Disodium Cocoamphodiacetate (CAS 68650-39-5) is a widely-used amphoteric surfactant derived from coconut-based raw materials. As a yellowish clear liquid, this raw material balances gentle cleansing, rich foaming and thickening functions. It has become a popular choice for formulators who develop mild-type personal-care goods. Apart from traditional wash-off cosmetic products, it also shows great application potential in contact lens care solutions. This article introduces its core features, main benefits, typical application areas, formulation advice and product storage notes for global cosmetic and optical-care manufacturers and buyers.
I. Key Physical-Chemical Specifications of Disodium Cocoamphodiacetate
This product is supplied as yellowish clear liquid for industrial production. Its solid content stays between 38.0 % and 40.0 %. Under 25 °C condition with 10 % water solution, its pH value ranges from 8.0 to 10.0. Salt content is controlled at ≤9.5 %, and viscosity is no more than 5000 mPa·s. Its Gardner color number is ≤3. These stable indexes make it easy to mix with most cosmetic and optical-care raw materials in mass production.
All above figures stand for typical test data. They are not fixed legal product specifications. Buyers should refer to the official Certificate of Analysis for exact batch values before bulk purchase. The standard package is 200 kg per drum for international trade.
II. Core Advantages: Mildness, Foaming Power and Good Compatibility
Low skin and mucosa irritation ranks as its most outstanding strength. It fits formulas made for sensitive-skin users and babies. Even with strong cleaning ability, it will not remove too much natural lipid from human skin or eye mucosa surface.
Second, it delivers high-quality foam. It creates rich, smooth and stable lather in rinse-off products. It can work both as primary surfactant or auxiliary foaming booster. Besides foam performance, it shows satisfying thickening ability to help formulators adjust product viscosity easily.
Another important advantage is excellent ingredient compatibility. It can mix well with anionic, cationic and non-ionic surfactants. Formulators can combine it with many other cleaning materials to lower overall irritation and improve final product user experience. Its low-irritation feature makes it acceptable for formulas that touch human eye tissue.
III. Wide Application Fields in Personal-Care & Optical-Care Products
Thanks to its balanced performance, sodium cocoamphodiacetate fits many rinse-off personal-care items, and it can be adopted for contact lens care solutions.
Facial cleanser is one major usage. It supports gentle face-washing formulas that do not cause tight-dry feeling after cleaning. For body wash, it generates comfortable foam for daily shower products. It is especially well-known for baby tearless shampoo. Its low-irritation property reduces eye-sting risk for kids.
It is also widely added into mild daily-use shampoo for sensitive-scalp consumers. In addition, it works nicely for shaving products. It creates smooth slip during shaving and reduces skin friction damage. In all these finished goods, it may act either as main surfactant or secondary functional component.
For contact lens care solutions, this amphoteric surfactant serves as gentle cleansing agent. It can effectively remove protein deposits, grease and cosmetic residues left on contact lens surfaces. Meanwhile, it brings minimal stimulation to eye mucosa. It helps clean lenses without hurting eyes, and supports comfortable wearing experience after lens cleaning.
IV. Practical Formula Guidelines for Formulators
The common addition level for disodium cocoamphodiacetate falls in the range of 1.0 %-20.0 % in total formula weight for personal-care products. For contact lens care solution systems, formulators need to adopt much lower dosage and complete strict biocompatibility and eye-irritation tests.
When mixed with other surfactants, it can greatly cut the irritation of some high-irritation anionic surfactants. Formulation teams can test different mixing ratios to balance foaming effect, skin feeling and production cost. For baby-care, sensitive-skin products and eye-contact products such as lens care liquid, formulators are suggested to select proper lower-to-medium dosage and complete full safety tests before mass production.
V. Storage, Handling and Shelf-Life Suggestions
Correct storage conditions protect product quality during transportation and warehouse keeping. Keep disodium cocoamphodiacetate in cool, dry, ventilated and lightless places. Avoid direct heat and strong sunlight exposure. Keep containers tightly closed after partial use.
Under proper storage environment, its shelf life reaches 12 months from production date. End users are advised to check appearance and key parameters before using stored material. Once past shelf-life date, do not apply it to cosmetic or optical-care production. For overseas importers, 200 kg/drum packing is ready for container shipment.
To sum up, disodium cocoamphodiacetate CAS 68650-39-5 provides a reliable solution for global cosmetic and optical-care brands chasing mild, high-foam formulas. It combines low irritation, stable foaming, thickening function and broad raw-material compatibility. It will keep playing an important role in today’s sulfate-free gentle-cleaning consumer-product market, covering body care as well as eye-care related products.
