## Background
CLAIM FOR PRIORITY
This application is a continuation of U.S. Non-provisional patent application Ser. No. 11/304,353 entitled, “Antimicrobial Liquid Hand Soap Compositions with Tactile Signal”, filed on Dec. 15, 2005, now U.S. Pat. No. 7,521,404. Application Ser. No. 11/304,353 was based on U.S. Provisional Patent Application Ser. No. 60/637,101, of the same title, filed Dec. 16, 2004. The priorities of U.S. Non-provisional patent application Ser. No. 11/304,353 and U.S. Provisional Patent Application Ser. No. 60/637,101 are hereby claimed and the disclosures thereof are incorporated into this application by reference.


TECHNICAL FIELD
The present invention relates generally to liquid hand soap compositions and in a preferred embodiment to a liquid soap including at least two anionic surfactants and a glutinous additive such as a cationic phospholipid surfactant having a relative contact angle value with water of at least about +10° with respect to other ingredients. The phospholipids act as a tactile signal; promoting more thorough hand cleansing.
BACKGROUND OF THE INVENTION
Media attention to cases of food poisoning, strep infections, and the like due to microbial contamination has increased public awareness of the dangers posed by inadequate hygiene, particularly in the food service and health industries. Bacteria found on the skin can be divided into two groups: resident and transient bacteria. Resident bacteria are Gram positive bacteria which are established as permanent microcolonies on the surface and outermost layers of the skin and play an important, helpful role in preventing the colonization of other, more harmful bacteria and fungi. Transient bacteria are bacteria which are not part of the normal resident flora of the skin, but can be deposited when airborne contaminated material lands on the skin or when contaminated material is brought into physical contact with it. Transient bacteria are also typically divided into Gram positive and Gram negative subclasses. Gram positive bacteria include pathogens such as Staphylococcus aureus, Streptococcus pyogenes and Clostridium botulinum. Gram negative bacteria include pathogens such as Salmonella, Escherichia coli, Klebsiella, Haemophilus, Pseudomonas aeruginosa, Proteus and Shigella dysenteriae. Gram negative bacteria are generally distinguished from Gram positive by an additional protective cell membrane which generally results in the Gram negative bacteria being less susceptible to topical antibacterial actives. The American Society of Microbiologists has indicated that adequate hand washing will greatly reduce the incidence of communicable diseases.
Many soap formulations have been developed which have an antimicrobial agent such as a suitable phenol as well as emollients. It is desirable that the hand washing formulation not only remove bacteria from the hands, but also leave behind an antibacterial protective layer that also softens and conditions.
United States Patent Application 2002/0141959 and U.S. Pat. No. 6,613,755, both to Peterson et al., disclose antimicrobial skin preparations containing organosilane quaternary compounds that remain on the skin, are substantive to it and reduce or eliminate bacteria, viruses and fungi present and prevent future contamination by their presence. Antimicrobial skin compositions are also disclosed in published United States Patent Application No. 2002/0103092, to Tashjian et al., which contain an anionic surfactant, an amphoteric surfactant, a cationic conditioning agent, an antibacterial agent and water.
High phospholipid-containing dermatological compositions are disclosed in United States Patent Application No. 2002/0012648 to Orthoefer. The relatively high concentration of phospholipids impart a thin macromolecular layer to the skin, which permits natural hydration while providing antioxidant and natural sun-blocking effects. Typical structures of these phospholipids are shown below in structure 1:




where R and R′ are fatty acids having the formula CH3(CH2)nCOO, with n equal to between about 4 and 22.

Phospholipids are also present in antimicrobial cleansing compositions described in United States Patent Application No. 2002/0002124 to Biedermann et al. The compositions are mild to the skin and provide improved antimicrobial protection. U.S. Pat. No. 6,451,775 to Smith et al. discloses novel castor oil amidopropyl dimethyl phospholipids as emulsifiers that are substantive to the skin and are well tolerated by human tissue:




where R represents the ricinoleic moiety:





A Colonial Chemical product bulletin (Feb. 13, 2003) discloses an antimicrobial hand cleanser containing 87% water, 8.5% disodium oleamido MEA sulfosuccinate, 2.5% cocamidopropyl phoshatidyl PG-dimonium chloride (ColalipidTM C) and 0.4% chlorhexidine gluconate as a biocide. That same bulletin describes ColalipidTM surfactants as unregistered antimicrobials and notes a frequent use hand soap composition with 2% ColalipidTM C.
U.S. Pat. No. 6,331,293, also to Smith et al. also discloses phospholipids:




U.S. Pat. No. 5,688,752, to Turner, describes various lipids for cleansing compositions that prevent or ameliorate skin dryness, skin wrinkling, chapping or ageing. Quaternized phosphate esters are included as ingredients in dry wash compositions that impart conditioning properties to the skin, as described in U.S. Pat. No. 5,683,683 to Scafidi. Phospholipids are used as “primary surfactants” in antimicrobial cleansing compositions described in U.S. Pat. No. 5,635,462 to Fendler et al. They are used to act upon or in conjunction with a substituted phenol to further enhance its antimicrobial activity. U.S. Pat. No. 4,753,749, to McIntosh, discloses microbiocidal cleaning agents containing amine alkyl phosphate additives as the active ingredients:




where:

R=an alkyl group containing 1 to 24 carbon atoms;

R1=an alkyl group containing from 1 to 3 carbon atoms; and

R2=an alkyl group containing from 1 to 5 carbon atoms.

In the preferred structure, R equals C12H25, R1 equals CH3 and R2 equals C2H5.

Washing of the skin, especially the hands, with antimicrobial soap formulations can remove many viruses and bacteria from the washed surfaces. Removal of the viruses and bacteria is due to the surfactancy of the soap and the mechanical action of the wash procedure. Therefore, it is known and recommended that the people wash frequently to reduce the spread of viruses and bacteria. Recent surveys, however, have revealed that while nearly 95% of people claim to have washed their hands after use of public restrooms, actual observations reveal that this figure does not exceed about 66%. Notwithstanding increased awareness, there is a tendency to rush the hand washing process which leads to inadequate hygiene. A number systems and devices to encourage longer and more thorough handwashing have accordingly been developed.
Collopy in United States Patent Application 2002/0061500 discloses a hand-washing device containing a display panel that encourages the user to wash their hands for about 15 seconds to remove germs. Gorra, U.S. Pat. No. 5,945,910 discloses method and apparatus for monitoring and reporting hand washing, which includes a sensor for signaling the dispensation of a cleaning agent from a dispenser, and a reporting and monitoring module. Allen et al. U.S. Pat. No. 5,781,942 discloses wash stations and method of operation, which monitors hand washing and assists in hand washing. These systems are relatively expensive and difficult to implement; oftentimes involving training and monitoring personnel. Even when such steps have been taken, there is little certainty that all personnel have followed proper washing procedures.
SUMMARY OF THE INVENTION
It has been found in accordance with the invention that adding a surfactant having glutinous (somewhat oily yet somewhat unctuous as well) tactile properties to conventional hand soap formulations promotes longer hand washing and rinsing times leading to better hygiene, without complex hardware and software and without substantial implementation expense. There is thus provided in one aspect of the invention an antimicrobial liquid hand soap composition comprising: (a) water; (b) a primary hand soap composition, including a biocide; and (c) a glutinous surfactant component having a relative contact angle value with water of at least about +10 degrees with respect to the primary hand soap composition, the glutinous surfactant being present in an amount effective to alter the tactile properties of the primary soap composition, with the proviso that the glutinous surfactant is present in an amount of less than about 20 weight % based on the combined dry weight of the primary hand soap composition and the glutinous surfactant. In a series of preferred embodiments, the glutinous surfactant component is preferably selected from the group consisting of: cocamidopropyl PG-dimonium chloride phosphate; dimer dilinoleamido-propyl PG-dimonium chloride phosphate; sodiumgrapeseedamidopropyl PG-dimonium chloride phosphate; sodium olivamidopropyl PG-dimonium chloride phosphate; linoleamidopropyl PG-dimonium chloride phosphate; PEG-8 dimethicone sunfloweramidopropyl PG-dimonium complex; sunfloweramidopropyl phosphate PG-dimonium chloride and mixtures thereof.
Preferably, the glutinous surfactant component has a relative contact angle value with water of at least about +20° with respect to the primary soap composition; while in most cases the glutinous surfactant is present in an amount of from about 1% to about 10% based on the total (wet) weight of the composition. In particularly preferred cases, the glutinous surfactant is present in an amount of from about 3% to about 7% based on the total weight of the composition and the primary soap composition comprises at least two anionic surfactants. Optionally, the primary soap composition includes at least one nonionic surfactant.
While any suitable biocide may be used, preferred are those which include halogenated aromatic compounds. One preferred ingredient, for example, is:




A chelating agent such as EDTA or the like is optionally provided along with glycerine or other conventional components for liquid soaps.

Another antimicrobial liquid hand soap composition of the invention includes: (a) up to about 75% by weight water; (b) a primary hand soap composition, including a biocide; and (c) a glutinous surfactant component having a relative contact angle value with water of at least about +10° with respect to the primary hand soap composition, the glutinous surfactant being present in an amount effective to alter the tactile properties of the primary soap composition.
Still yet another embodiment of the invention is an antimicrobial liquid hand soap composition comprising: (a) water; (b) a primary hand soap composition; and (c) a glutinous surfactant component having a relative contact angle value with water of at least about +10° with respect to the primary hand soap composition, the glutinous surfactant being present in an amount effective to alter the tactile properties of the primary soap composition, with the proviso that the glutinous surfactant is present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water.
There is provided in still yet a further aspect of the invention an antimicrobial liquid hand soap composition comprising: (a) water present in an amount of up to about 75% by weight; (b) a primary hand soap composition; and (c) a glutinous surfactant present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water, the glutinous surfactant being operative to increase rinse time with respect to a like composition consisting of water and the primary soap composition. Preferably, the glutinous surfactant is operative to increase rinse time at least 10% with respect to a like composition consisting of and the primary soap composition; 15 or 20 percent increases in rinse time are preferred.
The inventive compositions are typically made by preparing a mixture of: (a) water in an amount of up to about 75% by weight of the composition; (b) a primary hand soap composition; and (c) a glutinous surfactant wherein the glutinous surfactant is present in an amount of at least about 3% by weight and up to about 10% by weight based on the weight of the composition including water and wherein the glutinous surfactant alters the tactile properties of the composition so as to lengthen hand cleansing times.
Still yet other advantages of the invention will become apparent from the discussion which follows.


DETAILED DESCRIPTION OF THE INVENTION
The invention is described in detail below for purposes of illustration, only. Modifications within the spirit and scope of the invention, set forth in the appended claims, will be readily apparent to one of skill in the art.
As used herein, terminology is given its ordinary meaning as supplemented below.
“Biocide” and the like terminology means and includes any substance that kills or inhibits the growth of microorganisms such as bacteria, viruses, molds, slimes, fungi, etc. Biocidal chemicals include halogenated aromatics, chlorinated hydrocarbons, organometallics, metallic salts, organic sulfur compounds, quaternary ammonium compounds, phenolics and the like.
“Like composition” refers to a composition which is substantially identical except that a specified component has been replaced with water, alcohol, polyol or mixture of such substitute components.
“Primary hand soap composition” refers to the collective ingredients of a soap composition of the invention exclusive of the glutinous surfactant component; optionally including a biocide. The primary soap formulation may be referred to on either a wet or dry basis. The primary hand soap composition typically includes one or more surfactants as the primary surfactants of the composition as well as preservatives, fragrances and so forth. The primary hand soap composition may contain anionic surfactants, cationic surfactants, nonionic surfactants and so forth. Examples of suitable conventional anionic surfactants generally include, but are not necessarily limited to, fatty acid soaps as well as sulfates, carboyxlates, sulfonates, sulfosuccinates, phosphonates, phosphates, sarcosinates and isethionates of hydrophobic moieties. Other suitable surfactants for the primary hand soap composition are surfactants selected from the group consisting of amine oxides, phospholipids, partially neutralized carboxylic acids and diacids, betaines, ethoxylated methylglucosides and mixtures thereof. The amount of primary surfactant(s) to be added to the composition of the present invention is somewhat dependent upon the number of primary surfactants added. However, the amount of all of the primary surfactants together generally will not exceed more than about 20-25% by weight of the composition including water.
“Primary surfactant” means a surfactant included in the primary hand soap composition.
“Glutinous surfactant composition” means one or more surfactants added to the primary hand soap composition in order to alter its tactile properties. Some preferred surfactants are available from Colonial Chemical and are listed below in Table 1.

The composition may also include other additives such as thickeners, emollients, chelating and sequestering agents, fragrances, coloring agents, opacifying agents, pearlizing agents, vitamins and the like. For example, the composition may include a polymer viscosifier or thickener such as hydroxyethyl cellulose to make the composition more aesthetically pleasing. Examples of other suitable polymer viscosifiers include, but are not necessarily limited to, hydroxypropyl cellulose, methylcellulose, and carboxymethyl cellulose. Examples of suitable chelating agents for the present invention are ethylenediaminetetra-acetic acid (EDTA), and its salts such as tetra sodium EDTA. An example of a particular pearlizing agent is ethylene glycol distearate. Generally, these additives are used in amounts, which do not affect the essential nature of the composition with respect to its antimicrobial properties.
The angle defined between a tangent to a liquid droplet surface at its air/liquid interface at the droplet's line of contact with a solid and the solid substrate surface upon which the droplet rests (as measured through the liquid) is generally referred to as the contact angle of a liquid with a solid. The contact angle may be measured at any point at the line of contact of the three phases, air/liquid/solid. “Contact angles” herein refer to contact angles of coated paperboard with water at room temperature as measured with a goniometer. Inasmuch as contact angles decayed over time, the contact angle for purposes of determining relative contact angle with respect to reference compositions is taken at 1 second of contact time, preferably averaged over at least 5 trials.
The relative contact angle value with water with respect to a control composition is calculated as the difference between the measured contact angles with water of the test composition and the control composition at 1 second. Details appear in connection with Table 4.
EXAMPLES
Test composition A was prepared by blending water and the ingredients listed in Table 2 to produce an antimicrobial hand soap composition having the relative amounts shown.

A hydrophobic coated paperboard substrate was used to evaluate the relative contact angles of Hand Soap Formulation A, the various glutinous surfactants referred to above, as well as compositions of the invention which include a glutinous surfactant component in addition to the primary hand soap composition of Formulation A. To this end, a series of formulations were overcoated onto the paperboard substrate using a coil coating rod (#7); the films applied had a weight of about 8 g/m2, dry basis. A water droplet (0.01 ml) was placed on a dried film and contact angle over time measured with a Ramé-Hart Goniometer (Model #100-00115, equipped with a video camera, zoom lens and green light). All testing was at room temperature (approximately 20° C.) and films were dried for twenty-four hours prior to testing under ambient conditions. Inasmuch as contact angle decays rapidly in many cases, it is important that the instrument used is capable of measuring the angle accurately with respect to time. Note that particularly preferred surfactants such as ColalipidTM C and ColalipidTM C DLO exhibit relatively stable contact angle values by this method.
The relative contact angle value is calculated by subtracting the contact angle at 1 second of the control from the contact angle at 1 second from the test composition.
Results appear in Tables 4 and 5 below.

The data of Tables 4 and 5 are surprising when one considers that the various surfactants tested have relatively high HLB values; see Table 6.








TABLE 6





HLB Values for Selected Phospholipds


















COLALIPID TM C (coconut oil phospholipid
HLB 17-19



COLALIPID TM SAFL (linoleyl phospholipid)
HLB 17-19










Without intending to be bound by any theory, it is believed that the glutinous and ointment-like nature of the phospholipids increases contact angles of soap compositions despite the relatively high HLB values of the surfactants.

Even more surprising is the effect that these high HLB value surfactants have on cleansing times observed in panel testing, discussed below.
Twenty (20) female test panelists were recruited for purposes of testing the effect of the tactile-modifying component on hand washing time. The panelists were prompted to wash their hands normally including generally the steps of:

    
    
        (1) adjusting the running water temperature until they felt comfortable;
        (2) wetting their hands with warm water;
        (3) applying about 2 grams of soap on a their wet hands;
        (4) rubbing their hands with soap without running water;
        (5) rinsing their hands with warm running water; and
        (6) drying their hands with a paper towel.

Half of the panelists tested the control soap of Formulation A first, then the same soap with 5% ColalipidTM C (Example 10), while the order was reversed for the other 10 panelists.

    
    


The time from starting step (4) to the end of step (6) was recorded as the wash/rinse/drying time; the time from starting step (4) to the end of step (5) was recorded as the wash/rinse time and the time from the beginning of step (5) to the end of step (5) was recorded as the rinse time. In almost all cases, the test panelists reported a relatively “sticky” or glutinous feel to the soap of Example 10.
The results showed that the wash/rinse/drying time and wash/rinse time were slightly higher for the soap of Example 10 than for the soap without phospholipids additive, on the order of 5% or so; however, the effect on rinse time was dramatic. Results appear in Table 7:

In Table 7 it is sent that the soap with phospholipid induced an average increase in rinse time of over 27% over all of the testing. Closer examination of the results suggests that other factors, perhaps random, had an impact on panelist behavior; for example, Table 8 shows that when Formulation A was tested first, rinse times were longer than when sample A was tested second, a result which appears anomalous.
