Wrinkle spray is fast drying, readily biodegradable, and safe for use on clothing and in the home. It may be pump or trigger spray applied, applied via a pre-compression sprayer, pressurized industrial spray pump mechanism, or by any other acceptable method.
Early de-wrinkling inventions seemed confused in that they often describes alcohols, silicones, surfactants and other ingredients as fiber lubricants and describe water as merely the “carrier” for these active chemicals. Although novel, our invention specifically recognized that water plays an important role in relaxing and reducing wrinkles, and that it always has. Please, consider that steaming fabric is the best way to achieve wrinkle reduction and relaxation. In the steaming process, water vapor penetrates the fabric weave to swell and relax fibers into their original relaxed state. Wrinkle Spray mimics the de-wrinkling effect of steam by facilitating the penetration of extremely fine particles sprayed to swell and re-align fibers to their original relaxed configuration/orientation.
We use process quality softened, filtered (de-ionized) water conditioned to remove hard water deposits, namely calcium and magnesium carbonates. Wrinkle Spray is introduced to the garment, fabric and/or commercial fibrous weave by a very fine mist spray, produced by many acceptable means, but preferably from a pre-compression pump or trigger sprayer. A pre-compression sprayer sprays a uniform, fine vapor-like mist without drips, spitting or non-uniform droplets which, in past inventions caused spots or discoloration on fabrics, especially fine fabrics. Pre-compression sprayers deliver a uniform mist with droplet particle sizes in the range of several microns to sub-micron sizes. The smaller the droplet, the greater likelihood of an effective delivery of Wrinkle Spray without waste, spotting or local over-saturation. The smaller the droplet the more likely it is that Wrinkle Spray de-wrinkles like steam. Wrinkle Spray is spray applied to garments from approximately eight to twenty four inches away.
Prior compositions would have likely been poorly applied either by aerosol cans which are no longer accepted delivery (spray) mechanisms or by spray heads that either spit at low trigger pressures or at the end of some or all of the trigger strokes. Spitting the compositions of the early inventions likely caused local over-saturation, spotting and possibly local discoloration, especially with fine fabrics, and sensitive, natural, native or vintage dyes. Industry tests of the P&G product’s delivery mechanism shows that it spits. Spitting causes local over-saturation which causes dye bleeding or cellulosic browning. Spitting can create discolored spots that ruin a fabric or garment. One earlier invention used a pre-compression sprayer, but the composition was not color-safe as it was neutral pH or even slightly basic – just the opposite of what is desired.
Wrinkle Spray advances the art of de-wrinkling by the addition of an acidic component serving several purposes: 1) to neutralize any post-laundry alkalinity; 2) to stabilize sensitive colors; 3) to enhance the feel and “hand” of a fabric; and 4) to prevent fugitive dye bleeding and cellulosic browning. We also believe that Wrinkle Spray advances the art of de-wrinkling in that we recognize that water does the work of de-wrinkling and that the addition of surfactants, alcohols and other chemicals merely function to allow water to do its job of swelling and allowing fibers to regain their original relaxed configuration.
Wrinkle Spray also brings to the art of de-wrinkling the low-level energy input of gently brushing the consumer’s free hand across the fabric or gently shaking the clothes hangar upon which the treated garment rests soon after Wrinkle Spray is applied to enhance de-wrinkling. Allow a few seconds for Wrinkle Spray to penetrate the fabric weave and go to work to remove wrinkles. Over a short time and/or enhanced by any acceptable slight manual manipulation of the fabric, wrinkles are gone. The user may also hand form a crease in a fabric or garment to achieve the opposite, but desired result of making a wrinkle (crease).
Wrinkle Spray includes a surfactant or surfactants in much smaller concentrations compared to the earlier inventions. Surfactants (or, surface acting agents) when added to process quality softened, filtered water help reduce surface tension which greatly enhances the introduction of misted Wrinkle Spray into the fabric medium. Wrinkle Spray includes linear alcohol ethoxylate surfactants that are extremely effective wetting agents at very low concentrations. Linear alcohol ethoxylates are also readily biodegradable which eliminates concerns that the chemicals will linger in the environment.
Early similar compositions often characterized alcohol as a fellow lubricant, something that imparts a lubricating coating to fabric fibers. In Wrinkle Spray, alcohol is recognized to: 1) reduce the viscosity of the composition and lubricate fibers in the fabric weave; and, 2) facilitate drying of the fabric weave. A reduction in viscosity results because alcohol lowers the vapor pressure of the composition. Lowering viscosity enhances wetting of fibers because it promotes small droplet formation as the composition leaves the pre-compression sprayer. A lower viscosity also promotes an ease of penetration of, and wetting and lubricating the fibers. Equally important however, is the role of alcohol in drying the fabric, very quickly after the composition is applied. Drying takes place as alcohol’s evaporation lowers the vapor pressure at the fabric surface. Acceptable low molecular weight, water-soluble alcohols/solvents include ethanol, propanol, and isopropanol and mixtures thereof. n-Propanol is preferred, but may be admixed with other similar low molecular weight alcohols.
Tests between Wrinkle Spray and the P&G product have demonstrated that Wrinkle Spray has the fastest drying times heretofore claimed. Comparative tests clearly demonstrate a drying rate that is less than one half the other products drying time. Wrinkle Spray provides a practical drying period from application to use that allows the user to wear the garment shortly after de-wrinkling, or at what we like to call “household speeds.” Tests have demonstrated drying times of thirty to sixty seconds for fine fabrics and from less than one minute to several minutes drying times for heavier fabrics. Clearly, Wrinkle Spray delivers the most practical drying times to date.
Wrinkle Spray also introduces another novel and practical feature to the art of de-wrinkling. That is, purposefully lowering the pH to protect against dye bleeding, which in turn brings the added benefits of making the fabric feels softer, making the fabric wear against your skin gentler, and mitigating against wash detergent residues. An acid or combinations of acids are acceptable for this purpose, at effective levels that lower the pH of the composition to protect against dye bleeding. While the acid may be selected from a group consisting of, (i) glycolic (ii) citric (iii) glacial acetic (iv) tartaric (v) oaxalic (vi) sulfamic (vii) sulfuric, and (viii) phosphoric, the acid in the Wrinkle Spray is pure glycolic acid, in such concentrations to lower the pH of the composition to ensure color-safeness. By lowering the pH, Wrinkle Spray can be applied on all types of casual to fine fabrics without concerns about dye bleeding, without causing fugitive dyes to run, without affecting natural, native, or vintage dyes, and without promoting cellulosic browning. In industrial uses, Wrinkle Spray will also de-wrinkle and prevent changes in the color of commercial fabrics.
Acidic solutions, rinses or souring agents have been used on such delicate, natural or vintage fabrics eliminate or mitigate against the potential for ill-effects during cleaning. Lowering the pH of our compositions applies these well-known principals to this field.
Neutral or higher pH will foster or promote bleeding of fugitive dyes, natural dyes, native dyes and vintage dyes, as well as promote cellulosic browning. Wrinkle Spray is purposefully buffered to a pH that protects fugitive dyes, natural and native dyes, and vintage dyes. This adjustment of pH provides a novel, practical, safety factor in that Wrinkle Spray (and its companion products) now actively protects even the most sensitive colors and delicate fabrics by stabilizing all dyes.
Another novel and practical feature is the addition of an optional malodor-eliminating compound to Wrinkle Spray that keeps fabrics fresh longer, or refresh malodorous garments by eliminating, or coupling with, malodorous compounds to deodorize them. These carefully constructed semi-rigid, concave molecular structures; complexes that synergistically combine numerous active ingredients into a proven safe and effective deodorizer that chemically modifies malodors, are present in Wrinkle Spray in very small, but effective concentrations. Custom blended fragrances are added to Wrinkle Spray to help mask the alcohol scent and to provide a pleasant identifying experience when a consumer uses Wrinkle Spray. The addition of an acid to lower pH also allows the composition to remain stable under any routine consumer environmental condition without preservatives.
A recent Good Housekeeping article featured Proctor & Gamble’s ‘Downy Wrinkle Releaser.’ The article praised the de-wrinkling effort of the product, but noted that it took 27 minutes for the treated garment to dry.
Wrinkle Spray is safe on all fabrics and its pleasant scent will not linger or interfere with other fragrances. Simply follow the directions on the bottle. The garment will dry in just a minute, probably less. Wrinkle Spray’s ability to remove malodors from garments allows you to extend wear, especially extending the wear of dry clean garments, and it will not interfere with desirable fragrances.
