The present invention relates to novel cosmetic emulsions, comprising 1,2-decanediol, advantageous uses thereof and methods for their production.

Antiperspirant and/or deodorant compositions and methods for the same are provided. The compositions may include an antiperspirant active or a deodorant active, water, and a preservative system. The antiperspirant active may include aluminum, and the preservative system may include a biodegradable amino carboxylate. The methods may include substituting or replacing a conventional chelant, such as EDTA, with a biodegradable chelant, such as HIDS. The methods may also include applying one of the compositions to an axillary area of a person.

A method for producing a coating on skin, the method comprising: A) a step of electrostatically spraying a composition X comprising the following component (a) and the following component (b) directly on the skin to thereby form a coating on a skin surface: (a) one or more volatile substances selected from the group consisting of water, an alcohol, and a ketone, and (b) a polymer having a coating forming ability; and B) a step of applying a composition Y, other than the composition X, containing the following component (c) and the following component (d) to the skin: (c) 5% by mass or more and 20% by mass or less of an adhesive polymer, and (d) 1% by mass or more and 40% by mass or less of a polyol, in this order or in reverse order.

Disclosed is a composite for forming a coacervate interfacial film. The composite for forming the coacervate interfacial film contains a cationic hectorite nanoplate-shaped particle structure containing a hectorite nanoplate-shaped particle and a cationic surfactant coupled to a surface of the hectorite nanoplate-shaped particle, and an anionic cellulose nanofibril containing an anionic functional group in at least a portion thereof, in which the composite may form the coacervate interfacial film at an interface of an oil phase and a water phase through electrostatic interaction between the cationic surfactant and the anionic functional group.

An oil-in-water composition is provided. The composition includes an oil-in-water wherein the emulsion includes a) one or more antioxidants, b) one or more SPF boosters, c) one or more acrylate-based polymer capable of stabilizing the composition, d) one or more organic UV filters, e) one or more thickeners, f) one or more film formers; and g) one or more emulsifiers. The oil-in-water composition is provided in which the composition is essentially free of oxybenzone.

Disclosed is a method of improving the penetration of a vitamin B.sub.3 compound into skin. The method involves a skin care regimen in which at least two skin care compositions are used in sequence to treat a target portion of skin where a skin health or appearance benefit is desired. The first composition applied to the skin is a low-pH skin care composition that contains a first concentration of a vitamin B.sub.3 compound. The second skin care composition applied to the skin is a conventional skin care composition that contains a higher concentration of the vitamin B.sub.3 compound than the first composition. When applied in the proper sequence, the regimen results in an unexpectedly high vitamin B.sub.3 flux into the skin.
