## IV. Device Description

The proposed unscented menstrual tampons are cylindrical devices designed to absorb menstrual blood during a women's period. They consist of a tampon, including an absorbent pledget ("absorbent core") completely surrounded by an overwrap ("security veil") and a removal string ("withdrawal cord"), and an applicator (except for the digital style). The tampon design is cylindrical, bullet-like shape. The applicator has a smooth, rounded tip for ease of insertion. According to different composition materials and design styles, the unscented menstrual tampons of this submission are divided into 3 categories (Unscented menstrual long applicator tampon, Unscented menstrual Cardboard Applicator Tampon, Unscented menstrual Digital Tampons) and 7 sub-categories (Cotton + cardboard tube, Organic cotton + cardboard tube, Cotton (digital style), Organic cotton(digital style), viscose (digital style), Cotton + plastic tube and Viscose + cardboard tube). For applicator-style tampons, they feature a built-in applicator made of plastic or cardboard that helps the users insert the tampons into the vagina by pushing the tampon out of the applicator. The digital style tampons consist of a plain tampon designed to be inserted manually using the fingers.

The tampons are provided in 4 absorbencies: Light(L) (≤6g), Regular(R) (6-9g), Super (S)(9-12g) and Super Plus (SP)(12-15g). For Cotton + cardboard tube and Organic cotton + cardboard tube, L and SP are applicable for this application. For Cotton (digital style), Organic cotton (digital style) and Viscose (digital style), only L is applicable. For Cotton + plastic tube and Viscose + cardboard tube, all those four absorbencies are applicable for this application.

Each device is individually wrapped and then packaged in sealed multi-unit containers for retail sale. All tampons and applicators are provided non-sterile and for single use only.

Subject Device: Unscented Menstrual Tampon

The subject device and predicate device are similar in the pledget composition and components (tampon and applicator). The subject and predicate device differ in the combination method of pledge and applicator, and available absorbencies.

For Unscented Menstrual Long Applicator Tampon: pledget material was changed from organic cotton to cotton; All the other materials remain the same.

For Unscented Menstrual Cardboard Applicator Tampon: Absorbency options L (Light) and SP (Super Plus) have been added to the Cotton + cardboard tube and Organic cotton + cardboard tube subcategories. Additionally, viscose has been added as a pledget material with all absorbencies (L, R, S, and SP) offered.

For Unscented Menstrual Digital Tampons: Absorbency option L (Light) has been added to the Cotton (digital style), Organic cotton (digital style), and Viscose (digital style) subcategories.

The unscented menstrual tampon (including versions with long applicators, cardboard applicators, and digital tampons) has been updated with new sizes and pledget materials, resulting in slight changes to dimensional and weight specifications compared to the predicate device.

While the method of combining the pledget and applicator differs slightly from that of the predicate device, the materials used remain consistent. The absorbent pledget is made of cotton, organic cotton, or viscose; the overwrap consists of cotton (for cotton type) or organic cotton (for organic cotton type), or Spunbond/thermal-bonded nonwoven fabric/cotton (for Viscose type); the removal string is made of cotton or organic cotton; and the applicator is composed of cardboard or PE.

In summary, the device is substantially equivalent to the predicate devices in terms of features, design, specifications, mode of operation, and intended use. The noted differences do not raise any new safety or effectiveness concerns.

## VII. Substantial Equivalence Discussion:

## Technical Equivalence

Technical equivalence is determined by means of the condition for use, specification, design, deployment method and principle of operation.

Subject devices differ slightly from predicate devices in technical characteristics due to changes in the combinations of pledget and applicators, and the addition of new absorbencies that impact the weight and dimensional specifications. However, these differences do not raise different questions of safety and effectiveness.

## Biocompatibility Assessment

{11}

K253719
Page 8 of 9
Sponsor: Unibeauty (Hubei) Technology Co., Ltd.
Subject Device: Unscented Menstrual Tampon

Biocompatibility studies were performed in accordance with the FDA guidance document "Guidance for industry and Food and Drug Administration Staff - Use of International Standard 1S0 10993-1, "Biological Evaluation of Medical Devices - Part 1: Evaluation and testing within a risk management process" issued on September 8, 2023.

The material of the proposed device is identical to the predicate device (K251033), and K232598 and K252613 (i.e. the absorbent pledget is made of organic cotton, cotton, and viscose, the applicator is made of cardboard and PE, overwrap and removal string are made of cotton, organic cotton and Spunbond/thermal-bonded nonwoven fabric/cotton). Therefore, biocompatibility test data from the predicate device, K232598 and K252613 were leveraged to demonstrate the safety of the material of the proposed device.

## Microbiology Assessment

Per the FDA guidance “Menstrual Tampons and Pads: Information for Premarket Notification Submissions (510(k)s) - Guidance for Industry and FDA Staff”, menstrual tampons should demonstrate that the tampon, in its final manufactured form, does not:

- Enhance the growth of Staphylococcus aureus;
- Increase the production of Toxic Shock Syndrome Toxin-1 (TSST-1);
- Alter the growth of normal vaginal microflora.

The proposed Unscented Menstrual Tampon (Unscented Menstrual Long Applicator Tampon, Unscented Menstrual Cardboard Applicator Tampon, Unscented Menstrual Digital Tampons) are composed of the same raw material as devices cleared in K232598, K252613 and the predicate (K251033). The microbiology test data from the tampons cleared in the predicate device and K232598 were leveraged to demonstrate the microbiological safety of the tampons used with the applicator introduced in the current submission

## Chemical Residue Assessment

Chemical residue assessment of tampons is conducted in accordance with the recommendations outlined in the guidance document “Menstrual Tampons and Pads: Information for Premarket Notification Submissions (510(k)s) - Guidance for Industry and FDA Staff” dated July 2005. The tampons listed as compatible with the subject device applicator are identical to the predicate device (K251033), and K232598. Chemical residue testing of the predicate device and K232598 were leveraged to demonstrate the absence of harmful chemicals in the cotton and viscose versions of this device.

## VIII. Summary of Verification and Validation:

In light of the new absorbency levels introduced, non-clinical performance testing was conducted across all product variants: Unscented Menstrual Long Applicator Tampon, Unscented Menstrual Cardboard Applicator Tampon, and Unscented Menstrual Digital Tampons. Test results confirmed that all devices meet the required performance standards. In accordance with Quality System procedures, all necessary testing was performed to validate

Subject Device: Unscented Menstrual Tampon

the cumulative modifications to the subject devices. A risk analysis was carried out to identify the verification and validation activities required under 21 CFR 820.30.

## IX. Conclusion

The nonclinical tests demonstrate that the subject device, Unscented Menstrual Tampon, is as safe and effective as the legally marketed predicate device (K251033). Therefore, the subject device is substantially equivalent to the predicate device.
