  • Patent number: 9345304
    Abstract: It is provided a nozzle (10) for applying a powder, particularly a pulverized hair treatment product, particularly preferred a cosmetic and/or dermatological product, comprising a cap (12) for being connected to a squeezable container for storing the powder, an outlet conduit (14) protruding from the cap (12) along an axial direction (16) for dispensing the powder through the cap (12). According to the invention a mesh (28) covering the outlet conduit (14) for retaining the powder and for pulverizing powder agglomerates is provided, wherein the mesh (28) comprises in a region covering the outlet conduit passages, and the outlet conduit (14) comprises an inner surface (22) for guiding the powder, wherein the inner surface (22) is inclined with respect to the axial direction (16) of the outlet conduit (14) by an angle ? of 0.0°<?<15.0°, particularly 1.0°<?<12.5°, preferably 1.5°<?<8.0°, further preferred 2.0°<?<7.0°, more preferred 2.5°<?<6.0° and most preferred ?=3.0°±0.2°.

  • Publication number: 20120244082
    Abstract: Present invention relates to a hair styling gel foam which boosts exceptionally hair volume. The inventors have surprisingly found out that a composition comprising at least one cationic polymer, at least one silicone oil, at least one thickener and a propellant mixture of alkane and dimethylether in an aqueous or aqueous-alcoholic medium has excellent hair styling and restyling benefits together with excellent volumizing and bodifying effects and also exceptional with the cracking sound heard when foam disappears. The hair feels excellently natural both visually and upon touching and looks excellently shiny.

  • Publication number: 20120244083
    Abstract: Present invention relates to a hair styling emulsion foam which has excellent setting, shine enhancing and volumizing and bodyfiying effects even it is applied in comparatively small quantities. Accordingly, the object of the present invention is an aqueous emulsion foam composition comprising at least one oil and/or a wax or their mixture, at least one emulsifier, at least one adipic acid ester and at least propellant.

  • Publication number: 20060110335
    Abstract: The present invention is related to a sprayable aerosol foam styling composition. The present invention aims at developing a foaming spray styling product with excellent volume up effect and with quick breaking foam, which makes partial application especially at hair root area possible. Furthermore the objective of the present invention is as well to develop sprayable foaming hair styling composition, which does not make hair extremely rough and hard and therefore easy to work out into hair during styling. The inventors have surprisingly found out that an organic solvent free (other than propellants) hair styling composition comprising at least one amphoteric polymer and at least one non-ionic polymer pressurised with a propellant combination of C2-C4 alkanes or halogenated alkanes and dimethylether shows excellent volume up effect.

  • Patent number: 6027718
    Abstract: Organopolysiloxanes composed of an organopolysiloxane segment and a poly(N-acylalkyleneimine) segment which is bonded to at least one silicone atom of said organopolysiloxane segment via an alkylene group containing heteroatom(s) and which consists of repeating units represented by formula (1): ##STR1## wherein R.sup.1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; and n is a number of 2 or 3;wherein the weight ratio of the organopolysiloxane segment (a) to the poly(N-acylalkyleneimine) segment (b) [(a)/(b)] is at least 5/95 and less than 40/60, and the weight-average molecular weight is from 10,000 to 500,000.These organopolysiloxanes are soluble or dispersible in water and can form a film with an excellent texture. Thus, they can be appropriately employed as additives for cosmetic products.
