No.087 is a 'low-pH shampoo' and a rinse-off product that cleanses sebum, sweat, and dirt while maintaining the finished product's pH within a mildly acidic range that does not become excessively alkaline on the scalp and hair.
While No.086 Daily Shampoo focuses on the overall balance of cleansing power, lather, and rinsing, No.087 takes the setting, actual measurement, and batch consistency of the finished product pH, as well as its maintenance throughout the shelf life, as its product identity. However, the mere fact that the pH is low does not automatically prove suitability for hypoallergenic or sensitive scalps or hair repair.
Claims regarding scalp and hair cleansing, providing a soft feel and shine, dandruff treatment, and hair loss alleviation within the scope of general cosmetics are separated into a distinct product channel.
Consumers seek mildly acidic shampoos to reduce problems such as excessive scalp tightness or stiff, tangled hair after shampooing. Consumers who repeatedly dye or perm their hair, or who wash their hair daily, place importance on a user experience that provides thorough cleansing without making the hair surface rough.
The factors determining a purchase are as follows.
- Finished product pH consistent with label claims
- Thorough sebum cleansing and rich lather
- Reduces scalp tightness and hair stiffness after cleansing
- Minimizes tangling and combing friction in wet hair
- Rins quickly without leaving residue
- Everyday usability with no excessive lingering scent
- pH, viscosity, and color remain unchanged even after long-term storage
Data on cleansing power, hair texture, and scalp safety must be presented together so that consumers do not compare products based solely on pH levels.
Mildly acidic or pH-balanced shampoos have grown in Asia based on an image of scalp balance and low irritation, whereas in North America and Europe, they are associated with acidic hair care for sensitive scalps, color care, and damaged hair. There is high interest from OEM/ODM buyers because the product concept is easy to understand and can be expanded into various lines, such as daily use, sensitive hair, and colored hair.
The core target audience consists of consumers aged 18 to 50 with normal to dry scalps who shampoo daily, and users who dislike stiffness after washing. Consumers highly sensitive to scalp irritation are classified as No. 088, customers who want a completely fragrance-free option as No. 094, and consumers who prioritize damaged hair repair as No. 092.
The opportunity for K-Beauty does not lie simply in prominently displaying “pH 5.5.” The key is to create a single verifiable product that combines a slightly acidic pH, Korean-style rich lather, clean rinsing, and a soft hair texture .
Essential performance features include maintaining a slightly acidic pH, cleansing daily sebum and dirt, and minimizing scalp tightness and hair friction. It combines anionic and amphoteric surfactants to ensure cleansing power and lather, and can be supported by betaine, glycerin, panthenol, and appropriate conditioning polymers.
pH-adjusting ingredients such as citric acid and lactic acid are a means to achieve the target pH and do not guarantee product efficacy in themselves. Lowering the pH excessively can cause eye and scalp irritation and affect preservative performance, viscosity, and fragrance stability. The recommended development range should be reviewed at approximately pH 4.8 to 5.5 by referring to the design of typical mildly acidic products , but the actual target will be determined through formulation, testing, and claims in the country of sale.
Formula Route | Performance and usability | Buyer's judgment |
|---|---|---|
| A. Low-pH Balanced Sulfate-Free | Slightly acidic pH, ample foam, low tightness | Global Hero Recommendation |
| B. Amino Acid Mild Low-pH | Gentle cleaning and low degreasing | Sensitive/Premium derivative |
| C. Acidic Color/Damage Care | Mildly acidic cleansing + enhanced conditioning | Specializing in dyed and damaged hair |
The first option is a Low-pH Balanced Sulfate-Free Shampoo . It ensures sufficient cleansing power through a surfactant combination and incorporates an excessive amount of conditioning ingredients to prevent fine hair from being flattened or residue from remaining on the scalp.
Vanicream also presents itself as pH-balanced and sulfate-free, but it completes its product logic by simplifying not only the pH but also the structures of fragrances, extracts, and cleansers. Vanicream Official Product Information
Major safety risks include batch deviations where pH falls outside the target range, scalp and eye irritation caused by surfactants and fragrances, and reduced shelf life due to pH changes. We do not claim "non-irritating," "scalp barrier restoration," or "treatment for sensitive scalps" solely on the grounds that the product is mildly acidic.
To indicate “pH-balanced” or a specific pH value, data for the finished product is required not only immediately after production but also throughout the shelf life. Since pH can vary due to variations in raw material manufacturing, interactions with flavorings and extracts, and the container after filling, it is managed according to batch-based shipping specifications.
market | Key Launch Points | Validation to be required in the RFQ |
|---|---|---|
| korea | Review of general shampoo range, pH, low irritation, and hair loss-related expressions | pH, retention, and scalp/hair usability per batch |
| EU/EEA | EU Responsible Person, CPSR/PIF, CPNP and Fragrance Review | pH stability, safety assessment, claim data |
| USA | MoCRA separates general cosmetics and dandruff treatment OTC pathways | Proven safety, U.S. label, basis for pH claims |
| japan | Compliance with Cosmetic Standards, separation of medicinal expressions | Prescription suitability, pH/stability, Japanese claims |
Essential validation includes pH immediately after manufacturing and after high, room, and low temperatures, as well as viscosity, color, fragrance, phase separation, preservation power, and microbial limits. Performance is evaluated based on sebum cleansing, lathering and rinsing, scalp tightness, wet hair combing, and shine and heaviness after drying.
The U.S. FDA distinguishes between general cleansing shampoos and dandruff treatment shampoos, explaining that the latter are subject to both cosmetic and pharmaceutical requirements.
For the global Hero SKU, the 300–350mL lock-up pump bottle is suitable. It offers a good balance of personal use and premium pricing, and is easy to pair with conditioners in the same line. The 500mL size will be used in family and value channels, while the 700–1,000mL refills will be expanded after repeat purchases are confirmed.
Although the container material does not directly determine the pH of the finished product, changes in color and scent due to long-term contact, as well as the suitability of the sealing and pump spring, must be verified. Transparent bottles can convey a slightly acidic, clean image, but color changes are easily visible, which may limit the use of light-sensitive ingredients.
The target shelf life is to be 30 to 36 months unopened, but it is determined based on data regarding pH, preservation, stability, and container suitability. There must be no pH shift, viscosity reduction, or leakage after high-temperature processing, and no turbidity, precipitation, or pump discharge failure after low-temperature processing.
The recommended application is Accessible pH-Balanced Scalp Care, which enhances pH management and hair texture compared to regular daily shampoos . Rather than relying on the single phrase “pH 5.5,” it presents batch-based care, low-tightness cleansing, and reduced hair friction as its values.
The recommended retail price range is as follows.
- 300~350mL Hero SKU: US$16~24
- 500mL Family Pump: US$22~32
- Amino acid-based premium type: US$22~34
While it is possible to set a slightly higher price than a standard daily shampoo, it is difficult to induce repurchase based solely on the pH level if there is no difference in actual user experience. The combination of the finished product and the conditioner from the same line enhances the persuasiveness of the price.

K-Beauty should combine Sebamed's clear pH, Vanicream's simplicity, and Redken's hair sensation, but without exaggerating damage repair, and focus on balanced cleansing for normal to dry scalps and soft hair texture .
While mildly acidic shampoos are highly accessible for domestic OEM/ODM manufacturing, simply verifying the pH of the initial sample provided by the manufacturer is insufficient. It is necessary to verify their experience with pH management, viscosity, and preservation systems capable of maintaining the same range even after raw material batching, mass production, and long-term storage.
Manufacturing route | Suitable business conditions | Key RFQ Checklist |
|---|---|---|
| Large-scale comprehensive ODM | Multinational Launch, Testing, and Regulatory Support | pH standards, long-term stability, hair evaluation, export documents |
| Mid-sized ODM specializing in hair care | Sensory Adjustment · Medium MOQ | Simultaneous stabilization of cleaning, foaming, tangling, pH, and viscosity |

The business potential is high. Mild acidity is easy for global buyers to understand and can be expanded as a common technological asset across daily, sensitive, color, and damaged skin lines. However, credibility is compromised if all scalp problems are explained solely by pH.
The initial Hero was developed as a mildly acidic shampoo for normal to dry scalps, while the sensitive scalp No. 088 and fragrance-free No. 094 are operated as separate SKUs with stricter standards for fragrance, ingredients, and safety.
Global Core: A+
The mildly acidic and pH-balanced concept is easy to understand across countries and hair types and can be extended to daily cleansing and color and sensitive lines.
OEM/ODM Priority: A+
This is a key item well-suited to leverage the strengths of Korean manufacturers in surfactant, pH, foam, and hair sensation design. pH consistency is critical after mass production.
NoChemiLife Hero: Candidate
. A product is suitable as a Hero if it ensures low fragrance, a controlled ingredient structure, a slightly acidic pH, and the scalp safety of the finished product. Low irritation is not determined solely by pH.
