Bicycloalkane to enhance hair growth

Reference: WIPO Patent Application WO/2015/157771
Publication date: Oct. 15, 2015
Assignee: BCS Business Consulting Services Pte., Ltd., and C Burnison

“This patent application describes compositions for improving the appearance of thinning hair using a lower alkyl-substituted bicycloalkane in combination with minoxidil and, optionally, catalase, hair dye, temporary hair color, Pisum sativum (pea) and/or pseudocatalase.
According to the inventors, the minoxidil and lower alkyl-substituted bicycloalkane increase the growth of hair on the scalp while the latter simultaneously inhibits collagen destruction caused by the minoxidil. Optionally, P. sativum sprout extract may be added to further increase hair growth while catalase increases the natural pigmentation of the subject’s hair, which can lose color due to the minoxidil.
Further, the composition may include a hair dye. Said composition may be delivered as a solid, ointment, oil, lotion, cream, gel, foam, mousse, aerosol, shampoo, hair conditioner and/or liquid. It may be provided in a sustained-release formulation, particularly for once daily application or dosing.”

2-Sensory in Spray Sunscreen

This invention is a sprayable gel sunscreen with good feel properties from Honeywell International.

3Sprayable gel sunscreen composition

Reference: WIPO Patent Application WO/2015/157007
Publication date: Oct. 15, 2015
Assignee: Honeywell International Inc.

“According to the inventors, gels have a relatively high viscosity compared to liquids, and may thus be unsuitable for use in spray sunscreens. Accordingly, a sunscreen dispensed as a finely dispersed spray, while simultaneously having desirable feel properties, is desirable.
In response, disclosed in this patent is a composition that includes a sunscreen active, a volatile, an oil phase solvent and a rheology-modifying ethylene copolymer. The composition is in the form of a thixotropic gel that may be dispersed to the skin using an aerosol- or non-aerosol-based spray apparatus. Methods for preparing the composition also are disclosed.”

3-Non-whitening Photoprotection

This highlight from Eveready Battery Company Inc. is a novel non-whitening, non-irritating composition based on a sunscreen, an aliphatic hydrocarbon and an ester.

Non-irritating, non-whitening photoprotective composition

Reference: WIPO Patent Application WO/2015/152865
Publication date: Oct. 8, 2015
Assignee: Eveready Battery Company, Inc.

« Disclosed in this patent is a photoprotective composition that can be utilized for a variety of cosmetic compositions. The composition includes one or more photoactive agents chosen from p-aminobenzoic acid and derivatives thereof, butyl methoxydibenzoylmethane, benzophenones, octisalate, titanium dioxide and several others (see patent for full listing), at least one aliphatic hydrocarbon and at least one ester.
The resulting composition is substantially non-whitening and non-irritating. It can be anhydrous, single-phase, water-resistant and provide any combination of these characteristics without additional ingredients required. In liquid form, it is easily and consistently dispensed from a bottle, pump or spray.”

4-Translucent Color Cosmetic

This choice, from L’Oréal et al., describes a translucent, colored cosmetic to impart a warm tone on skin.

5
Composition with optical effects

Reference: WIPO Patent Application WO/2015/152421
Publication date: Oct. 8, 2015
Assignee: L’Oréal, R El Akkari and A-L Bernard

“ Disclosed in this patent is a cosmetic composition including: a) at least one oil phase including one or more triglyceride oils; b) at least one polyol including one or more polyols; and c) at least one surfactant phase including one or more nonionic surfactants.
At least one of the phases, i.e., a), b) and c), is visually distinct from the others. Further, the amount of triglyceride oil is at least 7.5 % w/w, preferably 10.0 % w/w or ideally, 15.0 % w/w relative to the total composition.
The composition can be translucent and exhibit a warm color, in particular a shiny warm color, when shaken well by hand and observed through normal white background light. These unique optical effects can draw visual interest from potential consumers.”

5- Odor-free Polymeric Thickener

This feature discloses a novel polymeric thickener free from acrylamide fragments; and therefore, free from odor.

image002Polymeric thickening agent preparation and use

Reference: U.S. Patent 9144610
Publication date: Sept. 29, 2015
Assignee: SEPPIC

« Disclosed in this patent is a composition including an oil phase, an aqueous phase and at least one water-in-oil (w/o) emulsifying system in the form of a positive latex.

The composition includes a straight, branched or cross-linked anionic polyelectrolyte, including:

a) a non-zero molar proportion of monomer units from acrylic acid in free or partially salified form;

and b) a non-zero molar proportion of monomer units from the acid of the formula:
CH2═CH—C(═O)—O—[CH2—CH2—C(═O)—O]n—H
where n is a number greater than or equal to one (1) and less than or equal to five (5), and in free or partially salified form. A method for preparing the composition, a polymer powder and its use as a thickening agent for cosmetics or pharmaceuticals also are described.

According to the inventors, self-invertible inverse latexes exist in the prior art. However, their thickening power is not entirely satisfactory and their unpleasant odor due to the presence of a nitrogen base limits their use in the cosmetics industry. For example, one European patent application discloses copolymers of acrylic acid with acrylic acid dimer, which are used as photographic film layers.

A German patent application also describes copolymers of 2-acrylamido-1-methylpropanesulfonic acid and carboxyethylacrylate, which are used in the cosmetics industry. The present invention is said to provide better thickening without unpleasant odor.”
