Storage conditions are very important in determining the quality of products as products are not used immediately after production, they have to pass through various storage processes before getting to the end user. The aim of this article is to study the effect of storage on moisturizing creams produced from Delonix regia seed oil (vegetable oil) and mineral oil. Oil in Delonix regia seeds was extracted using cold maceration and their physiochemical compositions were evaluated using AOAC 2016 methods while their elemental mineral components were analyzed using Atomic Absorption Spectrophotometer (AAS). The oils from D.regia and Mineral oil were then used in the production of cosmetic cream products and their physiochemical properties were characterized. Specific gravity, viscosity, refractive index, acid value, peroxide value, iodine value, saponification value and unsaponifiable matter were: 0.99g/cm3, 0.87g/cm3; 47.60, 11.52; 1.4335, 1.5246; 22.44mgKOH/g; 7mgEq/kg; 37.56g/100g; 30mgKOH/g and 2.81, 1.02 respectively. Magnesium (7.56332ppm) was detected as the mineral with the highest concentration in D.regia oil cream while Na (9.4560ppm) was the mineral with the highest concentration in mineral oil cream. For D.regia seed oil cream, the pH, non-volatile matter, and moisture content increased as the storage period increased while the total fatty matter and specific gravity decreased as the storage period increased. For the mineral oil, pH, non-volatile matter and moisture content decreased as the storage period increased while the specific gravity and total fatty matter increased as the storage period increased. This study has indicated that the storage period has a significant effect on the physiochemical properties of moisturizing creams from both Delonix regia seed oil and mineral oil. However, the physiochemical properties are still within the acceptable limits and standard as set by the Standard Organisation of Nigeria (SON).
