While you buy essential oils, there is a need for knowledge about the purity of the oil, its source, and its therapeutic benefits so that you can purchase high-quality essential oils. 

The big secret to a successful purchase is, of course, to due diligence: research and shop only from those credible specialists. 

This ensures you buy the very best essential oils for your skin care, aromatherapy, or homemade cosmetic preparations. Remember that buying pure, top-quality essential oils from a place you can trust to deliver may cost just a bit more, but you're uplifting your game in personal care and noticing a difference in the safety and effectiveness of your home with your cosmetic concoctions.

In this blog, you are going to find all about essential oils for skin care and their uses in beauty and personal care, the purpose that they serve, and guidelines that help in buying correctly and applying them in the right way.

Classification of Essential oils

Essential oils are very complex mixtures, composed of 5000–7000 chemical constituents, mainly monoterpenes and sesquiterpenes but also with an important percentage of aromatic compounds, normally derivatives of phenylpropane and, more rarely, of diterpenes.

Terpenic compounds come from plants, which naturally find their way into molecular mixtures and give out volatile oils. Phenylpropanoids, on the other hand, come from the shikimate pathway, while terpenoids come from the mevalonate and mevalonate-independent pathways.

Here’s the classification based on the functional group:

Functional Group

Extraction of Essential Oils

Volatile oils are generally prepared with a processing method, inclusive of the hydro-distillery process, steam distillation, solvent extraction, and liquid CO2 extraction. The most suitable way of processing would depend on the extraction solvent system adopted, which could cause composition volatility.

Hydrodistillation

  • The procedure begins with placing plant material into a round-bottomed flask. The setup for water distillation is prepared using a modified Clevenger trap.
  • Distillation is then carried out, with the duration varying slightly depending on the condition of the plant material—fresh or dried.
  • Following the distillation process, the essential oil yield is calculated based on the volume of oil extracted compared to the weight of the plant tissue utilized, regardless of whether it is fresh or dry.

Steam Distillation

  • Place either dried or fresh plant material into a round-bottomed flask.
  • Pass steam through the plant matter for a predefined period to gather a condensate mix of water and oil into another flask.
  • Use ethyl ether to extract the volatile oil from the collected condensate, doing this multiple times to fully capture the volatile oil.
  • Add sodium sulfate into the ethyl ether solution to absorb and eliminate any moisture.
  • Apply rotary evaporation to remove the ethyl ether, which will isolate the essential oil.
  • Calculate the yield of essential oil by comparing its volume with the weight of the plant material, taking into account whether it was used fresh or dried.

Solvent Extraction

  • Initially, plant material is either ground or chopped to increase its surface area, making the extraction process more efficient.
  • Next, a suitable solvent, which can dissolve the essential oils but not the majority of other plant substances, is introduced to the plant material.
  • The plant material is then soaked in the solvent, often with agitation, to facilitate the dissolving of the essential oils into the solvent.
  • Next, the mixture is filtered or decanted to separate the liquid extract (which contains the essential oils dissolved in the solvent) from the solid plant residue.
  • Finally, the solvent is removed, typically through evaporation, leaving the essential oils concentrated. This step is often achieved using rotary evaporation or similar evaporation techniques.

Why Use Essential Oils for Cosmetics

Although essential oils are primarily used for their fragrance, essential oils for body care also have a wide range of therapeutic uses that benefit the cosmetics industry when used in cosmetic preparation. The chemistry of healthy essential oils and the location of one or more functional groups within the compound determine their modes of action.

1. Antimicrobial Effect

  • The ability of essential oil constituents to permeate bacterial or fungal cell walls is directly correlated with their solubility in water. 
  • Because Essential oils are soluble in the phospholipid bilayer of cell membranes, they have antimicrobial activity. 
  • Terpenoids are distinguished by their capacity to obstruct the enzymatic processes involved in energy metabolism. 

2. Antiinflammatory Effect

  • Infection, allergic reaction, and immunological response are the main causes of skin inflammation. This results in skin irritation, eczema, dermatitis, blistering, redness, and more.
  • Rosemary (Rosmarinus officinalis Linn.), a member of the Lamiaceae family, is the source of rosemary oil, which is valued for its qualities. Esters, one of its primary ingredients, may help prevent sebum overproduction. 

3. Aromatherapy

  • The potency of Essential oils acts as a pressure point and provides rejuvenation. These essential oils for skin care are used in cosmetics aromatherapy for use in skin, body, face, and hair care products. 
  • They are applied topically or through various small-dosage techniques such as massage, inhalation, or light topical applications.

Market size

According to a report by Fact.MR, the cosmetic oil industry is expected to grow with a CAGR of 5.8% between 2021 and 2031. 

The size of the global market for cosmetic oil according to Precedence Research is estimated to be worth USD 7.51 billion in 2024 and is expected to grow at a compound annual growth rate (CAGR) of 12.3% from 2023 to 2032, reaching approximately USD 19.05 billion.

                                         

Cosmetic Oil Market

In cosmetics, both essential oils and carrier oils like coconut and almond oil are utilized. The market growth of these oils will be supported by their antibacterial, moisturizing, and anti-inflammatory properties, among other qualities that are expected to drive demand in the upcoming years.

How to Select the Right Essential Oils

There are many essential oils for skin care in the market, but to choose wisely, one must consider a few key factors. Their therapeutic properties can be utilized in the preparation of cosmetics. The key factors to consider are:

1. Plant Source

Plant species can differ based on several variables, including harvest time, crop location, parts of the plant (leaves, flowers, seeds, etc.), production and processing methods, and extraction techniques like cold pressing, distillation, critical CO2 extraction, and the use of various solvents. 

Since essential oil is a good source of several bioactive compounds, it is important to understand the state of the raw plant to obtain volatile oil of the highest caliber. 

2. Storage Condition

Essential oils Must be kept out of direct sunlight in a cool environment. This stops the Essential oils from oxidizing and volatilizing. The shelf life of volatile oils is 2-3 years. 

Environmental conditions can alter the chemical composition of essential oils. As a result, the storage condition is given particular attention. A temperature of between 30 and 40 degrees Celsius is ideal for storage. Refrigeration works best when stored carefully.

3. Packaging and Handling

Essential oil may evaporate as a result of breakage or cracks caused by poor handling. When volatile oil is broken down by physical or chemical agents such as heat, light, or oxygen, it can become less effective and produce impurities. 

As a result, packaging needs to be done appropriately. Pure essential oil belongs in an aluminum or glass container. Pure volatile oils should be handled carefully due to their high potency. The humidifier or diffuser should be used when inhaling.
