Relevant identified uses of the substance or mixture

Type of use : 
CASTOR OIL 20 EO is Emulsifier for the formulation of plant protection products
CASTOR OIL 20 EO acts as solubiliser for hydrophobic actives, vitamins, perfumes, flavours and essential oils.
CASTOR OIL 20 EO is useful for transparent gel formulations.
CASTOR OIL 20 EO is also used in skin care and transparent cosmetic formulations.

PEG 20 Castor Oil is the Polyethylene Glycol derivatives of Castor Oil, and it functions as a surfactant, a solubilizer, an emulsifier, an emollient, a cleansing agent, and a fragrance ingredient when added to cosmetics or personal care product formulations. 
PEG 20 Castor Oil is a semi-solid ingredient.

PEG-20 Castor Oil is soluble in both water and oil and is traditionally used to emulsify and solubilize oil-in-water formulations. 
Properties of CASTOR OIL 20 EO make it ideal for use in liquid cleansers, and its soothing and softening emollient quality makes it a popular addition to formulations for moisturizers and hair care cosmetics. 
As a surfactant, PEG 20 Castor Oil helps to decrease the surface tension between multiple liquids or between liquids and solids. 
Furthermore, CASTOR OIL 20 EO helps to remove the grease from oils and causes them to become suspended in the liquid. 
This makes it easier for them to be washed away and lends this ingredient popularity in facial and body cleansers. 
As an occlusive agent, CASTOR OIL 20 EO creates a protective hydrating layer on the skin’s surface, acting as a barrier against the loss of natural moisture.

When adding CASTOR OIL 20 EO to cosmetics formulations, it can be blended in its cold state directly into the oil phase at a suggested ratio of 3:1 (PEG 20 Castor Oil to oil). 
Next, this can be added to the water phase. 
If the formula is cloudy, the amount of CASTOR OIL 20 EO may be increased for enhanced transparency.

PEG 20 Castor Oil functions as a(n):
Cleansing Agent
Fragrance Ingredient
PEG 20 Castor Oil helps to:
Combine immiscible ingredients
Gently cleanse and soothe the skin and scalp
Create foam in cleansing products
Offer a consistent thoroughly-blended feel to products

Application and Characteristics
CASTOR OIL 20 EO shows excellent emulsification characteristics for many solvents typically used in agrochemical formulations. 
Besides that, PEG-20 Castor Oil is an environmentally friendly and not eye-irritating product.
CASTOR OIL 20 EO could be used to achieve the following crop protection formulation types: Emulsifiable Concentrate [EC], Emulsion in Water [EW], Suspension Concentrate [SC], Suspoemulsion [SE] and Oil Dispersion [OD]

CASTOR OIL 20 is often used in combination with anionic emulsifier components such as Calcium Labsa and tristrylphenol ethoxylates

PEG-20 Castor Oil is miscible with the standard solvents used for Agrochemical formulations, including vegetable oils and its esters, aromatic solvents, mineral oil, N-alkyl-pyrrolidones, N,N-dimethyl-alkanamides among others.

These characteristics are for guidance only and not to be taken as product specifications. 
The tolerances are given in the product specification sheet. 
For further product properties, specifications, safety and ecological data, please refer to the MSDS.

Typical Use Level of PEG 20 Castor Oil:
As for standard emulsifiers and emulsifier packages,PEG-20 Castor Oil may be used around 5 to 15% with respect to the oil phase. 
Mixing PEG 20 Castor Oil with other emulsifiers might allow to reduce the use level and increase emulsion stability.
