INDIVIDUAL PEPTIDES
Acetyl Tetrapeptide-40 is a cosmetic peptide candidate for redness-appearance and skin-comfort formulations. Define the visible endpoint, target area and finished format before comparing materials. Use the identity and preparation review below to make a sample, documentation or quotation enquiry more specific.

Development directions
Redness-appearance and comfort concepts: specify the facial area, cosmetic appearance endpoint and comparison formula. Supplier information on Telangyn concerns a prepared ingredient and an LL-37-induced interleukin model. It does not establish rosacea treatment, permanent removal of visible vessels or results for this catalogue material.
Possible formulation formats
- Redness-appearance facial serum
- Comfort-focused facial cream
- Even-looking-tone cosmetic emulsion evaluation
Formulation concepts for evaluation. Review the actual supplied material and finished formula for the intended cosmetic use.
Identity and supplied form
The Korean Cosmetic Association defines Acetyl Tetrapeptide-40 as the acetylation product of Tetrapeptide-40. This catalogue retains CAS reference 1472633-28-5. Confirm the complete sequence, terminal form, counterions and peptide content from the offered-material documents; the public naming definition does not resolve all of those chemical details.
A cytokine model supports a bounded research question
The Lubrizol-supplied Telangyn listing describes in vitro work on LL-37-induced IL-6 and IL-8 release. This is a laboratory mechanism reference, separate from a human cosmetic appearance assessment. A change in cell-model markers does not establish the size, timing or durability of a visible result in your formula. Request the underlying protocol if that mechanism is central to your project.
Compare the material for your brief
The same supplier listing declares water, Acetyl Tetrapeptide-40 and caprylyl glycol for the reference preparation. Its formulation percentage would refer to that complete preparation. Compare its peptide-content basis with the exact offered form before planning a substitution; neither its carrier system nor its evidence automatically transfers to an individual peptide.
Formulation review priorities
| Review point | What to establish |
|---|---|
| Identity confirmation | Request sequence and terminal-form confirmation alongside the catalogue CAS and full composition; do not select a molecular mass from an unverified name match. |
| Appearance assessment | Define facial area, baseline appearance, matched comparison and observation period for the finished cosmetic. |
| Preparation comparison | Compare peptide content, solvent and preservative systems before interpreting any reference use level. |

Questions for your brief
- Which redness-appearance endpoint and facial area will you evaluate?
- What identity and preparation documents are needed for the offered material?
- What formula stage, sample quantity and destination should the quotation cover?
Does this ingredient listing establish rosacea treatment?
No. This page concerns cosmetic ingredient selection. A laboratory mechanism or cosmetic appearance brief does not establish treatment of rosacea or another medical condition. Define an appropriate cosmetic claim and finished-formula evaluation.
Can I substitute a peptide using the same percentage as a reference solution?
First confirm the complete reference preparation and its peptide-content basis. A solution percentage and an individual-peptide percentage are different quantities. Establish the correct material guidance before preparing or comparing formulas.
