MACARE OP is a vegetable derived cosmetic ester designed to impart unique conditioning, emolliency, moisturization, emulsification, thickening, slip, gloss and superfatting in skin and hair care applications. MACARE OP can be formulated to improve the rub-out, spreading, solubilization and skin feel properties for most cosmetics and pharmaceutical ingredients, as well as influence viscosity and dispersion characteristics. MACARE OP is easily formulated to provide a smooth non-greasy elegant feel.

When formulated with mineral oils, MACARE OP improves the feel and slip with levels as low as 2% giving mineral oil a pleasant “talc-powder like,” “silicone” feel while improving formula stability and cost. MACARE OP is an excellent emollient, contributing to enhanced substantivity and skin feel for use in creams, lotions, makeup, baby care, sun care preparations, conditioners, deodorant sticks, bath oils, massage oil, hot pour products such as lipsticks, hair care and ethnic hair care.

MACARE OP is an oil soluble lipid with lubricant, emollient and gloss enhancing properties. MACARE OP improves the spreading, solubilization and skin feel properties for most cosmetics and pharmaceutical ingredients, including pigments and sunscreen actives. These properties improve rub-out of formulations as well as influence viscosity and dispersion characteristics. MACARE OP is easily formulated to provide a smooth non-greasy elegant feel.

MACARE OP can significantly improve the feel and slip of Mineral Oil with levels as low as 2%, giving Mineral Oil a pleasant “silicone” feel.

When formulated with mineral oils and petrolatums, MACARE OP mimics the tactile and sensory properties of silicone based cosmetic formulations while improving formula stability and cost.  The formulation below illustrates a typical application:

Damaged hair, especially permed hair can be difficult to comb, especially when wet. Hair Conditioner products are generally oil-in-water emulsions in which the lipophilic conditioning quaternium ammonium salt is the active ingredient. The conditioning quat, along with the fatty alcohols and Macare OP impart wet-comb performance to the formulation, and contribute to gloss. The superior substantive properties of Maquat BTMC-85%, over other conditioning cationics, significantly improves wet comb performance of these formulas, and others of their type, especially on damaged hair. Enhansys M-100 adds additional moisture retention properties while fortifying the formulation to eliminate the need for preservatives.

MACARE OP is a 100% active liquid with a melting point of ~32°F/0°C. Exercise normal handling precautions by using appropriate eye and skin protection. Contact with eyes and prolonged skin exposure should be avoided. Refer to Material Safety Data Sheet.
