Provided is a method capable of yielding high-purity 1,3-butylene glycol having a very low content of a low boiling point component and a high initial boiling point, with a high recovery ratio. A reaction crude liquid containing 1,3-butylene glycol is subjected to product distillation to yield purified 1,3-butylene glycol, through dehydration including removing water by distillation and performing high boiling point component removal including removing a high boiling point component by distillation. A method for producing 1,3 butylene glycol, the method including: distilling a charged liquid having a water content of 1.2 wt.% or less in a product column for use in the product distillation under a condition of a reflux ratio of greater than 0.1; distilling off a liquid in which a low boiling point component is concentrated from above a charging plate; and extracting 1,3-butylene glycol from below the charging plate.

Disclosed is a method of improving a condition or appearance of skin. The method can include applying to skin an effective amount of a topical skin composition comprising tetrahexyldecyl ascorbate, Phyllanthus emblica fruit extract, and tocopherol or tocopherol acetate.

The invention relates to an extract of flowers, preferably calyxes, from kapok trees, in particular Bombax costatum, to a process for preparing same and to the extract obtainable by said process. The invention also relates to a composition comprising such an extract, the composition being advantageously a cosmetic, pharmaceutical or dermatological composition. The invention also relates to such a composition or such an extract for use in preventing or treating disorders or diseases of the skin, the mucous membranes or keratinous appendages and for use in preventing or treating vascular disorders. The invention finally relates to a cosmetic care process for the skin, the keratinous appendages or the mucous membranes, with a view to improving the condition thereof or the appearance thereof, which process consists in administering such a composition or such an extract.

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.

The present invention provides compositions and methods for wound debridement and healing. The debridement compositions preferably comprise a metalloprotease enzyme such as a choriolytic enzyme.

A high-purity 1,3-butylene glycol product that is colorless and odorless (or almost colorless and odorless), unlikely to cause coloration and odor over time, and/or unlikely to cause an acid concentration increase over time when the product is left in a state containing water is provided. A 1,3-butylene glycol product containing 1,3-butylene glycol, wherein, after the 1,3-butylene glycol product has been kept at 180° C. for 3 hours in air atmosphere, at least one of contents of compounds represented by the following Formula (A) or (B) is less than 8 ppm. In the following formula, R.sup.1 to R.sup.4 are the same as or different from each other, and each of R.sup.1 to R.sup.4 is a hydrogen atom, an alkyl group which has from 1 to 4 carbon atoms and may be substituted with a hydroxy group, or an alkenyl group which has from 2 to 4 carbon atoms and may be substituted with a hydroxy group.

A mild cleansing composition nearly saturated, saturated, or supersaturated with at least one active ingredient includes one or more surfactants and one or more active ingredients. The mild cleansing composition can be used to clean the skin and improve skin texture (e.g., the degree of radiance and wrinkles) at the same time.

The present disclosure describes methods and compositions for inhibiting fungal growth in food and cosmetic products, as well as food and cosmetic products treated with anti-fungal compositions.

A method for treating skin of a person is disclosed. The method can include topically applying to the skin of the person a composition comprising an effective amount of an aqueous, alcoholic, or aqueous-alcoholic extract from Vinca major, wherein the composition reduces melanin production in the skin, increases antioxidant activity in the skin, and/or increases skin moisture content.

Provided is a cosmetic composition for protection of the skin against reactive oxygen species, ultraviolet rays, or blue light, which includes an amide-based compound. The cosmetic composition according to the present invention can effectively inhibit cell damage caused by the reactive oxygen species, the ultraviolet rays, or the blue light and protect the skin without irritating the skin, and can simultaneously aid in recovering the damaged skin.
