The present invention relates to personal care compositions comprising malodor reduction compositions and methods of making and using such personal care compositions. Such personal care compositions comprising the malodor control technologies disclosed herein provide malodor control without leaving an undesireable scent and when perfume is used to scent such compositions, such scent is not unduely altered by the malodor control technology.

The invention relates to compounds of general formula (I), ##STR00001##
in which each E independently represents O or NR.sup.1, with the proviso that at least 1 E is not O and at least 1 R.sup.1 represents a substituted C.sub.1-22 alkyl of the general formula (IIa) or (IIb) or (IIIa) or (IIIb), ##STR00002##
in which Q represents O or CH.sub.2, w represents a number from 1 to 22, q represents 1 or 2 and A.sup.+ represents a cation selected from alkali metal cations where q=1, ½ alkaline earth cations where q=2 and ammonium ions where q=1, as well as metal complexes having this ligand compound and dishwashing detergents which contain such metal complexes.

The invention relates to surfactants of general formula (I) in which R.sup.1 and R.sup.2 represent independently of one another represent H and SO.sub.3.sup.−X+ with the proviso that at least one of R.sup.1 and R.sup.2 is not H, n and m represent independently from each other numbers from 0-21 under the proviso that 4<n+m<26, and X.sup.+ represents a charge-balancing anion. The surfactants can be incorporated into detergents or cleaning agents, have excellent technological application properties and can be produced based on renewable raw materials.

A laundry care composition comprises a laundry care ingredient or adjunct and at least one compound that is capable of changing from a first color state (i.e., the initial color state in the composition) to a second color state that is perceptibly different from the first color state. A method for treating textile articles comprises the steps of: (a) providing a laundry care composition as described above; (b) adding the laundry care composition to a liquid medium; and (c) placing the textile articles in the liquid medium.

The present invention refers to a composition for cleaning application comprising a surfactant and a ketal of formula (I) wherein R1 and R2, independently from one another, are selected in the group consisting of: a linear or branched C1-C12 alkyl, a C4-C12 cycloalkyl or an aryl. R3 is H, a linear or branched alkyl, a cycloalkyl or a —C(═O)R4 group, with R4 being a linear or branched C1-C4 alkyl or a C5-C6 cycloalkyl; and wherein the mass ratio between the surfactant and the ketal is between 80:20 to 20:80. The combination of the specific bio-sourced ketal and surfactant provides a synergic effect, improving the performance of the cleaning product.

A non-oxidizing, buffered disinfectant concentrate is provided to be included in a solution used to disinfect a membrane. The solution applied to the membrane is configured to have a pH that is compatible with the membrane. The disinfectant concentrate includes an aqueous solvent; a hydrotrope; a strong acid surface cleanser; a biocidal active, preferably, at least two biocidal actives; a buffer agent; and, optionally, an anionic surfactant. The biodical active may be selected to function both as a biocide and as a weak acid/buffer combination. A disinfectant solution applied to the membrane includes from about 0.1 wt % to about 3.5 wt % of this disinfectant concentrate.

Fabric treatment compositions that include a treatment adjunct material and certain phenol antioxidants. Process of treating fabrics that include at least one source of malodor by contacting the fabric with such fabric treatment compositions. Premix compositions that include certain phenol antioxidants, and methods of making treatment compositions that include such premixes.

An absorbent substrate such as a wool dryer ball is imbued with a fragrance or treatment composition. The fragrance or treatment composition comprises an aqueous carrier, free fragrance, and encapsulated fragrance. The composition includes about 0.1 wt. % to about 5 wt. % free fragrance and about 0.1 wt. % to about 10 wt. % encapsulated fragrance. A kit includes absorbent balls, the fragrance or treatment composition, and an applicator for applying the fragrance or treatment composition onto or within the absorbent balls.

The present invention relates primarily to fragrance substance mixtures, preferably perfume oils, comprising or consisting of (a) 8,8-dimethyl-6,10-dioxaspiro[4,5]decane, i.e. a compound of formula (I) as described herein, and additionally (b) one or more fragrance substance(s) selected from the group consisting of esters, lactones, oximes and sulphur compounds with a molar mass of 240 g/mol or less and/or (c) one or more fragrance substance(s) selected from the group consisting of acetals, ketones and ethers with a molar mass in the range of 126-240 g/mol. The invention further relates to methods for the production of fragrance substance mixtures according to the invention, methods for enhancing the natural freshness and/or radiance and/or for masking or reducing sulphurous, artificial and/or metallic notes of one or more fragrance substances different from the compound of formula (I), perfumed products containing a fragrance substance mixture according to the invention, methods for producing perfumed products according to the invention and the use of the compound of formula (I) for enhancing the natural freshness and/or radiance and/or for masking and/or reducing sulphurous, artificial and/or metallic notes of one or more fragrance substances different from the compound of formula (I).

The present disclosure provides a laundry care composition having at least one laundry care ingredient and at least one leuco composition conforming to Formula (I):
Ar.sup.1Ar.sup.2Ar.sup.3CH  (I)
wherein Ar.sup.2 and Ar.sup.3 are independently a carbocyclic aryl or heteroaryl, and Ar.sup.1 is selected from the group consisting of: unsubstituted phenyl, electron deficient carbocyclic aryl, and heteroaryl. The present disclosure also provides a method of determining an authentic laundry care composition and test kits for detecting authentic laundry care compositions.
