The present disclosure relates generally to compositions and methods for reducing odor, specifically for neutralizing malodor adhering to skin or hair.
Malodor may be caused by a variety of factors. For example, malodor causing agents and everyday odors may adhere to the skin, hair, and/or body from exposure to the environment (e.g., mildew, smoke, or sewage) and some working conditions (e.g., chemicals). Personal hygiene and other lifestyle factors may also lead to malodor.
In particular, for those in the medical field, malodor is often caused by exposure to formaldehyde or other chemicals and is very difficult to counteract. For example, medical school and laboratory employees may be exposed to embalming fluid, which typically contains a mixture of formaldehyde, glutaraldehyde, methanol, and other solvents. Many medical school and laboratory employees complain that even with wearing one or two pairs of gloves, their hands can smell of formaldehyde or other chemicals afterward which can make food taste worse and affect sleep and social life.
Accordingly, there is a need in the art for improved compositions that can reduce odors, and in particular, can reduce malodors adhered to the skin, hair, and/or body.
In one aspect, the present disclosure provides an odor reducing composition comprising:
In another aspect, the present disclosure provides an odor reducing composition comprising:
In another aspect, the present disclosure provides a method for reducing malodor on skin or hair, the method comprising providing an odor reducing composition as described herein and applying the composition to the skin or hair.

In another aspect, the present disclosure provides a method for reducing malodor on skin or hair, the method comprising providing an odor reducing product as described herein and applying the product to the skin or hair.

An odor reducing composition, particularly useful as a hand wash was prepared by first preparing a surfactant composition. The components of the surfactant composition are recited in Table 1.
The components listed in Table 1 were mixed together to provide the surfactant composition. The odor reducing composition was prepared by adding 25 wt. % of the surfactant composition to 70.82 wt. % water with 0.76 wt. % soya morpholinium ethosulfate, 0.04 wt. % sodium alginate, and other additives. The full formulation of the odor reducing composition is described in Table 2.
The odor reducing composition with both soya morpholinium ethosulfate and sodium alginate (SME+ALG), as described in Example 1, was then tested for its odor reducing properties. To do so, 1 gram of a concentrated malodor solution standard was sprayed onto a porous substrate. Then, 0.4 grams of a 10% solution of the odor reducing composition of Example 1 was sprayed onto the substrate and evaluated by a 3 person sensory panel. The 10% dilution of the odor reducing composition simulates a concentration that would be present during handwashing. The panel then ranked the malodor on a scale of 0-9 (9=very strong malodor, 5=moderate malodor, and 0=no malodor). As a comparison, two comparison composition were also prepared. The first comparative composition was made according to the same composition as reported in Table 2, but without sodium alginate and will be referred to as the SME (soya morpholinium ethosulfate) formulation. The second comparative composition was made according to the same composition as reported in Table 2, but without soya morpholinium ethosulfate and will be referred to as the ALG (sodium alginate) formulation. The results of the odor reducing tests against three malodors (BO, smoke, and bathroom) for the three formulations (SME, ALG, SME+ALG) are reported in
