HiSiaddi is an innovative foreign trade service provider driven by both technology commercialization and export services. It has established a service system defined as "1+2+3+4=1" and can supply raw materials of Cocamidopropyl Betaine from multiple well-known original manufacturers. As a tech-enabled foreign trade service provider, HiSiaddi repeatedly collaborates with factories on technology commercialization and accurately captures market demands, enabling it to propose formulation optimization schemes and application improvement suggestions for Cocamidopropyl Betaine. Below is a consultation case of formulation optimization for Cocamidopropyl Betaine by HiSiaddi.

The cooperating client is LUXE CARE, an Italian luxury skincare brand specializing in premium facial cleansers, fragrance body washes and repair shampoos. Its products are sold in high-end beauty retail stores and star hotels across multiple European countries, strictly complying with EU cosmetic regulations, IFRA Version 51 and sensitive skin raw material standards. Cocamidopropyl Betaine (CAB-35) acts as the core amphoteric surfactant across all its cleansing products. The brand has long sourced mid-to-high-end domestic CAB-35 raw materials. Recently, consecutive batches of finished products presented issues including turbid systems, thin foam that dissipates easily, delamination during low-temperature storage, and slight stinging skin sensation with certain batches, forcing production line slowdowns and delaying new product launches. The client’s internal formulation team failed to resolve these recurring problems after repeated adjustments to ingredient ratios and production parameters, so they commissioned HiSiaddi to conduct fault diagnosis, technical optimization and rectification implementation.
Combining raw material testing, formulation review and production condition simulation, HiSiaddi’s technical team identified four core root causes:
1.
Excessive raw material impurities triggering skin irritation Sampling inspection revealed excessive free amine content in the CAB-35 batches. Amine byproducts remaining from production constitute the primary cause of mild stinging sensation for sensitive skin users, conflicting with the brand’s low-irritation positioning.
2.
3.
Imbalanced compounding system leading to turbidity and poor foam performance The client’s formulation mixes CAB-35 with anionic surfactants and plant oil solubilizers. Electrolyte content within the raw material disrupts micelle structures after blending, reducing system light transmittance and creating hazy turbidity. Meanwhile, high proportions of oily skincare ingredients further suppress foaming, resulting in low foam volume and poor stability.
4.
5.
Insufficient low-temperature stability causing delamination during storage and transportation European winter temperatures can drop to -5°C; this grade of CAB-35 exhibits weak cold resistance, with reduced solubility of components at low temperatures leading to obvious delamination that damages product appearance and user experience.
6.
7.
Improper production temperature control and feeding procedures exacerbating quality fluctuations The client heats the mixture above 65°C during stirring, causing minor molecular decomposition of CAB-35. Unreasonable feeding sequences create localized high salt concentrations when high-concentration surfactants are mixed directly, worsening system instability.
8.
HiSiaddi developed rectification plans covering four dimensions: raw material upgrading, formulation adjustment, standardized production processes and application testing, and tracked full implementation to completely eliminate all technical issues.
Coordinate cooperative factories to optimize purification processes for supplied CAB-35 by adopting multi-stage vacuum deamination technology to strictly control free amine content below 0.3%. Fine-tune salt proportions to lower overall electrolyte levels. Attach third-party test reports to every delivery batch and establish raw material incoming sampling inspection standards to prevent unqualified raw materials from entering production lines.
Slightly increase the dosage of CAB-35 to balance the defoaming effect of oily ingredients; add a small amount of nonionic surfactants to boost foam density and durability. Precisely adjust system pH to the range of 5.5–6.5, avoiding the low pH range prone to turbidity for the raw material. Optimize the ratio of oil solubilizers to enhance compatibility of all components and restore transparent finished product appearance. Fine-tune system salt content based on the salt thickening curve to prevent micelle damage caused by excessive electrolytes.
Specify production temperature limits: cap mixing and stirring temperature at 50°C to eliminate high-temperature-induced raw material decomposition and preserve inherent surfactant performance. Revise feeding sequence: mix pure water and anionic surfactants evenly first, then slowly add CAB-35 under low-speed stirring, followed by plant extracts and fragrances to avoid flocculation from localized high concentrations. Extend low-speed stirring duration to guarantee uniform mixing and reduce quality discrepancies between batches.
Cold resistance test: Store rectified finished products at -5°C for 30 days with repeated cycling tests; the system remains uniform without delamination or precipitates. Accelerated aging test: No obvious changes to odor, transparency or foam performance after 90 days of room-temperature storage. Complete progressive verification from lab trials to pilot production and full-line mass production; compile bilingual Chinese-English standard operating procedures for the client’s formulation and production teams to establish long-term control specifications.
· Improved safety compliance: Raw material free amine indicators remain stably within standards; finished products pass sensitive skin tests with irritation fully compliant with European high-end skincare benchmarks.
· Restored product quality: Finished products become clear and transparent with dense, long-lasting foam, and all sensory indicators return to design specifications.
· Normalized production: Production lines resume full-capacity operation with zero defective products, and no delamination occurs during low-temperature storage or cross-border transportation.
· Deepened long-term cooperation: The client adopted the raw material acceptance standards and production specifications formulated by HiSiaddi, designating HiSiaddi as a fixed raw material supplier and continuously seeking technical support for subsequent new product formulation R&D.
High-end skincare products impose far stricter requirements on surfactant purity, compound compatibility, temperature stability and safety than ordinary daily chemical products. The root cause of this batch of failures was a combination of defective raw material quality plus improper formulation and production processes. Leveraging comprehensive capabilities in raw material control, formulation technology and production process guidance, HiSiaddi implemented full-chain rectification from source to end-use, rapidly resolving production crises while helping the client improve its quality control system, fully meeting the stringent technical requirements of overseas mid-to-high-end brands.
