Embodiment 1

[0063] Recipe 1. Hydrating Body Lotion

[0064]

[0065] Preparation procedure:

[0066] 1. Combine fractions 3 and heat to 80°C.

[0067] 2. Mix part 1 using a propeller mixer, then add part 2. The mixture was heated to 80°C.

[0068] 3. Add part 3 to part 1 and part 2 and keep mixing for 15 min.

[0069] 4. Begin to cool the batch to 45°C.

[0070] 5. Cool to 25°C.

Embodiment 2

[0072] Recipe 2. Foundation

[0073]

[0074]

[0075] Preparation procedure:

[0076] 1. Combine Part 1 and Part 2 with propeller mixing and heat to 80°C until color becomes uniform.

[0077] 2. At 80°C, start propeller mixing of the water in section 3. The remaining ingredients are then added as a slurry along with the butylene glycol and xanthan gum until the batch becomes homogeneous.

[0078] 3. Slowly add Part 3 to Part 1 and Part 2 with propeller mixing until uniform.

[0079] 4. Begin to cool the batch until 65°C.

Embodiment 3

[0081] Recipe 3. SPF 30 Sunscreen Lotion

[0082]

[0083]

[0084] Preparation procedure:

[0085] 1. Combine Parts 1 and heat to 70°C.

[0086] 2. Combine the ingredients of Part 2 into a slurry and add to Part 1 while mixing with the propeller mixer.

[0087] 3. Combine Parts 3 and 4 and heat to 70°C.

[0088] 4. Add part 3 and part 4 mixture to part 1 and part 2 mixture under homogenization.

[0089]5. While cooling, add part 5 with propeller mixing.

[0090] 6. Cool to 40°C, then add part 6 with propeller mixing.

Abstract

Disclosed are personal care compositions comprising acicular titanium dioxide, which block infrared radiation in the NIR spectral range, and methods for making them.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Serial No. 62 / 521,043, filed June 16, 2017, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to infrared attenuation and more specifically to the use of TiO with a specific size and shape 2 Particles, and their use in personal care products, especially those used in sunscreen compositions. The present invention also includes TiO 2 Surface modification of particles. Background technique [0004] The general public and the medical community generally believe that excessive exposure to sunlight can potentially cause skin cancer and premature aging due to the presence of ultraviolet (UV) light. Solar radiation comprises about 5% of ultraviolet (UV) radiation having wavelengths in the range between 200nm and 400nm, which can be further divided into three regions: fro...
