Answers to Your Formulation Questions

Here are the answers to your questions regarding cosmetic formulations:

Ingredient Compatibility and Usage

• Vitamin B3 (Safe B3) with Pitera and Arbutin: Yes, you can generally combine Safe B3 (Vitamin B3) with Pitera (Galactomyces Ferment Filtrate) and mix it with Alpha Arbutin. This combination is considered compatible.

• BHA + Vitamin B3 Toner before LHA Serum: It is not recommended to use BHA (Salicylic Acid) and LHA (Capryloyl Salicylic Acid) sequentially or together. They function through similar mechanisms, and using both does not provide significant additional benefits. If you need stronger exfoliation or acne treatment, consider using alternative ingredients with different modes of action.

• ALA or BHA with Alpha Arbutin: Acidic ingredients like ALA (Alpha Lipoic Acid) and BHA (Salicylic Acid) can potentially affect the stability of Alpha Arbutin due to pH differences. While sequential application on the skin might not cause immediate complete degradation, it is safer to apply them at different times of the day (e.g., BHA/ALA at night and Alpha Arbutin in the morning) or wait 15-30 minutes between applying the acidic product and the Alpha Arbutin product.

• Vitamin C (Stabilized Vitamin C (Natural-C Glycol™)) with Alpha Arbutin: Stabilized Vitamin C (Natural-C Glycol™) is acidic, while Alpha Arbutin requires a higher pH for stability. Therefore, these two ingredients should not be mixed together in the same formula. To use both, it is best to apply them at different times, such as applying Stabilized Vitamin C (Natural-C Glycol™) at night and Alpha Arbutin in the morning.

Formulation Requests

• Silicone-Free CC Cream for Sensitive Skin: To create a silicone-free CC cream base suitable for sensitive skin, you can use Light Cream Maker as an emulsifier and thickener. To adjust the texture for a lighter feel, you might incorporate ingredients like MatteSilica or PowderCream. For color and coverage, you can add powders such as Mica and BB Micro Silk.

• Serum Formula for Acne-Prone Skin: Generally, any oil-free serum can be suitable for acne-prone skin. Without more specific requirements, a detailed formula cannot be provided. The key is to avoid oil-based ingredients.

• Silicone-Free and Oil-Free Sunscreen Formula: Formulating an effective silicone-free and oil-free sunscreen requires specialized knowledge regarding UV filters and base ingredients to ensure proper dispersion, stability, and sun protection without silicones or oils. A specific formula cannot be provided.

• Lip Stain Formula (Silicone-Free, Dries Well): Creating a silicone-free lip stain that dries and adheres well involves selecting specific waxes, film-formers, and pigments. A detailed formula cannot be provided without further information on desired properties and available ingredients.

Other Questions

• Dissolving Propolis Resin without Alcohol: Information on dissolving sticky resin Propolis without using alcohol is not available. It is recommended to contact the manufacturer of the Propolis you have for specific instructions.

• Availability of Fermented Algae ("สาหร่ายบ่ม"): I do not have access to real-time stock information and cannot provide an update on the availability of Fermented Algae.

Remember that successful cosmetic formulation requires careful consideration of ingredient compatibility, stability, and safety. Always perform proper testing when creating new formulations.
