Bulk 3-Aminopropane Sulfonic Acid Supplier (CAS 3687-18-1) – ≥98.0% Purity, EU Supply
3-Aminopropane Sulfonic Acid is a white crystalline ingredient supplied for cosmetic and personal-care formulation development. It is commercially relevant for evaluation as a hydrotrope or secondary cleansing aid in aqueous systems, with additional formulation precedent in leave-on skin-care complexes containing calcium hydroxymethionine.
Who This Product Is For
| Customer type | Typical requirement |
|---|---|
| Skin-care manufacturers | Development of water-based serums, gels, gel-creams and emulsions |
| Personal-care manufacturers | Screening as a hydrotrope or secondary cleansing ingredient |
| Formulation and R&D teams | Solubility, compatibility, stability and performance evaluation |
| Ingredient distributors | Supply of a defined-purity specialty cosmetic ingredient |

Technical & Formulation Considerations
| Consideration | Development guidance |
|---|---|
| Formulation route | Water-based and water-rich systems provide the strongest incorporation precedent. |
| Dissolution | Confirm dissolution time, clarity and practical loading with the selected vehicle before scale-up; no validated quantitative solubility value is available. |
| pH and processing | Determine solution pH, finished-formula compatibility and processing stability experimentally. No standard pH window, addition temperature or process limit has been established. |
| Compatibility | Formulation precedent includes aqueous systems containing calcium hydroxymethionine, pentylene glycol, polysorbate 20 and hydroxyethylcellulose. Compatibility should be verified in the complete formulation. |
| Use level | Establish according to the intended function, finished-product safety assessment and performance testing; no general finished-product use level is specified. |
Applications
| Application | Commercial development context |
|---|---|
| Leave-on skin-care complexes | Serums, gels, gel-creams and emulsions developed around a substantiated combination with calcium hydroxymethionine |
| Hydrotrope evaluation | Screening in aqueous personal-care formulas to assess solute-specific water solubilization performance |
| Secondary cleansing systems | Laboratory evaluation as a supporting surface-active ingredient rather than an assumed replacement for a primary surfactant |
Quality & Documentation
The supplier quality specification defines identity, appearance, purity, related substances, sulphate, chloride, heavy metals, arsenic and loss-on-drying limits for catalog NST-10-251.
Raw-material qualification should be combined with application-specific testing of dissolution, compatibility, stability and finished-product performance. The stated raw-material shelf life does not establish stability in a finished cosmetic formulation.
