Applications of Ultrasonic Technology in Cosmetics Manufacturing

In cosmetics manufacturing, combining ingredients in the same vessel does not necessarily mean the system has achieved the desired structure. For creams, emulsion serums, or formulations containing ingredients that need to be dispersed, product developers must also consider the state of each phase, the distribution of droplets or particle agglomerates, viscosity, temperature, and overall system stability.

In suitable systems, ultrasonic energy is transmitted through a sonotrode into the liquid medium. Acoustic cavitation and localized mechanical effects can be utilized to support processes such as emulsification, deagglomeration, and dispersion.

Actual performance depends on the formulation, equipment, amplitude, processing time, volume, temperature, vessel geometry, and how the material moves through the ultrasonic treatment zone. Therefore, VietSonic structures the content in this section around the following sequence:

PROCESS STAGES

Where Can Ultrasound Be Investigated in the Process?

Emulsification

For systems containing both oil and water phases, ultrasound can be investigated to support the formation or refinement of dispersed droplets when the formulation and interfacial stabilization system are appropriate.

Dispersion

The mechanical effects of ultrasound may help break down agglomerates and improve the distribution of certain types of particles in a liquid medium.

Homogenization

The technology can be arranged in combination with mixing, pre-emulsification, or recirculation to move material through a high-energy treatment zone.

Dissolution Support

In suitable systems, ultrasound may support mass transfer and increase contact between the material and solvent during processing.

Extraction

Ultrasound is also studied for processes that transfer components from botanical or other starting materials into a solvent medium.

Process Development

Amplitude, time, volume, temperature, and sonotrode configuration should be recorded to evaluate reproducibility and scale-up.

KNOWLEDGE LIBRARY

A Structured Article Library Instead of a Broad Claim About “Ultrasonic Technology”

From the Commercial Services page, VietSonic will develop multiple groups of in-depth articles to explain specific issues in cream and serum manufacturing.

Fundamentals

Acoustic cavitation, emulsification, dissolution, dispersion, homogenization, and key terms that need to be distinguished.

Cream Manufacturing Technology

Emulsification, oil–water ratio, viscosity, structure formation, stability, and the position of the ultrasonic step.

Serum Manufacturing Technology

Distinguishing solution serums, gels, emulsions, and particle-containing systems before selecting a technology.

Ingredients

Analyzing the physical state of each ingredient and the process questions that should be considered during treatment.

Measurement & Verification

Controls, size, viscosity, temperature, stability, and the data that should be collected.

Equipment & Scale

From laboratory probes to vessels, mixing, cooling, and recirculation systems when scaling up production.

PILLAR 02 · MAI BRAND

VietSonic distributes Mai cosmetics

Alongside the development of ultrasonic technology applications, VietSonic is expanding its commercial activities into the cosmetics sector through the distribution of the Mai brand.

Mai is being developed around two main product lines: Mai Cream and Mai Serum. These two product groups will also provide a practical context for VietSonic to gradually develop a knowledge system covering formulations, emulsification, dispersion, ingredients, and verification methods in cosmetics manufacturing.

What VietSonic aims to build goes beyond product introductions; it also includes a content system that helps readers better understand the technical processes behind cosmetic products.

MAI

CREAM · SERUM

Cosmetics distributed by VietSonic

TWO PRODUCT LINES

Mai Cream and Mai Serum

MAI · CREAM

Mai Cream

Mai Cream is a cream-format product line under the Mai brand, distributed by VietSonic.

According to the currently available basic ingredient list, the cream formulation includes information on ingredients such as Tranexamic Acid, Alpha Arbutin, Vitamin B3, Panthenol B5, Aloe Vera extract, Chamomile extract, Vitamin E, an ingredient referred to as Nano White Turmeric, and other base ingredients.

The currently available product documentation also describes the use of ultrasonic homogenization to support dispersion and emulsification. In-depth articles on VietSonic will continue to analyze each process step, mechanism, and evaluation method rather than inferring results from the name of the technology alone.

MAI · SERUM

Mai Serum

Mai Serum is a serum product line under the Mai brand, distributed by VietSonic.

Serums can exist in several physical forms, including solutions, gels, emulsions, or dispersed systems. Therefore, when investigating ultrasonic technology applications, the formulation structure and processing objective should be identified before selecting a treatment method.

Upcoming articles in this section will explain when a serum requires emulsification, when conventional mixing may already be sufficient, and when ultrasonic technology is worth investigating.

TECHNOLOGY × PRODUCT

The Connection Between the Ultrasonic Technology Platform of VietSonic and Mai Cosmetics

From Technology Expertise…

VietSonic develops high-power ultrasonic systems for a wide range of liquid-processing applications. In cosmetics, this platform opens research directions in emulsification, dispersion, homogenization, and extraction.

→

…to Deeper Product Understanding

Mai Cream and Mai Serum provide a practical context for building a content system that explains technology, ingredients, and evaluation methods in a more accessible way.

Technology only has value when its results can be verified.

Therefore, VietSonic will clearly distinguish between process objectives, research findings, and data actually measured on a specific formulation. The use of ultrasound does not automatically prove that a product has reached nanoscale dimensions, is more stable, or delivers better skincare performance.

SKINCARE CREAM

Technology Topics to Be Developed for Cream Systems

Creams are typically multi-component systems and may contain an oil phase, a water phase, structuring agents, emulsifiers, and various other ingredient groups.

Why do oil–water systems need stabilization?
What role does pre-emulsification play before ultrasonic treatment?
How does viscosity affect ultrasonic processing?
Should ultrasound be applied before or after thickening?
How can batches with and without ultrasound be compared fairly?
Is the absence of phase separation enough to conclude that a cream is stable?

MAI CREAM

A Practical Application Context

The currently available information on Mai Cream enables VietSonic to progressively develop in-depth articles on ingredients, emulsification, dispersion, and process verification.

Conclusions about stability, droplet size, or finished-product performance should only be published when supported by corresponding data.

SERUM

Serums Should Be Classified Before Discussing Equipment

MAI SERUM

A Different Product Line, a Different Process Question

Mai Serum is distributed by VietSonic alongside Mai Cream. Technical content for serum will be developed separately rather than copying cream processes or ingredients into serum applications.

The term “serum” alone does not indicate whether a product requires emulsification or only dissolution. The physical system of the formulation must be identified first.

Solution
Gel
Emulsion
Dispersed System

Only then can the appropriate process objective be determined: dissolution, dispersion, emulsification, or control of an already formed structure.

VERIFICATION

From Descriptive Claims to Measurable Data

Objective	Possible Evaluation Methods	Do Not Conclude Based Only On
Emulsification	Droplet size and distribution, phase-separation monitoring, and appropriate observation methods	A perception that the cream feels smooth
Dispersion	Particle/agglomerate distribution, uniformity, and sedimentation tendency	Visual inspection alone
Viscosity	Measurement under controlled and repeatable conditions	A subjective sense that the product is thick or thin
Stability	Monitoring over time under appropriate evaluation conditions	A freshly produced sample showing no phase separation
Nanoscale Size	Size and distribution measurements appropriate to the object being measured	The machine name or the use of ultrasound

UNDERSTANDING THE TECHNOLOGY CORRECTLY

Three Principles VietSonic uses when developing content

Do Not Equate Ultrasound with Nano

Using ultrasound is not sufficient to call a system “nano.” The result must specify what was measured and the evaluation method used.

Always Account for Heat

Ultrasonic processing can change the sample temperature. Therefore, the thermal history and cooling strategy should be monitored.

Technology Does Not Replace Formulation Design

The formulation, emulsification system, structure, and preservation strategy still need to be properly designed. Equipment is only one part of the process.

FREQUENTLY ASKED QUESTIONS

Information About the Commercial Services of VietSonic

Do the Commercial Services of VietSonic only include ultrasonic equipment?

No. In addition to researching and providing ultrasonic technology solutions, VietSonic also distributes the Mai cosmetics brand, with two product lines: Mai Cream and Mai Serum.

What product lines does Mai currently offer?

The two main product lines introduced in this section are Mai Cream and Mai Serum.

Are all Mai products manufactured using ultrasound?

That should not be assumed. Technology-related content must be based on the documentation for each product and each process step. Current documentation for Mai Cream describes the use of ultrasonic homogenization to support dispersion and emulsification; for Mai Serum, the technology-related content needs to be determined separately based on the actual formulation and process.

Does using ultrasound mean a cosmetic product is nano?

No. Droplet or particle size must be measured using an appropriate method. The use of ultrasonic equipment does not by itself prove that a system has reached nanoscale dimensions.

Why does VietSonic develop many focused articles on this topic?

Emulsification, dispersion, dissolution, viscosity, particle size, ingredients, and scale-up are different issues. Separating them into focused articles helps explain each topic accurately and avoids overly broad conclusions about the technology.

VietSonic × MAI

From a Technology Foundation to a New Commercial Direction

Commercial Services mark a new area of expansion for VietSonic: continuing to build on its ultrasonic technology capabilities while bringing that knowledge closer to the cosmetics sector and real-world products.

Through Mai, VietSonic currently distributes two product lines: Cream and Serum. Alongside its commercial activities, the website article system will progressively explain the technical issues behind cosmetics manufacturing—from ingredients, emulsification, and dispersion to methods for verifying a process change.

The goal is for every technology-focused piece of content to answer three questions: where the technology acts, what needs to be controlled, and what must be measured to understand the result.
