Definitions
- This invention relates to laundry rinses and dryer sheets containing N,N-dihydrogenatedtallow-N,N-dimethylammonium chloride and an amine oxide.
- a fabric softener that is commonly used is N,N-dihydrogenatedtallow-N,N-dimethylammonium chloride (DTMAC), which is both inexpensive and effective as a softener but, on the other hand, has certain deficiencies, such as its yellowing and reducing the washability of the softened fabrics, having inefficient antistatic activity on polyesters, and decreasing the rewettability of the treated fabrics.
- DTMAC N,N-dihydrogenatedtallow-N,N-dimethylammonium chloride
- Amine oxides such as N-alkyl-N,N-dimethylamine oxides, are also effective fabric softeners; and they sometimes have advantages over DTMAC in this regard. However, when used together with DTMAC, they have either failed to improve the results obtained with DTMAC alone or have provided results intermediate to those obtained with either component of the fabric softener alone.
- US-A-3 843 395 addresses the improvement of fabric softening compositions with respect to staining of laundry.
- the softening composition is impregnated into an absorbent material.
- the softening compounds may be chosen from a broad range of compounds including 9 general formulae and thus 9 different classes of compounds which may be used alone or in combinations thereof.
- an N-octadecyl-N,N-dimethylamine oxide together with N,N-dihydrogenatedtallow-N,N-dimethylammmonium chloride can provide an improved fabric softener product when the fabric softener product is (1) a laundry rinse which comprises as the sole fabric softener an aqueous solution of a mixture of 25-80% of the by weight of the quaternary ammonium chloride and 75-20% by weight of the amine oxide or (2) a laundry dryer sheet which comprises a flexible absorbent substrate impregnated with a fabric softener that is a mixture of 10-80% by weight of the quaternary ammonium chloride and 90-20% by weight of the amine oxide.
- the quaternary ammonium chloride component of the fabric softener mixture is the known N,N-dihydrogenatedtallow-N,N-dimethylammonium chloride (DTMAC).
- DTMAC N,N-dihydrogenatedtallow-N,N-dimethylammonium chloride
- the DTMAC used in preparing the mixture is generally the material that is most commonly available, i.e., a 75% paste in an alcohol.
- the amine oxide component of the mixture is N-octadecyl-N,N-dimethylamine oxide.
- the amine oxide used in preparing any of the products of the invention may be a conventional aqueous solution or a solid amine oxide, such as the amine oxide dihydrates described in European Patent Application 0401503 and British Patent Application 2,240,791, it is apt to be preferred to employ an amine oxide in solution form when the mixture is to be utilized as an aqueous solution and otherwise to employ a solid amine oxide.
- a laundry rinse of the invention is a conventional rinse which has water as its major ingredient (generally comprising 70-90% by weight of water) and may contain any of the other ingredients typically used in laundry rinses, e.g., minor amounts of materials such as dyes and perfumes and sometimes an alcohol, such as ethanol, to prevent phase separation, as well as the novel fabric softener mixture.
- the rinse may be prepared as such rinses are normally prepared except for the use of the novel mixture as the fabric softener; and conventional techniques are also suitable for rinsing laundry therewith.
- All of the laundry rinses of the invention regardless of the particular proportionation of DTMAC and N-octadecyl-N,N-dimethylamine oxide within the specified ranges, have the advantage of providing laundered fabrics, such as cotton, with better rewettability than laundry rinses containing only one component of the fabric softener mixture; but optimum rewettability is obtained when the fabric softener is a mixture of 75% by weight of the quaternary ammonium chloride and 25% by weight of the amine oxide.
- a laundry dryer sheet of the invention may be prepared by the conventional technique of soaking an absorbent flexible substrate with an aqueous mixture of the fabric softener mixture, pressing the resultant soaked sheet to remove any excess surfactant, and then drying it.
- it is preferably prepared by coating an absorbent flexible substrate with a molten mixture of the fabric softener components and then solidifying the mixture.
- the absorbent flexible substrate used in preparing the dryer sheets may be any of the substrates typically employed in making such sheets, since the only requirement for the substrate is that it be an absorbent material in sheet form.
- it may be a sponge, paper, or woven or non-woven cloth, especially a non-woven cloth made from fibers or filaments of a material such as wool, silk, jute, hemp, cotton, linen, sisal, ramie, rayon, cellulose esters, vinyl polymers, polyamides, and polyesters.
- a particularly desirable substrate is a sheet of non-woven polyethylene terephthalate cloth.
- All of the laundry dryer sheets of the invention in which the fabric softener is a mixture of 50-80% by weight of DTMAC and 50-20% by weight of N-octadecyl-N,N-dimethylamine oxide have the advantage of being able to impart greater softness to laundered fabrics, such as cotton, than can be achieved when either component of the mixture is used alone as the fabric softener.
- optimum reults are achieved when the fabric softener is a mixture of 75% by weight of DTMAC and 25% by weight of the amine oxide.
- the laundry dryer sheets in which the fabric softener is a mixture of 10-60% by weight of DTMAC and 90-40% by weight of any of the aforementioned N-octadecyl-N,N-dimethylamine oxide have the advantage of leading to the reduction of static charge buildup on laundered polyester fabrics or laundry batches comprising at least some polyester fabric when they are used in the drying step. In this case, optimum results are obtained when the fabric softener is a mixture of 50% by weight of DTMAC and 50% by weight of the amine oxide.
- a laundry batch composed of 23% polyester fabric, 46% cotton/polyester fabric, and 31% cotton fabric was washed on medium loading for 30 minutes in the presence of an anionic laundry detergent and then separated into five identical sub-batches.
- Each sub-batch was loaded into an automatic dryer, a polyester dryer sheet having a 1g loading of AO-18 and/or DTMAC fabric softener was placed into each of the automatic dryers on top of the sub-batch, and the sub-batch was then dried for 60 minutes on "normal" at about 65° C.
- the antistatic activity of the fabric softener in each dryer sheet was then determined in accordance with CSMA test protocol Method D-13F by removing the separate pieces of laundered fabric from the dryer, dropping them into a Faraday cage, and recording the initial voltage -- the test being performed on a day when the relative humidity was 50% at 22° C.
- the amounts of AO-18 and DTMAC used in the fabric softener and the results of the softness test are shown in the Table following the examples.
