Description

DETAILED DESCRIPTION OF INVENTION

[0011] The present invention describes a reconstitutable sanitiser formulation in anhydrous powder form. Said powder form is easy to transport and is devoid of any alcoholic microbicide. The sanitiser of the invention is further provided with moisturizers to maintain the moisture of the skin.

[0012] For the purpose of this invention, the terms “a”, “an” and “the” encompass both singular and plural reference.

[0013] For the purpose of this invention, the term “microbe” and its variations thereof encompass both bacteria, protozoa and viruses which may be lingering on the surface of skin. The term, further, encompasses, pathogenic and non-pathogenic microorganisms and viruses.

[0014] In an embodiment, the reconstitutable sanitiser formulation of the invention may comprises of a antimicrobicidal agent a humectant a conditioning agent/Film former/Antistatic Agent a sequestering agent perfume, colour and Extract

[0015] Preferably, the antimicrobicidal agent is a Quaternary ammonium compounds, selected from the group consisting of mixture of alkyl dimethyl benzylammonium chlorides, generally grouped as benzalkonium chloride, dimethyl dodecyl ammonium chloride or bromide, cetyltrimethylammonium bromide, cetylpyridinium chloride etc or lactic Acid/natural actives. Therefore, the invention uses Cationic antimicrobial agent to achieve almost complete sanitisation of hands, killing up to 99.9% of microbial load. Further, as Cationic antimicrobial agent does not evaporate like alcohol, hence, the sanitiser of the invention provides a long-lasting microbicidal protection of 2-6 hrs with conditioning property

[0016] The humectant as used herein is selected from triethylene glycol, tripropylene glycol, propylene glycol, glycerine, sorbitol, hexylene and butylene glycol, urea, sucrose, collagen or milk protein as skin conditioning agent. The humectant retains the moisture of the skin, thereby preventing drying of the skin.

[0017] The conditioning agent/Film former/Antistatic Agent is selected from agent known in the prior arts. Preferably, the agent is selected from Polyquaternium compound, such as, Polyquaternium-1, Polyquaternium-2, Polyquaternium-4, Polyquaternium-5, Polyquaternium-6, Polyquaternium-7, Polyquaternium-8, Polyquaternium-9, Polyquaternium-10, Polyquaternium-11, Polyquaternium-12, Polyquaternium-13, Polyquaternium-14, Polyquaternium-15, Polyquaternium-16, Polyquaternium-17, Polyquaternium-18, Polyquaternium-19, Polyquaternium-20, Polyquaternium-22, Polyquaternium-24, Polyquaternium-27, Polyquaternium-28, Polyquaternium-29, Polyquaternium-30, Polyquaternium-31, Polyquaternium-32, Polyquaternium-33, Polyquaternium-34, Polyquaternium-35, Polyquaternium-36, Polyquaternium-37, Polyquaternium-39, Polyquaternium-42, Polyquaternium-43, Polyquaternium-44, Polyquaternium-45, Polyquaternium-46, Polyquaternium-47, Acrylamidopropyltrimonium Chloride/Acrylamide Copolymer, Gum or combinations thereof.

[0018] The conditioning agent locks the moisture of skin, thereby preventing the dryness and/or itchiness of skin caused due to alcohols present in sanitisers currently available in market.

[0019] The sanitiser further comprises of suitable sequestering agent, selected from EDTA and it salts thereof, citric acid, cyclodextrin, Sodium Gluconate, etc and the like.

[0020] Depending upon the end use for which the reconstitutable sanitiser of this invention is intended, it may further contain components such as perfumes, gums, flavouring agents, colouring agents, and inorganic or organic salts.

[0021] The sanitiser of the invention is in form of a powder which needs to be reconstituted before the use. As the sanitiser is formulated in powder form, it is easy and economical to transport as there is no spilling hazard involved.

[0022] Further, since the powder could be reconstituted, the sanitiser can be commercialised as such, in pouch form, this reduces the usage of plastic containers which are required for containing the liquid. This reduces plastic usage, as a single container can be used multiple times by emptying the pouch containing powder sanitizer composition into the container. The container may be an empty bottle, an empty bottle with a Flip top cap, or an empty pump spray bottle.

[0023] In an embodiment, when the user intends to use the sanitiser, following procedure needs to be followed:

[0024] Step a: Emptying the sachet containing 0.8 gm to 3 gm of reconstitutable powder adding sufficient quantity of 80 to 100 ml potable water;

[0025] Step b: adding the reconstitutable powder in the Potable water, and

[0026] Step c: shaking the mixture vigorously.

[0027] Selection/screening of correct conditioning/film forming/antistatic agent which get easily soluble within few mins to an hour and which is less hygroscopic or completely non hygroscopic in nature.

[0028] Select antimicrobial agent which is compatible with the other ingredients and soluble easily.

[0029] Screening of correct other ingredients which are compatible with each other.

[0030] In an advantageous embodiment, the sanitiser of the invention provides a long-lasting protection against microbes. As, the active Cationic antimicrobial ingredient of current invention stays on the skin surface for longer period of time as compared to alcohol.

[0031] In another advantageous embodiment, the sanitiser of the invention provides reduction of up to 99.9% microbial load for a 2-6 hrs.

[0032] In another advantageous embodiment, the presence of humectants and conditioning agents maintains the moisture in the skin thereby ensuring minimal damage to skin surface.
