Embodiment 1

[0070] Example 1-Screening of Silicone Surfactants

[0071] Example 1 shows various silicone surfactants and their ability to generate stable foam. The following foam height screening procedure was used to evaluate the foaming ability of silicone surfactants. Preparation of raw material solution: Prepare a solution consisting of 75.6% ethanol SDA 40B (190 proof, 99.5% active) and 24.4% water.

[0072] Sample preparation: Weigh approximately 0.35 g of silicone surfactant and 9.65 g of raw material solution into a 20 mL vial. The solution is then mixed until a homogeneous solution is obtained.

[0073] Foam height screening: In order to screen the foam height of each solution, put a small part (~1mL) of the prepared solution into a 2oz bottle with a spray foam pump head, rinse the surroundings, and discard. After the bottle was rinsed, the residual content of the sample formulation was then transferred to a 2oz bottle with an air spray foam pump head. Start filling the foaming pump...

[0078] Example 2-Foam height compared to silicone surfactant concentration

[0079] Example 2 measured the effect of polydimethylsiloxane surfactant concentration on foam height. For this example, the following test was used to measure the foam height:

[0080] Preparation of raw material solution: Prepare the solution with the following formula:

[0081] Raw material solution

[0082] Add the following amount to a 60 mL tank. The silicone surfactants used are Silsurf DI-1010, Silsoft 810 and Silsoft 870.

[0083] Sample preparation: in a 60mL tank,

[0084] sample

[0085] Foam height screening: In order to screen the foam height of each solution, use a small part (~1mL) of the prepared solution to rinse a 2oz bottle with a spray foam pump head and discard it. After rinsing the bottle, the residual content of the sample formulation was then transferred to a 2oz bottle with a spray foam pump head. Start filling the foaming pump head until liquid or foam is generated through th...

Abstract

Foaming alcohol compositions with selected dimethicone surfactants are disclosed. The dimethicone surfactants are PEG-8 to PEG-12 linear dimethicone surfactants and in particular PEG-10 linear dimethicone surfactant. The compositions are useful as antimicrobial products and in particular handcare or skincare products.

Description

Technical field [0001] The invention discloses a foaming alcohol composition containing a selected dimethicone surfactant. The polydimethylsiloxane surfactant is a PEG-8 to PEG-12 linear polydimethylsiloxane surfactant, especially a PEG-10 linear polydimethylsiloxane surfactant. The composition can be used as an antimicrobial product, especially a hand or skin care product. Background technique [0002] Alcoholic compositions are desirable hand and skin care products. They are effective against a wide range of microorganisms such as Gram-positive and Gram-negative bacteria and fungi. And they can kill microorganisms faster than other antimicrobial products. Alcohol antimicrobial products are available as water thin liquids, gels, emulsions and aerosol foams. Commercially available aerosol alcohol foam, such as QUIKCARE commercially available from Ecolab Inc. (St. Paul, Minnesota) TM Rely on propellant to produce foam. Because the surface tension of alcohol is too low for mo...
