Dipeptide-2 CAS 24587-37-9--Effective cosmetic raw material for eye cream and anti-wrinkle serum.Science-Peptide provides high purity dipeptide-2, support kilogram supply, stable quality, has served many cosmetic companies. Welcome to contact us.

Dipeptide-2 (Dipeptide-2) is not a new face in the cosmetic industry, but has been increasingly emphasized by formulators over the years. It is a small molecule dipeptide, simple structure - is two amino acids linked together, small molecular weight, good transdermal properties, mainly used in eye creams and anti-wrinkle products, to help improve puffiness around the eyes, tighten the skin.

 

We have been in the field of peptide synthesis for 20 years, and we are too familiar with small peptides like dipeptide-2. It is not as difficult as those long peptides with dozens of amino acids, but there is a way to achieve stable quality, batch-to-batch consistency, and suitable for cosmetic formulations. We can now supply kilograms of dipeptide-2 with stable purity, and have already supplied it to many cosmetic companies.

The INCI name for Dipeptide-2 is Dipeptide-2, the chemical structure is a dipeptide composed of two amino acids, its main effect is to promote lymphatic circulation, reduce puffiness around the eyes, and improve eye bags.

In cosmetic formulations, dipeptide-2 is commonly found in:

• Eye Cream: focuses on de-puffing and firming the eye area
• Anti-Wrinkle Essence: Combined with other anti-aging ingredients, it improves the skin's elasticity
• Mask: as a potent addition to enhance the firmness of the product

It is often used together with other cosmetic peptides (e.g., Acetyl Hexapeptide-8, Palmitoyl Pentapeptide-4), each with its own division of labor. Dipeptide-2 is mainly responsible for "drainage and firming", hexapeptide is responsible for "dynamic lines", and pentapeptide is responsible for "promoting collagen", each in its own way.

1. Stable supply of kilogram-scale capacity
Cosmetic raw materials are different from pharmaceutical raw materials in that they have large dosage, many batches and sensitive prices. We have run through the amplification process on dipeptide-2, and can stably supply kilograms of products. If you use a few kilograms a month, we can take it and keep supplying it.

2. Stable purity and consistency from batch to batch
Cosmetic formulations are afraid of the fluctuation of raw materials from batch to batch. We do HPLC purity test for every batch of dipeptide-2 to ensure that the purity is stabilized above 98%. Some customers have made comparisons, and the data of three consecutive batches almost coincide with each other, so you can rest assured.

3. Well-documented, formulator-savvy
We provide complete COA reports (purity, molecular weight, moisture, appearance), as well as MS and HPLC profiles if needed. Although these data are not used for declaration, they can be used by formulators for internal quality control.

4. Suitable for addition to formulations
Dipeptide-2 is a lyophilized powder, white powder with good water solubility. We have done the solubility test, in pure water, propylene glycol, glycerol can be dissolved, do not pick solvents. The formulator does not need special treatment, just add it directly.

5. Reasonably priced
We don't do "conceptual" pricing. The dipeptide-2 process is mature, the cost is controllable, and we give a real price in kilograms. We can negotiate for larger quantities.

Production: Solid phase synthesis, each amino acid coupling is monitored. Purification by preparative HPLC to ensure the purity is up to standard. Lyophilized and packaged, protected from light and moisture.
Testing: HPLC purity test and MS molecular weight confirmation are done for each batch. Moisture and appearance are also measured. Data are recorded in COA.
Stability: Long-term stability has been examined, stored at room temperature for 24 months, there is no significant change in purity and appearance. It is used in cosmetic formulations and does not require special storage conditions.
Documentation link: COA report, MS plot, HPLC plot are available. Other documents (e.g. TDS, MSDS) are also available if needed.

Story 1: A cosmetic brand, eye cream formula upgrade
They originally used imported dipeptide-2, the price is high and the delivery time is not stable. They found us and asked us to test the samples, and found that the purity was higher than the imported one, and the solubility was also the same. Tried one kilogram, made a batch of eye cream, stability test, and then switched to use ours. Now we have been purchasing several kilograms every month, and we have been cooperating for two years.

Story 2: An OEM factory, customized for large customers
They received a big order from a brand to make a dipeptide-2 eye cream, and the demand was very high - the first batch needed 10 kilograms of dipeptide-2, and the supplier they had previously found could only supply a few kilograms, so they couldn't take it. We signed a direct order for 10 kilograms and shipped it in two batches, each with a COA, and the factory said, "We were afraid that the supply would be cut off, so we are relieved that you can take the big order."

Story 3: A start-up brand, a lyophilized powder product
They made a dipeptide-2 lyophilized powder, and needed high purity and batch-to-batch consistency of raw materials. We supplied three batches in a row, and the purity of each batch was above 98.5%, with the same impurity profile. Their products have been sold well on line, with many repeat customers, and now they regularly replenish their products every month.

Dipeptide-2 is a mature raw material in cosmetics, not mysterious, but very practical. We have been doing peptides for 20 years, and we have no problem in supplying this kind of small peptide, such as dipeptide-2, with stable process, good quality and kilograms. If you are making eye cream, anti-wrinkle essence, and need a stable supplier of dipeptide-2, welcome to talk with us.
