Described herein are oral care compositions comprising: from about 35 wt. % to about 85 wt. % of an anhydrous solvent system (e.g., 35 wt. % to about 75 wt. %); from about 0.02 wt. % to about 30 wt. % of a peroxide solution comprising: from about 0.01 wt. % to about 15 wt. % of hydrogen peroxide, and from about 0.01 wt. % to about 15 wt. % of water; from about 1 wt. % to about 20 wt. % of a thickening system; wherein the oral care composition has a total water content of less than about 30 wt. %; and wherein all weight percentages are based on the total weight of the oral care composition. Methods of making and using these compositions are also described herein.

Disclosed herein are oral care compositions that may include, in certain aspects, from about 40 wt. % to about 75 wt. % of a humectant; from about 5 wt. % to about 25 wt. % of an abrasive system; from about 0.3 wt. % to about 1 wt. % of a thickening system; and particles having a refractive index of from about 1.0 to about 2.5; wherein the composition is substantially free of a titanium containing material. Methods of making and using the oral care compositions are also provided.

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.

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.

Disclosed is a self-invertible inverse latex including, as an inverting agent, surfactant species of the polyglycerol ester family; the use thereof as a thickening and/or emulsifying and/or stabilising agent for a cosmetic, dermopharmaceutical or pharmaceutical topical composition, and cosmetic, dermopharmaceutical or pharmaceutical topical compositions containing same. Also disclosed is a new surfactant composition containing polyglycerol esters.

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.

Hair care compositions and methods for providing conditioning benefits to hair is disclosed. The hair care compositions may include one or more nonionic surfactants comprising one or more alkylpolyglucosides; one or more fatty alcohols; one or more fatty esters comprising caprylic/capric triglyceride; about 0.5 to about 30 wt. % of a fatty compound other than fatty alcohol and fatty ester; one or more silicones comprising polysilicone-11; one or more thickening agents; and water, wherein the hair care composition is an emulsion, and all weight percentages are based on the total weight of the hair care composition.

Personal care products, such as shampoos, conditioners, hair dyes, hair removal products, cleansers, cosmetics, mascaras, and toothpastes may be formulated to include one or more surfactants, from one or more surfactant classes, such as siloxane derivatives of amino acids that have surface-active properties.

The invention relates to a method for the cosmetic treatment of keratin materials, in particular human keratin materials, such as the skin or hair, comprising a stage of application of a composition comprising a compound of a metal belonging to the group of the rare earth metals, followed by a stage of application of an alkaline composition.

The instant disclosure relates to cosmetic compositions that when applied to skin instantaneously and dramatically improve the appearance of the skin. The compositions include volatile hydrocarbon oil; mineral thickening agents; silicone elastomers; and hydrophobic film forming polymers; wherein the weight ratio of the total amount of hydrophobic film forming polymers to the total amount of mineral thickeners (film forming polymers: mineral thickening agent) is 1:1 to 8:1, and the weight ratio of the total amount of silicone elastomer to the total amount of mineral thickener (silicone elastomer: mineral thickening agent) is 1:1 to 5:1. Methods for improving the appearance of skin comprising application of the cosmetic compositions to the skin are also disclosed.
