The Silk Amino Acids PF (Paraben-Free) with CAS Number 96690-41-4, combined with water (CAS Number 7732-18-5), are hydrolyzed from pure silk fibers. Silk amino acids, having a lower molecular weight compared to hydrolyzed silk protein powders due to a greater degree of hydrolysis, are known for their enhanced penetration and moisturizing effects on both skin and hair.
Key characteristics and benefits of Silk Amino Acids PF:
1. **High Amino Acid Concentration:** This product has a high concentration of amino acids, particularly glycine, alanine, and serine.
2. **Tyrosine Removal:** The bulk of the less soluble amino acid, tyrosine, has been removed.
3. **Skin and Hair Substantivity:** Silk Amino Acids PF are highly substantive to both skin and hair.
4. **Hygroscopic Properties:** These amino acids are highly hygroscopic, meaning they attract and retain moisture effectively.
5. **Moisture Binding:** They exhibit excellent moisture binding ability, drawing moisture into the skin and hair.
6. **Penetration:** Free amino acids are known to penetrate the upper layers of the skin and the hair cuticle, improving hydration in these areas.
Applications:
- Shampoos, conditioners, hair treatments
- Body wash, cleansers
- Body creams, lotions, and gels
- Facial toners and moisturizers
- Mascara, lipstick and color cosmetics
- Nutritive products for brow and lash
Note, NO liquid silk amino acids are manufactured without preservatives, including ours. Preservatives are necessary to maintain the integrity of the raw material.
The preservative system used for this product is ECOCert approved for use in Certified Organic products.
NOTE: Due to temperature shifts during shipment of protein products, containers may become slightly bloated. Lotioncrafter recommends venting the built-up oxygen. This is done by slowly loosening the cap to allow the pressure to carefully escape. The cap should be kept on during the venting process. Once all the pressure is released, the cap should be resealed immediately. In order to avoid contamination, please ensure that nothing is inserted into packaging during the venting process.
