ABSTRACT:
The present invention relates to blooming type compositions. Blooming is a property exhibited by dilutable compositions such as known cleaning compositions, specifically pine-oil type cleaning compositions which contain a significant amount (generally at least about 5% and more) of pine oil which includes a significant proportion of terpene alcohols. Certain phenolic disinfectant compounds, such as LYSOL disinfectant concentrate (Reckitt & Colman, Inc., Montvale N.J.) also exhibit such a blooming property. Blooming may be characterized as the formation of milky, creamy or cloudy appearance which is manifested when a dilutable composition is added to a larger volume or quantity of water. Blooming is an important characteristic from a consumer standpoint as it provides a visual indicator and impression to the consumer that the concentrated product contains active cleaning and/or disinfecting constituents which are released upon addition of the concentrate to a volume of water. Such is an important visual indicator of apparent efficacy of a concentrated product.
While presently commercially available materials have advantageous features, they are not without their attendant shortcomings as well. For example, the use of pine oil, and its pungent characteristic odor is frequently not desired. A further disadvantage is that the use of significant amounts of pine oil in a composition is desirably avoided as the pine oil is know to deposit a sticky residue on hard surfaces, which is particularly undesirable from a consumer standpoint. Also, many such compositions frequently are directed to providing a cleaning effect, and do not provide an appreciable sanitizing effect.
It has now been found that it is now possible to produce certain concentrate compositions utilizing these selected constituents in particular formulations which provide blooming type cleaning compositions in a concentrated liquid form which feature a good blooming effect, and which do not include any significant proportion pine oil, (i.e., less than 0.1% wt., preferably not more than 0.05% wt. and most preferably 0% wt.) but which provide a blooming effect. The “blooming” observed may be described as the change of the water's appearance from essentially colorless and transparent to that of a milky white or milky yellowish white, cloudy appearance. This effect is also sometimes referred to as the “break”. Such blooming is a highly desirable in blooming type cleaning compositions as consumer/end user expectations associate cleaning effectiveness with the extent and degree of this blooming upon formation of a cleaning composition. Such blooming is particularly desirable in compositions where the blooming characteristic in an aqueous dilution is long lasting.
Accordingly it is among the objects of the present invention to provide blooming type concentrate compositions wherein the blooming characteristic is based on certain essential oils in conjunction with the specific system of surfactants and organic solvents described in more detail below. It is also among the objects of the invention to provide processes for the production of such provide blooming type concentrate compositions as well as methods of treating hard surfaces using them.
Accordingly in one aspect of the invention there is provided an aqueous concentrated liquid hard surface cleaning composition which blooms when added to a larger volume of water which comprises the following constituents:
botanical oil constituent;
at least one botanical oil solubilizing surfactant, preferably an amine oxide surfactant constituent;
a binary solvent system which includes at least one organic alcohol constituent and at least one glycol solvent constituent;
an alkyl diphenyl solvent;
optionally but frequently desirably, a carboxylate constituent;
optionally but desirably an effective amount of a chelating agent which includes at least one non-ionized acetate group, most preferably a mono-, di- or tri- alkali or alkaline ethylenediaminetetraacetic acid;
optionally but desirably at least one optional constituent selected from: further chelating agents, coloring agents, light stabilizers, fragrances, thickening agents, hydrotropes, pH adjusting agents, pH buffers one or more detersive surfactant constituents particularly nonionic and amphoteric surfactants, as well as others known the art. The one or more optional constituents are selected to be present, and are included in amounts which do not undesirably affect the overall blooming characteristics of the present inventive compositions;
and the balance of the compositions being water.
In preferred embodiments the concentrate compositions provide excellent initial blooming characteristics in ‘as mixed’ dilutions with water.
It is a further object of the invention to provide such a concentrated liquid disinfectant composition wherein the composition exhibits a blooming effect when diluted in a larger volume of water.
It is among the further object of the invention to provide such a concentrated liquid disinfectant composition wherein the composition exhibits good long term stability, i.e., shelf stability in its concentrated form.
As an essential constituent in the concentrate compositions according to the present invention there are present one or more botanical oils, sometimes also referred to as “essential oils” which are useful in providing a blooming effect. By way of non-limiting example these include one or more of: Anethole 20/21 natural, Aniseed oil china star, Aniseed oil globe brand, Balsam (Peru), Basil oil (India), Black pepper oil, Black pepper oleoresin 40/20, Bois de Rose (Brazil) FOB, Borneol Flakes (China), Camphor oil, White, Camphor powder synthetic technical, Canaga oil (Java), Cardamom oil, Cassia oil (China), Cedarwood oil (China) BP, Cinnamon bark oil, Cinnamon leaf oil, Citronella oil, Clove bud oil, Clove leaf, Coriander (Russia), Coumarin 69° C. (China), Cyclamen Aldehyde, Diphenyl oxide, Ethyl vanilin, Eucalyptol, Eucalyptus oil, Eucalyptus citriodora, Fennel oil, Geranium oil, Ginger oil, Ginger oleoresin (India), White grapefruit oil, Guaiacwood oil, Gurjun balsam, Heliotropin, Isobomyl acetate, Isolongifolene, Juniper berry oil, L-methhyl acetate, Lavender oil, Lemon oil, Lemongrass oil, Lime oil distilled, Litsea Cubeba oil, Longifolene, Menthol crystals, Methyl cedryl ketone, Methyl chavicol, Methyl salicylate, Musk ambrette, Musk ketone, Musk xylol, Nutmeg oil, Orange oil, Patchouli oil, Peppermint oil, Phenyl ethyl alcohol, Pimento berry oil, Pimento leaf oil, Rosalin, Sandalwood oil, Sandenol, Sage oil, Clary sage, Sassafras oil, Spearmint oil, Spike lavender, Tagetes, Tea tree oil, Vanilin, Vetyver oil (Java), Wintergreen. Each of these botanical oils is commercially available. As noted previously, the inventive compositions do not include pine oil in any significant amount, although pine oil is known to the prior art to provide blooming effects.
Particularly preferred oils include those which are exemplified by the examples, following, and include: peppermint oil, lavender oil, bergamot oil (Italian), rosemary oil (Tunisian), and sweet orange oil. These may be commercially obtained from a variety of suppliers including: Givadan Roure Corp. (Clifton, N.J.); Berje Inc. (Bloomfield, N.J.); BBA Aroma Chemical Div. of Union Camp Corp. (Wayne, N.J.); Firmenich Inc. (Plainsboro N.J.); Quest International Fragrances Inc. (Mt. Olive Township, N.J.); Robertet Fragrances Inc. (Oakland, N.J.).
These oils may be present in the compositions in any amounts which are effective in providing a desirable blooming effect. Generally amounts from as little as 0.001% wt. to amounts of 20% wt. are useful, based on the total weight of the concentrated liquid disinfectant composition. More preferably these oils are present in amounts of from 0.01-15% wt., still more preferably 0.1-15% wt., and most preferably in amounts of from 1-10% wt. Of course, more a plurality of oils may be used.
A further constituent according to the invention is an organic solvent which is present in addition to the botanical oil which i
