Entirely vegetable-derived Crodas Crills andCrillets have long-standing food and pharmacopoeia approvals and a safe history of u incosmetic products.As nonionics Crills and Crillets offer many advantages over ionic surfactants such as soapsincluding incread stability formulating flexibility and wider compatibility. They are stableto mild acids alkalis and electrolytes and do not react with ionic ingredients or actives. Bycombining Crills and Crillets at different ratios formulators are able to produce systemswith a wide HLB range to emulsify most cosmetic oils and waxes. Certain Crills and Crilletsare additionally highly effective solubilirs dispersing agents and wetting aids.Functional benefits?? Nonionic emulsifiers and co-emulsifiers?? Solubilirs?? Dispersants??

stable cost effective O/W emulsions a combination of Crill 3 andCrillet 3 is particularly recommended. The ratio of each emulsifier can be adjusted to matchthe required HLB of a wide range of oil pha ingredients. Crill 3 and Crillet 3 can be udfor emulsifying a number of esters mineral and silicone oils. This emulsifying system can beud to formulate thin lotions or thick creams by adjusting the level of fatty alcohol prentor by the u of water pha thickeners. Formulating guidelines for basic systems areprovided overleaf.Combinations
of Crill/Crillet 1 or 4 can be ud in the same way a Crill/Crillet 4emulsifying system is particularly recommended for unsaturated vegetable oils.Typical O/W cosmetic products include moisturising face creams and lotions body lotionsand hand creams aftersuns and cleansing lotions.Water in oil emulsionsCrill 6 and Crill 4 are particularly recommended as emulsifiers for W/O systems. Bothmaterials are bad upon branched or unsaturated lipophiles and are liquid at roomtemperature. Crill 6 is often ud as the sole emulsifier for W/O creams and lotionsparticularly where the external pha is mineral oil. Its low tting point is uful whenformulating emulsions which must remain free from dimentation and crystallisation.W/O emulsions are commonly ud when formulating protective skin creams night andcold creams and baby creams.Pigmented systemsCrill 6 and Crill 4 are recommended as dispersing agents when introducing physicalsunscre
ens and pigments into oily vehicles. Using a dispersing agent results in a moreuniform dispersion and slows agglomeration of particulate materials to give improvedemulsion stability. Applications include sunscreens colour cosmetics and protective babycreams and lotions.Aqueous and aqueous/alcoholic systemsCrillet 1 is an excellent solubilir for fragrance oils oil soluble vitamins and esntial oils.It is a uful ingredient in aqueous systems such as hair gels and spritzes and can helpreduce the levels of alcohol required to solubili fragrances in aqueous/alcoholic productg EDT and aftershaves.Detergent systemsCrillet 1 is widely known to function as a mildness additive in detergent systems and isfrequently ud to formulate gentle baby shampoos.Croda Oleochemicals Personal Care Cowick Hall Snaith Goole East Yorkshire DN14 9AA EnglandTel 44 01405 860551 Fax 44 01405 860205Croda Oleochemicals is a trading name of Croda Chemicals Ltd Croda Leek Ltd and Croda Universal LtdPage 5 of 607/01 DC012/2Formulating guidelines for emulsion systemsIt is well established that a combination of a high and a low HLB emulsifier is often moreeffective than the u of a single emulsifier. Combinations of Crills and Crillets cantherefore be ud to develop stable oil in water emulsions of various materials.Through experimentation it is important to establish the required HLB of the material tobe emulsified and the appropriate chemical type of the emulsifier blend. Selection of theappropriate chemistry is as important as choosing the correct HLB. For exampleemulsifiers with an unsaturated alkyl chain such as an oleyl chain have an
incread affinityfor oils with unsaturated bonds. In this ca a blend of Crill 4 Sorbitan Oleate and Crillet4 Polysorbate 80 would be recommended to emulsify vegetable oils. Similarly a blend ofemulsifiers with saturated alkyl chains for example Crill 3 Sorbitan Stearate and Crillet 3Polysorbate 60 would be appropriate for the emulsification of saturated materials.Most raw materials that are likely to be emulsified eg mineral and vegetable oils emollientesters silicone oils have a published required HLB value. For example required HLB valuesof approximately 10 are usually quoted for mineral oils. In order to develop a stableemulsion of mineral oil a blend of Crill 3 Sorbitan Stearate and Crillet 3 Polysorbate 60combined to give an HLB value of 10 could be evaluated at different concentrations.Further minor adjustments will be required to optimi formulation stability viscosityaesthetics etc.In order to calculate how much of emulsifier A to blend with emulsifier B to reach agiven required HLB of X: A 100 X - HLBBHLBA - HLBB B 100 - ATo calculate the blend of Crill 3 Sorbitan Stearate and Crillet 3 Polysorbate 60 toemulsify an oil with a required HLB of 10:HLB of Crillet 3 14.9HLB of Crill 3 4.7 Crillet 3 100 10 - 4.7 51.515 - 4.7 Crill 3 100 - 51.5 48.5If the required HLB of the material or blend of materials to be emulsified is not
礼的成语known thiscan be determined by experimentation. Evaluation of the stability of emulsions formed withblends of an appropriate Crill and Crillet pair covering a range of HLB values will identifythe requi
red HLB.The optimum concentration of the emulsifier blend can then be determined by experiment.Generally 10-20 of the level of the emulsified material is a uful starting point ie to makea 30 emulsion of oil would usually require an optimum level of 3 emulsifier blend. Bothemulsifiers are usually introduced into the oil pha.Croda Oleochemicals Personal Care Cowick Hall Snaith Goole East Yorkshire
