Yes, we will refer you to the fastest available clinical testing center in use.

You may use the images provided provided after the test.

This is possible if the formulation of the bulk sample is the same as the one that will be produced.

Through our MOUs, with multiple in use clinical testing centers, we offer the lowest price with discounts for a single test as well.

Through MOUs with the largest number of domestic and foreign in use clinical testing centers, we provide a bulk comparative estimate, and our consultants, who are professional researchers, design and propose the most suitable test for your company in consideration of cost, duration, and credibility.

Yes, we provide reports in English (except for reports for Korean Ministry of Food and Drug Safety).

Yes, you can. We make it easier for brands to access markets all around the world.

On average, you can expect to save 20-30%.

The process will proceed as follows.

1. Submit a clinical testing request

2. Propose a quote and decide on which clinical testing to proceed

3. Sign the contract and proceed to clinical testing

4. Receive the final report

Clinical testing occurs after the formulation is finalized, typically before product launch, using a sample. Costs range from 000 to 000, and the duration varies depending on the test item, but generally spans at least one month. CTKCLIP uses AI to design tests and collaborates with specialized partners to deliver final reports up to 2 weeks faster than other companies.

Have you ever seen the phrase "Up to 000% improvement after 2 weeks of use" or "Hypoallergenic tested" on product labels or advertisements? These claims are based on the results of clinical testing. For such claims to be used on product detail pages or in advertisements, clinical testing must be completed.

It refers to tests conducted on humans to confirm the effectiveness and safety of cosmetics. Examples include "dermatologically tested" for hypoallergenic properties, "non-comedogenic" to check for pore-clogging potential, and so on.

An OTC (Over The Counter) Drug Monograph is a set of regulations that serve as a benchmark for determining the safety and effectiveness of over-the-counter (OTC) products. It includes detailed requirements such as active ingredients, labeling, and warning statements for each product category. Continuously updated, these regulations ensure that OTC products adhering to the monograph are considered safe and effective in the market.

Have you ever seen a Drug Facts label on products sold in the United States?

In the U.S., OTC products are required to list active ingredients, usage instructions, and related information on a 'Drug Facts' label so that customers can easily understand them.

Adhering to the Drug Facts labeling regulations, which serve as the verification standard for OTC products, is very important. CTKCLIP guides you through this labeling process during product development to ensure it is not difficult.

[Label Information]

• Active Ingredients and Inactive Ingredients.
• Purpose: Indicate each active ingredient included in the product and its purpose.
• Use: Indicate the approved uses of the product; for OTC cosmetics, only uses with medicinal relevance are listed.
• Warning: There is no specific order for listing warnings, but it is recommended to list them in order of importance.
• Directions: Indicate information such as age restrictions, usage methods, and recommended amounts.
• Other Information: Indicate additional important information or content mentioned in the OTC monograph.

This is the stage where we verify if the product maintains stability and efficacy in the production environment.

Process Validation

Verifies if the API components (Active Pharmaceutical Ingredient) in the product are produced as intended. (API assay Test / Long Term ST/CT)

In this stage, various tests related to product efficacy and stability will be conducted. The SPF and expiration date will be determined through these tests.

FDA SPF Value Testing

In addition to standard safety tests required for cosmetics or OTC products, sunscreens will be tested to determine SPF Value, which can begin once final approval is given for the product sample.

Method VALIDATION

To conduct Actives Testing, you must work with an accredited lab to ensure that there is a proven method for detecting an active ingredient and its concentration. This process is known as Method Validation, and it usually takes about 4-8 weeks to complete.

PET (Preservative Efficacy Test)

PET is a laboratory test used to assess the effectiveness of preservatives in cosmetic and personal care products in preventing microbial contamination per USP guidelines.

Accelerated ST/CT

6 months of completed accelerated study = 2 years of expiration date.

The OTC production process consists of the following stages:

Formulation and Container Development -> Pre-Production Testing -> Production Preparation -> Production Execution -> Post-Production Testing -> Shipping.

Step 01: Formulation and Container Development

This stage involves developing the formulation and container. Based on development inquiries, formulation samples are created, and specifications for the formulation and container are finalized.

Step 02: Pre-Production Testing

Various tests related to the product's efficacy and stability are conducted. This includes confirming SPF (Sun Protection Factor), expiration date (EXP), and more.

Step 03: Production Preparation

This stage involves preparing raw materials and other necessary components for production. The production quantity needs to be confirmed as the process is based on the required quantity.

Step 04: Production Execution

Actual manufacturing is carried out according to the production plan. The production period may vary depending on the quantity, and batch testing and quality inspections are conducted.

Step 05: Post-Production Testing

This stage verifies that the product maintains stability and efficacy in the production environment.

Step 06: Shipping

After production and testing are completed, the product is shipped to the designated location. The transportation period may vary depending on the destination and shipping conditions.

Development costs vary depending on the type of product and the testing requirements.
