IO Soothing Complex

This ingredient at a glance

IO Soothing Complex is a colorless to yellow liquid. According to the card, it is completely soluble in PEG oils or polysorbates, mixes with oils and does not dissolve in water. This ingredient is an associated with soothing actives, so it fits products for skin that feels sensitive or uncomfortable. The CoA confirms the INCI and level for each lot.

Working with solubility

Because it is insoluble in water, this ingredient goes naturally into the oil phase of an emulsion or into an anhydrous product. For clear water gels or toners, premix it with polysorbate 20 or a PEG oil before adding water. This simple step keeps the product clear and even.

Product formats

Calming-feel creams

Creams for sensitive-feeling skin are the clearest use. Add this ingredient to the oil phase.

Serums

Oil serums carry it directly. Water serums need a polysorbate premix.

Balms

Anhydrous balms for dry, tight-feeling areas suit it well.

Post-shave care

Light post-shave balms help skin feel comfortable after shaving.

Processing

Add it to the oil phase, or premix it with two to three times its weight of polysorbate 20 for water-based products. Follow the CoA for the level and temperature limits.

Partners

NMF polysaccharide complex adds a water-phase partner. Panthenol, bisabolol and Oat Seed Oil complete a gentle formula. More options sit in our actives catalog.

Testing

Patch tests under dermatological supervision and a sensitive-skin panel support mild wording. Check clarity of gels over time.

Claims

Use comfort wording: skin that feels calm, comfortable and less tight.

Fragrance-free products

Sensitive-skin shoppers often avoid fragrance. Leave it out and say so on the pack.

Original recipe: comfort balm for dry spots, 100 g

Shea butter 35.00 g, beeswax 12.00 g, oat seed oil 25.00 g, caprylic/capric triglyceride 22.00 g, IO Soothing Complex 3.00 g, bisabolol 0.50 g, tocopherol 0.50 g, panthenol in glyceryl caprylate 2.00 g. Melt the butter and wax with the oils at 75 °C, cool to about 50 °C, add the rest and pour.

Sensitive-skin routines

People with sensitive-feeling skin usually prefer short routines with few products. A gentle cleanser, a calming serum and a simple cream cover most needs. Each product should have a short ingredient list and no fragrance. Explaining on the pack that the products were made for sensitive-feeling skin, and listing the tests you ran, helps shoppers choose.

Premix tips

When premixing with polysorbate 20, stir until fully clear before adding to water. Add the premix slowly with gentle stirring. If the gel turns cloudy, the ratio of polysorbate may need to be increased. Keep the ratio in the batch sheet.

Lot records

Compare the color of each new lot with a retained sample, since the liquid can range from colorless to yellow.

Market positioning

Shoppers who research ingredients often recognize trade names and appreciate clear, honest information about why each one is there.

Record the lot number in your batch log so every production run can be traced back to its certificate of analysis. Retain a small sample of each lot for at least the shelf life of the finished product, since it makes later quality questions much easier to answer.

Storage

Store closed in a cool place away from light. Close the container after use.
