Siligel™ by Lucas Meyer Cosmetics is an eco-friendly, green processed gelling agent, stabilizer, co-emulsifier, suspending agent, and skin feel enhancer that decreases transepidermal water loss to keep skin moisturized. As little as 1% increases glide with an ultra-soft after feel with good spreadability on skin. It confers a non-tacky, high glide, silicone-like feel in emulsions and gels without the threading associated with natural gums, like xanthan or guar. It increases efficiency of active ingredients by behaving as a penetration enhancer, and reduces the feeling of tightness in skin cleansers.

Key Benefits
  • Decreases transepidermal water loss
  • Increases efficiency of active ingredients Offers a “silicone like” and ultra-soft after feel from a green processed product
  • Tolerates electrolytes at up to 20%, including sea and spring water
  • Tolerates alcohol at up to 15% and acidic ingredients, like glycolic acid
  • Eliminates pre-dispersion and neutralization
  • Decreases feeling of skin tightness after cleansing
  • Suspends pigments, sunscreens, and exfoliants
  • 100% natural gelling agent

  • Facial products, including sera, gels, light lotions, and masks.
  • Low surfactant cleansing products, including facial washes, “no poo” shampoos
  • Exfoliating products such as low surfactant body and facial cleansers, gelled foot and body scrubs, and light creams
  • Make-up products, such as foundations and concealers
  • Gels including a high salt content, such as aloe vera gel or magnesium oil
  • Gels including a high alcohol content, such a salicylic acid or after shave gels.

Formulation Guidelines

  • Siligel doesn’t require pre-dispersion in cold process products, and is easily incorporated by sprinkling it into the water phase and mixing with high shear mixer, like an immersion blender, our Minipro Mixer, or our MICROMini™ mixer until thickened, up to 15 minutes. As a gelling agent, its thixotropic behaviors allow a gel to be dispensed in a pump or a spray.
  • In emulsions, add it to the heated water phase, then pour the oil into that phase and mix with a high speed mixer. Or add to the end of the emulsion process in the cool down phase and mix until the lotion has a smooth appearance. Final viscosity will be reached in 24 hours.
  • Siligel™ works well as a suspending agent for pigments, sunscreens, and exfoliants. Add the exfoliant or pigment to the gel while mixing with a high shear mixer.
  • Siligel™ can easily incorporate up to 2% oils. It could be used to emulsify up to 10% oils at 1% with high shear mixing, although this is not an optimal usage of this ingredient. 
  • Siligel™ is incompatible with shower gels or shampoo containing more than 5% active anionic surfactants, cationic surfactants, and aluminum salts.
  •  Siligel™ is compatible with sunscreens, pigments, non-ionic surfactants like decyl glucoside, anionic surfactants used at less than 5% active matter, amphoteric surfactants used at less than 5% active matter, glycols, and hyaluronic acid. 
  • Siligel™ can tolerate up to 20% salt, including sodium and magnesium chloride, due to its combination of polysaccharides and phospholipids. It can tolerate up to 15% alcohol; 3% sodium PCA; 0.2% EDTA; and up to 4% glycolic acid (pH 3.5). It’s compatible with many preservatives, including Euxyl PE 9010, parabens, and phenoxyethanol.
  • Siligel™ can be used in products with a final pH of 2 to 10.

Our Customers Say...
I love Lotioncrafter! The shipping is always fast and the description a very good written. Jen even considers my personal wish and ships me the cheapest way always.

Nancy Babbs, (Bellevue Organics)

Thank you for your patience Jenny !
The products were in order and beautifully packed . The Rosehip oil turned out to be the bonus ingredient ...beautiful, aromatic and so , so light ! Thank you for your excellent products and for making it so easy for a newbie like me.

Lotioncrafter is absolutely my favorite supplier. They have one of the most extensive collections of ingredients around. And I have not found anyone else who can even come close to beating their prices or their quality! They also have great shipping. However much I figure shipping is going to cost for my order, it always comes to less than I thought. If I order on Monday night, I get the email telling me my order has shipped Tuesday at 10 am. The order then arrives at my door on Friday. Lotioncrafter orders arrive so much faster and cost less than other suppliers! Which is great for me, as it is so hard for me to wait for my orders to arrive. Lotioncrafter, you're a pleasure to do business with! I couldn't be more pleased with your service.

I am a newbie at lotion malling and really appreciate the information provided by Lotioncrafters. I purchased Lotion Making 101 and Jenny was kind enough to make sure I got the ebook without having to use my ancient desktop. I highly recommend the book. It makes the process and ingredient possibilities very clear. And the quick shipping is fabulous. Again, thank you.
