3.What are the primary ingredients used in shampoo manufacturing?

Shampoo manufacturing is a complex process in which various ingredients are carefully mixed together to create an effective product which can cleanse scalp with nourishing and conditioning catering specific hair concern. Let’s look into each ingredient that you find in typical shampoo.

Deionized water

Deionized Water

Most important ingredient in shampoo manufacturing is water as it is 70-80% of total shampoo and act as transport medium for blending and mixing of other additives. But the water used in shampoo manufacturing is not an ordinary tap water, it is deionized water.

Deionized water, is the water from which all mineral like calcium, sodium and magnesium, and other impurities are removed through deionization process. Why it is important to use deionize water? Because it free from all minerals, increasing its compatibility with other ingredients and all impurities are removed which reduce chances of microbial contamination and enhances its performance.

Surfactant

Surfactant in Shampoo Manufacturing

Surfactant are major cleaning agent in shampoo. It is added to aid foaming in shampoo manufacturing resulting in washing of dirt, oil and residue of hair care product on scalp. There are two different types of surfactant used in shampoo manufacturing

• Primary surfactant
• Secondary surfactant

Let’s discuss in detail function of each surfactant and how they are different from each other?

Primary surfactant

Primary Surfactant- Picture Courtesy: Pharma Excipients

Primary surfactant is main cleaning agent and they are mainly responsible for removing dirt, sebum and debris from scalp. They exert best foaming property and easily rinse off from hair without leaving residue. They easily mix with oil so remove dirt that are not washable with water.

Most commonly used primary surfactant are sodium lauryl sulphate (SLS) and sodium laureth sulphate(SLES) due to their lathering ability and, easy mixing of oil in water.

Seconadary surfactant

Secondary Surfactant –Picture Courtesy: Formula Botanica

Secondary surfactant is also known as co-surfactant. They are added to enhance overall performance of shampoo and other properties like mildness, conditioning, nourishing content and viscosity depending on customer demand. These effects are restored by combined effect of both or by only secondary surfactant properties.

Some of secondary surfactant used depending on manufacturer requirement are, cocamidopropyl betaine(CAPB) used for milder preparation and gives conditioning effects to hair, cocamidopropylamine oxide(CAO) added for stabilizing and enhancing foaming property, and alkyl polyglycoside are used as eco-friendly choice because it is easily biodegradable, and still gives good foaming and cleaning effect.

Thickeners

Thickener – Picture Courtesy: Cosmetic Ingredient

Thickeners are added in shampoo for various reason, although thickeners do not impart any role in cleaning and foaming properties of shampoo. Thickeners are added to enhance product stability hence providing even distribution of other ingredient.

Thickeners also facilitate in maintaining viscosity of shampoo. If shampoo is too thin it will run down from your hair and if it is too thick it will not easily spread or penetrate in hair. Appropriate thickness also gives product luxurious feel and enjoyable to use for consumer.

Shampoo manufacturing with desired viscosity provide consumer better overall experience and effectiveness. There are so many options available for thickeners used in shampoo manufacturing like xanthan gum, guar gum, hydroxyethyl cellulose, carbomer and many more depending on manufacturer requirement.

Conditioning agent

We all know that main function of shampoo is to clean and remove dirt oil. But due to evolving market trend and consumer demand of shampoo with other additional benefit like conditioning, nourishing and repairing of hair are gaining popularity.

Incorporating conditioning agent in shampoo enhances overall performance by providing protection, nourishment and give smooth texture to hair. It makes hair silky and detangle which are easily manageable and give smooth look to hairs.

There is some common conditioning agent which you find in most of commercial shampoo manufacturing are silicones which include dimethicone, natural oils like coconut oil and argan oil and fatty alcohols like stearyl and cetyl alcohol.

Preservatives

Preservative

Preservatives are crucial component in shampoo manufacturing. Preservative are added in formulation to extend shelf life and prevent contamination from microbial growth like mould and fungi. It is also needed to make sure the product is equally effective and safe to use till mentioned expiry.

Few examples that are frequently use are potassium sorbate and sodium benzoate etc. You have to keep in mind few factors while selecting preservative like pH level, composition of product and desired shelf life.

Fragrance and colorant

In second phase, ingredients are mixed in large mixing tank in a specific manner. Mixing and blending is critical step in shampoo manufacturing because it ensures that you will get perfect consistency in every batch.

This purpose is served by using different agitators and high-shear mixer which ensure thoroughly mixing of ingredients. The duration and speed of mixing is also play important role in achieving uniformity in mixture.

Heating and cooling

Heating and Cooling

This process is incorporated because certain ingredient required specific temperature to dissolve or activate. Heating assist dissolution of certain ingredients like thickeners and it also facilitate emulsification.

After that temperature is cooled down to introduce heat-sensitive ingredients like fragrance, preservative and coloring agent without affecting its performance.

Homogenization

Homogenization

Finally, mixture is passed through homogenization process to ensure uniformity throughout the mixtures. This purpose is best served by homogenizer. In this step mixture is mixed at high speed which lead to reduced particle size creating consistent and smooth texture of shampoo.

Homogenization is most important step in shampoo manufacturing for achieving desired texture and all ingredients are evenly distributed throughout the mixture.

Quality checking
