Problems solved by technology

Therefore, the added humectants or skin protectants do not remain evenly distributed in the sanitizer, rendering the sanitizer's ability to retain moisture ineffective
In addition, the instability of the sanitizer can cause a large oily layer to form on the skin, thus the sanitizer may feel greasy and not aesthetically pleasing on the skin
Additional process steps are also required to incorporate humectants such as emollients or skin protectants directly into the sanitizer, adding complexity and cost to the manufacturing process

[0088] Preparation of Sanitizers

[0089] The moisturizing hand sanitizers of the present invention can be prepared by combining and mixing the high internal phase emulsion with other sanitizer ingredients at room temperature. Since emollients and / or silicones are added to the sanitizer as part of the high internal phase emulsion, no heat and other costly or time-consuming process steps are required to obtain a uniform final stable sanitizer Detergent composition. In addition to moisturizing hand sanitizers, the high internal phase emulsions described herein can also be used to form other stable alcohol-based personal care formulations.

[0090] Accordingly, in one embodiment, the present invention is directed to a method of making a moisturizing hand sanitizer or other stable alcohol-based personal care formulation. The method includes combining and mixing a high internal phase emulsion with water and alcohol as described herein. Generally, the sanitizer or other persona...

Embodiment 1

[0115] In this example, a moisturizing hand sanitizer of the present invention was prepared. The ingredients and amounts used to prepare each hand sanitizer are listed in Table 1.

[0116] Table 1

[0117]

[0118] The sanitizer is prepared by stirring water and carbomer for 10 to 20 minutes. During this time, half of the glycerin was combined with the hydroxypropyl cellulose and aloe vera powder and mixed for 10 minutes. Stir the glycerin mixture into the water mixture and add the remaining glycerin. The resulting mixture was stirred for 30 minutes. While stirring, a high internal phase emulsion (HIPE) consisting of petrolatum / dimethicone / ceth-10 / steareth-21 / poloxamer 335 (Dow 7-3111), and cause it to disperse. Panthenol, SD Ethanol 40-B, Tocopheryl Acetate and Fragrance are then added. The aminomethyl propanol is then added with stirring to give a gel of the sanitizer composition.

Embodiment 2

[0120] In this example, the effects of sanitizers 1 and 2 prepared in Example 1 on skin moisturizing were evaluated. A control hand sanitizer was also tested except that it had 31.85 wt.% water and no petrolatum / dimethicone / ceth-10 / steareth-21 / poloxane Contains the same composition ingredients as the hand sanitizer prepared in Example 1, except for the high internal phase emulsion (HIPE) of 335. Commercially available hand sanitizers were also tested Moisturizing leave-in hand sanitizer (available from Kimberly-Clark). Should Moisturizing leave-in hand sanitizer other than stated The hand sanitizer had a composition similar to the hand sanitizer prepared in Example 1, except that 1.80 wt.% of Polytrap 6500 (available from AMCOL Health & Beauty Solutions, Inc.) was substituted for the HIPE.

[0121] Six subjects were enrolled in this study (6). Individuals with abnormal skin pigmentation at the test site, skin disease on the test area of ​​the arm, skin lesions, skin le...

Abstract

The present disclosure generally relates to moisturizing hand sanitizers including alcohols that are effective in killing microorganisms while providing a moisturizing benefit to the user's skin. More particularly, the alcohol-based hand sanitizers include a high internal phase emulsion which allows moisturizers or skin protectants such as emollients and / or silicones to be stably incorporated into the sanitizer.

Description

Background of the invention [0001] The present invention generally relates to antimicrobial hand sanitizers comprising alcohols which, while effectively killing microorganisms, also provide moisturizing benefits to the skin of the user. More specifically, the alcohol-based hand sanitizer includes a high internal phase emulsion that allows for the stable incorporation of humectants or skin protectants such as emollients and / or silicones into the sanitizer in the dose. [0002] Consumers are familiar with the concept of so-called "microbes" and the spread of microbes. One of the best and easiest ways to prevent the spread of microorganisms and / or disease is by routinely washing an individual's hands. Recognizing that such hand washing is inconvenient or impossible in certain circumstances, such as travel environments and / or time constraints, many manufacturers have introduced hand hygiene products that clean the skin surface without the need for water and / or drying towels. ...
