Varisoft EQ 65
CAS # 67846-68-8, 67762-27-0

Varisoft EQ 65 is a green, readily biodegradable cationic or positively charged ester quat derived from stearic acid and combined with cetearyl alcohol to act as a thickener and conditioning agent for emulsions and hair care products.

Hair care products and lotions made with Varisoft EQ 65 are rich and creamy with the distinctive dry, powdery skin feel of cationic emulsifiers. They are substantive and conditioning to skin and hair, while improving wet detangling and combing, and offering superior dry combing and hair feel.

Varisoft EQ 65 can be used as the primary positively charged ingredient for hair care products such as leave in conditioners, rinse off conditioners, hair masks, and intense treatments, as well as an emulsifier for lotions, creams, and body butters in which you want a green, biodegradable product with a less greasy and smooth skin feel with low tackiness.
Hair care products made with 2% Varisoft EQ 65 offer excellent rinse-ability, increased ease of styling, and increased gloss when compared to 2% Behentrimonium Chloride, and increased hair volume, bounce, dry and wet feel along with dry and wet combing compared to 2% Cetrimonium Chloride. Compared to alkyl quats like Behentrimonium Methosulfate or Stearamidopropyl Dimethylamine, conditioners made with Varisoft EQ 65 weigh hair down less.

Key Benefits

  • ECOcert and COSMOS certified Green and readily biodegradable
  • Increased rinseability, ease of styling, and increased gloss when compared to alkyl quats like Behentrimonium Chloride in hair care products
  • Increased volume, bounce, and improved wet and dry feel as well as wet and dry combing compared to Cetrimonium Chloride in hair care products
  • Reduced weighing down of hair
  • Produces a smooth, less greasy, powdery skin feel in emulsions
  • Increased substantivity and conditioning for skin in body care products


  • Eco and green hair care products, including conditioners, leave in conditioners, and conditioning masks.
  • Eco and green body care products, including lotions, moisturizers, and creams as the emulsifier
  • Sun care and after sun care products due to the smooth skin feel and low tackiness

Formulation Guidelines

  • Varisoft EQ 65 contains cetearyl alcohol as a thickener (65% active distearoylethyl dimonium chloride to 35% cetearyl alcohol), but additional fatty alcohols such as Cetyl or Behenyl Alcohol can be added to increase substantivity and conditioning as well as viscosity. Generally, add 0.5% fatty alcohol for every 1% Varisoft EQ 65 used.
  • In emulsions and conditioners with a small oil phase, Varisoft EQ 65 can be measured into the water phase and heated to 75- 85C (167-176F) along with any other heat tolerant oil or water soluble ingredients or dispersed into the water at 80- 85C (176-185F).
  • Adding non-ionic emulsifiers such as Ceteareth-20 or Olivem 800 (INCI: Ceteareth-6 Olivate) at 1% to 3% will improve the processing of the pellets in water.
  • Preservatives can be added at 40C (104F) with mixing, then allow the product to cool to room temperature.
  • Optimal viscosity can be reached by mixing the product at 30C (86F) or under for 30 seconds to 1 minute.
  • In emulsions and conditioners with a larger oil phase, Varisoft EQ 65 and other oil or silicone soluble ingredients may be heated at up to 85C (185F) while heating the water phase to a similar temperature, before combining and mixing with high shear in a separate container, then combined with the water phase and mixed with high shear. Allow to cool to 40C (104F) before adding preservative, fragrance or essential oils, or other cool down ingredients. Allow the product to cool to room temperature before mixing again for 30 seconds to 1 minute to obtain optimal viscosity.
  • In any product, the pH should be adjusted at the end of the formulating process to pH 4 to 4.5 as it can hydrolyze at pH levels higher than 5. This can be done by adding drops of a solution of 50% Citric Acid Solution and testing until it reaches ideal pH.

Our Customers Say...
I'm completely impressed with not only your selection and prices, but the formulas to help you create the best personal care products. This is the best company I've EVER ordered products from!! I wish us a long and continued business relationship for years to come!!! Thanks!!!
Alexx Daye-Alberson

Lotioncrafter has gotten another customer for life. Their packaging is amazing and the shipping is exceptional. I ordered using USPS first class to Ottawa,ON. It got to me in 7 days (5 business days). That's what I call class!!!

I recently received my latest order from Lotioncrafter, quickly as always, even though it is a very busy time of the year. As usual, the products did not disappoint in any way. I must however comment on this Shea Nilotica I purchased. It is the most amazing shea butter I've ever used and I've tried them all. This shea butter is extremely creamy, softer than any others, with very little scent and has absolutely no graininess. It is truly amazing stuff
Lynne Menard

I love you guys!!! I read about a lot of cutting edge skin care ingredients and whenever I put in my search engine to look for them, you always have them in stock!!! So, I can always count on your company to have the latest and greatest. Thank you, thank you, thank you!!!
Denise Miller

I have been buying products from lotioncrafter since 2012 (I think? maybe longer?).


Because they run a fantastic business, one.

Two, because they are some of the friendliest people in the cosmetic supply business.

Three, because they sell everything at a fair price, which is important when you are sourcing things for a boutique beauty brand like mine.

Four, because they have things I cannot get in small quantities anywhere else.

They are friendly, efficient, sell ethical products and just run a great business. I'm proud to be a customer, I'm glad they are one of my suppliers, and I don't forsee that changing anytime soon. Thanks for being awesome, LotionCrafter!
