Silk Amino Acids PF   Now Paraben Free!
CAS No. 96690-41-4

Hydrolyzed from pure silk fibers, silk amino acids have a lower molecular weight than hydrolyzed silk protein powders as they undergo a greater degree of hydrolysis.  Due to their smaller molecular weight they are more penetrating and moisturizing to skin and hair. Our Silk Amino Acids have been decolorized and deodorized -- making them an exceptional addition to even the most delicate of formulations. Recommended for formulating shampoos, conditioner, hair treatments, bodywash, body lotions, cleansers, toners and facial moisturizers, mascara, lipstick and color cosmetics.

Silk is taken from the cocoon of the silkworm moth (Bombyx mori) after the moth has emerged from the cocoon following its complete metamorphosis from caterpillar to moth. This is to ensure that no moths are harmed in the harvesting of the silk. After the silk thread is isolated from the vacant cocoon, the fibers are cleaned and degummed. The individual silk fiber, too fine to handle individually, is then wound with other fibers onto a reel creatingone long, strong thread. The threads are then combed to remove the noils. Noils, by-products of the textile industry, are short fibers combed from the long fibers during the preparation of the silk thread. These noils are used in the production of our silk proteins. Our Silk Amino Acids are manufactured from the silk noils by hydrolyzing them down to the free amino acids under carefully controlled conditions.

Note, NO liquid silk amino acids are manufactured without preservatives, including ours.  Preservatives are necessary to maintain the integrity of the raw material.  We have provided the preservative used by the manufacturer below for your reference.

The Shea Nilotica is awesome! Thanks for the sample... that sold me. You have been so helpful and I get so much great information from your site.

Karin Vinci, (Balance of Nature Bath & Body)

Thought that I misplaced my soap bevel when I moved and then could not find the web sight of where the purchase originated. Found the bevel and thank goodness I found the receipt of the purchase!!! Wanted to pass on that it is fantastic and easy to use. It bevels two different sizes and I love it.

I am new to lotion making and was having a hard time figuring out how to use Liquid Germall Plus at the right percentages. I called Jen and she gave me the most informative answer to my question that I've ever received from a company like this. I am very pleased with Lotioncrafter and I will definitely be a return customer.
