The invention described herein includes a self-neutralizing amino acid-based cationic composition that contains an amino acid-based cationic ester, a nonionic amphiphile, and an anhydrous buffering agent. In an embodiment, the composition, when dispersed or dissolved in an aqueous solvent, provides a resultant solution/dispersion having a pH of greater than about 4. The amino acid-based cationic ester may be a reaction product of (i) an amino acid having a non-polar side chain, and an amine group that has been neutralized with an acid; with (ii) a long chain fatty alcohol. Also included within the scope of the invention are methods of preparing a self-neutralizing amino acid-based cationic composition, such method including combining an amino acid-based cationic ester, a nonionic amphiphile and an anhydrous buffering agent. The resulting composition is in an anhydrous solid form. Formulations containing the amino acid-based cationic ester and/or a composition that includes it, are also disclosed.

The invention relates to a cosmetic process for treating keratin fibers, preferably the hair, comprising at least the steps consisting in: a) applying to said keratin fibers a composition containing at least one substance chosen from fatty substances, non-silicone polymers and surfactants, b) applying a mechanical tension to said keratin fibers, and c) exposing said keratin fibers under mechanical tension to microwaves, at a pressure ranging from 50,000 to 250,000 Pa, in the presence of at least one solvent in vapor form on contact with the keratin fibers and without there being complete drying of the keratin fibers throughout the entire exposure to the microwaves, the solvent(s) in vapor form being entirely generated by evaporating at least one compound present, before emission of the microwaves, on contact with the keratin fibers, step a) taking place prior to step c).

Embodiments described herein relate generally to apparatus, methods and systems for low energy processing of consumer personal hygiene products (PHPs) and formulations of the same. In some embodiments, a method of manufacturing a consumer PHP comprises combining a first material and second material at room temperature to form a first mixture, mixing the first mixture at room temperature, adding a third material at room temperature to form a second mixture; mixing the second mixture at room temperature, adding a fourth material at room temperature to form a third mixture; and mixing the third mixture at room temperature. In some embodiments, the third material and the fourth material can be mixed to form the second mixture and the first mixture and second mixture can be combined to form the third mixture. In some embodiments, the mixing can be accomplished using a propeller mixer. In some embodiments, the propeller mixer can be rotated at a speed of greater than about 200 rpm during at least one of the mixing steps. In some embodiments, the pH of the third mixture can be adjusted to between about 4.5 and about 6.5 using an acidifier. In some embodiments, the viscosity of the third mixture can be adjusted to between about 100 cP and about 25,000 cP using a thickener.

Disclosed is a composition in the form of an oil-in-water emulsion and including: a) at least one oil; b) at least one cross-linked anionic polyelectrolyte; c) at least one water-in-oil emulsifying surfactant including an alkylpolyxyloside having a non-linear branched alkyl radical and having 10 to 36 carbon atoms; d) at least one oil-in-water emulsifying surfactant; e) at least one hydrophobic perfuming substance; and f) water.

The invention relates to a cosmetic process for treating keratin fibres, in particular human keratin fibres such as the hair, using at least one particular metal compound belonging to the group of the rare-earth metals and at least one fixing polymer.

The invention provides a liquid cosmetic that contains capsule in an aqueous medium, wherein the capsule comprises agar shell encapsulating an oil component, and the aqueous medium comprises a low molecular polyol and one selected from the group consisting of a (meth)acrylic polymer and a polysaccharide.

Disclosed is a method for using a two-step cosmetic product, such as used on the lips, that includes the use of a basecoat that utilizes a surface-stabilized dispersion of copolymer particles and a styrenic block copolymer, and a top coat that utilizes a silicone amine and a viscous silicone, and where the composition(s) are configured to allow the silicone amine to react with the maleic anhydride after the top coat is applied.

The present disclosure relates to fragrance materials encapsulated within polymeric materials in the form of microcapsules of polymer encapsulated fragrance. The microcapsules are mixed with a water-based binding agent so that a coating forms on the microcapsule in situ, after which the coated microcapsules may be applied to hard surfaces of a product, from which controlled release of the fragrance is provided over time as the product is subjected to normal handling by a user.
