Ingredient preventing viscosity problems encountered in a perfumed concentrated fabric softener comprising at least an ester of the general formula ,wherein R is a radical of a monohydric aliphatic alcohol or a group (CH 2 ) n COOR 1 or a group CH 2 -CH(OCOR 4 )-CH 2 (OCOR 5 ) and Y is R' which is a saturated or unsaturated straight or branched C 6 -C 24 alkyl group, a group (CH 2 ) n COOR 1 or a group CH 2 -C(OH) (COOR 2 )-CH 2 (COOR 3 ), wherein n is 1 to 6, and R1 - R5 are each a radical of a monohydric aliphatic alcohol.
摘要:
The compounds of the formula I are precursors for organoleptic and antimicrobial compounds. The latter are generated in the presence of skin bacteria, enzymes or acidic or alkaline conditions. One precursor molecule can provide one or more different compounds.
摘要:
The invention relates to organosiloxane fragrance precursor compounds having at least one organosiloxane unit of the formula or a mixture thereof and if any other siloxane unit(s) in the said organosiloxanes being present this/these is/are of formula wherein R represents a substituted or unsubstituted C 1-8 alkyl group or a substituted or unsubstituted aryl group, R represents a hydrogen atom, a monovalent C 1-8 hydrocarbon group or a monovalent C 1-8 halogenated hydrocarbon group; R 1 represents a hydrogen atom or a substituted or unsubstituted C 1-8 alkyl group or a substituted or unsubstituted aryl group or a bond connecting CR 1 and CR 3 ; R 3 represents a hydrogen atom or a substituted or unsubstituted C 1-8 alkyl group or a substituted or unsubstituted aryl group; A represents (CR 4 2 ) n whereby R 4 represents a substituted or unsubstituted C 1-8 alkyl group or a substituted or unsubstituted aryl group or a hydrogen atom and whereby n has a value of 0-20 and each R 4 is the same or different; OR 2 represents the residue of an olfactive alcohol or of the enol form of an olfactive aldehyde or olfactive ketone; a has a value of 0,1 or 2; b has a value of 0, 1, 2 or 3, the use of at least one of the compounds as a fragrance precursor in a cosmetic composition or cosmetic product, laundry product, detergent or fabric softener and to a cosmetic product, a laundry product, a detergent or a fabric softener containing at least one of the compounds.
摘要:
Enzymatic cross-linking of protein-encapsulated oil particles by complex coacervation. A complex coacervate of oil particles, each encapsulated in a protein shell, is stabilized by gelling the protein shell and is subsequently enzymatically cross-linked to form thermostable capsules of about 100-300 microns. The preferred enzyme is transglutaminase, and the reaction is performed at pH 7 to achieve the optimal cross-linking rate. The transglutaminase-catalyzed cross-linking reaction takes place with the complex coacervate maintained at a temperature in the range of about 5°C-10°C to maintain the structural stability of the complex coacervate.
摘要:
The invention relates to agents preventing (the formation of) human malodour. In particular, the invention relates to the use of several classes of compounds which can act as such agents in cosmetic products, such as deodorants and antiperspirants. These compounds are normally odourless or nearly so, but upon contacting the skin as for example, in skin care compositions or in personal care compositions, they prevent malodour. The compounds under consideration are compounds of the formula X-(Z) n -CO-NH-CH-(COO-Y)-CH 2 CH 2 CONH 2 I The definition of the substituents is given in the specification.
