Description

BACKGROUND

1. Field

The disclosure of the present patent application relates to disinfectants, and particularly to hand foam sanitizers and hand gel sanitizers containing disinfecting capsules.

2. Description of the Related Art

Unclean hands play an important role in the transmission of pathogens. Infection may occur when hands contaminated with pathogens touch the eyes, nose or lips, allowing microorganisms to enter through the mucous membranes thereof. Numerous studies support hand hygiene as being an important factor in reducing the carrying and transmission of pathogens on hands to prevent disease transmission and infection. However, according to the Centers for Disease Control and Prevention (CDC), only about 5% of people wash their hands long enough to destroy infectious germs after using the bathroom.

Although a wide variety of hand washing devices and accessories exist, such as devices to monitor hand washing process or assist in hand washing for periods of about 15 seconds to remove germs, such devices and accessories are not widely used, as they are typically costly and difficult to install. Further, as with conventional washing, there is no certainty that the devices will be used, despite their presence and obvious utility.

The use of both alcohol-based and alcohol-free antimicrobial hand gel and hand foam is another commonly used method for hand disinfection, particularly due to their convenience, low costs, and ease of application. However, alcohol-based hand sanitizers often leave the skin dry, and with repeated use, cause skin irritation. On the other hand, many alcohol-free products leave sticky residue on the skin. Another, disadvantage is that the sanitizers do not last long and disinfection lasts for only a short time. Thus, a hand sanitizer and method of making the same solving the aforementioned problems is desired.

SUMMARY

The hand sanitizer may be a hand foam sanitizer or a hand gel sanitizer. Each of the hand sanitizers includes at least one stabilizing agent, at least one skin care agent, and a volume of disinfecting micelle capsules suspended therein. Each disinfecting capsule has a polymer shell which defines a hollow core. The polymer shell includes an antimicrobial material. The antimicrobial material may have a concentration of between 0.5 wt % and 95 wt % of the polymer shell. In order to make the hand foam sanitizer, at least one foaming agent is added to produce a foam by air foaming. Preferably, the at least one foaming agent and the at least one stabilizing agent are selected to maintain a size and shape of the foam for at least 60 seconds at room temperature (25° C.).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The hand sanitizers include formulations for water-based hand sanitizers, such as hand foams and hand gels, which are effective for killing germs and microbes. The hand sanitizers disinfect by contact-killing, anti-adhesion and/or release-killing, and can further store and release fragrance and skin-care ingredients over time. The hand sanitizers contain disinfecting capsules of micelles structures, which store active disinfectants, fragrances, and/or skin-care ingredients within an encapsulating shell. The shell possesses one or more antimicrobial properties, such as contact-killing, anti-adhesion and/or anti-biofilm. The encapsulating shell also controls the dosing of the stored disinfectants, fragrances and/or skin-care ingredients, thus prolonging their effectiveness. The hand sanitizers provide long-term protection against germs and microorganisms.

The disinfecting micelle capsules include an antimicrobial polymeric shell and a core-space for storing active disinfectants, fragrance and skin-care ingredients that are slow-released to provide long-term performance. The formulations of the hand sanitizers, as will be described in greater detail below, include ingredients such as disinfectants, fragrances, polymers, foaming agents and stabilizers, thickener and viscosity enhancers, and skin-care ingredients that provide moisturizing and/or skin repair and/or emollient and/or vitamin for care of the skin.

The stored disinfectants include, but are not limited to, common disinfectant solutions, such as alcohol, chlorhexidine and other chemical or mineral disinfectants, as well as phytochemicals that exhibit antimicrobial properties, including essential oils and their active antimicrobial components. The essential oils include, but are not limited to, agarwood oil, cajuput oil, cananga oil, cinnamon bark oil, citronella oil, clove oil, eucalyptus oil, fennel oil, ginger oil, kaffir lime oil, nutmeg oil, ollium xanthorrhiza oil, origanum oil, patchouli oil, rosemary oil, sandalwood oil, tea tree oil, thyme oil, vetiver oil or other plant-derived extracts that exhibit antimicrobial properties.

The stored fragrances include, but are not limited to, natural and synthetic essence of flowers, fruits and aromatic woods that are pleasant to smell and provide olfactory pleasure. Fragrance may also be added to provide an olfactory cue for the presence of the disinfection function. The stored skin-care ingredients include, but are not limited to, moisturizers, such as hyaluronic acid, sodium hyaluronic, vitamin E, ceramides, sodium PCA, glycerin, glycerol, silicones, petrolatum, salicylic acid, alpha hydroxy acids and others with similar functions or properties; active ingredients that promote skin repair, such as vitamin C, hyaluronic acid, beta-glucan, ceramides, shea butter and others with similar functions or properties; emollients, such as mineral oil, plant butters (e.g., shea and cocoa), lanolin, petrolatum, paraffin, beeswax, squalene, cetyl alcohol, triethyhexanoin and others with similar functions or properties; vitamins, such as vitamins A, C, E, D, K, B3, B5; and anti-oxidants, such as vitamin C, choline, catechins and others with similar functions or properties. The stored materials may be a combination of one or more disinfectants, fragrances, and/or skin-care ingredients that are slowly released over time.

The shell of the micelles structure is formed of polymers with antimicrobial properties and the ability to release the stored materials over time. Polymers with one or more antimicrobial properties form 0.5 to 95 wt % of the shell material and include, but are not limited to, anionic, cationic and nonionic polymers, where the polymers may contain primary, secondary and tertiary amines, zwitterionics, or quarternary ammoniums. Some examples include, but are not limited to, polyethylenimine (PEI), polyquarternium, polyhexamethylene biguanide (PHMB), poly(diallyldimethylammonium chloride (PDDA), functionalized chitosan (CHI) or similar polymers with bactericidal, virucidal or sporicidal activities. The chemical structure for the exemplary polyethylenimine (PEI) is shown below:

The disinfecting capsules form a micelles structure and a stable colloid that is incorporated in the formulation of water-based hand sanitizers as an antimicrobial ingredient, providing prolonged disinfection and also releasing fragrances and/or skin-care ingredient over time. The formulations for the water-based hand foam sanitizers, as will be described in greater detail below, include the disinfecting capsules, foaming and stabilizing agents and skin-care ingredients, which are suitable for air-foaming. The hand sanitizers may also include the disinfecting capsules, thickeners and viscosity enhancers, and skin-care ingredients, for producing a liquid gel for hand disinfection.

FIG. 1A shows disinfecting capsules made from the exemplary antimicrobial polymer polyethylenimine (PEI), and FIG. 1B shows disinfecting capsules made from the exemplary combination of PEI and polyhexamethylene biguanide (PHMB). FIGS. 1A and 1B are each 500× magnifications. The sizes of the capsules are tunable using surfactants and co-solvents, such as, for example, alcohols. This can be seen in FIGS. 2A, 2B and 2C, with 0 wt %, 0.1 wt % and 0.2 wt % sodium dodecyl sulfate (SDS) as a surfactant, respectively. FIGS. 2A, 2B and 2C are each 200× magnifications. The disinfecting capsules without stored disinfectants are active for disinfection of microorganisms, as shown in FIG. 3. In FIG. 1A, the PEI disinfecting capsules are referred to herein as capsules Al, as will be described in detail with reference to Example 1 below. The combination PEI and PHMB capsules of FIG. 1B are referred to herein as capsules D1, as will be described in greater detail with reference to Example 10 below. Each of the capsules shown in FIGS. 2A, 2B and 2C are referred to herein as capsules D3, as will be described in greater detail in Example 12 below. FIG. 3 compares the bactericidal properties of capsules A1 (Example 1), B1 (Example 4), C1 (Example 7), D1 (Example 10), E1 (Example 13), and F1 (Example 16).

FIG. 4 is a 200× magnification showing a suspension of capsules A1 in thyme oil, and FIG. 5 is a 200× magnification showing a suspension of capsules A1 in farnesol. It can be clearly seen that the capsules are larger with the stored disinfectants. FIG. 6 shows the bactericidal properties of the A1-farnesol suspension for contact of 60 seconds with 10⁵ S. aureus, comparing a control sample against empty A1 disinfecting capsules (S0), A1 capsules with 35 ppm farnesol (S1), A1 capsules with 70 ppm farnesol (S2), A1 capsules with 350 ppm farnesol (S3), and A1 capsules with 700 ppm farnesol (S4). FIG. 6 further illustrates the storage capability of the disinfecting capsules and the release of the active content. The S0 sample shows a 90% reduction in viable bacteria, the S1 sample shows a 97% reduction in viable bacteria, the S2 sample shows a 97.5% reduction in viable bacteria, the S3 sample shows a 98.8% reduction in viable bacteria, and the S4 sample shows a 99.25% reduction in viable bacteria.

The formulation of Example 38 (formulation 1) below is an active sanitizer and, when applied, achieved better than 99% decrease in viable E. coli (10⁵ CFU) within 60 seconds of contact. The formulation contained disinfecting capsules A1. A colorant can be added to the hand sanitizer to produce foams of different colors. Disinfecting capsules containing thyme oil are also stable and can produce stable foam.

Hand disinfection was performed according to the following procedure: The hands were sanitized with 75% vol. of ethanol for 15 seconds, rinsed with tap water for 20 seconds, and dried with two pieces of clean paper towel, followed by 1 minute of air drying. The fingertips on the left hand were sampled. Afterward, 1 milliliter of foam was applied and spread evenly over the hand and dried by rubbing the hands together. A suspension containing ten microliters of E. coli (10⁶ CFU) was evenly spread over a 1 cm² area of each fingertip. The fingertips were then sampled, one after the other, following 3, 5, 10, 15 and 30 minutes of bacterial challenge. The sampling was done by gently pressing the fingers onto agar and rolling it for 5 seconds. The recovered viable E. coli was then counted. The experiment was carried out in triplicate. This was followed by a series of experiment where the bacteria was challenged on the fingertips after 5, 60, 120, 180 and 240 minutes of using the sanitizers. FIGS. 7A, 7B, 8 and 9 show that the hand foam sanitizers have persistent disinfection properties and can keep the hands clean from microbial contamination up to 4 hours after usage. It can be seen that the recoverable E. coli was less than 1.2% on hands disinfected with the hand foam sanitizers. FIG. 7A shows the bactericidal activity of a hand foam sanitizer made from formulation 2 of Example 39 below as a function of contact time for samples applied over 5, 60, 120, 180 and 240 minutes before the test. FIG. 7B is a comparison using the same parameters for a conventional alcohol-based hand sanitizer. For each of FIGS. 7A and 7B, the measured bactericidal activity was against 10⁵ CFU E. coli. FIG. 8 shows the bactericidal activity of a hand foam sanitizer made from formulation 10 of Example 47 below as a function of contact time for samples applied over 5, 60, 120, 180 and 240 minutes before the test. The measured bactericidal activity was against 10⁵ CFU E. coli. FIG. 9 shows the bactericidal activity of a hand foam sanitizer made from formulation 11 of Example 48 below as a function of contact time for samples applied over 5, 60, 120, 180 and 240 minutes before the test. The measured bactericidal activity was against 10⁵ CFU E. coli.

FIG. 10 shows that a hand gel sanitizer using the disinfecting capsules also possessed similarly high bactericidal activities, even at a very short contact time of 30 seconds. In FIG. 10, the “a” sample represents a control, the “b” sample shows contact of 30 seconds using a hand gel sanitizer with formulation 8 of Example 45 below, and the “c” sample shows contact of 60 seconds using the hand gel sanitizer with formulation 8 of Example 45 below. The measured bactericidal activity is >99% against 10⁵ CFU E. coli.

As a further alternative, a hand foam sanitizer may be prepared by providing a skin care ingredient-containing solution separately from a suspension containing the at least one foaming agent and the volume of disinfecting capsules suspended therein. The skin care ingredient-containing solution can then be selectively mixed with the suspension at a desired ratio. It should be understood that the skin care ingredient(s) and foaming agent(s) may be any desired skin care ingredient(s) and foaming agent(s), such as those described with regard to the previous embodiments.
