, and vitamin E oil, and mixing until all the solids are dissolved; h) slowly adding sucrose stearate, maintaining temperature; i) adding inorganic sun-block agents while homogenizing until smooth and uniform; j) increasing the temperature to up to 80° C. and adding said water phase mixture; k) mixing until smooth and homogenous; l) cooling the mixture down to 45° C. or less; m) adding aloe vera gel, and optionally a salt, grapefruit seed extract, and ascorbyl palmitate, powdered butter milk, and powdered milk; n) adding preservatives; o) adding essential oils; and finally p) mixing until smooth and homogenous. The compositions of the present disclosure are shown to be capable of protecting skin and mammalian health from the harmful effects of radiation including ultraviolet light or sunlight by inhibiting the loss of skin immunocompetency and eliminating any known or suspected endocrine disrupting agents normally utilized as sun protective agents.

The invention relates to a dermatological pharmaceutical composition for the treatment of skin inflammation diseases, such as dermatitis, atopic dermatitis, vitiligo, alopecia areata, acne, psoriasis and pruritus. The invention comprises a basic anti-inflammatory agent, such as indometacin; one or more optional active principles selected alternatively from among at least a corticoid and an antibiotic; and a combination of topical antioxidants used to potentiate the anti-inflammatory effect, selected from among green tea, lipoic acid, curcumin, ascorbyl palmitate, Coenzyme Q10, resveratrol, Pycnogenol TM , L-camosine, taurine, vitamin E, vitamin C, papaya extract, isoflavones, manganese, lycopene and quercetin. At least one of the topical antioxidants is a peroxisome proliferator-activated receptor-gamma (PPAR- gamma) activator. The invention also includes at least one antioxidant substance with an antiproliferative effect on keratonocytes, e.g. manganese, and at least one substance that blocks tumour necrosis factor-alpha (TNF- alpha) or other cytokines that provoke the acute phase of the inflammatory reaction, also with an antiproliferative effect, e.g. pentoxifylline.
