Carnosine (Cosmetic Grade)

Who this page is for

Carnosine identity for cosmetic sourcing

Carnosine is beta-alanyl-L-histidine, a dipeptide formed from beta-alanine and L-histidine. Its two-residue identity differs from the three-residue GHK peptide listed as Tripeptide-1 elsewhere in our catalogue. Use CARNOSINE and CAS 305-84-0 to identify the ingredient for this topical enquiry.

Our nutrition entry concerns the same named substance for a different application; specify cosmetic use when requesting a quotation here. The substance identifier does not by itself describe the impurity profile or the composition needed for a cosmetic formulation. CosIng assigns carnosine a skin-conditioning function, which describes its ingredient role rather than a proven outcome in your finished product.

If your brief names acetylcarnosine, a decarboxylated derivative or a metal complex, give the full identity instead of treating it as this carnosine ingredient. Ask us to confirm the proposed carnosine form and composition against your cosmetic purchasing brief.

Setting a carnosine receiving specification

For cosmetic carnosine, keep identity, measured content and the tests for accompanying substances as separate acceptance items. Request the analytical method and reporting basis for the proposed assay rather than comparing percentages with no method attached. If optical rotation is included in your criteria, specify the solvent, concentration and measurement conditions along with the limit.

Record how any pH value was measured, particularly the concentration of the test solution and its temperature. A raw-material pH result is a test on that preparation; it is not a target pH or compatibility guarantee for your finished cream. Ask your formulator which dissolved-material and appearance checks are needed for a transparent or coloured base.

List relevant impurities and microbiological criteria alongside the carnosine assay in your quality brief. Any batch record should be reviewed against that brief, and we can confirm which matching documents are available when discussing the proposed supply.

From a carnosine sample to the finished cosmetic

For a carnosine sample enquiry, describe whether you are developing a serum, lotion or cream and identify your chosen solvent system. Ask for dissolution data for the actual raw material at a stated temperature before defining a mixing step. Include the planned ingredient concentration, processing time and pH range when reviewing compatibility in the complete base.

Assess your formulation after manufacture and during storage using the packaging intended for the finished cosmetic. Keep microbiological quality and preservation evaluation in that development plan where the formulation requires them. The original Annex I cosmetic safety-information framework covers composition, physical and chemical characteristics, stability and microbiological quality as separate topics.

Before scaling up, agree your carnosine specification and ask what stability information supports the proposed raw-material storage period. Include pack size and expected consumption after opening so handling instructions can be checked against your production schedule. Your enquiry can then connect a defined carnosine material with the tests and formulation conditions that matter to your cosmetic project.

Product identity

INCI name

CAS and formula (verified against PubChem)

Molecular formula and weight describe the substance identified by that CAS number. Confirmation that a specific batch matches this identity comes from the specification sheet and COA.

Specification

Specification: confirmed per inquiry against your target parameters.

Specification, COA, TDS and SDS

Ask for the specification sheet, COA, TDS and SDS of the item and form you are evaluating through Request Technical Documents, and we will confirm which are available.

Certificates: Ask us to confirm whether product-specific certificates are available, their issuer, scope and validity. Certificate copies are not published on this site.

Supply terms

Common specifications are listed for reference. If you need a different specification, send us your target parameters and we will match them from the manufacturers we buy from.
