FIELD OF THE INVENTION
Generally, the present disclosure relates to shampoo compositions. Particularly, it relates to waterless (dry) shampoo compositions. More particularly, it relates to alcohol-free waterless 5 (dry) shampoo compositions.
BACKGROUND OF THE INVENTION
Shampooing forms an essential part of hair care in today’s society. Shampoos can broadly be classified into two types: wet shampoos and waterless (dry) shampoos.
While wet shampoos are quite efficient, they require the use of water, which is an extremely 10 precious resource. Further, wet shampoo compositions generally contain alcohol, which can cause hair dryness. Moreover, wet shampoos are often required to be used in conjunction with conditioners, which give the hair a shiny look and help in maintaining the pH balance of the hair.
Waterless shampoos (also known as dry shampoos), on the other hand, are a great way to 15 reduce the use of water in hair maintenance. Since no water is required, waterless (dry) shampoos can be used even by people living in areas where water is scarce, including campers, backpackers, defence personnel in remote areas, and the like.
However, existing dry shampoos are largely inefficient in removing odour, dirt, sweat, and oil. Further, unlike wet shampoos, they leave behind residue that is difficult to remove. Due 20 to these reasons, dry shampoos have not become popular with consumers.
There is therefore, a need in the art for a waterless (dry) shampoo composition that does not contain alcohol.
There is therefore, a need in the art for a waterless (dry) shampoo composition that cleans the hair completely without leaving behind any undesirable residue. 25
There is therefore, a need in the art for a waterless (dry) shampoo composition that can also condition the hair, thereby giving the hair a shiny look, in addition to maintaining the pH of the hair.
SUMMARY OF THE INVENTION
In order to overcome the above mentioned drawbacks, alcohol-free waterless (dry) shampoo 30 compositions are disclosed, said alcohol-free waterless (dry) shampoo compositions consisting of 85% to 95% of water as a solvent, 5% to 7% of a principle surfactant, 0.75% to 1.25% of a secondary surfactant, 0.065% to 0.075% of a first preservative, 0.065% to 0.075% of a second preservative, 0.065% to 0.075% of a third preservative, 1.71% to 2.26% of a moisturizer, 0.045% to 0.055% of a modifier and 0.055 to 0.065% of a fragrance. 35

For the other examples, the viscosity was tested using the below described procedure:
A quantity of oil (200C + 0.10) was placed in a filling tube and transferred to a capillary tube by gentle suction, taking care to prevent bubble formation in the liquid by keeping the air 5 vent tube closed. The meniscus of the column of liquid in the capillary tube was adjusted to the level of the top graduation line. Both the vent and the capillary tubes were opened in order to permit the liquid to flow into the reservoir against atmospheric pressure. The time, in seconds, for the liquid to flow from the upper mark to the lower mark in the capillary tube was recorded. 10
The viscometer constant, k, was calculated from the equation:
k = v/dt
where,
v is the known viscosity of the liquid in centipoise,
d is the specific gravity of the liquid tested at 200C, and 15
t is the time in seconds for the liquid to pass from the upper mark to the lower mark.

The pH was determined potentiometrically by means of a glass electrode and a suitable pH meter (digital). After setting the pH meter at 25ºC, the pH meter was standardized using standard buffer solutions of pH value 6.0 and 7.0. The pH of the shampoo was then measured. 5
The microbial limits were determined using the below mentioned protocol.
Pre-treatment of the sample:
10 g of the preparation under examination was suspended in buffered sodium chloride- peptone solution (pH 7.0) or any other suitable medium shown to have no antimicrobial activity. The volume was adjusted to 100 ml with the same. A suitable surface active agent 10 such as 0.1% w/v solution of Polysorbate 80 was added (where required) to assist with the suspension of poorly wettable substances.
Inactivation of antimicrobial activity: For test specimens known to contain antimicrobial substances, a corresponding inactivating agent was used to neutralize the antimicrobial activity. The inactivating agent (Polysorbate 80) was added to the chosen diluent preferably 15 before sterilization.
All the necessary items required for the testing were kept under a laminar air flow (LAF).
The pre-sterilized petri dish was labelled with glass marker, to show the media name (soyabean casein digest agar (SCDA) for bacterial count or Sabouraud Dextrose agar (SDA) for fungal count), the name of the product, the batch number and the date of analysis. 20
Each of 1 ml of pre-treated sample was carefully pipetted onto previously labelled petri dish in duplicate, said petri dish being maintained under a laminar air flow.
10
Positive control: Known volume of cells (10-10 cells) of E.coli/ S.aureus was added in SCDA plate and allowed to solidify for 30 minutes s. Likewise, known volume of cells of Candida albicans was added in SDA plate allowed to solidify for 30 minutes.
Negative Control: SCDA/ SDA media was poured in pre-sterilized and labeled plates and allow to solidify. 5
The plates were incubated at respective temperatures (SCDA – 350C-370C/ SDA 200C – 250C) for 120 hours (5 days).
The incubated plates were monitored every 24 hours.
Calculation:
Average No. of colonies X Dilution factor 10 CFU / g = ----------------------------------------------------------- Weight of sample
It was ensured that the negative control did not show any growth at the end of the incubation period.
Pathogens test: The pathogens mainly comprise of E.coli, Salmonella, S.aureus and 15 P.aeruginosa.
Sample preparation: 10 gm sample was aseptically transferred into sterile 90 ml SCDM broth.
The media was labelled with the media name, the product batch number and the incubation date and incubated at 300C – 350C for 18- 24 hours. After the incubation, if the media was 20 clear, it was concluded that pathogens are absent. If turbidity was observed, then specific testing of pathogens was carried out as described below:
E.coli:
Primary test: 0.1ml of enrichment media was transferred into 10ml of MacConkey’s broth containing inverted Durham’s tube and incubated at 300C – 370C for 24 hours to 48 hours. 25
The tube was labelled to show enrichment transfers (SCDM to MacConkey broth), sample number and the date of enrichment and incubated at 300C – 370C for 24 hours.
After incubation, if Durhams tube showed gas and if a colour change to yellow occurred, then a loopful of the same was streaked on MacConkey agar plate and incubated for 24 – 72 hours at 300C – 370C. If no change was observed, then the testing was stopped. 30
Upon incubation, the plate was observed for typical culture characteristics of E.coli. If typical characteristics were found, then secondary test was conducted.
If no typical characteristics were found, the result was recorded as ‘Absent’ for E.coli.
11
Secondary test (Indole test):
0.5 ml kovac’s reagent was added in to pre- incubated 5 ml peptone water (1%).
After shaking, it was allowed to stand for 1 minute, the formation of a pink coloured ring was interpreted as a positive result. 5
The presence of acid and gas and of indole in the secondary test indicates the presence of E.coli.
Cultural characteristics of E.coli in MacConkey agar is as follows:
MacConkey agar plate
Brick red, colonies may have surrounding zone of precipitated bile.
Salmonella: 10
0.1 ml of primary enrichment from SCDM was aseptically transferred into 10 ml of sterilized Selenite-F-Broth or 10 ml of Tetrathionate Brilliant green Broth tube.
The tube was labelled to show the enrichment transfers (SCDM to SFB/ SCDM to TTBGB), product identification and date of Enrichment and incubated at 350C – 370C for 24 hours.
After the incubation period, if the SFB tube showed turbidity and the TTBGB tubes showed 15 disappearance of green colour with white precipitate, then loopful of enrichment was picked up and streaked on surface of pre-incubated Bismuth sulfite agar (BSA)/ Brilliant Green Agar (BGA) Media plates/ Xylose lysine Deoxycholate agar/ Deoxycholate agar plate. The plate was labelled to show enrichment transfers, (SFB to BGA/ SFB to BSA/ TTBGB to BSA) product identification and date of streaking. 20
Upon incubation, if the plate showed typical cultural characteristics of Salmonella, biochemical identification test was conducted to confirm the same.
Secondary test (TSI test):
Any colonies showing the typical characteristics were sub-cultured in triple sugar iron agar by first inoculating the surface of the slope with inoculating needle and then making a stab 25 cultures with the same inoculating needle.
These two tubes were incubated at 350C – 370C for 18 - 24 hours.
After incubation, yellow butt (acidic) with pink slant (alkaline), with or without concomitant blackening of butt from H2S production in TSI tubes indicated the presence of Salmonella. The cultural characteristics of Salmonella in media plates is as follows: 30
