Why Hand Sanitizer Manufacturing is a Growing Opportunity

The demand for hand sanitizers skyrocketed during the COVID-19 pandemic and continues to remain high due to heightened hygiene awareness globally. For manufacturers, entrepreneurs, and startups, hand sanitizer production is not only a scalable business but also an essential healthcare solution. However, creating high-quality hand sanitizer requires strict adherence to formulation guidelines, regulatory requirements, and precise manufacturing processes.

This guide provides a detailed overview of the hand sanitizer manufacturing process, key machines, raw materials, and compliance requirements—whether you’re planning to cater to the Indian market, or expand globally.

Types of Hand Sanitizers

1. Alcohol-Based Hand Sanitizers

Contains 60% to 95% alcohol (Ethanol or Isopropyl Alcohol).
Recommended by WHO and CDC for maximum effectiveness.
Regulated as a drug in many countries.

2. Non-Alcohol-Based Hand Sanitizers

Uses antiseptic agents like benzalkonium chloride.
Less effective against certain pathogens.
Often classified as cosmetic products.

Hand Sanitizer Manufacturing Process

1. Formulation

Formulating a high-quality sanitizer requires precision. The WHO and FDA have provided standard formulations to ensure effectiveness:

Formula 1 (Ethanol-based): Glycerin 1.45%, Ethanol 80%, Hydrogen peroxide 0.125%, QS water.
Formula 2 (Isopropanol-based): Glycerin 1.45%, Isopropanol 75%, Hydrogen peroxide 0.125%, QS water.

These formulations must be prepared in an FDA-compliant facility, ensuring the correct alcohol concentration and pH balance using ingredients like Triethanolamine and moisturizers.

2. Mixing of Ingredients

The ingredients must be mixed with care to avoid clumping or aeration:

Water and Carbopol are mixed to form a smooth gel.
Alcohol is added in phases to achieve 70–80% final concentration.
Humectants and preservatives are optionally added based on formulation.
High shear mixers ensure dispersion without trapping air, preventing cloudiness and ensuring consistency.

3. Packaging (Filling, Capping, and Labeling)

Filling:
Automatic filling machines use gravity or piston nozzles to fill bottles with different viscosities. Advanced models ensure accuracy and can handle bulk production.

Capping:
Automatic capping machines with PLC-controlled torque systems tightly seal bottles, allowing seamless transition across bottle shapes and cap types.

Labeling:
Round wrap, double side, and combined labeling machines ensure product details, safety instructions, and branding are applied accurately.

Key Machines Used in Hand Sanitizer Manufacturing

Sanitizer Filling Machine

Handles bottles and jars of various sizes and viscosities.
Offers semi-automatic and fully automatic models.

Digital Filler

Volumetric filling from 10 ml to 1000 liters.

Sealing Machine

Tight closure systems for round, oval, or flat containers.

Capping Machine

Single or multi-head systems with torque adjustments.

Labeling Machine

Supports round wrap, double side, and combined labeling.

Ingredients Used for the Preparation of the Hand Sanitizer:

That is everything there is to it. You only need four ingredients and just a little care about making a hand sanitizer that really is ready for the post-COVID-19 world.

Formula 1: Ethanol (volume %)

Glycerin 1.45%; Ethanol 80%; Hydrogen peroxide 0.125%; QS water

Formula 2: Isopropanol (volume %)

Glycerin 1.45%; Ethanol 75%; Hydrogen peroxide 0.125%; QS water

Including Extra Skin Benefit Ingredients and Fragrance

According to FDA regulations, these are strictly forbidden. Glycerin and fragrance are also found in Purell. Glycerin is a natural and low-cost skin-beneficial ingredient. Fragrances in skin care products are common among consumers. Both ingredients are useless and would lift the price of your hand sanitizer’s raw materials.

Sourcing of Materials, and Notes of Caution

Sterile Water: The best and simple way is to boiling the water. Simply stop heating or boiling water near the flammable, high-proof alcohol.

Ethanol: One important thing to consider is that the ethanol must be denatured, or made to taste bad, in order to avoid consumption.

Testing

If you follow the FD’s hand sanitizer guidelines, you will prevent a lot of problems. There’s no need to test your formula’s bug-killing ability. Hand sanitizers with the above formulas have been shown to effectively kill bugs while remaining healthy for the user. After production, the alcohol level – ethanol or isopropyl alcohol – wants to be check by physical chemistry means such as alcoholmeter or hydrometer.
