A topical therapeutic hydrophobic breakable composition includes a carrier comprising, (a) about 60% to about 99% by weight of at least one hydrophobic oil; (b) at least one viscosity-modifying agents selected from the group consisting of a fatty alcohol, a fatty acid and a wax; and (c) a tetracycline antibiotic, characterized in that at least part of the tetracycline antibiotic is suspended in the composition; the viscosity of the composition is at least about 30% higher than the viscosity of the carrier without the tetracycline antibiotic; and is higher than the viscosity of the hydrophobic oil and the tetracycline antibiotic without the viscosity modifying agents. The tetracycline is chemically stable in the composition for at least six months; wherein more than about 90% of the tetracycline has not broken down. The composition is packaged as a breakable foam that breaks easily upon application of shear force.

A computer-based method for determining a sunscreen composition comprising a plurality of UV filter substances, comprises the steps of selecting at least one constraint for at least one characteristic of the composition to be determined (step 30), the at least one constraint comprising a sunscreen performance target; selecting an optimization objective from a plurality of optimization objectives (step 50); and automatically determining the sunscreen composition as a composition of filter substances from a set of filter substances (step 100), the composition meeting the at least one constraint and being optimized with respect to the selected optimization objective. The automatic determination comprises the steps of generating a plurality of candidate compositions, determining a sunscreen performance of the candidate compositions using a performance simulation tool and comparing the determined sunscreen performance of the candidate compositions with the sunscreen performance target. The method allows for an automatic determination of an optimum sunscreen composition based on constraints and objectives, thus avoiding manual trial and error methods that are lengthy and do not always lead to the optimal result.

An oral care composition containing a gel phase, an abrasive, and a fluoride source. The gel network phase contains a fatty amphiphile and phase separation is not visually perceptible in the oral care composition.

Acidic oral compositions having calcium contents and effective pH-values in the area indicated by grey-tone in FIG. 2 are non-erosive in saliva and capable of stimulating saliva production, even in dry mouth patients. A new multi-step test method for determining erosive potential in saliva has been used for identifying the compositions.

A nail compositions comprising at least one photo-curable polymer dispersed in water (latex), at least one polyurethane non-photo-curable polymer dispersed in water (latex), at least one photo-initiator, optionally at least one plasticizer, optionally a colorant, and water are provided. Also provided are nail composition systems and kits comprising the nail compositions of the invention together with a base coat composition and/or a top coat composition.

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).

This invention relates to a skin-penetrating skin-care product, which is made of natural, raw ingredients including, among other things, plants, algae and fungi. Skin-care products are generally composed of highly processed components and they often comprise only few isolated nutrients. This invention intends to solve the problem of lack of quality and quantity of nutrients in the skin-care products.

In certain embodiments, the present invention relates to compounds, compositions, and methods for disrupting biofilms. In some embodiments, the compounds and compositions comprise unsaturated long chain alcohols and/or aldehydes, or combinations of such compounds. In further embodiments, the present invention contains therapeutic actives to help reduce and/or eradicate the bacteria in the biofilm once the film is disrupted.

A micro electromechanical ink jet printing system that has a cartridge having a body that defines a core, and a die that contains one or more nozzles. There is a treatment composition contained within the cartridge core. The system further includes a CPU that is programmable and can control the application of the treatment composition from within the cartridge core, through the one or more nozzles to human skin. Typically, the treatment composition will contain a skin treatment ingredient selected from the group consisting of particles, vitamins, yeast and yeast extracts, skin care actives, dyes, colorants and mixtures thereof. There may optionally be provided a bladder or foam block disposed within the cartridge core for suspending and regulating the flow of the treatment composition. The systems of this invention may include an applicator having an applicator head having one or more applicator nozzles which may be in a array. The applicator has a sensor that takes an image of at least 10 m.sup.2 of skin, the CPU analyzes the image to calculate one or more localized L values of individual pixels or group of pixels of the skin. Then the CPU compares the local L value to a predetermined background L value to identify skin deviations. A skin deviation occurs where the difference between the background L value and the local L value is greater than a predetermined L.sub.S value.
