Nanoemulsions as emulsion additives are prepared to stabilize actives and prevent formulation discoloration. The nanoemulsions have at least 30% by weight oil and are suitable to add to emulsions and/or structured water to produce color stable end use skin benefit compositions.

Color stable skin benefit compositions

The present invention relates to novel oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as Cto Cfatty acid; and the aqueous phase contains specific N-acyl derivatives of amino acid salt as emulsifier.

Nanoemulsions comprising fatty acid and n-acyl derivatives of amino acid salt

Nanoemulsions and a method for making the same are described. The nanoemulsions comprise a skin benefit agent in the water phase and they are made from two macroemulsions that have non-identical pH values.

Nanoemulsions and a method for making the same

The invention relates to oil-in-water emulsion in which specific oils (e.g., lauric oils) are used in the oil phase while surprisingly maintaining excellent transparency. In one aspect, said emulsions comprise fatty acid in oil phase. The invention comprises an energy efficient process for making said fatty acid containing transparent nanoemulsions.

Process for making transparent nanoemulsions comprising lauric oil

The invention relates to oil-in-water emulsion in which specific oils (e.g., lauric oils) are used in the oil phase while surprisingly maintaining excellent transparency. In one aspect, said emulsions comprise fatty acid in oil phase. In a separate co-pending application, the invention comprises an energy efficient process for making said fatty acid containing transparent nanoemulsions.

The present invention relates to novel oil-in-water pumpable nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as Cto Cfatty acid; and the aqueous phase contains sulfoalkyl ester and/or amide of fatty acids as emulsifier.

The method for making a nanoemulsion is described. The method uses a neutralized fatty acid and does not require traditional surfactant in order to yield stable nanoemulsion having a diameter from 70 to 550 nm.

Nanoemulsions with neutralized fatty acid and a method producing the same

The present invention relates to novel oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum as well as C8 to C18 fatty acid; and the aqueous phase contains specific N-acyl derivatives having specific counterions of amino acid salt as emulsifier, glycerol, and water. When (i) there is defined ratio of glycerol to water; (ii) specific counterion for amino acid surfactant and (iii) fatty acid in oil phase. Nanoemulsions are processed in a one-step process yielding droplets of size 20 to 400 nm. In one embodiment, droplets of size 20 to 400 nm can be made using rotor-stator device (in one-step process) and in the absence of pressure based homogenizer. This saves in energy and cost. Compositions prepared according to this processes are also contemplated.

Nanoemulsions comprising glycerol in aqueous phase

The present invention relates to novel process for making oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum and a Cto Cfatty acid just be added during preparation; and the aqueous phase contains specific N-acyl derivatives of carboxylic amino acid as primary emulsifier.

Process for producing small droplet emulsions at low pressure

A water-in-oil personal care emulsion with water droplets size below 20 microns, the droplets containing solubilized cystine. A process of making an emulsion is also described.

Personal care compositions comprising poorly soluble compounds

Compositions for coloring skin are described. The compositions comprise beads that comprise petrolatum and optionally a colorant and the beads have a diameter from about 90 to about 625 microns. When applied topically, the compositions unexpectedly yield long lasting color.

Composition for coloring skin and method for coloring skin

The invention relates to process for making highly concentrated, spherical biopolymer gel particle suspensions comprising particles of defined particle diameter (e.g., range of 1 to 50&#x3bc;) utilizing high internal phase emulsion as an intermediate.

HIPE-gelation process for making highly concentrated, spherical biopolymer gel particle suspensions

The present invention relates to process for producing bars comprising 20 to 70% by wt. acyl isethionate and 15% to 35% free fatty acid and which is made by process where excess fatty acids made during production of acyl isethionate is removed by neutralization rather than by 'stripping'. The bar retains remarkably desirable consumer properties.
