Abstract
Topical applications of the drugs have an advantage of delivering the drug directly to the site of action and acting for a
longer period of time. Skin is one of the most widespread and readily accessible organs on the human body for topical
administration and is the main route of topical drug delivery system. The main aim of this project was to formulate a
natural and safe herbal skin toner which has calming, soothing, and astringent, effect on the face and skin to reduce the
facial irritancy and enhance the beauty and can be used in day today busy schedule. The extracts used are from the
ingredients which are easily available, economical and has nutritional value from topical point of view. Toner has gained
the popularity as it can be used daily and helps in restoring the skin texture hence the purpose of the study was aimed
for the similar formulation.
Keywords: Aloe Vera (Aloe barbadensis miller); Cucumber (Cucumissativus); Honey; Rose Water
1. Introduction
1.1. Herbal Cosmetics
The herbal cosmetics are the preparations containing phytochemical from a variety of botanical sources, which
influences the functions of skin and also provide nutrients necessary for the healthy skin and body [1]. The natural herbs
and their products or extract when used for their aromatic value in cosmetic preparation are called as herbal cosmetics
[2]. There has been a common belief that the chemical-based cosmetics may be harmful to the skin and turned in
increased awareness among consumers for herbal products which triggered the demand for natural products and
natural extracts in cosmetics preparations [3].
1.2. Gel
A gel is a solid or semisolid system of at least two constituents, consisting of a condensed mass enclosing and
interpenetrated by a liquid. The characteristic of gel and jelly is the presence of some form of cutaneous structure, which
provides solid-like properties [4] Gels and jellies are composed of small number of solids dispersed in relatively large
amount of liquid, yet they possess more solid-like than liquid-like character.
1.3. Advantages of gel
Gels forms can be used to achieve optimal cutaneous and percutaneous drug delivery.
They are non-invasive and have more patient compliance.
They can avoid gastrointestinal drug absorption difficulties caused by gastrointestinal pH.
World Journal of Advanced Research and Reviews, 2021, 11(01), 138–145
139
Gels are having property to avoid enzymatic activity and drug interaction with food, drinks and other products
in diet.
They can avoid the first pass effect, that is, the initial pass of drug substance through the human body.
They avoid systemic and portal circulation following gastrointestinal absorption.
Gels are not deactivated by liver enzymes because the liver is bypassed.
Gels are applied over skin for slow and prolonged absorption.
They have localized effect with minimum side effects compared to the other forms [5].
1.4. Toners
Toner removes any last traces of dirt; grime and impurities stuck in your skin pores after you wash your face. When
added to your daily skincare routine and used regularly, it can have major positive impact on the appearance and
tightness of your pores (aging skin).[6]
1.5. Effects of a toner on skin
Earlier the skin toner was a typical product used as a second cleansing agent for removing residual makeup after regular
facial cleansing or used for removing excess sebum secreted from facial skin and to prepare the skin before nourishing
treatment. Toners may be categorized into alcohol-based or non-alcohol-based toners for various skin types such as
oily skin, sensitive skin, or combination skin. Nowadays, the diversity and prevalence of the products cause skin toners
to be utilized more as cosmceutical products with several purposes; for example, rehydrating skin, balancing skin pH,
tightening skin pores, relieving irritation, and also antisepsis [6].
2. Material and methods
Fresh cucumbers, aloe Vera and roses were obtained from the local market of Pune. Carbopol 934 and methanol were
obtained from SD Fine Chemical Ltd. Mumbai. All other chemicals used were of analytical grade.
2.1. Drug information
2.1.1. Cucumber
Cucumber, Cucumissativus (family- Cucurbitaceous) are obtained throughout India. The silica in cucumber is an
essential component of healthy connective tissue, which includes muscles, tendons, ligaments, cartilage, and bone.
Cucumber juice is often recommended as a source of silica to improve the complexion and health of the skin, plus
cucumber's high-water content makes it naturally hydrating, a must for glowing skin [7].
The flesh of cucumber is primarily composed of water but also contains ascorbic acid (vitamin C) and caffeic acid, both
of which help soothe skin irritations and reduce swelling.
Medicinal Importance
Cucumber has loads of water content to keep skin hydrated. The cooling properties along with antioxidants and silica
present in cucumbers help rejuvenate the skin. The flesh of the cucumber is mostly water, but also contains ascorbic
acid (vitamin C) and caffeic acid, both of which help soothe skin irritations and reduce swelling and these acids prevent
water retention.
2.1.2. Aloe Vera
The botanical name of Aloe Vera is Aloe barbadensis miller. It belongs to Asphodelaceae (Liliaceae) family, and is a
shrubby or arborescent, perennial, xerophytic, succulent, pea- green color plant [8].
Active components with its properties
Aloe Vera contains 75 potentially active constituents: vitamins, enzymes, minerals, sugars, lignin, saponins, salicylic
acids and amino acids [8-11].
Vitamins
It contains vitamins A (beta-carotene), C and E, which are antioxidants. It also contains vitamin B12, folic acid, and
choline.
World Journal of Advanced Research and Reviews, 2021, 11(01), 138–145
140
Enzymes
It contains 8 enzymes like aliases, alkaline phosphatase, amylase, bradykinase, carboxypeptidase, catalase, cellulase,
lipase, and peroxidase. Bradykinase helps to reduce excessive inflammation when applied to the skin topically.
Minerals
The calcium, chromium, copper, selenium, magnesium, manganese, potassium, sodium and zinc are essential for the
proper functioning of various enzyme systems in different metabolic pathways and few are antioxidants.
2.1.3. Rose water
Rose water is extracted by distilling rose petals with steam. Rose water is fragrant, and it’s sometimes used as a mild
natural fragrance as an alternative to chemical-filled perfumes. It’s been used traditionally in both beauty products and
food and drink products. It also comes with plenty of potential health benefits. It has been used for thousands of years,
including in the Middle Ages [13].
Medicinal importance
Anti-Inflammatory Action
Moisturizing and Anti-Aging Agent
Cosmetic & Skin Protection Application
Astringent effect on skin pores
Skin whitening Agent
2.1.4. Honey
Honey is a mixture of carbohydrates, proteins, amino acids, vitamins, minerals, antioxidants and other compounds. It
consists number of enzymes, including invertase, glucose oxidase, catalase, and acid phosphorylase. Honey also contains
eighteen free amino acids, in which the most abundant is proline.
The main group of antioxidants in honey are the Flavonoids, of which, pinocembrin is unique to honey and bee propolis.
Naturally darker honey has greater antioxidant properties in it. Acetic, butanoic, formic, citric, succinic, lactic, malic,
pyroglutamic, gluconic acids, and a number of aromatic acids are found in honey. Bee’s honey is almost free of
cholesterols. It also contains trace amounts of the vitamins B2, B4, B5, B6, B11 and vitamin C. Also, Minerals like calcium,
iron, zinc, potassium, phosphorous, magnesium, selenium, chromium and manganese are found in honey [14].
2.2. Preparation of extracts
2.2.1. Aloe vera gel
Steps for Preparation of aloe vera gel:[15]
The central parenchymatous pulp was scooped out with a spatula from the Aloe leaves and the pulp was washed
repeatedly with water and finally treated with 0.1 N sodium hydroxide (NaOH) to increase the pH of juice and
to avoid to acidity in preparation.
The treated pulp was placed in a blender to obtain the juice.
The obtained juice was subjected to vacuum filtration to get clear liquid.
To the clear liquid so obtained, Carbopol 934 was added and dispersed uniformly ensuring no lumps.
The prepared aloe vera gel was weighed and stored in air tight containers in a dark room to prevent photo-
oxidation to prepare formulation.
2.2.2. Cucumber extract
Preparation of Extract [16, 17]
For isolating the extract from cucumber, cucumbers were properly peeled, washed and chopped finely.
The chopped material was then crushed in a grinder and the slurry obtained was passed through the muslin
cloth in order to obtain the cucumber juice.
The juice was then lyophilized at a temperature of -70 °C so that a freeze-dried extract in the solid form can be
obtained.
The extracts can be stored by keeping in refrigerator till use.

Follow it up with a serum or moisturizer.
3.3. Evaluation of gel toner
Preliminary evaluation of formulation was carried out as follows.
3.3.1. pH
The pH meter was calibrated and measured the pH by placing in the beaker containing 20mg of the gel. [19]
3.3.2. Spreadability Test
500mg of the gel was sandwiched between 2 slides. A weight of 100gm was placed on upper slide. The weight was
removed and extra gel was scrapped off. The lower slide was fixed on board of apparatus and upper slide was fixed with
non-flexible string on which 20g load was applied. Time taken by upper slide to slip off was noted down and the spread
ability was tested.[20]
3.3.3. Homogeneity
This test for the gel was done by physical touch with hands.
3.3.4. Appearance
The appearance of prepared gel was found by observing its colour, opacity, etc physical parameters.
3.3.5. After Feel
After applying the herbal gel toner on skin, the properties like emollient nature, slipperiness and the amount of gel left
after application was noted.
3.3.6. Smear Type
The test was conducted after the application of gel on the skin the smear formed was oily or aqueous in nature.
3.3.7. Removal
The removal of the gel applied on skin was done by washing under tap water with minimal force to remove the gel.
3.3.8. Patch Test
About 1-3gm of material to be tested was placed on a piece of fabric or funnel and applied to the sensitive part of the
skin e.g., skin behind ears. The cosmetic to be tested was applied to an area of 1sq.m. of the skin. Control patches were
also applied. The site of patch is inspected after 24 hrs. As there was no reaction the test was repeated three times. As
no reaction was observed on third application, the person may be taken as not hypersensitive.[21]
3.3.9. Irritancy Test
The gel was applied on left hand dorsal side surface of 1sq.cm and observed in equal intervals up to 24hrs for irritancy,
redness and oedema. [22]
3.3.10. Accelerated Stability Studies
Accelerated stability studies were performed on all the formulations by maintaining at room temperature for 20 days
with constant time interval. During the stability studies the parameters like homogeneity, viscosity, physical changes,
pH and type of smear were studied.[23]
3.3.11. Extrudability
A simple method was adopted for this study. The formulation was filled in the collapsible tubes after the gel was set in
the container. The extrudability of formulation was determined in terms of weight in grams required to extrude a 0.5
cm of ribbon of gel in 10 second.[24]

5. Results and Discussion
This herbal formulation especially in a gel form was prepared by using the ingredients which are available in day-to-
day life also, which were very natural and harmless. The main purpose behind formulating it in the form of gel was its
easiness in applicability and Spreadability. Also, formulating a toner was intended so as to check the effectiveness of
such natural substances like cucumber and aloe vera on the skin and to check whether they are able to produce the

cleansing effect in a gel form. By seeing the observations and the results, it proved to be satisfactory. The formulation
showed on application had very soothing and cleansing and most importantly toning effect on the skin. It gave the
feeling of tightened skin.
5.1. Stability studies
Accelerated stability studies were performed on the formulation by maintaining at room temperature for 60 days with
constant time interval. During the stability studies the parameters like homogeneity, viscosity, physical changes, pH and
type of smear were studied and were found to be satisfactory as well.
6. Conclusion
From the above studies of the formulation, it is clear that the herbal gel toner prepared is effective for the smoothening,
calming, astringent, and rejuvenating effect on the skin. It is non irritable and can be used on daily bases for enhancing
the natural beauty of human skin. The formulation was also found to possess significant antioxidant activity which may
contribute to its sunscreen activity. In addition to the above-mentioned parameters the gel toner was found to have
good homogeneity along with good spreadability and pH in the range of skin. Thus, the gel form of herbal toner can be
used topically for improving the health and rejuvenation of the dried and pale skin. It was also found that the ingredients
like cucumber and Aloevera gave the best results for hydration and acne problems.
