Compositions for topical application that effectively deliver antioxidants across the epidermis, dermis, or a combination thereof into cells and/or the bloodstream while concurrently maintaining chemical activity of the antioxidants. In certain aspects, these formulations include emulsions and balms each having a lipophilic carrier and a lipophilic antioxidant solubilized by the lipophilic carrier. Also disclosed herein are methods for making these compositions for topical application.

There is described the manufacturing of a support (6) for cosmetic products, which consists of a dry and solidified set of a mixture consisting of non-synthetic ingredients of natural origin only. The support can be manufactured so as to form a base for supporting and anchoring a cosmetic product inside a container (9) or a biodegradable container in the shape of a rigid and self-supporting cosmetic wafer for anhydrous or gel cosmetic products.

Suggested is an antimicrobial mixture comprising or consisting of (a) at least one monocyclic sesquiterpene alcohol, (b) at least one active selected from the group consisting of 4-hydroxyacetophenone, sorbitan caprylate, cocamidopropyl PG-dimonium chloride phosphate, tetrasodium glutamate diacetate, glyceryl caprylate and glyceryl caprate, and optionally (c) at least one additional antimicrobial agent different from components (a) and (b).

A reconstitutable surfactant-based powder has good solubility in water and forms a stable gel when dispersed in water. The reconstitutable surfactant-based powder consists of a polymer/gum system and a dry powder extract.

The present disclosure relates to silica particles comprising repeating units of (SiO.sub.4/2) that are spherical in shape, which has the benefit of compatibility with personal care components and the resulting personal care applications. The present disclosure also relates to methods of preparing silica particles.

A preservation system comprising: i) itaconic acid or salt thereof and ii) a secondary preservation chemical selected from the list consisting of terpineol, geraniol, perillyl alcohol, menthol, terpinene, linalool, citronellol and mixtures thereof.

A modified precipitated silica comprising precipitated silica and at least one polymer selected from the group consisting of poly(ethylene glycol) methyl ether methacrylate and poly(vinylphosphonic acid) is useful for the manufacture of peroxide-based whitening oral care compositions having improved stability over time. It is also useful for the manufacture of elastomeric compositions having a performing balance of properties including e.g. high rolling resistance and/or high wear resistance.

Systems for preserving a cosmetic formulation and for preventing growth or survival of microorganisms on a cosmetic formulation include a cosmetic container and a cosmetic formulation disposed therein and having an argon gas reservoir which is formed within the cosmetic formulation such that rupturing the reservoir releases argon gas onto an adjacent cosmetic-air interface and displaces oxygenated air therefrom. Methods for manufacturing and preserving a cosmetic formulation include preparing a cosmetic formulation that is free of exogenous chemical preservatives but may contain natural preservatives, forming the argon gas reservoir, and sealing a container containing the cosmetic formulation in a nonvacuum, argon gas environment to form an argon gas blanket in the container headspace. The argon gas reservoir can be formed as microbubbles or a chimney of argon gas disposed vertically in the container or as other discrete pockets within the formulation and/or container.

The present invention relates to a composition comprising i) at least one 4-(3-ethoxy-4-hydroxyphenyl)butan-2-one compound; ii) at least one preserving agent other than i) and/or antioxidant; iii) at least one surfactant chosen from the surfactants; iv) at least one polymer, notably a thickening polymer, which is preferably organic, and v) optionally a fatty substance. The invention also relates to the use of i) to vi) as antimicrobial agent, to a process for treating keratin materials using the composition comprising i) to vi) and to a kit comprising ingredients i) to vi).

The combination of i) ii), iii), iv) and optionally v) makes it possible to obtain an antimicrobial mixture which has excellent antimicrobial activity, in particular with respect to Aspergillus niger, Escherichia coli, Staphylococcus aureus and Candida albicans. In addition, the formulations remain stable over time while at the same time retaining antimicrobial activity over time even after 7 days, 15 days, 1 month, and at room temperature.

A hair cleanser is provided, comprising: a dermatologically acceptable vehicle; a dermatologically acceptable hair care cleansing surfactant; a dermatologically acceptable silicone; and a deposition aid polymer, wherein the deposition aid polymer is a dextran polymer crosslinked with a dextran crosslinking agent of formula (I)

##STR00001##

wherein X is a halogen; wherein each R.sup.1 is independently selected from a substituted or unsubstituted C.sub.1-6 alkyl group; wherein each R.sup.2 is independently selected from the group consisting of a C.sub.1-6 alkanediyl group; wherein Y is a divalent bridging group; and wherein the deposition aid polymer enhances deposition of the dermatologically acceptable silicone from the hair cleanser onto mammalian hair.
