Embodiment 1

[0187] Example 1 - Deodorizing Mixture (Spray)

[0188] A deodorizing mixture was prepared by mixing all of the ingredients described below (% values ​​are weight percent on the total weight of the composition).

[0189] -0.30% Cosmocil CQ (20% concentration)

[0190] -0.15% Sinodur

[0191] -2.00% Colalipid C

[0192] -0.80% Nipaguard PO-05

[0193] -0.50% lactic acid

[0194] -Trace sodium hydroxide (enough to adjust pH to 4.0)

[0195] -96.25% ethanol

[0196] The mixture of clear alcohol solutions will be filled into sprayers for later application to sanitary napkins.

[0197] In an alternative embodiment, the deodorant composition has less diluent (ethanol) but the same relative amounts of other components, effectively providing a concentrate. Concentrates can be concentrated 5 to 25 times (ie have 5 to 25 times less diluent). While such concentrated deodorant compositions must be applied to articles with greater accuracy, overall processing efficiency can be im...

Embodiment 2

[0198] Example 2 - Deodorizing mixture (dipping agent)

[0199] A deodorizing mixture was prepared by mixing all of the following ingredients:

[0200] -3g Cosmocil CQ (20% strength)

[0201] -1.5g Sinodur

[0202] -20g Colalipid C

[0203] -8g Nipaguard PO-05

[0204] -5g lactic acid

[0205] -Trace sodium hydroxide (enough to adjust pH to 4.0)

[0206] -962.5g deionized water

[0207] The mixture, which will be a clear aqueous solution, is filled into a dip coater for later application to sanitary napkins.

[0208] Likewise, in some alternative embodiments, the deodorant composition has less diluent (water) but the same relative amounts of the other listed components, effectively providing a concentrate. The composition may, for example, be concentrated 10 to 20 times (ie it contains 10 or 20 times less diluent).

Embodiment 3

[0209] The preparation of embodiment 3-sanitary napkin

[0210] Sanitary napkins are prepared as a multilayer structure having:

[0211] Layer 1 - A comfort layer consisting of a non-absorbent porous film (or woven synthetic material) that separates the user from the underlying layer and allows air to circulate.

[0212] Layer 2 - Acquisition layer consisting of absorbent paper which holds the lower layer in place.

[0213] Layer 3 - Absorbent core / layer composed of superabsorbent polymer and cellulose fibers configured to receive and retain secreted body fluids.

[0214] Layer 4 - The non-absorbent film, which is positioned below the absorbent layer to contain bodily fluids.

[0215] Layer 5 - Release paper, which can be removed from the bottom of the non-absorbent film to expose the adhesive that bonds the sanitary napkin on the inside of the underwear item.

[0216] A quantity of the spray of Example 1 (based on the weight of the sanitary napkin) was sprayed onto the und...

Abstract

The present invention relates to an absorbent article, such as a sanitary towel, impregnated or coated with a deodorising composition comprising a buffering component, a deodorising agent, and an antimicrobial agent. Such deodorising compositions help to reduce or eliminate odours emanating from the bodily fluids absorbed into the article during use.

Description

technical field [0001] The present invention relates to absorbent articles, such as sanitary napkins, diapers or incontinence pads, which are configured to absorb and retain secreted or excreted body fluids. More particularly, the present invention relates to absorbent articles comprising deodorant compositions for reducing or eliminating odors from secreted or excreted body fluids absorbed into said articles during use. The invention also relates to the deodorant composition itself, the method of making the deodorant composition, the method of applying the deodorant composition to an article, and the use of the deodorant composition in or on an article for reducing or eliminating odors caused by bodily fluids. The use of the odor caused by the secretion or excretion. Background technique [0002] Articles designed to absorb and retain body fluids, such as sanitary napkins, diapers or incontinence pads, are widely used. In all of these articles, however, there is a need to...
