Cosmetics are widely used by both men and women to provide beauty and improve their appearance. Nowadays the demand for herbal cosmetics is increasing because they are harmless. Besides, their side effects are also less because they are prepared by taking extracts of natural herbs and shrubs. It is highly accepted by many people due to its good convenience and affordability with good quality standards. Herbal cosmetics are prepared in many forms, like cold creams, which contain natural extracts of raw herbs like neem, turmeric, extracts of fruits like Bombax ceiba fruit pulp, etc., which contain a variety of ingredients. Cold cream is an emulsion that when applied to the skin produces a cooling effect due to the slow evaporation of water present in the emulsion. These formulations are evaluated on various evaluation parameters like pH, viscosity, irritation, spreadability, microbial growth, thermal stability, uniformity, acid value, saponification value, accelerated stability study, patch test, smear test, post exposure, washability, physical properties. This can be done using, dye test, after feel, in vitro diffusion study etc. The purpose of this review is to compile information on various herbal formulations of cold cream and their evaluation. Herbal cold cream formulations have been studied by many researchers and this information can be used by many researchers to create new herbal cosmetic formulations with new herbs.
Cosmetics are products that are commonly used to beautify the skin and also to purify the skin. The word cosmetic is derived from the Greek word ‘kosmatikos’ which means to adorn. [1] Cold cream is water in oil emulsion. Cold cream provides longer dwell time at the application site compared to other semi-solid dosage forms or formulations. These gives beauty to the skin and the skin does not become too oily. Due to the oil phase it provides softness to the skin. The function of cold cream is to restore moisture in dry skin, it prevents it from getting damaged. The substances come out through the pores and the body also gets coolness. It can be easily washed in water and is also easy to clean. [2] The quality of the finished product was evaluated using various evaluation methods. No change was observed in the physical properties of the prepared cream. The prepared cream showed good stability, spreadability, pH and no evidence of phase separation during the study period of research. Stability parameters like visual appearance, nature, viscosity and The aroma of the prepared cream showed no significant change during the study period of the research. [5] Every plant has medicinal properties, contribution of plants is very essential in the context of today's medical field, and most of the countries were interested in the fact that ancient medicinal plants have discovered the active compound and it is also established for the disease. [3] “Herbal Cosmetics” The demand for herbal medicines is increasing rapidly because they do not have any side effects. Herbal cosmetic means that it is made entirely from herbs and shrubs. Herbs obtained from nature do not affect human skin. [6]
HUMAN ANATOMY OF THE SKIN
skin is the largest organ of the body Surface area and weight. Its surface area is approximately 16000 cm. In adults, skin represents 8% of body weight. It is the outermost layer or tissue of the living body. The skin represents a protective mechanism from the external environment. The skin can produce a beneficial chemical called vitamin D when exposed to sunlight. The skin helps regulate human body temperature and also acts as a sensory organ. [2]
Skin consists of various types of sensory receptors. These receptors are the nerve endings that receive the sensory impulses of touch, pressure, temperature, pain, itch etc. [12]
Epidermis (14):–
The epidermis is a keratinized stratified squamous epithelium that is derived from the ectoderm and forms the outermost layer of the skin. In areas with a heavy protective coat of hair, the epidermis is thinner, in non-hairy skin, such as in mucocutaneous junctions, the epidermis is thicker.
The epidermis consists of two primary cell types -
Dermis [13]: –
It is tough and elastic composed of connective tissue and collagen fibers interlaced with elastic fibers in the matrix. When the skin is overstretched, the elastic fibers break, resulting in the formation of permanent stretch marks. Like - in pregnancy and obesity.
Collagen fibers bind with water and provide the skin with its tensile strength, but as this ability diminishes with age, wrinkles begin to develop. Fibroblasts, macrophages and mast cells are the main cells of the skin. Beneath its deepest layer are areolar tissue and varying amounts of adipose tissue.
The structures in the dermis are: -
Hypodermis (7):-
Also called subcutaneous fasia,
ADVANTAGES (8,9): -
DISADVANTAGES (9):-
Bees wax [10]: - The basic recipe of creams and ointments involves wax and oil in various proportions according to the desired consistency. Beeswax has zero chance of irritation, and the comedogenicity rating is 0-2, meaning that when properly prepared and used in cosmetic formulations, the wax will not cause any problems or clog pores. Will not clog, but brings a lot of positive properties, such as general healing and softening, as an antiseptic, and an emollient for cosmetic products.

Paraben [23]:-
Parabens are one of the most common preservatives used in cosmetic products. They are used in a variety of products including shampoos, lotions, deodorants, scrubs, and eye makeup. Preservatives are added to almost every skin cream or body lotion. Without preservatives, germs will accumulate and spread in the cream, eventually causing skin problems or even dermatitis.
Rose Water [16]: -
Damask rose is botanically known as Rosa damascena Mill. It belongs to the Rosaceae family, a very popular family that contains many ornamental plants. Rose is a valuable and important main ingredient for fragrance and beautification. Phytochemical screening is helpful in the determination of bioactive metabolites that play their role in eliminating free radicals that not only affect the internal organs of the body by producing a variety of diseases but also affect the upper part of the body (skin). Are. We especially do the area which is in direct exposure to sunlight.
HERBAL MATERIALS
Neem [15]: -

Its leaves are used for contraception and abortion. Some people apply neem directly to the skin to treat head lice, skin diseases, wounds, and skin ulcers; as mosquito repellent; And as a skin softener. Neem is also used as a pesticide.
Lemon Oil [17]:-
Lemon essential oil has properties that may benefit human skin during environmental and chronological aging. The cleansing action of lemon essential oil soluble in grape seed oil may have practical applications in aesthetic medicine (a branch of medicine focused on satisfying patients' aesthetic desires and goals) for the treatment of human skin against oxidative damage. Therefore, frequent use of lemon essential oil may contribute to the prevention of lifestyle-related skin diseases by controlling the balance of oxidative stress.
Aloe vera [18]: -
Aloe vera belongs to the Liliaceae family, and is commonly known as quargandal, aloe vera, ghikwar, katarazhai or kumari. It is widely used in medicines. With the improvement in cosmetology it has been proven that aloe vera is a very important ingredient of cosmetics. Cream containing aloe vera is beneficial for skin pimples and acne. Aloe vera gel has proven to be the best remedy for burns and wounds. In fact, the cellular regeneration, anti-bacterial and anti-fungal activities of aloe vera make it useful for skin rashes.

INGREDIENTS AND THAIR USES: -
EVALUATION: -
Pharmaceutical stability studies involve the performance of a drug and its pharmaceutical properties in various forms. Rapid testing and pH-profile kinetics are the most important parts of chemical stability demonstration. pH is an important parameter as far as the effectiveness of the cream is concerned. The pH of human skin usually range from 4.5 to 6.0 and 5.5 is considered to be the average pH of the skin. Therefore, formulations intended for application to the skin should have a pH close to this range.
Mark an area (1sq.cm) on the left hand dorsal surface. The cream was applied to the specified area and time was noted. Irritancy, erythema, edema, was checked if any for regular intervals up to 24 hrs and report.
The spreadability of the formulation shall be determined by an apparatus consisting of a wooden block with a fixed glass slide and a movable glass slide, one end of which is tied to a weight pan rolled on a pulley with the fixed slide. Happens at horizontal level.
Spreadability (S) = M * L / T
Where,
M = weight tied to upper slide
L = length of glass slide
T = time taken to separate the slide completely.
10 g of the substance was dissolved in 50 ml of a precisely weighed 50 ml mixture of equal volumes of alcohol and solvent ether, the flask was connected to a reflux condenser and heated slowly, until the sample was completely dissolved. Don't go. To dissolve, 1 ml phenolphthalein was added and titrated with 0.1N NaOH until it turned yellow. After stirring for 30 seconds a pink color becomes visible.
Acid value = n*5.61/w
Where,
n = the no. of ml of 0.1 N KOH solution.
w = the weight of substance in gram.
These tests were performed to determine microbial contamination of formulations prepared in agar medium. The prepared creams were inoculated onto plates of agar plate medium using the streak plate method and a control without cream was prepared. These plates were placed in the incubator and incubated at 37?C for 24 hours. After the incubation period, the plates were taken out and observed for microbial contamination compared to controls.
